3D Swing AnalysisAdvanced3D swing analysis reconstructs the golf swing in three-dimensional space from motion capture or multi-camera video, letting angles like hip rotation or spine tilt be measured directly instead of estimated from a flat, single-angle image.Golf
AceBeginnerAn ace is a legal serve the receiver fails to touch with the racquet, winning the point outright. The headword "ace" is used as-is across languages.Tennis
Address PositionBeginnerAddress position is the complete setup posture a golfer takes just before starting the swing. This means grip, stance, alignment, ball position, posture, and weight distribution all combined into one starting frame.Golf
Adjustable Driver HoselIntermediateAn adjustable driver hosel lets a golfer change the loft (typically ±1° to ±2°) and sometimes the lie angle or face angle at the connection between shaft and head, without buying a new club.Golf
Adjusting to a Flat ArcIntermediateAdjusting to a flat arc means triggering the swing slightly earlier and using a flatter bat path to match a pitch that peaks closer to the legal minimum and arrives faster with a shallower descent.Slow-Pitch Softball
Adjusting to a High ArcIntermediateAdjusting to a high arc means delaying the swing trigger and slightly steepening the bat path to match a pitch that peaks near the legal maximum and descends sharply into the zone.Slow-Pitch Softball
Adjusting to Speed ChangesIntermediateAdjusting to speed changes is a hitter's ability to recalibrate load and swing timing mid-at-bat when a pitcher mixes in a slower pitch after establishing a faster one. This involves avoiding the classic "way out in front" miss on a changeup.Fast-Pitch Softball
Age vs Level (Scouting)IntermediateAge vs level is the practice of evaluating a player's performance relative to how old they are compared to the competition they are facing, since being young for a level is generally a positive sign and being old for a level tempers otherwise strong numbers.Baseball
Aggressive Baseline PlayIntermediateAggressive baseline play is a style built around taking the ball early, hitting with pace and depth from the baseline, and dictating rallies rather than waiting for opponent errors.Tennis
Ahead vs Behind in the CountBeginnerBeing ahead in the count means the hitter has more balls than strikes (a "hitter's count"). Being behind means the pitcher has more strikes than balls (a "pitcher's count"). This means and both hitter and pitcher strategy shift meaningfully depending on which side is ahead.Baseball
AI Swing ReportBeginnerThe AI Swing Report is the comprehensive analysis document SwingVantage generates after processing your video, combining the deterministic engine's findings with optional AI-enhanced commentary into a single, prioritized report.Analysis Concepts
AI-Enhanced AnalysisBeginnerAI-Enhanced Analysis is the optional second layer of SwingVantage's analysis pipeline. This means added on top of the deterministic heuristic result. This means that uses an AI language model to generate contextual explanation, drill language, and coaching narrative.Analysis Concepts
Aim PointAdvancedAim point green reading uses the feet to feel slope percentage underfoot, then converts that number into a finger-count aim spot near the hole. This means a systematic, feel-based alternative to purely visual break reading.Golf
AlignmentBeginnerAlignment is the direction the body and clubface are aimed at address. Poor alignment is one of the most common causes of off-target shots even with a good swing.Golf
All-Court Game StyleAdvancedAn all-court game blends baseline power, net approaches, serve-and-volley, and touch shots, adapting the tactical plan to the specific opponent and match situation rather than relying on one style.Tennis
Analysis Confidence LevelIntermediateAnalysis confidence level is a stated measure of how reliable a video-derived swing observation is, based on factors like camera angle, lighting, and frame rate. This means a safeguard against presenting a rough estimate as a certain fact.Golf
Analysis JobIntermediateAn Analysis Job is the traceable processing record created each time you submit a video or session for analysis. This means it tracks status (queued, running, complete, failed), the inputs used. The outputs produced.Analysis Concepts
Analysis ParalysisIntermediateAnalysis paralysis is trying to consciously monitor too many mechanical details during a swing at once. This interferes with the largely automatic motion a well-practiced swing is supposed to be.Golf
Anticipation and Reaction TimeIntermediateAnticipation is reading cues from an opponent's preparation, body position, and court positioning before contact to start moving earlier, effectively buying more time than raw reaction speed alone provides.Tennis
Approach ShotBeginnerAn approach shot is any shot hit toward the green with the intent of reaching or setting up the putting surface, most commonly the second shot on a par 4 or the second or third shot on a par 5.Golf
Approach ShotIntermediateAn approach shot is struck off a short ball as the player moves toward the net, designed to put the opponent under pressure. At the same time, allowing time to close into a volley position.Tennis
Approach to Kitchen LineIntermediateThe approach to the kitchen line is the movement pattern used to advance from the baseline to the non-volley zone after a third-shot drop or drive. This means typically using split steps to arrive balanced and ready.Pickleball
Approach to NetIntermediateApproaching the net is the tactical decision to move forward from the baseline toward the net after an approach shot or serve, aiming to put away the point with a volley or overhead.Tennis
Approaching the Net After ServeIntermediateApproaching the Net After Serve is the specific footwork sequence a server uses to move from the service line to the net zone in the two or three steps immediately following the serve, timed. As a result, the server is settled and split-stepping just as the return is struck.Padel
ArcBeginnerThe arc is the high, looping flight path a legal slow-pitch delivery must follow. USA Softball requires a peak between 6 and 12 feet. USSSA instead requires at least 3 feet of arc above the release point and caps height at 10 feet above the ground. Hitters time their swing to the ball's descent, not its rise.Slow-Pitch Softball
Arc Height RegulationBeginnerArc height regulation defines the required minimum and maximum height a slow-pitch delivery must reach. This means typically 6 to 12 feet. This means to be called a legal pitch.Slow-Pitch Softball
Arm AngleIntermediateArm angle is the vertical orientation of the throwing arm at release. This comes from over-the-top through three-quarter, sidearm, to submarine. This means and it shapes both the pitch plane and movement profile.Baseball
Arm Care RoutineBeginnerAn arm care routine is a set of general warmup, mobility, and strengthening exercises a throwing athlete performs regularly. This means typically before and after throwing. This means as part of a general, ongoing throwing-health practice.Baseball
Arm CircleBeginnerThe arm circle is the full 360° rotation of the pitching arm around the shoulder joint that defines the fast-pitch windmill delivery and stores elastic energy for release.Fast-Pitch Softball
Arm Slot (Fielding)IntermediateA fielder's arm slot is the arm angle at release when throwing. This means the natural slot that produces the most accurate and arm-safe throw for that player's anatomy.Baseball
Arm SwingIntermediateThe arm swing is the movement of the arms across and around the body during the golf swing. This must coordinate with body rotation to produce a consistent, powerful arc.Golf
Around-the-Post (ATP)AdvancedAn around-the-post (ATP) is a legal shot hit around the outside of the net post rather than over the net. This means the ball may pass the post at any height. It is triggered when a sharply angled ball pulls the player outside the sideline. This creates a geometry where going around the post is the only way to return the ball into the opponent's court.Pickleball
Around-the-Post Angle JudgmentAdvancedAround-the-post angle judgment is the skill of recognizing when a wide ball can legally be hit around the net post. This means below net height and outside the sideline. Instead of over the net.Pickleball
Ascending BlowIntermediateAn ascending blow is contact made. At the same time, the clubhead is still moving upward relative to the ground, the intended angle of attack for a driver teed up, and generally undesired for iron shots struck off the turf.Golf
Attack AngleAdvancedAttack angle is the vertical direction the clubhead is moving at impact. Negative means hitting down on the ball; positive means hitting up.Golf
Attack Angle (Batting)AdvancedAttack angle in batting is the vertical angle of the bat path through the hitting zone. A slightly upward attack angle (+5° to +15°) matches the pitch plane for hard contact.Baseball
Attackable BallIntermediateAn attackable ball is any shot that sits above the net tape when the opponent contacts it. This gives them the geometric ability to drive or speed-up downward.Pickleball
Attacking a Short LobIntermediateAttacking a short lob means recognizing the moment a lob falls short of the back court. This means landing inside the service line and reaching well above head height. This means as the clearest attacking window in padel, where a smash, rulo, or aggressive overhead should be chosen over a cautious, position-preserving response.Padel
Australian Formation (Doubles)AdvancedThe Australian formation has the server and net partner start on the same side of the court, taking away the returner's easy crosscourt return and forcing a down-the-line reply.Tennis
Back GlassBeginnerThe Back Glass is the tall transparent wall at each end of a padel court. This players use intentionally to extend rallies by letting shots rebound back into play.Padel
Back-Foot PlayBeginnerBack-foot play is batting in which the batter moves the weight back and onto the rear foot to play short-pitched or rising deliveries. This creates time by moving away from the pitch of the ball.Cricket
Back-Side MechanicsAdvancedBack-side mechanics refer to how the trail hip, knee, and foot fire through the swing. This means the "engine" side that drives rotational power from the ground up through the barrel.Slow-Pitch Softball
Backdoor Breaking BallAdvancedA backdoor breaking ball starts outside the strike zone, away from an opposite-handed batter, and breaks back over the outside corner for a called strike, appearing to be a ball until the last instant.Baseball
Backdoor RiseAdvancedA backdoor rise ball is thrown off the outer edge of the plate that appears to be off the corner but late rotation carries it back over for a strike, fooling hitters who lay off it.Fast-Pitch Softball
BackhandBeginnerThe backhand is a groundstroke hit on the non-dominant side of the body, played either with one hand or two, and can be struck flat, with topspin, or as a slice.Tennis
Backhand DinkBeginnerA backhand dink is a soft, controlled shot hit on the non-dominant side of the body with a compact, low-to-no backswing, arcing just over the net into the kitchen.Pickleball
Backhand FieldIntermediateFielding a ground ball backhand means catching it with the back of the glove hand turned toward the ball. This involves reaching across the body rather than squaring up in front of it.Baseball
Backhand GripIntermediateThe Backhand Grip in padel is a slight rotation of the Continental toward the Eastern Backhand position, used by some players to generate more topspin and racket-face stability on two-handed or single-handed backhand drives.Padel
Backhand Slice GripBeginnerThe backhand slice grip is typically a continental or mild eastern-backhand grip that opens the racquet face naturally, supporting the high-to-low swing path used to produce underspin.Tennis
Backing Up a ThrowBeginnerBacking up a throw means a defender not directly involved in a play moves into position behind the receiving fielder to stop an overthrow from turning into extra bases.Slow-Pitch Softball
Backing Up BasesBeginnerBacking up bases is the responsibility of defenders not directly involved in a play to position themselves behind a base or the catcher in case a throw is overthrown or misplayed.Fast-Pitch Softball
BackliftBeginnerThe backlift is the upward movement of the bat before the batter plays a stroke. This means the height, direction, and angle of the backlift influence bat path and ultimately the direction of the shot.Cricket
Backspin (Batting)IntermediateBackspin in batting is the rotation imparted on a batted ball when contact is made slightly below its center. This means the same Magnus effect that keeps a well-struck fly ball or line drive carrying rather than diving.Baseball
Backspin ContactIntermediateBackspin contact is squaring the ball near its center-to-lower half with a barrel path angled slightly upward. This produces rotation that helps the ball carry farther and hold a line-drive trajectory.Slow-Pitch Softball
BackswingBeginnerThe backswing is the movement of the club from address to the top position. Its purpose is to create the width, shoulder turn, and wrist hinge needed to generate power on the way down.Golf
Backswing-to-Downswing RatioIntermediateBackswing-to-downswing ratio is the precise, frame-counted timing measurement of a swing's two halves, used by video analysis tools to track a golfer's tempo objectively across sessions rather than by feel.Golf
Bad HopBeginnerA bad hop is a ground ball bounce that deflects unpredictably off a seam, rock, or divot in the infield, changing direction or height at the last instant before it reaches the fielder.Slow-Pitch Softball
BajadaAdvancedA bajada (Spanish for "descent") is an attacking shot played after the ball rebounds off your own back glass, taking it on the way down to drive it hard and low past the net opponents. This means converting a defensive rebound into an offensive transition.Padel
Bajada TimingAdvancedBajada timing is the specific rhythm cue coaches use to teach the bajada's contact window. This means count the ball's rise off the back glass, its peak, then its descent, and strike only on the way down. This means. This is because contacting even slightly early turns a potential attacking shot into an unforced error.Padel
BalanceBeginnerBalance in a swing context is the ability to maintain a stable base and controlled center of mass through the full motion. This comes from setup through the end of the follow-through.Analysis Concepts
Balance Through ContactIntermediateBalance through contact means the body's center of mass stays controlled and stable through the moment of impact, even. At the same time, moving. This allows the swing to transfer its full power and direction into the ball.Tennis
BalkIntermediateA balk is an illegal or deceptive motion by the pitcher. At the same time, runners are on base, immediately awarding every runner one base without a pitch needing to be thrown.Baseball
Ball BlockingIntermediateBall blocking is the technique of dropping to the knees to smother a pitch in the dirt. This prevents wild pitches and passed balls that would allow baserunners to advance.Fast-Pitch Softball
Ball CompressionIntermediateBall compression is how much the golf ball deforms against the clubface at the moment of impact, with more effective compression (from clean, centered, descending contact) producing more efficient energy transfer and a more penetrating flight.Golf
Ball Flight LawsIntermediateThe ball flight laws are the set of physical variables at impact. This means face angle, swing path, angle of attack, strike location, dynamic loft, and clubhead speed. This means that together determine every trait of a shot's flight.Golf
Ball Flight Off the BatBeginnerBall flight off the bat is the combination of exit speed, launch angle, and spin that together determine whether a batted ball travels as a line drive, ground ball, fly ball, or pop-up.Slow-Pitch Softball
Ball PositionBeginnerBall position is where the ball sits in your stance — from the front foot for a driver to the center for short irons. It directly controls the low point and attack angle.Golf
Ball Position — DriverBeginnerDriver ball position sits forward in the stance, typically off the lead heel or slightly inside it. As a result, the club meets the ball on the upswing after the low point of the swing arc has already passed.Golf
Ball Position — IronsBeginnerIron ball position moves progressively back in the stance as the clubs get shorter. This comes from just forward of center with long irons to closer to center with short irons and wedges. This means supporting the slightly descending strike irons require.Golf
Ball ReceivingBeginnerBall receiving is the technique of catching pitched balls cleanly and quietly. This means presenting them to the umpire in a way that reinforces strike calls and prepares for an immediate throw if needed.Fast-Pitch Softball
Ball SpecificationsBeginnerStandard slow-pitch softball specifications call for a 12-inch circumference ball with a defined COR and compression rating. Men's and co-ed leagues commonly use a 12-inch ball; some senior and mixed leagues use an 11-inch ball.Slow-Pitch Softball
Ball SpeedIntermediateBall speed is how fast the ball leaves the clubface, measured in miles per hour. It is the single biggest driver of carry distance.Golf
Ball Speed LegalityAdvancedOnly balls that pass an official approval process. This means meeting standardized bounce, hardness, and durability testing. This means are legal for sanctioned tournament play, similar to how paddles are certified.Pickleball
Ball TransferIntermediateBall transfer is the exchange of the ball from the glove to the throwing hand. This means speed and consistency here is one of the biggest separators in infield and catcher efficiency.Baseball
Ball-First ContactIntermediateBall-first contact means the club strikes the ball before it reaches the ground, the fundamental requirement for a clean, compressed iron or wedge shot.Golf
BallooningIntermediateBallooning is when a shot. This means typically a driver. This means climbs steeply into the air and stalls, losing distance. This is because of excessive spin rate and too-high launch angle.Golf
Banana SliceBeginnerA banana slice is the exaggerated, wide left-to-right curve. This means usually starting near or left of target and bending hard right. This means most associated with beginner and high-handicap golfers.Golf
BandejaIntermediateA bandeja is a controlled sliced overhead. This means Spanish for "tray". This means hit to maintain net position. At the same time, placing the ball deep with backspin, prioritizing position preservation over outright winning the point.Padel
Bandeja vs Vibora DecisionAdvancedThe bandeja-versus-víbora decision is the split-second read a net player makes on a moderate lob. This means one too deep to smash but not defensive enough to simply reset. This means defaulting to the bandeja's safety and position-holding when in doubt, or choosing the víbora's added pressure when the lob, footing, and score situation justify the extra risk.Padel
BarrelAdvancedA barrel is a batted ball combining high exit velocity with an optimal launch angle at the same time. This means the exact combination most likely to produce extra-base hits.Baseball
Barrel AccuracyAdvancedBarrel accuracy is how reliably a hitter makes contact on the sweet spot of the bat rather than the handle or end cap. This means a coaching-level read on contact-point precision, distinct from the formal "barrel" batted-ball classification.Baseball
Barrel PathIntermediateBarrel path is the trajectory the barrel of the bat travels through the hitting zone. This means matching it to the pitch plane for as long as possible maximises the chance of hard contact.Baseball
Barrel Path (Slow-Pitch)IntermediateBarrel path is the trajectory the bat head travels from the load through contact and extension. This means the single biggest factor in matching a slow-pitch hitter's swing to the ball's steep descending arc.Slow-Pitch Softball
Base RunningIntermediateBase running in slow pitch encompasses reading the ball off the bat. This involves knowing when to advance aggressively and when to hold, and making smart decisions that turn singles into extra-base opportunities.Slow-Pitch Softball
Baseball IQIntermediateBaseball IQ is a player's situational awareness and decision-making. This means knowing where to throw the ball, when to take an extra base, how to position defensively, and what the game situation calls for, separate from raw physical tools.Baseball
Baseline GameBeginnerA baseline game is a tactical style where the player controls points from the back of the court. This uses deep, consistent groundstrokes to move the opponent and create openings without approaching the net.Tennis
Baseline MeasurementBeginnerA baseline measurement is the first recorded data point for a metric, captured before training begins, that all future improvement is measured against.Analysis Concepts
Baseline PlayBeginnerBaseline play refers to deliberately staying near the back of the court. This uses drives and drops rather than advancing to the kitchen, often as a defensive or reset strategy.Pickleball
Baseline SwingIntermediateA baseline swing is a recorded reference swing captured before starting work on a specific change, used as the fixed comparison point every later retest is measured against.Golf
Baserunning ReadIntermediateA baserunning read is the split-second decision a runner makes based on what the ball does after contact — whether to advance, hold, or retreat.Baseball
Bat CertificationBeginnerBat certification is official approval from a sanctioning body (ASA/USA Softball, USSSA, NSA, ISA, etc.) confirming a bat meets performance and safety standards for league play.Slow-Pitch Softball
Bat DragIntermediateBat drag is a sequencing fault where the hands fire toward the ball well ahead of the barrel. This leaves the barrel trailing behind and forcing it to catch up late. This means costing bat speed and forcing contact deep and off the sweet spot.Baseball
Bat Drag (Slow-Pitch)IntermediateBat drag is when the hands and body rotate ahead of the barrel. This leaves the bat head trailing behind through the swing and forcing late, weak, or off-line contact.Slow-Pitch Softball
Bat LengthBeginnerBat length is measured in inches from knob to end cap. Most adult slow-pitch bats run 34 inches; a longer bat adds reach and potential leverage but is harder to control.Slow-Pitch Softball
Bat PathBeginnerBat path is the three-dimensional route the barrel travels from load to finish. This means its shape through the hitting zone, more than raw bat speed, decides whether contact is hard or weak.Baseball
Bat PathIntermediateBat path is the trajectory the barrel travels through the hitting zone. This means ideally a slightly upward, direct line that maximizes the time the barrel stays in the plane of the pitch.Fast-Pitch Softball
Bat SpeedIntermediateBat speed is how fast the barrel is moving at contact, in mph. It contributes to exit velocity alongside bat path and where on the barrel you make contact.Baseball
Bat Speed (Slow-Pitch)IntermediateBat speed is how fast the barrel is traveling at the moment of contact, driven primarily by hip-to-hand sequencing and rotational mechanics rather than upper-body strength alone.Slow-Pitch Softball
Bat Speed Ejection RuleIntermediateThe bat speed ejection rule is the penalty many sanctioning bodies apply. This means typically the batter being called out, and in some cases the batter or even the entire team being ejected from the game. This means when a bat is found on the field to be decertified, altered, or otherwise non-compliant with the association's testing standard.Slow-Pitch Softball
Bat Weight / DropBeginnerBat weight is measured in ounces. The "drop" is the difference between length (inches) and weight (ounces) — a 34-inch, 26-ounce bat is a drop -8. Most adult slow-pitch bats weigh 26–28 ounces.Slow-Pitch Softball
Bat-to-Ball SkillBeginnerBat-to-ball skill is a hitter's ability to make solid contact reliably. This means tracking the pitch, timing the swing, and getting the barrel to the ball. This means independent of how hard the ball is hit once contact is made.Baseball
Batting GlovesBeginnerBatting gloves are thin gloves worn on one or both hands while hitting to improve grip, reduce vibration, and protect against blisters during long sessions.Slow-Pitch Softball
Batting OrderIntermediateThe batting order is the set sequence in which players take their at-bats. In slow pitch, the order is constructed to put the best on-base threats at the top and the most powerful hitters where they can drive in runs.Slow-Pitch Softball
Beginner Mistake: Not Using the WallsBeginnerNot Using the Walls is the beginner tendency to treat every ball heading toward the glass as a shot to intercept immediately, rather than letting it rebound and playing the calmer ball that comes off the wall. This means the single habit that separates padel beginners from everyone else who has adjusted to the sport.Padel
Beginner Mistake: Smashing Every LobBeginnerSmashing Every Lob is the beginner habit of attacking every overhead ball at full power regardless of height, position, or court situation. This produces a high rate of unforced errors compared to selectively choosing when a smash is actually the right shot.Padel
Beginner Mistake: Standing Too DeepBeginnerStanding Too Deep is the beginner habit of camping near the back glass throughout a rally instead of advancing to the net when the point allows it. This surrenders the net advantage that decides most points in padel.Padel
Beginner Rule Confusion: Can the Ball Hit the Wall FirstBeginnerNo. This means during a rally, a ball crossing to your side of the court must bounce once on the ground before it can legally touch a wall. A ball that hits your back or side glass before bouncing on the ground is a lost point for your side.Padel
Beginner Rule Confusion: Serve Bounce RuleBeginnerThe padel serve requires the server to bounce the ball once on the ground themselves behind the baseline and strike it at or below waist height. At the same time, it is still dropping or just after the bounce. This means not toss it up and hit it in the air like a tennis serve.Padel
Beginner Rule Confusion: Stepping in the Kitchen After a VolleyBeginnerThe confusing part of this rule is timing. This means momentum carrying a player into the kitchen as a continuation of the volley motion is a fault. But stepping into the kitchen after the shot is fully finished and the player has regained balance is completely legal.Pickleball
Beginner Rule Confusion: When You Can VolleyBeginnerVolleys are illegal on the serve and the return of serve until each has bounced once under the two-bounce rule. After that, a volley is legal from anywhere outside the non-volley zone for the rest of the rally.Pickleball
Beginner Slice FixBeginnerFor most beginners, a slice comes from an open clubface relative to an out-to-in swing path. The fastest fix is usually strengthening the grip and feeling the club swing more from inside the target line, not swinging "harder" or "straighter."Golf
Bellied WedgeIntermediateA bellied wedge is contact made with the leading edge striking the ball around its middle rather than the sole and face engaging lower. This produces a low, running shot that is less severe than a full skull but still an unwanted mis-hit.Golf
BenchmarkIntermediateA benchmark is a reference value that defines acceptable or optimal performance for a given metric, used to judge your data against the right standard for your sport and skill level.Analysis Concepts
BertProA bert is a doubles variant of the erne where a player jumps around the kitchen post from the opposite side of the court, crossing in front of their partner to contact the ball outside the NVZ.Pickleball
Best Ball vs Scramble FormatBeginnerIn best ball, each teammate plays their own ball throughout the hole and the team counts the lowest individual score. In a scramble, everyone tees off and the team picks the best shot, then all players hit their next shot from that same spot.Golf
Big Inning TheoryIntermediateBig inning theory holds that slow-pitch games are decided by one inning of 5+ runs rather than evenly distributed scoring. This means. As a result, strategy should prioritize keeping rallies alive over individual sacrifice plays.Slow-Pitch Softball
Birdie and Eagle ExplainedBeginnerA birdie is a score of one stroke under par on a hole. An eagle is two strokes under par. This means both are notable, celebrated results that most golfers, even good ones, make only occasionally.Golf
Blade PutterBeginnerA blade putter has a slim, classic head shape with less perimeter weighting than a mallet, and is more often toe-hang balanced. This means a design that suits golfers with a natural arcing stroke and a preference for feel and feedback.Golf
Blade vs. Cavity BackIntermediateBlades (muscle backs) concentrate mass behind the sweet spot for feel and workability. Cavity backs move mass to the perimeter for a larger sweet spot and higher forgiveness on mishits.Golf
Bladed IronIntermediateA bladed iron is a severe thin strike where the leading edge, not the face, contacts the ball. This produces a low, hard, running shot with essentially no spin or control. This means the full-swing counterpart to a skulled chip.Golf
Block PracticeIntermediateBlock practice is repeating the same shot with the same club to the same target over and over. This builds a new motor pattern quickly but transfers less reliably to the varied conditions of an actual round.Golf
Block ReturnIntermediateA block return uses almost no backswing at all, absorbing the serve's pace with a firm, stable racquet face to redirect the ball back deep.Tennis
Blocked PracticeIntermediateBlocked practice is repeating the same skill or shot in the same conditions many times in a row. This means effective for initial skill acquisition but less effective for long-term retention than varied practice.Analysis Concepts
Blocked PushIntermediateA blocked push is a straight shot that starts and stays right of target with almost no curve. It is caused by a clubface that matches an in-to-out path but the whole delivery is aimed too far right.Golf
BlockingAdvancedBlocking is when the arms and club fail to fully release through impact. This means the face is held open and the ball flies straight right (for a right-hander) with no draw curve.Golf
Blocking a Pitch (Catching)IntermediateBlocking is a catcher's technique for smothering a pitch in the dirt with the body and chest protector. Instead of trying to catch it with the glove, to keep the ball in front and prevent a passed ball.Baseball
Blocking a Speed-UpIntermediateBlocking a speed-up is a defensive volley technique that absorbs the pace of an incoming attacking shot with a firm, still paddle face rather than swinging back at it.Pickleball
Bloop Hit CoverageIntermediateBloop hit coverage is the defensive assignment structure. This means usually shared between an infielder, the short fielder. An outfielder. This means for the shallow no-man's-land zone where descending-arc pitches most often produce soft contact.Slow-Pitch Softball
Body ServeIntermediateA body serve is aimed directly at the returner's torso or hip, denying them room to swing freely and forcing a cramped, defensive return.Tennis
Body ServeIntermediateA Body Serve in padel is a serve directed at the receiver's body. This means typically at the hip or shoulder on the dominant side. This means to jam the swing and prevent a clean, aggressive return.Padel
Body Shot AttackIntermediateA body shot attack is a speed-up or drive aimed directly at the opponent's torso or dominant hip. This forces an awkward compact swing with little room to attack back.Pickleball
Bogey GolfBeginner"Bogey golf" describes shooting roughly one over par on every hole. This means around 90 for an 18-hole, par-72 course. This means a common and respectable benchmark for a solidly developing recreational golfer.Golf
Bote ProntoIntermediateA bote pronto (Spanish for "quick bounce") is a half-volley taken immediately after the ball bounces, before it has risen appreciably. This means used when a fast, low ball at the feet leaves no time to let it climb to a comfortable contact height, common when defending a chiquita or handling a fast net exchange.Padel
Bottom HandIntermediateIn cricket batting, the bottom hand is the lower hand on the bat handle (for a right-hander, the right hand) and controls the power and direction of cross-bat strokes. This means too dominant, it closes the bat face and causes off-side trouble.Cricket
Bounce (Wedge)IntermediateBounce is the downward angle built into a wedge's sole, measured in degrees, that helps the club glide through sand or turf instead of digging in. This means higher bounce suits soft conditions and steep swings, lower bounce suits firm turf and shallow swings.Golf
BouncerIntermediateA bouncer is a fast, short-pitched delivery that rears up toward the batter's head or chest, used to intimidate, disrupt balance, and set up the fuller ball.Cricket
Bowed WristAdvancedA bowed wrist at the top of the backswing means the lead wrist flexes toward the palm (like a bow), closing the clubface and storing power for a powerful, face-controlled delivery.Golf
BowledBeginnerBowled is a dismissal where the ball, delivered by the bowler, hits the stumps and dislodges at least one bail without the batter touching it in a way that counts as a legal stroke.Cricket
BPF (Bat Performance Factor)AdvancedBPF (Bat Performance Factor) measures how much energy a bat's barrel returns to the ball compared with a perfectly rigid wall. This means a higher BPF means more trampoline effect and greater exit velocity from the same swing.Slow-Pitch Softball
Break PointBeginnerA break point is any point where the returning player, if won, would take the game away from the server. This means winning it "breaks" the server's serve.Tennis
Break Point Conversion RateAdvancedBreak point conversion rate is the percentage of break point opportunities a player actually wins, a key indicator of performance on the most pressure-heavy points in a match.Tennis
Breaking 100BeginnerBreaking 100 means finishing an 18-hole round in fewer than 100 total strokes. This means usually the first major scoring milestone a new golfer aims for. It depends far more on avoiding disaster holes than on hitting great shots.Golf
Breaking 80IntermediateBreaking 80 means finishing 18 holes in fewer than 80 strokes, a milestone typically associated with a single-digit handicap and generally requiring consistent ball-striking across every part of the game rather than one standout skill.Golf
Breaking 90BeginnerBreaking 90 means finishing 18 holes in fewer than 90 strokes, the milestone that typically separates a developing golfer from a genuinely competent one. It usually requires a reliable short game more than a longer drive.Golf
Bullpen Routine (Fast-Pitch)IntermediateA bullpen routine is a pitcher's structured warm-up and between-outing throwing sequence, building from short-distance arm circles to full-mound-distance pitches across her full pitch mix.Fast-Pitch Softball
Bullpen SessionBeginnerA bullpen session is a practice throwing session, typically off a mound. In which a pitcher works through their pitch mix at game-like intent without live hitters or the pressure of a real game situation.Baseball
Bump-and-RunBeginnerA bump-and-run is a low chip that uses the fringe and green to deliver the ball. This means bumped onto the surface just past the fringe and allowed to run to the hole like a putt.Golf
Bunker ShotIntermediateA bunker shot (sand shot) is played from a sand trap. Rather than striking the ball first, the club enters the sand behind the ball and the splash of sand carries it out.Golf
Bunt and RunIntermediateA bunt and run sends a baserunner on the pitch. At the same time, the batter is committed to bunting. This forces the defense to choose between fielding the bunt and covering the advancing runner.Fast-Pitch Softball
Bunt for a HitIntermediateA bunt for a hit is an offensive bunt where the hitter attempts to reach base rather than advance a runner. This means relying on perfect placement and speed rather than the batter's out being acceptable.Fast-Pitch Softball
Bunt PlacementBeginnerBunt placement is the deliberate choice of where to direct a bunt on the field. This means down a specific line, at a particular fielder, or into a soft spot. Instead of simply making contact.Fast-Pitch Softball
Bunt TechniqueBeginnerBunt technique is the fundamental skill of deadening the ball off the bat by absorbing its speed rather than swinging. This means using soft hands, a squared or angled stance. The bat as a cushion instead of a weapon.Baseball
Bunting MechanicsBeginnerBunting mechanics refer to the grip, stance, and bat-angle technique used to deaden a pitched ball and direct it to a specific area of the infield, whether for a sacrifice or a base hit.Fast-Pitch Softball
Called Strike RateAdvancedCalled strike rate is the percentage of pitches in the strike zone that a hitter takes for a strike rather than swinging at. This means the mirror image of chase rate, measuring missed opportunity rather than bad swings.Baseball
Called-Strike-Plus-Whiff Rate (CSW%)AdvancedCSW% is a pitching metric that combines called strikes and swinging strikes (whiffs) as a share of total pitches thrown, measuring how often a pitcher generates a strike without the ball being put in play.Baseball
Camera Angle GuidanceBeginnerCamera angle guidance is instruction on where to place the camera before filming a swing for analysis. This means typically down-the-line and face-on. Because the wrong angle can hide or distort exactly the information the analysis needs.Golf
Camera Angle QualityBeginnerCamera angle quality describes how well the recording position allows the system to see the relevant joints and movement plane. This means the single biggest controllable factor in analysis accuracy.Analysis Concepts
Camera-Based Launch MonitorIntermediateA camera-based launch monitor uses high-speed cameras and image processing to capture club and ball data from the fraction of a second around impact, rather than tracking the ball's full flight through the air.Golf
Carry (Illegal Hit)IntermediateA carry is an illegal hit where the ball is scooped, slung, or held on the paddle face for an extended moment rather than struck with a single, clean, distinct contact.Pickleball
Carry (Throw)IntermediateCarry describes how well a throw holds its velocity and straight-line trajectory through the air without tailing, sinking, or losing steam. This means a throw that "carries" arrives true to the target.Baseball
Carry DistanceBeginnerCarry distance is how far the ball travels through the air before it first lands — distinct from total distance, which includes roll.Golf
CastingIntermediateCasting is releasing the wrist angles too early in the downswing. This means like a fisherman throwing a line. This means which destroys lag, reduces speed, and adds loft at impact.Golf
Casting (Batting)IntermediateCasting is a swing fault where the hands and barrel swing out away from the body in a wide arc instead of taking a direct path to the ball. This means it kills bat speed and limits coverage of the inside pitch.Baseball
Casting from the TopIntermediateCasting from the top is when the wrists unload immediately at the start of the downswing. This comes from the very top of the backswing. This means before the lower body has had a chance to lead.Golf
Casting the BarrelIntermediateCasting the barrel is pushing the hands and bat head away from the body early in the swing. This creates a long, looping path that arrives late and loses rotational power.Slow-Pitch Softball
Catcher Throwing MechanicsIntermediateCatcher throwing mechanics encompass the footwork, transfer, and arm action a catcher uses to quickly and accurately throw to a base to retire a stolen-base attempt or catch a runner off base.Fast-Pitch Softball
Catcher-Pitcher CommunicationIntermediateCatcher-pitcher communication is the ongoing exchange of signals, mound visits. Shared read of the hitter that lets a battery agree on pitch selection and location before every pitch.Fast-Pitch Softball
Catcher's RoleBeginnerThe catcher's role in fast-pitch extends far beyond receiving pitches. This means they are the field general calling pitches, managing the pitcher's mindset, controlling the running game, and organizing the defense.Fast-Pitch Softball
Catcher's Setup TargetBeginnerA catcher's setup target is the glove position and location presented before the pitch to give the pitcher a clear, steady aiming point and communicate the intended location.Baseball
Catching PositionBeginnerA catching position in cricket is the stance and body alignment a fielder adopts. At the same time, waiting for a possible catch. This means soft knees, hands in front, eyes on the ball. This means to maximise reaction time and secure the catch.Cricket
CaughtBeginnerCaught is the most common dismissal in cricket. This means the batter is out when a fielder catches the ball on the full (without it bouncing) after it has come off the bat or glove.Cricket
Ceiling vs Floor (Scouting)IntermediateCeiling is a player's realistic best-case outcome if everything develops well. Floor is the realistic worst-case outcome if development stalls. This means scouts weigh both together, not just the exciting one.Baseball
Center of Gravity (Club)AdvancedA clubhead's center of gravity is the balance point manufacturers shift low and back to raise launch and reduce spin, or forward and low to promote a lower, more penetrating trajectory. This means a key design lever behind driver and iron performance.Golf
CenturyBeginnerA century is a batting milestone of 100 or more runs scored by a single batter in one innings. This means the most celebrated individual achievement in cricket batting.Cricket
Challenge System (Line Calls)IntermediateThe challenge system lets a player dispute a line call using electronic ball-tracking review, with a limited number of unsuccessful challenges allowed per set.Tennis
Change of SpeedsIntermediateChange of speeds is a pitching strategy of deliberately varying pitch velocity. This means not just pitch type. This means to disrupt a hitter's timing, most commonly by mixing a changeup in with a full-speed fastball or movement pitch.Fast-Pitch Softball
ChangeupIntermediateA changeup is an off-speed pitch thrown with the same windmill motion as the fastball but 10-20 mph slower, disrupting the hitter's timing. As a result, they commit early and swing ahead of the ball.Fast-Pitch Softball
Changeup (Pitching)IntermediateThe changeup is an off-speed pitch thrown with fastball arm speed but held deeper in the hand to reduce velocity by 8–15 mph, disrupting timing.Baseball
Charging a BloopIntermediateCharging a bloop is the technique of sprinting forward and low on a shallow, softly hit fly ball to make the catch at the shoetop or shoulder rather than waiting for the ball to fall in front of you.Slow-Pitch Softball
Charging a Ground BallBeginnerCharging a ground ball means running toward a slowly hit ball rather than waiting for it to arrive. This involves shortening the throw and taking away a bunt or slow roller before it becomes a hit.Baseball
Chase ContactAdvancedChase contact rate is the percentage of swings at pitches outside the strike zone that result in contact, measuring how well a hitter defends the plate even when they have made the decision to swing at a bad pitch.Baseball
Chase RateIntermediateChase rate is the percentage of pitches thrown outside the strike zone that a hitter swings at. This means a core plate-discipline metric where lower is almost always better.Baseball
Check SwingIntermediateA check swing is a hitter starting the swing motion and then stopping the bat before it crosses the plane of contact, most often to hold off on a pitch recognized late as a ball. This means its legality by the rulebook comes down to whether the bat and wrists broke toward the ball.Baseball
Check Swing (Slow-Pitch)BeginnerA check swing is when a hitter begins to commit to a pitch but stops or holds the bat before completing a full swing, usually reviewed by the umpire (or base umpire on appeal) to determine whether the bat crossed the plane of the plate or the wrists rolled over.Slow-Pitch Softball
Chicken WingIntermediateA chicken wing is the lead elbow bending and pointing away from the body through and after impact, instead of extending, usually a compensation for an out-to-in path or a blocked, stuck downswing.Golf
Chicken Wing Follow-ThroughBeginnerA chicken wing follow-through happens when the lead elbow pulls away from the body during the finish of a two-handed backhand, opening the racquet face early and cutting the swing short.Tennis
Chili-DipBeginnerA chili-dip is the most extreme version of a chunked chip. This means the club digs. As a result, far behind the ball on a very short finesse shot that the ball barely moves at all, sometimes traveling just a few inches.Golf
Chip ReturnIntermediateA chip return uses a short, compact slice motion to redirect a fast serve back low and controlled, prioritizing consistency over pace.Tennis
Chip SlapIntermediateA chip slap uses a short, quick adjustment step instead of a full crossover, letting a slapper stay compact and react late against fast pitching or off-speed pitches.Fast-Pitch Softball
Chip-and-RunBeginnerA chip-and-run is a low, bouncing chip that gets on the putting surface quickly and rolls toward the hole. This means the safest short-game choice when there is room between the ball and the green edge.Golf
ChippingBeginnerChipping is a short shot played from just off the green. This means a small swing that gets the ball rolling on the green quickly. This uses the putting surface to carry it to the hole.Golf
Chipping StanceBeginnerA good chipping stance narrows the feet, leans the shaft and weight slightly toward the target, and plays the ball back of center. This means a setup built for crisp, ball-first contact rather than the full-swing posture used for longer shots.Golf
ChiquitaIntermediateA chiquita (Spanish for "little one") is a soft, dipping ball hit from the back court toward the net opponents' feet. This forces them to volley up rather than down and neutralizing their dominant net position without risking a lob.Padel
Chiquita PlacementAdvancedChiquita placement is the deliberate targeting decision behind the shot. This means choosing the net player's weaker foot, a gap between two players, or a body-jamming line. Because a chiquita hit to the wrong spot simply gives an easy volley rather than the forced error it is meant to produce.Padel
Chiquita ReturnAdvancedThe chiquita return is the low, compact technique a net player uses to handle an opponent's chiquita. This means a ball arriving below the net cord at the feet. This means turning what should be a defensive scramble into a controlled, upward volley rather than a rushed error.Padel
Chopping Down on the BallBeginnerChopping down on the ball is an exaggerated, near-vertical bat path that hacks downward through contact rather than rotating on a plane, usually producing weak, high-bouncing ground balls.Slow-Pitch Softball
ChunkBeginnerA chunk (fat shot) is when the club strikes the ground before the ball. This means too early a low point. This means sending a short, low shot that often loses most of its distance.Golf
Chunked ChipBeginnerA chunked chip is a fat contact on a short finesse shot near the green. This applies where the club strikes the ground well before the ball, absorbing speed and leaving the shot sharply short of the target.Golf
Circle Change RecognitionIntermediateCircle change recognition is a hitter's ability to identify a circle changeup out of the pitcher's hand or early flight. As a result, she can hold her swing rather than lunging in front of the slower pitch.Fast-Pitch Softball
Circle Changeup GripIntermediateThe circle changeup grip forms a circle with the thumb and index finger against the side of the ball, letting the remaining three fingers do the work. This means a grip designed to reduce velocity without changing arm speed.Baseball
Claw Grip (Putting)IntermediateThe claw grip separates the trail hand from the lead hand on the putter, holding the handle more like a pencil against the palm than wrapped around it. This means a popular fix for excess trail-hand wrist action and the putting yips.Golf
Closed StanceBeginnerA closed stance aligns the feet, hips, and shoulders right of the target line (for a right-hander), a setup sometimes used deliberately to hit a draw but more often an unintentional cause of a push or hook.Golf
Closed StanceBeginnerA closed stance positions the front foot across the body at contact, promoting a natural weight transfer from back to front and simplifying the swing path for beginners.Tennis
Closed-Stance BackhandIntermediateA closed-stance backhand steps the front foot across toward the net before contact. This allows a full weight transfer forward into the shot at the cost of slightly slower recovery.Tennis
Club FittingIntermediateClub fitting is a launch-monitor-based process that matches shaft, length, lie angle, loft, and head design to an individual golfer's swing, rather than relying on stock, off-the-rack specifications built for an average golfer.Golf
Club LengthIntermediateClub length is fitted to a golfer's height, arm length, and posture at address. This means a mismatched length changes lie angle at impact and forces compensations that can undermine consistency more than most golfers realize.Golf
Club PathAdvancedClub path is the horizontal direction the clubhead is moving through impact, relative to the target line, in degrees. Positive is in-to-out (a draw bias); negative is out-to-in (a fade or slice bias).Golf
Club SelectionBeginnerClub selection is choosing the right club for each shot based on real carry distance, lie, wind, elevation, and hazard placement. This means one of the highest-impact decisions in scoring.Golf
Club SpeedIntermediateClub speed is how fast the clubhead is moving just before impact, in mph. It sets the ceiling for ball speed and distance — but only if contact is clean.Golf
Coachability (Intangibles)BeginnerCoachability is a player's willingness and ability to receive feedback, apply it without defensiveness, and adjust behavior or mechanics based on instruction. This means one of the "intangible" traits scouts and coaches weigh alongside physical tools.Baseball
Coed Rules (Modified Slow-Pitch)BeginnerCoed rules adapt slow-pitch softball for mixed-gender rosters. They often cover batting order, lineup balance, and who may field certain balls.Slow-Pitch Softball
Cold ShankAdvancedA cold shank is a shank that appears without warning in an otherwise solid ball-striking session. It is caused by contact on the hosel rather than the face. This sends the ball sharply right at a steep angle.Golf
Collapsing Back SideAdvancedCollapsing the back side is a fault where the back knee and hip drop and buckle inward during the swing rather than staying stacked over the back foot, robbing the swing of ground force and forcing the arms to finish the job alone.Baseball
Collapsing the Back SideIntermediateCollapsing the back side is when the back knee and hip drop and cave inward during the swing rather than staying stacked and rotating, draining rotational power and lowering the swing plane unpredictably.Slow-Pitch Softball
College Recruiting TimelineAdvancedThe college recruiting timeline is the general sequence of contact rules, communication windows, and decision points that shape when and how college coaches can engage with a fast-pitch softball prospect.Fast-Pitch Softball
Command vs. ControlIntermediateControl means throwing enough strikes to avoid walks; command means locating a pitch to a precise spot within the zone. A pitcher can have one without the other.Baseball
Common Beginner Mistake: Overhitting DinksBeginnerNew players often swing at dinks with too much paddle speed, popping the ball up above net height and handing the opponent an easy attacking shot instead of keeping it low and soft.Pickleball
Common Beginner Mistake: Poor Court CoverageBeginnerNew doubles teams often leave gaps in court coverage. This means both players chasing the same ball, standing too close together, or failing to shift as a unit. This means. This is because they have not yet learned to move together as a formation.Pickleball
Common Beginner Mistake: Standing in the KitchenBeginnerA frequent beginner habit is resting inside the non-volley zone between shots rather than only stepping in to play a bounced ball and retreating back to the line immediately after.Pickleball
Common Beginner Mistake: Volleying Too EarlyBeginnerNew players frequently try to volley the serve or the return of serve before both have legally bounced once. This is a fault under the two-bounce rule.Pickleball
Common Beginner Swing FaultsBeginnerThe handful of misses nearly every beginner experiences. This means topped shots, chunked shots, slices, and shanks. This means almost all trace back to a small set of setup and contact issues rather than dozens of unrelated problems.Golf
Compact BackswingBeginnerA compact backswing is a short, controlled preparation where the paddle is drawn back only as far as needed. This means typically to hip level. This means before the forward swing. This reduces reaction time and improving consistency.Pickleball
Compact Swing TimingIntermediateCompact swing timing describes a short, direct path from load to contact that minimizes the time between triggering the swing and the bat reaching the ball. This gives a hitter more margin for error against fast-pitch's short reaction window.Fast-Pitch Softball
Compensation PatternAdvancedA compensation pattern is a movement the body adds, usually unconsciously, to offset an earlier fault and still make contact with the ball. This means it often becomes a habit in its own right, layered on top of the original problem.Golf
Compression RatingIntermediateCompression rating measures how much force it takes to compress a softball one-quarter inch, in pounds. Higher compression means a harder ball that rebounds faster off the bat — and typically travels farther on well-struck contact.Slow-Pitch Softball
Confidence ScoreBeginnerA confidence score is a 0–100 calibration of how much to trust a finding, scaled by sample size, shot-to-shot consistency, and how complete your inputs were.Analysis Concepts
ConnectionIntermediateConnection is keeping the arms and body moving together during the swing. As a result, the arms never get ahead of or behind the body's rotation, maintaining a consistent arc and face delivery.Golf
Consistency ScoreIntermediateA consistency score measures how tightly grouped your metrics are across multiple swings. This means low variance produces a high score. This is. This is because consistency is often more valuable than peak performance.Analysis Concepts
Contact PointBeginnerContact point is where on the paddle face, and where in space relative to the body, the ball meets the paddle. This means the single biggest controllable variable in producing consistent shots.Pickleball
Contact PointIntermediateContact Point in padel is the position in space. This means relative to the body and racket face. This means where the ball and the racket face meet at impact, and is the single most important determinant of shot quality, direction, and consistency.Padel
Contact PointBeginnerThe contact point is where the bat meets the ball relative to your body. In slow pitch it sits out in front of the plate, letting the barrel travel slightly upward to match the ball's descending arc rather than hitting under or over it.Slow-Pitch Softball
Contact PointIntermediateThe contact point is the specific location in front of (or at) the plate where the bat meets the ball. This means which varies by pitch location, pitch type, and desired ball-flight direction.Fast-Pitch Softball
Contact Point (Batting)IntermediateContact point is where in space, relative to the hitter's body and the plate, the bat meets the ball. This means it shifts predictably by pitch location. A contact point that doesn't shift with location is a common source of weak contact.Baseball
Contact Point DriftIntermediateContact point drift describes an uneven contact location from swing to swing. This means sometimes in front, sometimes late, sometimes too close to the body. This means that produces hard to predict results even with a repeatable swing shape.Tennis
Continental GripBeginnerThe continental grip positions the base knuckle of the index finger on bevel 2 of the handle, the universal grip for volleys, serves, overheads, slices, and drop shots.Tennis
Continental GripBeginnerThe Continental Grip is the most versatile grip in padel. This means and the recommended default. This means allowing players to hit forehands, backhands, volleys, and serves without changing grip between shots.Padel
ContraparedAdvancedA contrapared (Spanish for "against the wall") is a last-resort defensive shot in which the player deliberately hits the ball into their own glass. This means usually the back glass. This means hard enough that the rebound itself carries it back over the net into the opponents' court.Padel
Contrapared SetupAdvancedContrapared setup is the anticipatory footwork and positioning that happens before the ball ever touches the side glass. This means moving toward the projected rebound zone based on the incoming ball's speed and spin. Because waiting until contact to react leaves no time to play the shot cleanly.Padel
COR (Coefficient of Restitution)AdvancedCOR (Coefficient of Restitution) measures how much of a ball's impact energy is returned as rebound energy. A 0.52 COR ball rebounds at 52% of its incoming speed off a rigid surface. This means the higher the COR, the livelier and farther the ball flies.Slow-Pitch Softball
Core Rotation in StrokesIntermediateCore rotation is the turning of the torso between the hips and shoulders during a stroke, transferring energy from leg drive and hip rotation up into the arm and racquet.Tennis
Corner Infield PlaysIntermediateCorner infield plays are the defensive assignments and positioning of the first and third basemen when the short game is in play. This means charging bunts, reading the hitter's slap, and executing the correct throw to the right base.Fast-Pitch Softball
Count AdvantageIntermediateCount advantage describes who the current ball-strike count favors. This means the pitcher (with two strikes or ahead) or the hitter (with three balls or behind). This means and how both sides should adjust their approach accordingly.Fast-Pitch Softball
Counter AttackAdvancedA counter attack is a controlled offensive response to an opponent's speed-up or flick, redirecting their pace back at them before they can reset.Pickleball
Counter Speed-UpAdvancedA counter speed-up is an immediate return of pace on an opponent's speed-up attempt. This involves redirecting their own attacking shot back with equal or greater speed rather than blocking it.Pickleball
Counter-Punching StyleIntermediateCounter-punching is a defensive-minded style that absorbs an opponent's pace, redirects it back with consistency and depth, and waits patiently for the opponent to make the error.Tennis
Course Handicap vs Handicap IndexBeginnerHandicap Index is a portable number representing a golfer's general ability, calculated from past scores. Course handicap converts that same index into the actual number of strokes they receive on a specific course and tee. This uses that course's slope rating.Golf
Course ManagementIntermediateCourse management is the decision-making strategy for where to aim. This club to use, and how to play each hole to minimize risk and score effectively relative to your skills.Golf
Course Rating vs Slope RatingIntermediateCourse rating estimates the score a scratch golfer would shoot on a course. At the same time, slope rating measures how much harder that same course plays for a bogey golfer relative to a scratch golfer. This means together they adjust a handicap for the specific course being played.Golf
Court EnclosureBeginnerThe Court Enclosure is the full perimeter structure of a padel court. This means glass walls at the back and sides, metal fencing above and at certain sections. This means which defines the unique enclosed environment that makes wall play possible.Padel
Court PositioningIntermediateCourt positioning is where a player stands between shots, continuously adjusted to maximize coverage of the opponent's most likely replies while minimizing defensive vulnerability.Tennis
Court PositioningBeginnerCourt positioning is the ongoing management of where you stand relative to the net, your partner. The ball. This means the foundation of all tactical decision-making in pickleball.Pickleball
Court ZonesBeginnerCourt Zones in padel refer to the three main areas of each half-court. This means the net zone, the midcourt. The back zone. This means each demanding different shot selections and positioning rules.Padel
Courtesy RunnerBeginnerA courtesy runner is a substitute allowed to run the bases for a player who reaches base but is unable to run. This means commonly for injury, age-based recreational-league eligibility, or a pitcher/catcher who needs rest between innings. Without that player leaving the game.Slow-Pitch Softball
Cover DriveIntermediateThe cover drive is an elegant front-foot stroke that sends a full ball outside off stump through the cover region, between point and mid-off.Cricket
Cover PlayIntermediateCover Play refers to one partner temporarily taking responsibility for more than their half of the court to protect the gap left when the other partner is displaced, stretched, or out of position.Padel
CreaseBeginnerThe crease is any of the white painted lines on the cricket pitch that define legal bowling positions, the safe zone for batters. The starting point for LBW and run-out adjudications.Cricket
Cross-Court DinkIntermediateA cross-court dink is a soft shot hit diagonally over the lowest, widest part of the net. This gives the dinker the largest margin for error and the best angle to pull an opponent off the court.Pickleball
Cross-Handed Grip (Putting)IntermediateA cross-handed (left-hand-low) putting grip reverses the standard hand order. As a result, the lead hand sits below the trail hand on the handle. This means a common fix for golfers whose trail hand dominates and breaks down the lead wrist through impact.Golf
Cross-Step RecoveryIntermediateCross-step recovery uses a crossover stride. This means one foot crossing in front of or behind the other. This means to cover ground quickly when returning to a base position after a wide shot.Tennis
CrosscourtBeginnerA Crosscourt shot in padel travels diagonally across the net to the opposite side of the court. This means the longest available shot path, offering the most margin over the net and the widest angle.Padel
Crosscourt ShotBeginnerA crosscourt shot travels diagonally across the net to the opposite side of the court, exploiting the longest available distance and the lowest part of the net.Tennis
Crossover Slap StepIntermediateThe crossover slap step is a footwork pattern where a slapper crosses her back foot in front of her front foot to begin moving toward the pitcher before swinging, generating momentum into contact.Fast-Pitch Softball
Crossover StepIntermediateThe crossover step is the explosive first step after the split step, where the foot on the side away from the ball crosses in front of the body to generate maximum lateral acceleration.Tennis
Crossover StepIntermediateA crossover step is a running movement where one foot crosses in front of the other to cover wide balls quickly, sacrificing momentary net-facing to reach balls the shuffle step cannot.Pickleball
Crow HopIntermediateA crow hop is an illegal pitching motion in which the pitcher replants the pivot foot after the initial push-off, effectively relaunching and gaining an unfair advantage in distance or momentum.Fast-Pitch Softball
Crow Hop (Throwing)BeginnerA crow hop is a small skip-step a fielder uses after fielding a ball. This means replanting the back foot and shuffling toward the target. This means to gather momentum and align the body before a long or off-balance throw.Baseball
Cupped WristAdvancedA cupped wrist at the top of the backswing means the lead wrist bends backward (away from the palm), opening the clubface and commonly contributing to slices or weak fades.Golf
Curve Ball FlightBeginnerA curve ball flight is any shot that bends noticeably left or right in the air, produced whenever the clubface angle and swing path differ enough at impact to tilt the ball's spin axis away from horizontal.Golf
CurveballIntermediateThe curveball is an off-speed breaking pitch with topspin that makes it arc downward, often sharply, as it crosses the plate.Baseball
Curveball – Fast-PitchIntermediateA curveball is a fast-pitch pitch thrown with lateral spin that causes the ball to break sharply to one side as it reaches the plate, disrupting a hitter's timing and eye-line.Fast-Pitch Softball
Curveball Spin DirectionAdvancedCurveball spin direction refers to the roughly vertical spin axis, tilted toward horizontal, that makes a fast-pitch curveball break sideways away from a same-handed hitter rather than up or down.Fast-Pitch Softball
Cut FastballAdvancedThe cutter is a fastball with late glove-side movement — harder than a slider, smaller break than a slider — that jams or cuts away from hitters.Baseball
Cutoff AlignmentIntermediateCutoff alignment is the positioning of an infielder in a direct line between an outfielder's throw and the target base, ready to intercept and redirect the throw if needed.Slow-Pitch Softball
Cutoff ManBeginnerThe cutoff man is the infielder who positions in a direct line between an outfielder and the base being defended, ready to intercept. This means or "cut". This means the throw and redirect it if the original target is no longer the best play.Baseball
Cutoff PlayIntermediateA cutoff play routes an outfield throw through an infielder (the cutoff man) positioned between the outfielder and home plate. This allows the defense to redirect throws or boost accuracy over long distances.Slow-Pitch Softball
D-PlaneAdvancedThe D-Plane is the modern model explaining that a ball's initial direction is determined mostly by face angle (not path). At the same time, path relative to face determines the curve. This means replacing the older, oversimplified "path starts it, face curves it" idea.Golf
Data Overload (Too Many Metrics)BeginnerData overload happens when a golfer is shown. As a result, many numbers from a launch monitor or video analysis at once that no single one gets acted on. This means more information without clear prioritization can leave a golfer more confused, not less.Golf
Data Source LabelBeginnerA Data Source Label is the badge shown alongside every metric in SwingVantage that identifies where that data came from. This means Measured, Estimated, AI Interpreted, Placeholder, or Real. This means. As a result, you always know how to weight it.Analysis Concepts
Dead Dink (No-Bounce Slow Roll)AdvancedA dead dink is a dink hit with. As a result, little forward momentum that it barely clears the net and dies almost immediately on the bounce, denying the opponent any rhythm or pace to work with.Pickleball
Death OversBeginnerThe death overs are the final overs of a limited-overs innings. This means typically overs 17–20 in T20 or 41–50 in one-day cricket. This means when batting teams try to maximise runs and bowlers aim to minimise them.Cricket
Death-Overs BowlingAdvancedDeath-overs bowling is the skill of bowling the final overs of a limited-overs innings. This means typically overs 17–20 in T20 or overs 41–50 in one-day cricket. This means when the batting team is trying to hit every ball for a boundary.Cricket
DecelerationIntermediateDeceleration is when the club slows down through the impact zone instead of accelerating past the ball. This means a common cause of mishits on chips, pitches, and bunker shots.Golf
Deep DivotIntermediateA deep divot is an unusually thick chunk of turf taken on an iron shot. This indicates a steep angle of attack or a low point positioned too far behind the ball, both of which cost distance and consistency.Golf
Deep ServeBeginnerA deep serve is a serve that lands close to or near the baseline of the opponent's service box. This forces the returner farther from the kitchen line and giving the serving team more time to advance.Pickleball
Defensive Back PositionBeginnerThe Defensive Back Position is where a pair retreats when they have lost net control. This means playing from behind the service line near the back glass, focusing on lobbing quality and glass reading until they can regain the net.Padel
Defensive LobBeginnerA Defensive Lob is a high, flat or slightly underspin lob hit from a difficult position to reset the point and force opponents away from the net, prioritising height and depth over power or spin.Padel
Defensive PositioningIntermediateDefensive positioning is the pre-pitch alignment of all fielders based on the current hitter's tendencies, the game situation, the count, and the score.Slow-Pitch Softball
Defensive RangeIntermediateDefensive range is how much ground a fielder can cover and convert into outs — a combination of first step, speed, reads, and athleticism.Baseball
Defensive ShiftAdvancedA defensive shift is an unconventional repositioning of fielders toward one side of the field to take away a pull hitter's most likely batted-ball zone.Slow-Pitch Softball
Defensive SliceIntermediateA defensive slice uses underspin to keep the ball low and floating with minimal effort, letting an out-of-position player buy time and stay in the point rather than attempt a full topspin shot.Tennis
Defensive VersatilityAdvancedDefensive versatility is a player's demonstrated ability to field multiple positions competently. This increases her value to a team by filling depth needs across the roster rather than a single spot.Fast-Pitch Softball
Defensive Wall ReturnIntermediateA defensive wall return is any shot played after letting a ball rebound off the back or side glass instead of trying to intercept it before the bounce. This means the single habit that turns padel's walls from a spectator novelty into the sport's core defensive safety net.Padel
Deliberate PracticeAdvancedDeliberate practice is structured, focused improvement work with specific targets, immediate feedback, and repeated challenge at the edge of current ability. This means distinct from casual hitting or playing rounds.Golf
Deliberate PracticeIntermediateDeliberate practice is focused, feedback-rich work on a specific, diagnosed weakness. This means distinct from mere repetition or play. This means that produces faster skill gains per hour of effort.Analysis Concepts
Delivery PositionAdvancedDelivery position describes where the club shaft and clubface point relative to the body and target line in the final moments before impact. This means the checkpoint coaches and video analysis use to predict where a shot is headed before it is actually struck.Golf
Descending BlowIntermediateA descending blow is contact made. At the same time, the club is still moving downward relative to the ground, the standard, correct angle of attack for iron and wedge shots struck off the turf.Golf
Deterministic IntelligenceBeginnerDeterministic intelligence is analysis that follows explicit, written rules, so the same inputs always produce the same answer and you can trace exactly why.Analysis Concepts
Deuce and AdvantageBeginnerDeuce is a tied score of 40-40 in a game, after which a player must win two points in a row. This means first reaching advantage, then winning the next point. This means to win the game.Tennis
Diagnostic ConfidenceBeginnerDiagnostic confidence is how certain SwingVantage is about a given finding, based on how much data was available and how reliably the pattern appears.Analysis Concepts
Diagonal PlayIntermediateDiagonal Play is the tactical principle of directing most exchanges crosscourt. This means along the diagonal. This means to maximise margin, create angles, and keep the point in a stable crosscourt pattern until an opportunity to go parallel arises.Padel
DinkBeginnerA dink is a soft, controlled shot hit from near the kitchen line that arcs just over the net and lands in the opponent's kitchen. This forces them to hit upward and preventing an aggressive return.Pickleball
Dink Rally PatienceIntermediateDink rally patience is the discipline to keep the ball low and controlled through an extended dink exchange rather than forcing an early attack, waiting for a genuine opportunity instead of manufacturing one.Pickleball
Dink Target (Feet vs Body)IntermediateDink targeting is the choice between aiming a dink at an opponent's feet. This forces an awkward low contact, versus their body. This crowds their paddle and limits a clean swing.Pickleball
Dinking AngleIntermediateDinking angle refers to the direction and sharpness of a dink relative to the net. This determines how much lateral court an opponent must cover to reach the next shot.Pickleball
Direct Hit Run-OutIntermediateA direct hit run-out is when a fielder throws the ball and hits the stumps directly. Without the ball being relayed through the wicket-keeper. This means to dismiss a batter who is short of their crease.Cricket
DispersionAdvancedDispersion is how spread out your shots are, plotted as a pattern. A tight dispersion means repeatable contact; a wide one signals uneven results in face, path, or strike.Golf
Distance ControlIntermediateDistance control is calibrating how far the ball travels. This means in putting by swing length and tempo, in the short game by carry distance. This means. As a result, the ball ends up close to its target.Golf
Diving Catch TechniqueAdvancedDiving catch technique is the mechanics of extending the body fully. This is parallel to the ground and glove-first, to catch a ball just beyond a fielder's normal running range. This means a last-resort option, not a first choice.Baseball
Diving StopIntermediateA diving stop is a fielding technique where the player launches themselves horizontally through the air to stop a ball that is beyond their standing reach, often preventing a certain boundary.Cricket
DivotIntermediateA divot is the strip of turf taken after impact with an iron. Its location and direction reveal your low point and club path — a free, visible feedback tool.Golf
Doppler Radar TrackingAdvancedDoppler radar tracking measures a golf shot by bouncing radio waves off the ball and club in flight and reading the frequency shift, calculating speed, spin, and trajectory from actual flight data rather than a single frozen frame.Golf
Double Bogey and Blow-Up HolesBeginnerA double bogey is two strokes over par on a hole. A "blow-up hole" is the more casual term for any hole that goes much worse than that, and learning to limit blow-up holes is usually the single biggest lever a beginner has for lowering their score.Golf
Double FaultBeginnerA double fault occurs when both the first and second serve land outside the service box, awarding the point directly to the returner.Tennis
Double Hit FaultIntermediateA double hit fault occurs when a player makes two clearly separate hitting motions at the ball in the same point of contact. This means an unintentional double touch within one continuous stroke is generally treated differently and is not on its own a fault.Pickleball
Double PlayIntermediateA double play retires two base runners on the same batted ball. This is most commonly on a ground ball through the infield with a runner on first.Slow-Pitch Softball
Double Play PivotIntermediateThe double play pivot is the footwork a middle infielder uses at second base to receive a throw, redirect toward first base, and release a throw quickly. This means all. At the same time, avoiding contact with a sliding baserunner.Baseball
Double Play Turn (Slow-Pitch)AdvancedThe double play turn is the pivot footwork a middle infielder uses at second base to receive a throw. The fielder must touch the bag, and release a throw to first in one continuous motion. At the same time, avoiding contact with the sliding runner.Slow-Pitch Softball
Double-Bend BackhandAdvancedA double-bend backhand keeps both elbows bent through contact on a two-handed backhand, a compact arm structure associated with elite ball-striking and disguise.Tennis
Double-HitBeginnerA double-hit occurs when the clubhead contacts the ball a second time during the same swing, most common on slow, decelerating chips and pitches near the green, and counts as an extra stroke under the rules.Golf
Double-Wall BatAdvancedA double-wall bat has two concentric layers of barrel material that flex together at contact to produce greater trampoline effect. This means returning more energy to the ball and increasing exit velocity compared with a single-wall design.Slow-Pitch Softball
Doubles Communication CallsBeginnerDoubles Communication Calls are the short, pre-agreed words a padel pair uses in the moment. This means like "mine," "yours," "switch," or "lob". This means to resolve who takes a shot and coordinate movement without stopping to think during a fast exchange.Padel
Doubles PositioningBeginnerDoubles positioning is how two partners divide and cover the wider doubles court, typically one player at net and one at the baseline. This shifts together as the point develops.Tennis
Doubles RotationIntermediateDoubles Rotation in padel describes the coordinated lateral and forward-backward movement of a pair as a unit to maintain court coverage, close gaps, and respond to each ball without either player being left exposed.Padel
Down-and-In Swing PathIntermediateA down-and-in swing path is a barrel that descends and cuts across toward the hitter's body through the zone, instead of staying on the pitch's plane. This means producing weak pull-side grounders and easy outs on the top hand.Baseball
Down-and-In Swing Path (Slow-Pitch)AdvancedA down-and-in swing path brings the barrel into the hitting zone from slightly above and outside the ball before flattening through contact, a path advanced slow-pitch hitters use to cover the whole plate and drive the ball to all fields.Slow-Pitch Softball
Down-the-Line DinkIntermediateA down-the-line dink is a soft shot hit straight ahead rather than diagonally. It is aimed at the opponent directly across the net instead of the cross-court player.Pickleball
Down-the-Line Passing ShotAdvancedA down-the-line passing shot is hit parallel to the sideline past a net player, using the shortest, straightest path and often the element of surprise.Tennis
Down-the-Line ShotIntermediateA down-the-line shot travels parallel to the nearest sideline, changing the direction of a crosscourt rally to create a sharper angle or exploit an open court.Tennis
Down-the-Line ViewBeginnerThe down-the-line view films the swing from directly behind the golfer along the target line. It is the best angle for reading swing plane, club path, and delivery position.Golf
Down-the-Middle AttackIntermediateA down-the-middle attack is a hard, fast shot aimed between two opponents in doubles, targeting the lowest part of the net and forcing a "yours-or-mine" decision under pressure.Pickleball
Drag BuntAdvancedA drag bunt is a bunt initiated. At the same time, already moving toward first base. This means typically by a left-handed hitter using their momentum out of the box. This means designed to beat out a hit rather than sacrifice an out.Baseball
Drag BuntIntermediateA drag bunt is a bunt for a base hit where a fast runner. This means typically a left-handed slapper. This means starts moving toward first before contact. This uses the running start to beat the throw.Fast-Pitch Softball
DrawBeginnerA draw is a controlled shot that curves gently from right to left for a right-handed golfer (the opposite for a lefty). It is produced by a clubface slightly closed to the swing path but still open to the target line.Golf
Draw BiasIntermediateA draw bias is a golfer's repeatable tendency to curve shots right-to-left (for a right-hander), whether by natural swing pattern. A related detail is a deliberate stock shot, or equipment setup, as opposed to a golfer who tends to fade or hit it straight.Golf
Drill ProgressionIntermediateA drill progression is an ordered sequence of practice exercises that move from isolated, slow, and controlled movements toward full-speed, contextual performance. This means matching how motor learning actually works.Analysis Concepts
DriveBeginnerA drive is a hard, flat or low-trajectory shot hit from mid-court or the baseline, intended to push opponents back or force a weak return.Pickleball
DriveBeginnerIn cricket, a drive is an attacking stroke played with a straight, full swing of the bat to a full-length ball. This sends it along the ground in front of the wicket. (This differs entirely from a golf drive off the tee.)Cricket
Drive ServeIntermediateA drive serve is a hard, flat or low-trajectory serve intended to prevent the returner from taking an aggressive position and returning with pace.Pickleball
Driver LoftIntermediateDriver loft is the angle stamped on the club face — typically 8–12° for tour players, higher for moderate swing speeds. The correct loft maximizes carry by delivering the optimal launch-spin combination.Golf
Drop BallIntermediateA drop ball is a fast-pitch pitch thrown with topspin that causes it to dive sharply as it nears the plate, inducing ground balls and swings over the top of the ball.Fast-Pitch Softball
Drop ProcedureIntermediateThe modern drop procedure requires releasing the ball from knee height, straight down, within the defined relief area. This means a simpler process than the older shoulder-height drop. But one still commonly done incorrectly.Golf
Drop ShotIntermediateA drop shot is a softly struck groundstroke or volley designed to land just over the net with minimal forward bounce, drawing the opponent in from the baseline and winning the point through touch.Tennis
Drop ShotIntermediateA drop shot is a softly hit ball that barely clears the net and dies in the opponent's kitchen, drawing them forward and opening the court behind them.Pickleball
Drop ShotAdvancedA Drop Shot in padel is a softly struck, low-bouncing shot designed to fall just over the net and die before reaching the back glass, pulling opponents in and disrupting their defensive positioning.Padel
Drop Shot DisguiseAdvancedDrop shot disguise is keeping the racquet preparation and body position identical to a normal groundstroke until the last moment. As a result, the opponent commits to defending a deep ball.Tennis
Drop Step (Outfield)IntermediateA drop step is an outfielder's first movement on a ball hit over their head or into a gap. This means a quick pivot of the back foot that opens the hips and puts the fielder on the most direct running angle, rather than a false first step forward.Baseball
Drop Step (Pitching Wind-Up)IntermediateThe drop step is a wind-up style in which the pitcher steps back and slightly to the side with the non-pivot foot before driving forward. This uses the extra backward motion to build additional momentum toward the plate.Fast-Pitch Softball
Drop VolleyAdvancedA drop volley absorbs the pace of an incoming ball at the net, redirecting it with backspin. As a result, it barely clears the net and dies close to it. This means an extreme touch shot that exploits an opponent deep in the court.Tennis
Dropping the Back ShoulderIntermediateDropping the back shoulder is a fault where the rear shoulder tilts down toward the ground during the swing, steepening the bat path and often the root mechanical cause behind an uppercut and pop-ups.Baseball
Duck HookAdvancedA duck hook is a low, hard, sudden left-diving shot caused by a closed clubface relative to a steep, out-to-in or excessively in-to-out path at impact, often with an active release and a flip of the hands.Golf
Dynamic LoftAdvancedDynamic loft is the actual loft presented by the face at impact — not the loft stamped on the club. It is the main driver of how high the ball launches.Golf
Early Commitment (Timing)IntermediateEarly commitment is deciding to swing. This means and beginning irreversible swing mechanics. This means before the pitch's location, height, and speed are actually confirmed, often based on a guess rather than a read.Slow-Pitch Softball
Early Contact (Slow-Pitch)IntermediateEarly contact happens when the bat meets the ball well in front of the ideal contact point, usually pulling the ball weakly or missing it entirely. This is because the swing has already started decelerating.Slow-Pitch Softball
Early Contact / Rushing the ShotBeginnerRushing the shot means starting the forward swing before the body has finished loading. This forces contact too early and too far in front of a stable base.Tennis
Early ExtensionAdvancedEarly extension is thrusting the hips toward the ball during the downswing. This causes the golfer to stand up out of posture and forces compensations at impact.Golf
Early ReleaseIntermediateAn early release is when the wrists unhinge and the forearms fire before the hands reach the hitting zone, costing lag, speed, and compression.Golf
Early Swing TriggerBeginnerAn early swing trigger is a timing mistake in which the hitter commits to the swing before the ball has left the pitcher's hand. This usually resulting in weak contact out in front of the plate or a complete miss on any pitch with late movement.Fast-Pitch Softball
Eastern GripBeginnerThe eastern grip places the base knuckle of the index finger on the flat side bevel of the handle (bevel 3). This allows a flat or moderate-topspin forehand with a comfortable contact height.Tennis
Eephus PitchAdvancedThe eephus is a very slow, high-arcing pitch thrown with minimal arm speed. This means often 30-40 mph slower than a fastball. This means designed purely to disrupt a hitter's timing with an extreme change of pace.Baseball
Effective VelocityAdvancedEffective velocity is the idea that a pitch's perceived speed to a hitter depends on its location. This means inside pitches feel faster, outside and low pitches feel slower. This means not just its radar-gun reading.Baseball
End LoadIntermediateEnd load is extra weight concentrated toward the barrel end of a bat, increasing swing momentum and exit velocity on squared-up contact. End-loaded bats only deliver their benefit when the hitter generates enough bat speed to keep their swing on time.Slow-Pitch Softball
ErneAdvancedAn Erne is an aggressive shot where a player jumps or runs around the outside of the kitchen to volley a ball beside the net post, legally contacting it outside the non-volley zone for an unexpected, sharp-angled winner.Pickleball
Erne SetupAdvancedThe erne setup is the positioning and read a player makes before jumping around or through the kitchen to volley a ball outside the sideline, without stepping through the kitchen itself.Pickleball
Estimated ValueBeginnerAn estimated value is a number derived from observable cues and encoded rules rather than from direct sensor measurement. This means a confident, grounded inference that is never presented as a measured fact.Analysis Concepts
Evidence LabelBeginnerAn evidence label separates what SwingVantage measured (a sensor or launch-monitor number) from what it estimated (an inferred likely pattern). As a result, an estimate is never presented as a lab measurement.Analysis Concepts
Exit Speed (Slow-Pitch)IntermediateExit speed is how fast the ball travels immediately after leaving the bat, driven by bat speed, contact-point quality. The bat's certified performance rating within legal limits.Slow-Pitch Softball
Exit Velocity (EV)IntermediateExit velocity is how fast the ball comes off the bat, in mph. It is a ceiling metric — the harder you hit it, the farther it can go.Baseball
Explosion ShotIntermediateAn explosion shot (also called a splash shot) is a standard greenside bunker shot named for the visible spray of sand the club displaces as it slides underneath the ball, lifting it out without direct clubface contact.Golf
Extension at ContactIntermediateExtension means the arms extend through and just beyond contact rather than collapsing into the body. This means at contact itself the rear arm usually keeps some bend, especially on inside pitches, with extension completing just after impact.Baseball
Extension at ContactIntermediateExtension at contact is the point in the swing where the arms reach near-full length through the contact zone, transferring maximum energy from the kinetic chain into the ball.Fast-Pitch Softball
Extension Through ContactIntermediateExtension through contact is the full straightening of the arms through the hitting zone. This allows the barrel to stay on the ball's path as long as possible and maximize energy transfer.Slow-Pitch Softball
Extra Player (EP) RuleBeginnerThe extra player (EP) rule allows a slow-pitch team to add one or more additional hitters to the batting lineup beyond the number of defensive positions, letting more rostered players bat. At the same time, only ten (or the league's standard number) take the field on defense at a time.Slow-Pitch Softball
Face AngleAdvancedFace angle is where the clubface points at impact, relative to the target line, in degrees. It determines roughly 75–85% of the ball's starting direction.Golf
Face-Balanced PutterIntermediateA face-balanced putter has its head weighted. As a result, the face points straight up when the shaft is balanced on a finger. This means a design that resists twisting during a straighter-back-and-through stroke and is common in mallet putters.Golf
Face-On ViewBeginnerThe face-on view films the swing from directly in front of the golfer. It is the best angle for reading hip and shoulder rotation, weight transfer, spine tilt, and early extension.Golf
Face-to-PathProFace-to-path is the difference between face angle and club path at impact. It is the single number that determines how much, and which way, the ball curves.Golf
FadeBeginnerA fade is a controlled shot that curves gently from left to right for a right-handed golfer. It is the playable version of a slice, produced by a face slightly open to the swing path.Golf
Fade BiasIntermediateA fade bias is a golfer's repeatable tendency to curve shots left-to-right (for a right-hander). This many better players prefer for its consistency and control even though it typically sacrifices some distance compared to a draw.Golf
Fairway Bunker TechniqueIntermediateFairway bunker technique prioritizes clean ball-first contact over distance. This uses a slightly narrower stance, a more level swing, and often one club more than a comparable fairway shot to make up for choked-down grip and reduced swing speed.Golf
Fairway WoodBeginnerA fairway wood is a lower-lofted, larger-headed club (commonly a 3-, 5-, or 7-wood) designed to be hit off the turf as well as a tee, covering long-distance shots between the driver and hybrids or long irons.Golf
Fairways HitBeginnerFairways hit tracks driving accuracy. This means the percentage of tee shots on par 4s and par 5s that finish in the fairway. This means a key input into greens in regulation, since a fairway lie makes hitting the green with the approach shot meaningfully easier.Golf
Fake ATPProA fake ATP is a deceptive shot where the player winds up as if going around the post, drawing the opponent wide, then redirects the ball crosscourt or down the line.Pickleball
Fake Bunt SlapAdvancedA fake bunt slap has the hitter show bunt to draw the corner infielders in. The next step is pull the bat back and slap the ball into the space the defense just vacated.Fast-Pitch Softball
Falling Forward Through ImpactIntermediateFalling forward through impact is an overcorrected weight shift where momentum carries the golfer's body noticeably past a balanced finish, toward or beyond the target, rather than finishing in control.Golf
Fast BallIntermediateA Fast Ball in padel is any shot struck with deliberate pace to reduce opponents' reaction time. This means most commonly a flat or light-topspin drive aimed at the body or feet of a net-zone player.Padel
Fault (General)BeginnerA fault is any rule violation that immediately ends a rally. This means including serve errors, non-volley zone violations, out-of-bounds shots, and illegal contact. This means and it always costs the serving team the point or serve.Pickleball
Feel vs RealIntermediate"Feel vs real" describes the frequent gap between what a golfer senses their body is doing during a swing and what a camera actually shows it doing. This means a mismatch that is completely normal and is exactly why video review is. As a result, valuable.Golf
Fence DistanceBeginnerFence distance is the measured distance from home plate to the outfield fence. Standard slow-pitch fields run 275–315 feet down the lines and 275–325 feet to center, though recreational parks vary widely.Slow-Pitch Softball
Fence-and-Glass Rebound ReadIntermediateA fence-and-glass rebound read is the skill of recognizing that the metal mesh sections of a padel court behave very differently from the glass panels. This means mesh absorbs pace and kills the bounce rather than rebounding it. This means and misreading which surface the ball is about to strike is a common source of defensive errors.Padel
Field Dimensions (Slow-Pitch)BeginnerSlow-pitch field dimensions define the base-path length (commonly 65 feet, longer than fast-pitch's 60). A related detail is the pitching distance (typically 50 feet for men's or mixed play, 46 in some youth divisions). The outfield fence distance (often 275 to 300 feet in recreational play), each of which can vary by league and division.Slow-Pitch Softball
Fielding FootworkBeginnerFielding footwork is how a player positions and moves their feet to field a ball cleanly and immediately set up a strong, accurate throw.Baseball
Fielding Position (Ready Stance)BeginnerThe fielding position is the pre-pitch stance a fielder holds to be ready to move right away in any direction. This means knees bent, weight forward, feet shoulder-width, on the balls of the feet.Baseball
Fifth Shot PatternAdvancedThe fifth shot pattern refers to the serving team's planned response on the fifth shot of the rally. This means typically a drop or drive based on what the fourth-shot return produces.Pickleball
Figure-8 Wind-UpIntermediateThe figure-8 wind-up is a distinct legal fast-pitch delivery style in which the pitching arm swings the ball down past the hip, back behind the body, and forward through release, tracing a figure-eight. This means the ball never travels over the head as it does in the windmill circle.Fast-Pitch Softball
First Baseman Bunt CoverageIntermediateFirst baseman bunt coverage is the responsibility to charge bunts hit toward the first-base line while the second baseman covers first base in her place.Fast-Pitch Softball
First Baseman StretchIntermediateThe first baseman stretch is the technique of extending one leg toward the incoming throw. At the same time, keeping the other foot anchored on the base, shortening the distance the ball must travel and getting the out a fraction of a second sooner.Slow-Pitch Softball
First Serve PercentageIntermediateFirst serve percentage is the share of first serves that land in the box, a core indicator of serve rhythm and risk management.Tennis
First StepIntermediateFirst step is how quickly a fielder initiates movement toward a batted ball — often the largest separator between good and great defenders.Baseball
First-and-Third DefenseAdvancedFirst-and-third defense is the set of defensive schemes used when runners are on both first and third, designed to prevent the runner on third from scoring. At the same time, still trying to get an out.Fast-Pitch Softball
First-Pitch Strike RateIntermediateFirst-pitch strike rate is the percentage of at-bats in which a pitcher throws a strike on the very first pitch, one of the strongest single indicators of overall pitching effectiveness and control of the count.Fast-Pitch Softball
First-Pitch Swing RateIntermediateFirst-pitch swing rate is the percentage of plate appearances in which a hitter swings at the very first pitch (the 0-0 count), used as a simple measure of a hitter's early-count aggressiveness.Baseball
First-Step QuicknessIntermediateFirst-step quickness is how fast a fielder's first movement reacts to a batted ball off the bat. This means widely considered the single biggest determinant of defensive range, more important than straight-line sprint speed.Baseball
Five-Tool PlayerIntermediateA five-tool player is a position player rated above-average or better in all five core scouting skills. This means hitting for average, hitting for power, running speed, arm strength, and fielding ability.Baseball
Flared DivotIntermediateA flared divot is wider or more angled at its start than at its end. This indicates the clubhead was rotating (opening or closing) through the strike rather than moving cleanly along a single path.Golf
Flat BackhandIntermediateA flat backhand is struck with minimal net racquet-face tilt and a swing path close to level through contact. This produces a low, penetrating trajectory with less topspin than a standard drive.Tennis
Flat Bat PathIntermediateA flat bat path travels roughly parallel to the ground through the contact zone. This means a reasonable path against a low, flatter arc. But a common cause of topped balls against a steeper, high-arc pitch.Slow-Pitch Softball
Flat DriveIntermediateA Flat Drive in padel is a low, fast, topspin-free groundstroke aimed to pass or pin opponents at the net by travelling fast through the court rather than over them.Padel
Flat ServeIntermediateA flat serve is struck with minimal spin at maximum racquet-head speed. This produces the highest velocity and least margin for error of the three main serve types.Tennis
FlickIntermediateThe flick is an attacking wrist stroke played to a full ball on the leg side. This uses a strong wrist roll to whip the ball to the mid-wicket or square-leg area.Cricket
Flick AttackAdvancedA flick attack is a sudden, wrist-driven acceleration on a mid-height dink that catches the opponent off guard with a sharp speed-up to the shoulder or hip.Pickleball
FlipIntermediateA flip is when the hands flick or scoop under the ball at impact rather than the shaft leaning forward. This means it adds loft, kills compression, and is a defensive reaction to poor sequencing.Golf
Flip-Flop RuleIntermediateThe flip-flop rule lets the home team bat first in the final inning of a time-limited game if the visiting team is leading. This gives the home team a fair last chance to respond instead of running out the clock without ever batting in a winning position.Slow-Pitch Softball
Flop ShotAdvancedA flop shot is a very high, soft-landing chip or pitch played with a wide-open lob wedge that stops quickly. This means used when there is little green between the ball and the hole.Golf
Flying ElbowIntermediateA flying elbow is the trail elbow lifting up and away from the body during the backswing, disconnecting the arms from the torso's rotation and often producing an overly steep, arms-dominant swing.Golf
Follow-ThroughBeginnerThe follow-through is the path the club takes after impact — swinging up and around to a balanced finish. It is not just cosmetic: a full, free finish confirms the swing was not decelerated through the ball.Golf
Follow-ThroughBeginnerThe follow-through is the path the racquet takes after contact. A complete finish confirms the swing was not decelerated before the ball was struck.Tennis
Follow-ThroughBeginnerFollow-through is the continuation of the paddle motion after contact. This means it determines ball direction, spin, and pace, and signals whether the swing was committed or interrupted early.Pickleball
Follow-ThroughBeginnerThe follow-through is the continuation of the swing after contact, where the bat completes its arc, the arms extend fully. The body finishes in a balanced, weight-forward position.Slow-Pitch Softball
Foot FaultBeginnerA foot fault occurs when a server's foot touches the baseline or crosses into the court before contacting the ball on the serve. This results in a fault.Tennis
Foot Fault (Pickleball)BeginnerA foot fault happens when the server's feet touch the baseline, the court. Another option is land outside the imaginary extensions of the sideline and center line at the moment the ball is struck.Pickleball
Footwear / CleatsBeginnerCleats provide traction on dirt and grass fields. Metal cleats are often restricted in recreational slow-pitch leagues; molded rubber or plastic cleats are the standard for safety and field preservation.Slow-Pitch Softball
FootworkBeginnerFootwork in padel encompasses all the movement patterns. This means split steps, side steps, sprints, and recovery steps. This means that position a player optimally to make their next shot with balance and power.Padel
FootworkBeginnerFootwork in cricket batting refers to the movement of the feet to get into the optimal position to play each delivery. This means moving quickly and correctly to the pitch of the ball is the basis of all good batting.Cricket
Footwork Ladder Pattern (Training)BeginnerA footwork ladder pattern is a repeated sequence of quick steps through a flat agility ladder, used off court to build the fast, precise foot placement tennis footwork depends on.Tennis
Force PlayBeginnerA force play is an out recorded by a fielder simply touching the base ahead of a runner who is required to advance, with no tag needed. This is. This is because the batter-runner or a trailing runner has no choice but to run to that base.Slow-Pitch Softball
Forced ErrorBeginnerA forced error is a mistake a player makes. This is because the opponent's previous shot was difficult enough. This means through pace, spin, placement, or depth. This means to genuinely warrant the miss.Tennis
ForehandBeginnerThe forehand is a groundstroke hit with the dominant arm swinging across the body from the non-dominant side, the most natural and typically most powerful shot in a player's arsenal.Tennis
Forehand DinkBeginnerA forehand dink is a soft, controlled shot hit on the dominant-hand side using a short pendulum motion of the paddle, arcing just over the net and dropping into the kitchen.Pickleball
Forward PressIntermediateA forward press is a small movement of the hands or right knee toward the target just before the takeaway. This means a trigger to start the swing in motion with consistent timing.Golf
Four-Seam FastballBeginnerThe four-seam fastball is the most common pitch in baseball — gripped across all four seams — and is typically the hardest, straightest pitch a pitcher throws.Baseball
Four-Seam Grip (Throwing)BeginnerGripping the ball across four seams before a throw. Instead of however it lies in the glove. This means produces a straight, true throw with maximum carry, the fielding equivalent of a pitcher's four-seam fastball grip.Baseball
Frame RateIntermediateFrame rate (frames per second, fps) is how many individual images your camera captures each second. This means higher frame rates freeze fast motion better and produce more reliable pose tracking.Analysis Concepts
Frame Rate (Video Capture)IntermediateFrame rate is how many individual images per second a video captures. It directly determines how precisely fast-moving moments of a golf swing. This means especially impact. This means can be measured from that footage.Golf
FramingAdvancedFraming is a catcher's subtle technique of receiving borderline pitches in a way that influences the umpire to call them strikes. This means using glove angle, body stillness, and soft hands.Fast-Pitch Softball
Framing a PitchAdvancedFraming is a catcher's glove technique for receiving a borderline pitch in a way. This means soft hands, minimal extra movement, sticking the pitch where it arrives. This means that presents it favorably to the umpire as a strike.Baseball
Framing the BallBeginnerFraming the ball means the ball contacts the outer rim of the racquet head instead of the string bed. This usually producing a weak, hard to predict, and often mis-directed shot.Tennis
Free ReliefIntermediateFree relief means moving the ball to a better spot with no penalty stroke added. This means available for situations like an immovable obstruction, ground under repair, or an embedded ball, distinguishing it from penalty relief options like unplayable lie or a penalty area.Golf
Front Door Breaking BallAdvancedA front door breaking ball starts inside on a same-handed batter. This means looking like it may hit them. This means and breaks back over the inside corner for a strike instead of a ball or hit-by-pitch.Baseball
Front Foot LandingBeginnerFront foot landing is the moment the stride foot plants and becomes the stable post the hips rotate against. This means its timing relative to the pitcher's release is the single biggest factor separating on-time hitters from late or rushed ones.Baseball
Front Foot Timing StepBeginnerThe front foot timing step is the small stride or weight-transfer movement a hitter makes with the lead foot to synchronize the swing to the pitcher's delivery, distinct from the swing itself.Fast-Pitch Softball
Front Shoulder Flying OpenIntermediateThe front shoulder flying open is a fault where the lead shoulder rotates toward the pitcher too early, pulling the eyes and barrel off the ball before contact and causing weak, pulled contact or a swing-and-miss.Baseball
Front Shoulder Pull-OffIntermediateFront shoulder pull-off is when the lead shoulder flies open and pulls away from the ball early in the swing, dragging the eyes, head, and bat path off line before contact.Slow-Pitch Softball
Front-Foot DefenceBeginnerThe front-foot defence is a defensive batting stroke where the batter strides forward and blocks a good-length ball with a straight, angled bat to keep it down and safe.Cricket
Frying Pan GripBeginnerThe frying pan grip is a beginner forehand grip where the racquet face is held flat like a frying pan. This is actually a continental grip used incorrectly for groundstrokes.Tennis
Full TossBeginnerA full toss is a delivery that reaches the batter without pitching on the ground — arriving above waist height on the full. A deliberate waist-high full toss is called a beamer and is illegal.Cricket
Game-Improvement IronsBeginnerGame-improvement irons use a wide sole, thick top line, and hollow or heavily perimeter-weighted construction to maximize forgiveness and launch. This means the recommended category for the large majority of recreational golfers.Golf
Gap WedgeBeginnerThe gap wedge, typically 50° to 52° of loft, fills the yardage hole between a pitching wedge and a sand wedge. This means some manufacturers market the identical club as an "approach wedge" or "A-wedge."Golf
Gap-to-Gap HittingIntermediateGap-to-gap hitting is targeting hard line drives into the outfield gaps rather than swinging for the fence. This means the high-percentage approach in leagues with home-run limits and the foundation of consistent run production in slow pitch.Slow-Pitch Softball
Gear EffectIntermediateGear effect is the extra spin and directional change produced when the ball is struck away from the clubface's center of gravity. This causes the clubhead to twist slightly at impact like two meshing gears.Golf
Gimme PuttBeginnerA "gimme" is a short putt that playing partners agree is close enough to the hole that it can be counted as made without actually being holed. This means a casual convention rather than an official rule, and formally allowed only in match play through a genuine concession.Golf
GlanceIntermediateThe glance (or leg glance) is a wristy deflection played to a ball on the leg side, angling the bat face to direct the ball fine to leg without force.Cricket
Glass Angle MiscalculationIntermediateA glass angle miscalculation is the common defensive error of misjudging where a ball will emerge after striking the glass. This means usually underestimating how much spin alters the rebound. This means leaving a player positioned for a straight, mirrored bounce. At the same time, the ball actually kicks away at a sharper or flatter angle than expected.Padel
Glass ReadingIntermediateGlass Reading is the skill of predicting how fast and at what angle a ball will rebound off the back or side glass. As a result, you can position yourself early and play the shot cleanly.Padel
GlideAdvancedThe glide is a delicate deflection played to a full or good-length ball outside off stump. This uses an open bat face to steer the ball fine on the off side between slip and third man.Cricket
GloboBeginnerGlobo is the Spanish term universally used in padel for any lob. This means a high arc shot hit over the net opponents. This means and is arguably the single most important shot in the sport.Padel
Glove – Slow-PitchBeginnerA slow-pitch softball glove is sized for the larger 12-inch ball. This means typically 12 to 13.5 inches for infielders, up to 14 inches for outfielders. This means with a deeper, wider pocket than a baseball glove.Slow-Pitch Softball
Glove PresentationIntermediateGlove presentation (for catchers) is how the catcher holds and moves the mitt to receive the pitch cleanly and, in competitive baseball, to subtly show the umpire the ball in the strike zone.Baseball
Glove-Side BackhandAdvancedA glove-side backhand is fielding a ground ball hit to the fielder's glove-hand side by reaching across the body with the glove turned outward, rather than shuffling the feet to field it squarely.Slow-Pitch Softball
Golden Ball – Punto de OroBeginnerThe Golden Ball (Punto de Oro) is a sudden-death deciding point played when a game reaches deuce (40–40), with the receiving pair choosing which player will receive the serve.Padel
Golden DuckBeginnerA golden duck is when a batter is dismissed for zero runs on the very first ball they face in an innings. This means the most emphatic possible batting failure.Cricket
Golden PointBeginnerA Golden Point in padel refers to any single decisive point at a critical juncture of a match. This means most commonly the Punto de Oro at game deuce. This means where the outcome of the point decides the game, set, or match.Padel
Golden Point StrategyIntermediateGolden Point Strategy is how a pair tactically constructs the single sudden-death point at 40–40. This means who serves, who receives, what serve target and shot pattern to commit to. Instead of simply knowing what the Golden Point is.Padel
Golden Position at KitchenIntermediateThe golden position is the optimal stance at the kitchen line. This means about one foot behind the NVZ line, balanced and paddle-ready. This comes from which a player can cover the widest range of shots without sacrificing dink quality.Pickleball
Golf Ball Compression RatingIntermediateCompression rating describes how much a golf ball deforms at impact. This means lower-compression balls suit slower swing speeds and feel softer. At the same time, higher-compression balls suit faster swing speeds and feel firmer, though modern ball design has narrowed the practical difference.Golf
Golf Ball DimplesBeginnerDimples are the small indentations covering a golf ball's surface that reduce aerodynamic drag and manage lift, letting the ball fly farther and more predictably than a smooth ball would.Golf
Golf Swing BasicsBeginnerGolf swing basics are the handful of fundamentals. This means grip, stance, posture. A simple takeaway. This means that everything else in the swing is built on, and getting these right before adding complexity prevents most early bad habits.Golf
Good LengthBeginnerA good-length delivery is one that pitches at the spot that forces the batter to be uncertain whether to play off the front foot or the back foot. This means the most dangerous line for any bowler.Cricket
Good MissAdvancedA good miss is the preferred side to miss on a given shot. This means the direction or location where an error results in the easiest recovery or least damage.Golf
GooglyAdvancedA googly is a deceptive wrist-spin delivery from a leg-spinner that turns the opposite way to the stock ball. This means toward a right-handed batter instead of away. This means disguised by an identical action.Cricket
Green ReadingIntermediateGreen reading is assessing the slope, grain, and speed of a putting surface to predict how much and which way the ball will curve from its starting line to the hole.Golf
Greens in Regulation (GIR)BeginnerGreens in Regulation (GIR) counts how often a golfer reaches the putting surface in "regulation". This means two strokes fewer than par (par minus 2). This means and is the single most commonly used measure of overall ball-striking quality.Golf
Greenside Bunker TechniqueIntermediateGreenside bunker technique opens the stance and clubface, aims a few inches behind the ball, and swings through the sand rather than at the ball. This means the club never actually contacts the ball directly on a properly played bunker shot.Golf
GripBeginnerThe grip is how your hands hold the club. It is the only contact you have with the club, so it controls the clubface more than any other fundamental.Golf
Grip ChangeIntermediateA grip change is the adjustment of hand position on the handle between shots to match the optimal grip for the incoming shot type. This means most commonly shifting from a forehand grip to continental for volleys, serves, or slices.Tennis
Grip Change Speed Between ShotsIntermediateGrip change speed is how quickly and reliably a player rotates the racquet in their hand between strokes that require different grips. A slow or incomplete change is a frequent hidden cause of mis-hits.Tennis
Grip PressureBeginnerGrip pressure is how tightly the hands hold the club. Most instructors recommend a light-to-moderate pressure — enough to hold the club securely, loose enough to allow wrist hinge and a free release.Golf
Grip Pressure (Tennis)BeginnerGrip pressure is how tightly a player holds the racquet handle. It should generally stay relaxed through most of the swing, firming only briefly at the moment of contact.Tennis
Grip SizeIntermediateGrip size. This means undersize, standard, midsize, or oversize. This means is fit to hand size and can also be used to quiet an overactive release. This means a slightly larger grip tends to reduce excess hand action through impact.Golf
GroovesIntermediateGrooves are the channel-like lines on the clubface that channel away water and debris, grip the ball surface, and generate spin. This means especially critical for wedge shots from rough and wet conditions.Golf
Ground Ball RateIntermediateGround ball rate (GB%) is the percentage of batted balls that are grounders. This means typically a negative indicator for power hitters, though contact hitters may use it strategically.Baseball
Ground Ball vs Fly Ball TendencyAdvancedGround ball versus fly ball tendency describes the overall shape of a hitter's batted-ball distribution. This means whether their typical attack angle produces mostly grounders, a balanced mix, or mostly fly balls. This means as a single profile rather than one isolated rate.Baseball
Ground FieldingBeginnerGround fielding is the skill of intercepting, picking up, and controlling cricket balls rolling or bouncing along the ground, forming the majority of fielding actions during a match.Cricket
Ground ForceProGround force in golf is the vertical and horizontal force a golfer pushes into the ground during the swing. More effective ground use translates directly into club speed and power.Golf
Ground Reaction ForceAdvancedGround Reaction Force (GRF) is the force the ground exerts back against an athlete's feet. This means the foundational energy input for the kinematic chain in every swing sport.Analysis Concepts
Ground-First ContactIntermediateGround-first contact means the club strikes the turf before reaching the ball. A related detail is the general full-swing version of a fat or chunked shot, caused by the swing's low point arriving too early.Golf
Half-VolleyAdvancedA half-volley is struck immediately after the ball bounces, contacting it at ankle or shoe height before it rises. This means a reactive "scoop" that requires exceptional timing and low body position.Tennis
Half-VolleyIntermediateA Half-Volley in padel is struck immediately after the ball bounces. This means essentially scooping it off the ground. This means typically used as an emergency shot when the ball lands at the feet in the net zone.Padel
Half-Volley (Pickleball)IntermediateA half-volley is a shot taken immediately after the ball bounces, contacted very low to the ground before it has risen to a comfortable height. This means common when caught mid-transition-zone.Pickleball
Hand PathIntermediateHand path is the route the hands travel from launch position to contact. This means an efficient, direct path to the ball keeps the barrel in the zone longer and prevents casting.Baseball
Hand SpeedIntermediateHand speed is how quickly the hands accelerate the bat head through the hitting zone. Faster hands produce more bat speed, higher exit velocity, and more time to read the pitch before committing.Slow-Pitch Softball
Hand-Eye Timing DrillsBeginnerHand-eye timing drills are focused practice routines. This means reaction balls, varied-speed machine reps, short-distance soft toss. This means designed in particular to sharpen a hitter's ability to read release and adjust swing timing, separate from pure swing-mechanics work.Fast-Pitch Softball
Handicap IndexBeginnerA Handicap Index is the World Handicap System (WHS) measure of a golfer's demonstrated playing ability on a neutral course. A lower index means a better player.Golf
Handle DragAdvancedHandle drag is the trail hand pulling the grip end of the club down and forward through the downswing. As a result, the handle leads the clubhead into impact, the mechanism that creates forward shaft lean and compression.Golf
Hands BattleAdvancedA hands battle is a rapid-fire exchange at the kitchen line where both teams speed up and counter-attack in quick succession. This means won through reaction speed, paddle readiness, and placement under pressure.Pickleball
Hanging BackIntermediateHanging back is insufficient weight transfer to the lead side by impact. This leaves the body's weight predominantly on the trail foot at the moment of the strike.Golf
Hard-Hit RateAdvancedHard-hit rate is the percentage of batted balls struck above a set exit-velocity threshold — typically 95 mph in MLB, scaled lower for amateur levels. It measures contact quality independent of luck.Baseball
Head Movement (Batting)IntermediateHead movement is excess drift, bob, or tilt of the head during the swing. This means a moving visual reference point makes it harder to track the ball accurately and reliably find the barrel.Baseball
Head PositionBeginnerHead position in batting refers to where and how still the batter's head is during the stroke. This means keeping the head level, forward-leaning, and over the ball is a universal marker of quality technique.Cricket
Heel StrikeIntermediateA heel strike is contact made closer to the shaft than the center of the clubface. This produces horizontal gear effect that pushes the ball right and reduces ball speed.Golf
Heuristic AnalysisBeginnerHeuristic analysis is smart, rules-and-pattern-based analysis that reads observable cues to surface what is most likely happening in your swing. This means a confident, data-backed estimate, not a guess.Analysis Concepts
Heuristic DataIntermediateHeuristic data is information read through encoded expert rules of thumb to surface the most likely pattern quickly and reliably. This means a confident estimate, not a measured result.Analysis Concepts
Heuristic EngineIntermediateThe heuristic engine is the deterministic, rules-based part of SwingVantage that runs first on every analysis — no external AI call required.Analysis Concepts
High Cut ShotAdvancedA high cut shot is a deliberately high-launching left-to-right shot that lands softly with minimal roll. This is useful for stopping the ball quickly on firm greens or navigating around trouble on the left side of a hole.Golf
High Defensive LobBeginnerA High Defensive Lob is an extreme-height version of the defensive lob. This means launched as high as the enclosure allows. This means primarily to buy maximum recovery time when defending under severe pressure.Padel
High Pitch HandlingIntermediateHigh pitch handling is the discipline and technique to either lay off rise balls above the zone or, when swinging, use a flat-to-slightly-upward bat path to make solid contact rather than swinging under them.Fast-Pitch Softball
High-Hands SetupBeginnerHigh hands in the stance or load position means the hands are set above the back shoulder. This means a launch position that gives the barrel a longer, downward-into-the-zone path to the ball.Baseball
High-Spin MissAdvancedA high-spin miss is a shot with excessive backspin that climbs too steeply, loses forward momentum, and falls short of its expected distance. This means most commonly from a high-face driver strike or a steep angle of attack.Golf
Hip ClearanceAdvancedHip clearance is the rotation of the lead hip out of the way through impact. This creates room for the arms and club to swing freely past the body.Golf
Hip HingeBeginnerThe hip hinge is bending forward from the hip joints (not the waist) to establish the correct spine angle at address. It is the foundation of athletic posture in golf.Golf
Hip RotationIntermediateHip rotation in tennis is the turning of the pelvis from the coiled backswing position toward the target during the forward swing, the primary driver of power in the kinetic chain.Tennis
Hip RotationIntermediateHip rotation is the turning of the hips toward the pitcher during the swing — the single biggest source of rotational power in a slow-pitch hitter.Slow-Pitch Softball
Hip Rotation – BattingIntermediateHip rotation in batting is the explosive turn of the hips toward the pitcher that initiates the kinetic chain from lower body to bat, generating power and bat speed at contact.Fast-Pitch Softball
Hip Rotation (Batting)IntermediateHip rotation in batting is the aggressive turning of the hips toward the pitcher to initiate the swing. This means the engine that drives rotational power before the hands or barrel move.Baseball
Hip Snap – PitchingIntermediateHip snap is the rapid rotation of the pitcher's hips from the open, sideways stride position back to square with the plate. This means closing the hips. This means transferring lower-body momentum into the torso and arm just before release.Fast-Pitch Softball
Hip TurnIntermediateHip turn is the rotation of the pelvis around the spine during the golf swing. In the backswing it resists the shoulder coil; in the downswing it leads the kinetic chain to generate speed.Golf
Hip-Shoulder SeparationProHip-shoulder separation is the difference in rotation between the hips and the shoulders during the swing. The hips fire first while the shoulders stay back, creating stored torque that whips the bat through.Baseball
Hip–Shoulder SeparationAdvancedHip–shoulder separation is the angular gap between the hips and shoulders at the start of the downswing. A larger, well-timed gap stretches the core and releases into club speed.Golf
Hit and RunIntermediateThe hit and run is an offensive play where the baserunner breaks toward the next base on the pitch, committing the defense. At the same time, the hitter makes contact to put the ball in play and protect the running runner.Fast-Pitch Softball
Hit-and-RunIntermediateA hit-and-run is a play call in which a baserunner takes off toward the next base as the pitch is thrown. The hitter is required to swing and make contact. This means ideally putting the ball in play on the ground. This means to protect the runner.Baseball
Hitch in the SwingIntermediateA hitch is an extra downward or backward dip of the hands after the load has already started forward, effectively creating a second, unplanned load that costs precious time against velocity.Baseball
Hitting Off the Back FootIntermediateHitting off the back foot means the hitter's weight stays planted on the back leg through contact instead of transferring forward. This produces an arm-only swing with little rotational power.Slow-Pitch Softball
Hitting Off the Front FootIntermediateHitting off the front foot means the hitter's weight has fully transferred forward before contact. This leaves no back-side push to power the swing and often causing early, weak contact.Slow-Pitch Softball
Hitting the DropAdvancedHitting the drop is the swing adjustment of angling the bat path downward through the zone to match a drop ball's late downward break. Instead of swinging on a flat plane and rolling over the top of the pitch.Fast-Pitch Softball
Hitting the RiseAdvancedHitting the rise is the specific swing adjustment. This means staying tall through contact and tracking the ball up through the zone rather than swinging down. This means needed to square up a well-located rise ball rather than swinging under it.Fast-Pitch Softball
Hitting Zone WidthIntermediateHitting zone width is how much room a hitter's bat path stays flat or near-flat through the contact area. This gives a wider window in which solid contact is still possible even with imperfect timing.Slow-Pitch Softball
Home Run LimitBeginnerA home run limit is a per-game cap on how many over-the-fence hits a team may count as home runs. Additional fence-clearing hits are called back as outs or singles — the rule exists to keep games competitive when hot equipment makes fence shots routine.Slow-Pitch Softball
Home-to-First TimeIntermediateHome-to-first time is a stopwatch measurement of the seconds it takes a batter to travel from contact at home plate to touching first base, used as a standardized speed benchmark in evaluation and recruiting.Fast-Pitch Softball
HookBeginnerA hook is a shot that curves sharply toward and past the target line — to the left for a right-handed golfer. It happens when the clubface is closed relative to the swing path at impact.Golf
Hook ShotIntermediateThe hook shot is an attacking batting stroke played to a short-pitched, rising ball aimed at the body or head. This means the batter pivots and whips the ball to the leg side, often in front of square.Cricket
Horizontal BreakProHorizontal break is the lateral movement a pitch generates from spin, measured in inches to the arm side (positive) or glove side (negative).Baseball
Horizontal Gear EffectAdvancedHorizontal gear effect is the sidespin added when the ball is struck toward the heel or toe of the face, curving the ball opposite the direction of the miss. This means toe strikes tend to draw, heel strikes tend to fade.Golf
Hybrid ClubBeginnerA hybrid blends a fairway wood's wider sole and higher launch with an iron's shorter length and more upright lie. This makes long-distance shots easier to hit high and land softly than a comparable long iron.Golf
I-Formation (Doubles)AdvancedThe I-formation has the server's net partner crouch on the center service line before the serve, disguising which side of the court they will cover and setting up a planned poach.Tennis
Illegal Bat ListBeginnerAn illegal bat list names bat models that a softball association has removed from legal play. Testing may show that a listed bat exceeds the allowed performance limit.Slow-Pitch Softball
Illegal PitchBeginnerAn illegal pitch is any delivery that violates the rules. This means most commonly a pitch outside the legal arc window, a spin-thrown ball, or a release from an illegal position.Slow-Pitch Softball
Impact PositionIntermediateImpact position is the body and club configuration at the exact moment the clubface meets the ball. This means the single frame of the swing that determines ball flight more than any other point.Golf
Improvement DeltaIntermediateAn improvement delta is the measured difference between a baseline value and the most recent measurement for the same metric. This means the hard number behind "did I get better?"Analysis Concepts
In-Between HopAdvancedThe in-between hop is the awkward bounce that arrives at a fielder's shin or knee height rather than as a clean short hop or a rising long hop. This means the hardest hop to field and a common source of errors.Baseball
In-Between Hop (Slow-Pitch)IntermediateThe in-between hop is the awkward moment mid-bounce when a ground ball is neither a clean short hop nor a clean high hop. This means the hardest timing to field cleanly. This requires a fielder to adjust their glove height at the last instant.Slow-Pitch Softball
In-SwingIntermediateIn-swing is conventional swing bowling where the ball curves in the air from off to leg (in towards the body of a right-handed batter), often targeting the stumps or pads.Cricket
In-to-OutIntermediateAn in-to-out club path means the clubhead is moving to the right of the target line through impact (for a right-hander). It is the draw and hook path — the opposite of over the top.Golf
Induced Vertical Break (IVB)ProInduced vertical break is the vertical movement a pitch achieves purely from spin, measured against a hypothetical spinless ball — isolating the Magnus effect from gravity.Baseball
Infield DepthIntermediateInfield depth is how far the infielders play from home plate. This means "in" (shaded forward to cut off a run) or "back" (standard depth to maximize range on ground balls and line drives).Slow-Pitch Softball
Innings Limit (Youth)BeginnerAn innings limit is a cap on the total number of innings a young pitcher is permitted or recommended to throw across a season or year, intended to manage cumulative throwing workload beyond any single game's pitch count.Baseball
Inside Pitch ApproachIntermediateThe inside pitch approach is the technique for hitting a ball on the inner third of the plate. This means pulling the hands in, getting the barrel through early, and driving the ball to the pull side.Fast-Pitch Softball
Inside vs Outside PitchBeginnerAn inside pitch crosses the inner half of the plate, nearest the hitter; an outside pitch crosses the outer half, away from the hitter. Each requires a different contact point and field direction.Slow-Pitch Softball
Inside-Out ForehandIntermediateAn inside-out forehand is played by running around a ball that arrives on the backhand side and redirecting it with the forehand to the opponent's backhand corner.Tennis
Instant EstimateBeginnerAn Instant Estimate is a fast, heuristic-only analysis result available immediately after upload. This means clearly labeled as an estimate derived from rules, before any AI-enhanced processing completes.Analysis Concepts
Interlocking GripBeginnerThe interlocking grip links the lead hand's index finger with the trail hand's pinky finger, weaving the two hands together. This means a popular choice for players with smaller or weaker hands, including many tour pro players.Golf
Interpreted ValueIntermediateAn interpreted value is a judgment or label that emerged from AI reasoning applied to raw data. This means such as 'likely timing issue' or 'probable hip stall'. Instead of from a direct measurement or a deterministic rule.Analysis Concepts
Iron Contact PointIntermediateIron contact point is the specific spot on the clubface where the ball is struck. This determines ball speed, spin consistency. The direction of any gear-effect curve, independent of swing path and face angle.Golf
ISA League FormatBeginnerISA (Independent Softball Association) is one of several regional or specialty sanctioning bodies for slow-pitch softball, maintaining its own bat-certification standard and rule variations that a team must confirm separately from USSSA or USA Softball requirements.Slow-Pitch Softball
JudgmentIntermediateJudgment in cricket batting is the ability to quickly decide which deliveries to play and which to leave, choosing the right shot for each ball bowled.Cricket
Jump (Stolen Base)IntermediateThe jump on a stolen base attempt is how quickly and decisively a runner breaks toward the next base on the pitcher's first movement. This means the single biggest predictor of stolen base success.Baseball
Kick ServeAdvancedA kick serve combines heavy topspin with side spin to clear the net safely and then bounce high and kick sideways. This makes it the standard high-level second serve. This is because of its margin and awkward bounce.Tennis
Kick ServeAdvancedA Kick Serve in padel is an underarm serve struck with topspin. As a result, after bouncing in the service box it accelerates and kicks up or to the side. This makes the return more awkward than a flat serve.Padel
Kick Serve Spin DirectionAdvancedKick serve spin direction refers to the diagonal axis of topspin-sidespin that makes a kick serve jump up and away from the returner after the bounce.Tennis
Kinematic ChainIntermediateThe kinematic chain is the sequence of body segments. This comes from ground to tip. This means through which force and speed are transferred in a swing, with each segment's energy amplifying the next.Analysis Concepts
Kinematic SequenceProThe kinematic sequence is the order in which body segments accelerate and decelerate during the downswing: pelvis → torso → lead arm → clubhead. Each segment slingshots the next for maximum speed.Golf
Kinetic ChainProThe kinetic chain is the linked sequence of body segments. This means feet, knees, hips, torso, shoulders, arms, wrists, club. This means where each segment transfers and amplifies energy to the next.Golf
Kinetic ChainIntermediateThe kinetic chain in tennis is the sequential transfer of force from the ground up through the legs, hips, torso, shoulder, arm, and racquet, each segment accelerating the next to multiply racquet-head speed.Tennis
Kinetic Chain BreakdownIntermediateA kinetic chain breakdown happens when the ground-up sequence of leg, hip, torso, and arm rotation is interrupted or skipped. This forces the arm to generate power on its own instead of receiving it from the body.Tennis
Kitchen (Non-Volley Zone)BeginnerThe kitchen is the 7-foot non-volley zone on each side of the net. You may not hit a volley (a ball out of the air). At the same time, standing in it or touching its line. This means you must let the ball bounce first.Pickleball
Kitchen Line BattleIntermediateA kitchen line battle is the sustained exchange that happens once both teams have reached the non-volley zone line, combining dinks, speed-ups, and volleys until one side forces an error or opening.Pickleball
Kitchen Line PositionBeginnerKitchen line position refers to standing as close to the non-volley zone line as legally possible. This maximizes net coverage and offensive angle. At the same time, minimizing the court area opponents can attack.Pickleball
Knee FlexBeginnerKnee flex at address is the slight bend in the knees that creates an athletic, ready posture. This means enough to feel springy and stable, not. As a result, much that it restricts hip rotation.Golf
Knock-Down ShotIntermediateA knock-down shot is an approach shot deliberately hit with a lower, more controlled trajectory than normal. This means usually with more club and a shorter, three-quarter swing. This means to fight wind or control distance more precisely.Golf
Knuckle CurveAdvancedA knuckle curve is a curveball variation gripped with one finger (usually the index) bent and pressed knuckle-first against the ball, instead of laid flat. This produces a tighter spin axis and a later, sharper break.Baseball
Knuckleball – Fast-PitchAdvancedA fast-pitch knuckleball is thrown with minimal spin. As a result, air turbulence causes the ball to flutter erratically. This makes it nearly impossible to predict. This means for the hitter or the catcher.Fast-Pitch Softball
LagAdvancedLag is the acute angle between the lead arm and the shaft in the downswing. This means the loaded position that releases into club speed at impact when timed correctly.Golf
Lag PuttingIntermediateLag putting is the deliberate strategy of prioritizing distance control over making a long putt, aiming to leave a short, stress-free second putt rather than attacking the hole aggressively.Golf
Landmark TrackingIntermediateLandmark tracking follows the position of each detected body keypoint across consecutive video frames. This creates a time-series trajectory for every joint that enables timing and velocity measurements.Analysis Concepts
Late Contact (Slow-Pitch)IntermediateLate contact happens when the bat meets the ball behind the ideal contact point. This means closer to or behind the back edge of the plate. This means usually producing weak contact to the opposite field or a foul ball.Slow-Pitch Softball
Late Contact (Tennis)IntermediateLate contact means the racquet meets the ball behind the ideal contact point. This means usually behind the front hip. This means which robs the shot of pace, direction control, and spin.Tennis
Late CutAdvancedThe late cut is a delicate batting stroke played to a short, wide ball outside off stump. This uses soft wrists to deflect the ball very fine to third man after it has almost passed the batter.Cricket
Late LoadIntermediateA late load is starting the weight shift and hand-back motion later than the pitch's flight time allows. This leaves too little time to complete a full, balanced swing before the ball arrives.Slow-Pitch Softball
Late Split StepIntermediateA late split step lands after the opponent has already struck the ball, meaning the player is still airborne or resettling exactly when they need to be pushing off toward the shot.Tennis
Late Swing TriggerBeginnerA late swing trigger is a timing mistake in which the hitter starts the swing too far after the ball's release. This most often produces weak contact toward the opposite field or a complete miss on velocity the hitter did not expect.Fast-Pitch Softball
Lateral ShiftAdvancedA lateral shift is the small move of the hips toward the target at the start of the downswing. It moves the low point forward and sets up the lead-side post, working with hip rotation rather than replacing it.Golf
Launch AngleIntermediateLaunch angle is the vertical angle, in degrees above horizontal, at which the ball leaves the face. Together with spin it determines how high and far the ball flies.Golf
Launch Angle (Batting)IntermediateLaunch angle in batting is the vertical angle the ball leaves the bat. Roughly 10–25° produces the hardest, most productive contact.Baseball
Launch Angle (Slow-Pitch)IntermediateLaunch angle is the vertical angle at which the ball leaves the bat relative to the ground. This means too low produces ground balls, too high produces pop-ups. A moderate range produces line drives and gap shots.Slow-Pitch Softball
Launch MonitorIntermediateA launch monitor is a device that measures ball and clubhead data at impact. This means ball speed, launch angle, spin rate, and club speed. This means using radar or camera sensors to quantify a shot instead of relying on how it looked.Golf
LBW (Leg Before Wicket)BeginnerLBW is a mode of dismissal. This means if the ball would have hit the stumps but the batter's pad intercepts it first. This means under specific conditions. This means the umpire can rule them leg before wicket.Cricket
Lead Arm BendIntermediateLead arm bend is excessive folding of the lead elbow during the backswing. This involves shortening the swing's radius and reducing the width and stored power a fully extended backswing would otherwise create.Golf
Lead Off BaseBeginnerA lead off base is the distance a baserunner takes from the bag before the pitch. This means maximising lead distance reduces the distance to the next base. At the same time, managing pickoff risk.Baseball
Lead TimingIntermediateLead timing is when and how far a baserunner leaves the base in anticipation of a pitch being put in play or a steal attempt. This requires coordination with the pitcher's release point.Fast-Pitch Softball
Lead WristIntermediateThe lead wrist is the wrist of the top hand (left for right-handers). Its position throughout the swing — especially at the top of the backswing and at impact — directly controls clubface angle and low point.Golf
Left-Side Defense vs SlappersAdvancedLeft-side defense against slappers adjusts the shortstop and third baseman's positioning and first-step reads to cover both a slapped ground ball and a bunt from a left-handed slap hitter.Fast-Pitch Softball
Leg Drive – PitchingIntermediateLeg drive is the forward force the pivot leg generates against the rubber to launch the pitcher's body toward home plate, forming the base of the kinetic chain the windmill arm circle rides on top of.Fast-Pitch Softball
Leg Drive on GroundstrokesIntermediateLeg drive is the push off the ground during a groundstroke that initiates the kinetic chain, converting ground reaction force into upward and rotational energy that feeds into the hips, torso, and arm.Tennis
Leg KickIntermediateA leg kick is a pronounced lift of the front knee during the load, used to build extra rhythm and stored energy before the stride and swing fire. This means a bigger, higher-risk trigger than a toe tap or no-stride approach.Baseball
Leg-CutterAdvancedThe leg-cutter is a pace bowling variation where the ball is cut off the middle and ring fingers to move towards the leg side off the pitch, acting like a slow leg-break.Cricket
Leg-SpinIntermediateLeg-spin is a type of spin bowling where a right-arm bowler spins the ball from leg to off (from right to left as seen by the batter). This uses wrist rotation to impart heavy clockwise topspin.Cricket
Legal DeliveryBeginnerA legal delivery in slow-pitch softball is a pitch that is released underhand with a smooth, continuous motion and arrives within the required arc height. This means typically between 6 and 12 feet. This means over the plate.Slow-Pitch Softball
Let (Serve Rule)BeginnerA let is called when a serve clips the net cord and still lands in the correct service box. This requires the point to be replayed with no penalty to the server.Tennis
Let Serve Rule (Pickleball)BeginnerA "let" traditionally means a serve that clips the net and lands in is replayed. This means but current pickleball rules eliminated that provision. As a result, a serve that ticks the net and lands in the correct service court is simply live.Pickleball
Letting the Ball GoBeginnerLetting the Ball Go means intentionally allowing a fast or deep ball to pass you and rebound off the back glass rather than volleying or striking it in the air. This turns a potential winner into a manageable rebound shot.Padel
Lie AngleAdvancedLie angle is the angle between the shaft and the ground when the club is soled correctly. A lie angle that is too upright pulls shots left; too flat and they drift right (for a right-hander).Golf
Lighting ConditionsBeginnerLighting conditions describe how evenly and brightly the subject is illuminated. This means poor lighting is one of the top causes of low-quality video and degraded pose estimation.Analysis Concepts
Line Call EtiquetteIntermediateIn self-officiated play, the side of the court where the ball landed makes the call, benefit of the doubt goes to the opponent on close or unsure calls, and calls are made immediately, not after the fact.Pickleball
Line Drive RateIntermediateLine drive rate (LD%) is the percentage of batted balls classified as line drives (typically 0–25° launch angle with hard contact). This means the batted-ball type with the highest expected batting average.Baseball
Lineup StrategyAdvancedLineup strategy is the deliberate construction of the batting order to maximize run production. This means pairing on-base skills at the top with power at the middle spots and reliable contact throughout.Slow-Pitch Softball
LoadBeginnerThe load is the small backward gathering of the hands and weight just before the swing initiates. This means coiling the body to store elastic energy that fires into the ball when the swing begins.Baseball
LoadBeginnerThe load is the backward weight shift and hand coil that sets the hitter in a ready, wound-up position before initiating the swing. In slow pitch, the load must happen early and hold while the long-arcing ball descends.Slow-Pitch Softball
Load Timing (Hitting)IntermediateLoad timing is when and how a hitter shifts weight back and coils the upper body in preparation for the swing, synchronized to the pitcher's delivery rather than started on a fixed internal clock.Fast-Pitch Softball
LobIntermediateA lob is a high, arcing shot designed to clear a net player's reach, either buying time defensively or winning the point offensively with a topspin arc that lands near the baseline.Tennis
LobIntermediateA lob is a high-arcing shot hit over the opponents' heads, forcing them off the kitchen line and back toward the baseline.Pickleball
LobBeginnerA lob is a high, deep shot hit over the net opponents to push them back from their attacking position. This means the most important defensive weapon in padel and the primary tool for reclaiming the rally from a losing position.Padel
Lob DefenseBeginnerLob defense is using a high, deep shot over an approaching or net-positioned opponent to buy time, reset the point, or force a difficult overhead.Tennis
Lob to the GlassIntermediateA lob to the glass is a defensive or neutralizing lob deliberately aimed to land and die close to the back glass rather than simply hit deep. This uses the wall to compress the ball's remaining bounce and deny the net pair a comfortable, well-timed overhead.Padel
Lob Wedge ShotIntermediateA lob wedge shot uses the most-lofted club in the bag (58–64°) to produce a high, soft-landing shot. This means most effective when you need to carry a hazard and stop quickly on a small target.Golf
Local RuleIntermediateA local rule is a course- or competition-specific modification adopted by the committee running play. This means commonly covering embedded balls, temporary conditions like winter rules, or unique course features not addressed by the standard Rules of Golf.Golf
Loft GappingIntermediateLoft gapping is checking that consecutive clubs in a bag. This means especially wedges. This means are spaced by consistent loft and yardage increments. As a result, there are no large distance gaps or overlapping distances between neighboring clubs.Golf
Long Backswing Timing IssueIntermediateA long backswing timing issue occurs when the backswing takes longer to complete than the ball allows. This forces a rushed or unfinished forward swing regardless of how clean the backswing shape looks in isolation.Tennis
Long Toss ProgramIntermediateA long toss program is a structured throwing routine in which a player gradually increases throwing distance well beyond normal game distances, then works back down, used to build arm strength and as part of an overall arm-conditioning routine.Baseball
Loop BackswingIntermediateA loop backswing takes the racquet back and up before dropping it down into the forward swing. This uses the circular path to build racquet-head speed and rhythm.Tennis
Loss of Balance on Stretch ShotsIntermediateLoss of balance on stretch shots happens when a wide, low, or hard-hit ball forces a player to reach beyond a stable base. This causes the center of mass to fall away from the shot at contact.Tennis
Loss of PostureIntermediateLoss of posture is any change in spine angle, knee flex, or forward bend from the address position during the swing. This shifts the swing's plane and low point away from where they were originally set.Golf
Lost BallBeginnerA ball is officially lost if it isn't found within three minutes of the group beginning to search for it. This means once that window closes, the golfer must take stroke-and-distance relief, replaying the shot from its original spot plus a one-stroke penalty.Golf
Low Draw ShotAdvancedA low draw shot is a deliberately low-launching, right-to-left curving shot that runs out by a lot on landing. This is useful for navigating under obstacles on the right side of a hole or maximizing roll on firm fairways.Golf
Low PointProLow point is where the clubhead reaches the bottom of its arc through impact. Controlling it — keeping it at or just ahead of the ball with irons — is the basis of pure contact.Golf
Low-Spin MissAdvancedA low-spin miss is a shot with sharply reduced backspin, usually from a thin or low-face strike, that flies with an unstable, hard to predict, "knuckling" trajectory rather than the expected controlled flight.Golf
Lower-Body SlideIntermediateA lower-body slide is excessive lateral movement of the hips toward the target during the downswing, without a matching rotation, that pushes the swing's low point too far forward and leaves the upper body behind.Golf
Lunging (Batting)BeginnerLunging is a timing fault where a hitter commits their weight and stride forward too early. This means usually. At the same time, trying to catch up to velocity or guessing a pitch is coming. This means draining rotational power before the swing even begins.Baseball
Mallet PutterBeginnerA mallet putter uses a larger, often geometric head shape with weight pushed to the perimeter for high forgiveness and, frequently, a face-balanced design suited to a straighter-back-and-through stroke.Golf
Manufacturing RunsIntermediateManufacturing runs is the execution of a sequence of small offensive actions. This means walks, bunts, steals, contact hits, and productive outs. This means that collectively score a run without requiring extra-base power.Fast-Pitch Softball
Match Play vs Stroke PlayBeginnerStroke play scores every shot across the whole round for a cumulative total. Match play scores hole by hole, awarding each hole to whoever takes fewer strokes on it. As a result, a single bad hole only costs one point, not a pile of extra strokes.Golf
Match Tiebreak (10-Point)BeginnerA match tiebreak (or "super tiebreak") is a first-to-10-points breaker, won by two clear points, played instead of a full third set in many doubles and some singles formats.Tennis
Measured ValueBeginnerA measured value is a number that came from a real sensor or instrument. This means a launch monitor, radar gun, or wearable. This means and was not inferred or estimated from video or rules.Analysis Concepts
Mercy RuleBeginnerThe mercy rule is the informal name for the run rule. This means the rule that ends a game early when the scoring gap becomes too large to be competitive, protecting player safety and league scheduling.Slow-Pitch Softball
Middle BallIntermediateA middle ball is a shot aimed directly between two opponents in doubles, designed to create confusion about who should take it and generate communication errors.Pickleball
Middle Infield Bunt CoverageIntermediateMiddle infield bunt coverage is the shortstop and second baseman's job of covering second and third base and backing up throws when the corner infielders and pitcher vacate their positions to field a bunt.Fast-Pitch Softball
Middle Infield CommunicationIntermediateMiddle infield communication is the ongoing verbal and non-verbal coordination between the shortstop and second baseman. This means covering who takes cutoffs, who covers the bag on steals, and who has priority on shallow pop-ups. This means needed to avoid collisions and missed assignments.Slow-Pitch Softball
Mis-Hit CausesBeginnerMis-hit causes fall into a small number of root categories. This means contact-point timing, footwork spacing, balance, and grip mismatch. This means and identifying which one applies is the fastest way to fix repeated mis-hits.Tennis
Mis-Hit Diagnosis (Slow-Pitch)AdvancedMis-hit diagnosis is the process of tracing a weak or poorly directed batted ball back to its specific mechanical cause. This means timing, bat path, contact point, or body position. Instead of treating every bad swing the same way.Slow-Pitch Softball
Mobile Motion CaptureIntermediateMobile motion capture is the process of using a smartphone camera and on-device pose estimation to track body movement in real time or from a recorded clip. This means no specialized hardware required.Analysis Concepts
Mock / Demo DataBeginnerMock or demo data is pre-generated illustrative data used in product demos, onboarding flows, and feature previews. This means always labeled to distinguish it from real user data.Analysis Concepts
Moment of Inertia (MOI)AdvancedMoment of inertia (MOI) measures a clubhead's resistance to twisting on off-center hits. This means a higher MOI keeps the face more stable at impact. This is why perimeter-weighted, forgiving clubs reliably retain more ball speed on mishits.Golf
Momentum Shift in a MatchAdvancedA momentum shift is a noticeable change in which player is controlling the flow of a match, often triggered by a break of serve, a long game won on key points, or a run of consecutive games.Tennis
Moon BallIntermediateA moon ball is a very high, heavily topspun groundstroke hit well above net height to disrupt an opponent's rhythm and buy recovery time without going as high or defensive as a full lob.Tennis
Motion CaptureIntermediateMotion capture records a golfer's body movement in three dimensions, traditionally using reflective markers and multiple cameras, to build a precise digital skeleton of the swing for biomechanical analysis.Golf
Motion LabBeginnerMotion Lab is the browser-based 3D motion analysis tool in SwingVantage that turns your video into a three-dimensional avatar and timeline, letting you rotate, scrub, and measure your swing without any installed software.Analysis Concepts
Motor LearningIntermediateMotor learning is the scientific study of how the nervous system acquires, refines, and retains skilled movement. This means the theory underlying how practice actually changes your swing.Analysis Concepts
Movement PatternIntermediateA movement pattern is the sequence of footwork steps a player uses to reach the ball, execute the shot, and recover to position. This means combining split step, approach steps, stance, and recovery.Tennis
Movement SequencingAdvancedMovement sequencing is the timed order in which body segments accelerate and decelerate through a swing — correct sequencing multiplies speed; incorrect sequencing bleeds it.Analysis Concepts
MulliganBeginnerA mulligan is an informal "do-over". This means hitting a second ball after a poor shot without counting the first one. This means that has no basis in the actual rules of golf and is purely a casual, friendly-round convention.Golf
Muscle MemoryIntermediateMuscle memory is the process by which a motor pattern (the swing) becomes automatic through repetition. This means stored in the motor cortex and cerebellum. As a result, it can be executed without conscious thought.Golf
Narrow StanceBeginnerA narrow stance places the feet closer together than shoulder width, trading some stability for more freedom of hip rotation. This means typically used on shorter shots like chips, pitches, and short irons.Golf
Natural Gut StringAdvancedNatural gut string is made from cow intestine and offers the highest elasticity, best tension retention, and greatest comfort of any string material, at a significant cost and durability trade-off.Tennis
Net Approach TimingIntermediateNet approach timing is when a player moves forward to the net relative to their own shot and the opponent's reply, aiming to split step just as the opponent makes contact.Tennis
Net ControlBeginnerNet control is occupying the forward zone of the padel court as a pair. This means the dominant attacking position from which volleys can be directed down at opponents and overheads can finish points. At the same time, the back pair is limited to defensive shots and lobs.Padel
Net Dominance StrategyIntermediateNet Dominance Strategy is the core tactical framework of padel. This means both players in a pair occupy the net zone, control the point with aggressive volleys and smashes, and use positioning to force opponents into defensive lobs that can be punished.Padel
Net Position Communication (Doubles)IntermediateNet Position Communication is how a padel pair coordinates their side-to-side and depth positioning at the net without necessarily speaking. This means mirroring each other's movement. As a result, the middle and the alleys stay covered as a unit rather than as two individuals.Padel
Net Score vs Gross ScoreBeginnerGross score is the actual number of strokes taken. Net score subtracts a player's course handicap from that total, letting golfers of different skill levels compete on a fair, adjusted basis.Golf
Net ZoneBeginnerThe Net Zone is the dominant attacking position in padel. This means the area closest to the net from which players can volley, smash, and put pressure on opponents without the glass walls being a factor.Padel
Net-to-Back TransitionIntermediateThe Net-to-Back Transition is the movement a pair makes from the attacking net zone to the defensive back position when lobbed. This requires synchronized retreat, correct positioning, and immediate readiness to play off the back glass.Padel
Neutral Ball FlightIntermediateA neutral ball flight is a shot that starts at the target and flies with minimal sideways curve, produced when the clubface angle and swing path are nearly matched at impact.Golf
Neutral GripBeginnerA neutral grip has the lead hand rotated. As a result, 2–2.5 knuckles are visible at address and the trail hand's palm faces the target. This means the "middle" grip position that squares the face without extra hand manipulation.Golf
Neutral Rally BallBeginnerA neutral rally ball is a moderate-pace, high-margin shot hit deep and crosscourt to maintain a rally without taking risk or conceding the point's initiative.Tennis
New BallBeginnerThe new ball is a freshly manufactured cricket ball at the start of an innings (or available after a set number of overs). This swings and seams most readily due to its hard, lacquered surface and prominent seam.Cricket
Nine Ball FlightsIntermediateThe nine ball flights are the classic instructional chart combining three starting directions (left, straight, right) with three curve types (draw, straight, fade/slice) to describe every possible basic shot shape.Golf
No Man's LandBeginnerNo Man's Land is the area of the court behind the kitchen but in front of the baseline where players are most exposed to attacks at their feet and have the least offensive leverage.Pickleball
No-Ad Scoring (Deciding Point)BeginnerNo-ad scoring replaces deuce and advantage with a single deciding point at 40-40, so the next point played wins the game outright.Tennis
No-BallBeginnerA no-ball is an illegal delivery in cricket. This means most commonly when the bowler's front foot lands beyond the popping crease. This means resulting in one extra run and the delivery being re-bowled. The batter cannot be dismissed (except run out).Cricket
No-Stride ApproachIntermediateA no-stride approach keeps the front foot planted throughout the load. This uses hand and hip movement alone to trigger the swing. This means trading a little rhythm and momentum for a simpler, more reliably on-time timing system.Baseball
Non-Volley Zone ViolationBeginnerA non-volley zone violation happens when a player volleys a ball. At the same time, any part of their body, clothing, or paddle touches the kitchen or its line, including from momentum right after the volley.Pickleball
Off-CutterAdvancedThe off-cutter is a pace bowling variation where the ball is cut off the index finger and middle finger to spin towards the off side off the pitch, acting like a slow off-break without a full-length spin action.Cricket
Off-SpinAdvancedOff-spin is a style of finger-spin bowling that turns the ball from off to leg. This means toward a right-handed batter. This means through finger action rather than wrist action, with the off-break as its stock delivery.Cricket
Offset IronsIntermediateOffset irons have the leading edge set back behind the hosel — giving the hands more time to square the face at impact. They are a fitting tool for chronic slicers and high-handicappers.Golf
On DriveIntermediateThe on drive is a classical front-foot attacking stroke played to a full ball on middle or leg stump. This sends the ball through the mid-on region on the leg side.Cricket
On-Base PercentageIntermediateOn-base percentage is the fraction of plate appearances in which a hitter reaches base safely — by hit, walk, or hit-by-pitch. It is the best single-stat predictor of a slow-pitch leadoff hitter's value.Slow-Pitch Softball
On-Base Plus Slugging (OPS)IntermediateOPS is a hitting statistic calculated by adding on-base percentage and slugging percentage together, combining a hitter's ability to reach base with their ability to hit for power into a single number.Baseball
On-Plane SwingAdvancedAn on-plane swing travels along the incoming pitch's flight path through the hitting zone. This keeps the barrel and ball aligned for a longer window and converting timing errors into contact rather than misses.Baseball
One-and-One Count (Slow-Pitch)BeginnerThe one-and-one count is a common slow-pitch rule variation where every at-bat begins with a count of one ball and one strike already applied. Instead of the traditional 0-0 start, shortening the plate appearance to keep recreational games moving.Slow-Pitch Softball
One-Fix PlanBeginnerThe One-Fix Plan is SwingVantage's core methodology. This means identify the single highest-impact fault, build a focused practice plan around fixing only that fault, and confirm the fix with a structured retest before moving on.Analysis Concepts
One-Hand Release FinishIntermediateA one-hand release finish is when the top hand comes off the bat naturally after extension, often associated with a longer, freer swing and additional bat speed for hitters with a strong, well-sequenced rotation.Slow-Pitch Softball
One-Handed BackhandIntermediateA one-handed backhand is struck with only the dominant hand on the grip, offering greater reach and disguise than a two-hander at the cost of stability against high-bouncing pace.Tennis
One-Plane SwingIntermediateA one-plane swing keeps the arms swinging close to the same tilted plane established by the shoulders at address. This produces a flatter-looking backswing with the trail arm folding close to the chest.Golf
One-PuttBeginnerA one-putt is holing out in a single putt once on the green. This means the direct result of either a made long putt or, far more often, a first putt (or approach shot) left close enough to be a near-automatic make.Golf
Open Roster RuleIntermediateAn open roster rule allows a slow-pitch team to substitute defensive players freely and repeatedly throughout the game. This means including re-entering a player who was previously substituted out. Instead of the limited, one-time substitution rules more common in baseball or fast-pitch.Slow-Pitch Softball
Open StanceBeginnerAn open stance aligns the feet, hips, and shoulders left of the target line (for a right-hander), a setup commonly used to hit a fade or to help clear the hips through short-game and bunker shots.Golf
Open StanceIntermediateAn open stance positions both feet roughly parallel to the baseline at contact. This allows the hips to rotate powerfully through the ball without requiring a weight transfer step.Tennis
Open-Stance ForehandIntermediateAn open-stance forehand is hit with the front foot and hips facing the sideline rather than the net. This allows hip rotation to generate power without a full weight transfer forward.Tennis
Opposite Field HittingIntermediateOpposite field hitting is driving the ball to the side of the field away from the hitter's dominant hand. This means it requires letting the pitch travel deeper before contact, and staying disciplined enough not to rush the swing to pull it instead.Baseball
Opposite-Field HittingIntermediateOpposite-field hitting is driving the ball to the field away from the pull side. This means right field for right-handed batters. This means by letting the ball travel deeper into the contact zone before swinging.Slow-Pitch Softball
Out of BoundsBeginnerOut of bounds (OB) is the area outside the course's legal playing boundary, usually marked by white stakes or a fence line. This means hitting a ball there costs stroke and distance, meaning the golfer replays the shot from the original spot plus a one-stroke penalty.Golf
Out of Bounds CallBeginnerAn out-of-bounds call means a ball landed outside the court's sideline or baseline. Any part of the ball touching a boundary line counts as in, not out.Pickleball
Out-SwingIntermediateOut-swing is conventional swing bowling where the ball curves in the air from leg to off (away from the body of a right-handed batter), enticing an edge towards the slip cordon.Cricket
Out-to-InIntermediateAn out-to-in club path means the clubhead is moving left of the target line through impact (for a right-hander). It is the fade, pull, and slice path.Golf
Outfield Arm StrengthIntermediateOutfield arm strength is an outfielder's ability to generate enough throw velocity and carry to reach the infield or plate on a line, directly influencing how aggressively baserunners can take extra bases against that fielder.Slow-Pitch Softball
Outfield DepthIntermediateOutfield depth is how far outfielders play from home plate. Slow-pitch leagues often allow four outfielders; depth is adjusted based on the hitter's power, the score, and the number of outs.Slow-Pitch Softball
Outfield PlayBeginnerOutfield play refers to fielding beyond the inner ring near the boundary, where players must intercept, chase, slide, and throw powerfully to prevent boundaries and effect run-outs.Cricket
Outlier in Swing DataIntermediateAn outlier is a data point that falls far outside the normal range for that metric and session. This means it may represent a genuine extreme swing or a measurement artifact. It requires honest handling before being used in averages.Analysis Concepts
Outside Pitch ApproachIntermediateThe outside pitch approach is the technique for driving an outer-third pitch. This means staying back, extending through the ball deeper in the zone, and using the whole field rather than trying to pull it.Fast-Pitch Softball
Over the TopIntermediateOver the top means the downswing starts by throwing the club outside the backswing plane. This produces an out-to-in path that causes pulls, pull-slices, and loss of distance.Golf
Over-DrawIntermediateAn over-draw is a controlled draw that curves more than intended, usually. This is because the face-to-path gap has widened beyond the amount the golfer normally produces, risking a miss into left-side trouble.Golf
Over-FadeIntermediateAn over-fade is a controlled fade that curves more than intended, effectively crossing over into slice territory, usually. This is because the face-to-path gap has widened beyond the golfer's normal, repeatable amount.Golf
OverheadIntermediateAn overhead is a high-contact smash hit above the head, typically in response to an opponent's lob, aimed at ending the point with pace.Pickleball
Overhead / SmashIntermediateThe overhead (or smash) is a serve-like stroke struck above the head to put away a lob, demanding quick shoulder turn, a trophy-position racquet path, and aggressive pronation through contact.Tennis
Overhead Smash FootworkIntermediateOverhead smash footwork is the pattern of small adjustment steps and a final scissor or step-in motion that positions a player under a lob to hit it with full power and balance.Tennis
Overlapping Grip (Vardon Grip)BeginnerThe overlapping (Vardon) grip rests the trail hand's pinky finger in the groove between the lead hand's index and middle fingers rather than interlocking or fully wrapping around the handle.Golf
Paddle Face AngleBeginnerPaddle face angle is the tilt of the paddle surface at contact. This means open (tilted back) sends the ball upward, closed (tilted forward) sends it downward, and flat produces a straight trajectory.Pickleball
Paddle Ready PositionBeginnerPaddle ready position is the neutral, out-in-front paddle hold used between shots. This keeps the paddle face up and centered. As a result, a player can react equally quickly to either side.Pickleball
Paddle Specification RulesIntermediateSanctioned pickleball play requires a paddle that meets approved size, material, and surface-texture standards, typically drawn from an official approved-paddle list.Pickleball
Padel Scoring SystemBeginnerPadel uses the same point, game, and set structure as tennis. This means 15, 30, 40, game, best of three sets, with a tiebreak at 6 games all. This means with the one common addition of the Golden Point rule replacing traditional deuce-and-advantage at many recreational and some competitive levels.Padel
Parallel ShotBeginnerA Parallel Shot travels straight down the side of the court, close to and parallel with the side glass. This means a more difficult pass attempt than the crosscourt but one that exploits the far sideline and can catch opponents leaning toward the middle.Padel
Partner CommunicationBeginnerPartner communication in doubles pickleball is the ongoing verbal and non-verbal exchange. This means "mine", "yours", "switch", "bounce it". This means that keeps both players coordinated and prevents errors from confusion.Pickleball
Passing ShotIntermediateA passing shot is hit by the baseline player when the opponent has approached the net, aiming to place the ball past the net player through an angle or pace that cannot be volleyed.Tennis
Peel DropAdvancedA peel drop is the standard, fastball-like drop ball. This means the ball peels straight off the fingertips at release, imparting 12-to-6 topspin that makes the ball break sharply and essentially straight down late in flight.Fast-Pitch Softball
Penalty Area (Water Hazard)BeginnerA penalty area. This means commonly a pond, stream, or marked rough. This means is defined by yellow or red stakes/lines and offers relief options (one penalty stroke) that are meaningfully more forgiving than out of bounds, since the ball never technically left the course.Golf
Personal Swing SignatureIntermediateA personal swing signature is the set of repeatable, individual traits. This means tempo, plane, sequencing pattern. This means that stay consistent for a golfer across sessions, distinguishing a genuinely "different" swing from a temporarily flawed one.Golf
Phone Video LimitationsBeginnerPhone video limitations are the practical constraints of recording on a smartphone. This means lens distortion, stabilization artifacts, variable frame rate, and compressed color depth. This means that can reduce analysis accuracy relative to purpose-built cameras.Analysis Concepts
Pick Play (Pitcher Pickoff)AdvancedA pick play uses the pitcher's quick throw toward a base, often set up with a shortstop or second baseman sneaking in behind a runner, to catch an aggressive baserunner leading off too far.Fast-Pitch Softball
Pickoff MoveIntermediateA pickoff move is a pitcher's legal throw (or step) toward a base with a runner on, aimed at catching that runner off the bag before a pitch is thrown.Baseball
Pitch CommandIntermediatePitch command is the ability to reliably place a pitch. This means not just anywhere in the strike zone. But in a precise, intended spot. This means across every pitch type in a pitcher's arsenal.Fast-Pitch Softball
Pitch Count LimitBeginnerA pitch count limit is a maximum number of pitches a player is allowed to throw in a single game or appearance, set by league rules based on age, and typically paired with required rest days before pitching again.Baseball
Pitch Grip VariationsIntermediatePitch grip variations are the different finger placements and seam contacts a pitcher uses on the ball to help produce each pitch type's intended spin, from a four-seam fastball grip to off-center grips for movement pitches.Fast-Pitch Softball
Pitch LocationBeginnerPitch location is where in (or out of) the strike zone the pitcher places the ball. This means the combination of horizontal quadrant and vertical height that makes a pitch effective or hittable.Fast-Pitch Softball
Pitch MixIntermediateA pitcher's pitch mix is the combination and proportion of pitch types thrown. This means for example 55% fastball, 20% slider, 15% changeup, 10% curveball. This means and how that mix shifts by count and batter.Baseball
Pitch RecognitionIntermediatePitch recognition is identifying a pitch's type and location early. This means out of the pitcher's hand and from spin. This means. As a result, the hitter can commit to a swing or take decision before it's too late to act.Baseball
Pitch Recognition (Fast-Pitch)IntermediatePitch recognition is the umbrella skill of identifying pitch type, spin, and speed early enough in flight to make an appropriate swing decision, combining release-point reading, spin reading, and speed-change adjustment into one applied skill.Fast-Pitch Softball
Pitch SequencingAdvancedPitch sequencing is the art of ordering pitches to exploit a hitter's tendencies and set up future offerings. This means making each pitch more effective. This is because of what came before.Baseball
Pitch SequencingAdvancedPitch sequencing is the deliberate ordering of pitches across an at-bat. This means using pitch type, speed, location, and movement to set up and exploit a hitter's reactions.Fast-Pitch Softball
Pitch SpeedBeginnerPitch speed in slow-pitch softball is how fast the ball travels from the pitcher to the plate, typically 25–35 mph. Many leagues impose a maximum speed limit to maintain the recreational character of the game.Slow-Pitch Softball
Pitch SpinIntermediatePitch spin refers to rotation imparted on the ball at release. Intentional spin to alter the ball's flight path is an illegal pitch in slow-pitch; minimal, incidental backspin is generally permitted.Slow-Pitch Softball
Pitch TrackingBeginnerPitch tracking is visually following the slow-pitch ball's entire arc from the pitcher's hand through its peak and all the way down to the contact point. This means the fundamental skill that controls timing against a steeply descending ball.Slow-Pitch Softball
Pitch TunnelingAdvancedPitch tunneling is the strategy of throwing different pitch types that share the same flight path early before diverging late. This means making it nearly impossible for the hitter to distinguish them in time.Baseball
Pitch TunnelingAdvancedPitch tunneling is the principle of releasing multiple pitch types through the same visual "tunnel" early in flight. As a result, they look identical until they diverge near the plate, too late for the hitter to adjust.Fast-Pitch Softball
Pitch VelocityBeginnerPitch velocity is the speed of the ball at release, measured in miles per hour. This means the most commonly cited indicator of pitching power and arm strength.Baseball
Pitcher's Fielding PracticeIntermediatePitcher's fielding practice (PFP) is a dedicated drill set training pitchers to execute defensive plays. This means covering first base, fielding bunts, handling comebacker grounders, and backing up bases.Fast-Pitch Softball
Pitcher's Workload ManagementAdvancedA pitcher's workload management is the deliberate tracking and limiting of pitch counts, innings. Rest between outings to reduce overuse injury risk and preserve performance over a season.Fast-Pitch Softball
PitchingIntermediatePitching is a mid-range short-game shot that carries the ball most of the way to the target with a descending blow and controlled spin, typically from 30–100 yards.Golf
Pitching CircleBeginnerThe pitching circle is the eight-foot-radius ring marked around the pitcher's plate. Foot-placement rules attach to the pitcher's plate itself. The circle's main rulebook role is the look-back rule. This means once the pitcher has the ball in the circle, a runner off base must immediately advance or return.Fast-Pitch Softball
Pitching DeceptionAdvancedPitching deception refers to any element of a pitcher's mechanics, grip, or delivery that delays or confuses the hitter's ability to identify the pitch type, speed, or location.Baseball
Pitching DeceptionIntermediatePitching deception is the set of techniques a pitcher uses to disguise pitch type and location. This means including consistent arm speed, same release point, and minimizing tell-tale grips. This means to delay or confuse the hitter's read.Fast-Pitch Softball
Pitching DistanceBeginnerPitching distance is the measured distance from the pitching rubber to home plate. In slow-pitch softball it is commonly 50 feet. Some youth divisions use 46 feet, and USSSA also allows the pitcher to release from up to 6 feet behind the pitcher's plate.Slow-Pitch Softball
Pitching RubberBeginnerThe pitching rubber is the white rubber slab on the pitcher's mound from which the pitcher must begin and complete a legal delivery. Leaving or dragging off the rubber incorrectly results in an illegal pitch.Slow-Pitch Softball
Placeholder DataBeginnerPlaceholder data is a temporary illustrative value shown in a UI before real data is available. This means always explicitly labeled as a placeholder. As a result, it is never mistaken for an actual measurement or estimate.Analysis Concepts
Plate CoverageBeginnerPlate coverage is the hitter's ability to make solid contact on pitches across the entire width of the strike zone. This means inside, middle, and outside. Without giving any quadrant away to the pitcher.Slow-Pitch Softball
Plate DisciplineIntermediatePlate discipline is the ability to distinguish balls from strikes and to swing only at pitches where the hitter can do damage. This means the foundational mental skill of hitting.Baseball
Plate DisciplineIntermediatePlate discipline is the ability to identify pitches outside the strike zone and choose not to swing. This allows the count to work in the hitter's favor or earning a free base.Slow-Pitch Softball
Player Development PlanIntermediateA player development plan is a written, individualized outline of a player's current skill level, specific priorities to work on. A timeline or checkpoints for reassessing progress, rather than an unstructured, generic practice routine.Baseball
Player ProfileBeginnerThe Player Profile is the persistent record of an athlete's sport, skill level, swing history, fault patterns, progress metrics, and linked sessions that SwingVantage uses to personalize every analysis and advice.Analysis Concepts
Players IronsAdvancedPlayers irons use a compact head, thin top line, and modest perimeter weighting to prioritize shot-shaping control and feedback over maximum forgiveness. This means best suited to golfers whose contact is already reliably near the center of the face.Golf
Playing the Ball Off Two WallsAdvancedPlaying the ball off two walls is the footwork and swing adjustment needed to contact a ball that has already changed direction twice off the side and back glass. This means later, more compact positioning than a single-wall read. This is. This is because the ball's final path only becomes clear after the second rebound.Padel
Plumb BobbingAdvancedPlumb bobbing is dangling the putter vertically from the fingers, closing one eye. Using the shaft as a plumb line against the hole to estimate which way a putt breaks. This means a once-popular technique now considered less reliable than modern methods.Golf
PoachIntermediateA poach is a doubles move where one player crosses in front of their partner to volley a ball that was heading to the partner. This means intercepting it to attack with a better angle, more pace, or the element of surprise.Pickleball
Poaching (Doubles)IntermediatePoaching is when the net player in doubles crosses over to intercept a return or rally ball meant for their partner, cutting off the angle and finishing the point at the net.Tennis
Polyester StringIntermediatePolyester string is a stiff, low-elasticity monofilament string that provides superior spin potential and durability but transmits more shock to the arm compared to natural gut or multifilament strings.Tennis
Pop Time (Catcher)AdvancedPop time is the total time from a pitch hitting the catcher's mitt to the ball arriving in the fielder's glove at second base on a stolen-base or steal attempt, measured in seconds.Baseball
Pop-Up (Batting)BeginnerA pop-up is a batted ball with extreme backspin and a very steep launch angle (above 50°) that goes nearly straight up and is almost always caught for an out.Baseball
Pop-Up (Slow-Pitch)BeginnerA pop-up is a weakly hit ball with a very steep launch angle, usually caused by contact well below the ball's center combined with a bat path that is steeper than the pitch's descent angle.Slow-Pitch Softball
Pop-Up Priority CallBeginnerThe pop-up priority call is the pre-agreed rule for who has the right of way on a shallow fly ball that two or more defenders could reach. This means generally the outfielder coming in over an infielder going back, and whoever calls first and loudest overriding both.Slow-Pitch Softball
Popped-Up DriveBeginnerA popped-up drive launches unusually high and short with excessive backspin, the result of face contact above center combined with added dynamic loft at impact. This means a milder, broader relative of the skied drive.Golf
Popping the Ball Up (Common Miss)BeginnerPopping the ball up is a common mistake where a dink, reset. Another option is block rises higher than intended above the net, handing the opponent an easy attacking opportunity.Pickleball
Por TresAdvancedA "por tres" is a smash hit. As a result, the ball bounces on the court, rebounds high off the glass, and exits the enclosure over the three-meter side wall (a por cuatro exits over the four-meter back wall). This means a spectacular, unreturnable winner that is padel's signature finish and the reason aggressive overhead play aims for the glass rather than the open court.Padel
Pose EstimationAdvancedPose estimation is the computer-vision technique of identifying a person's body position, joint by joint, from an ordinary 2D video frame. This means the core technology behind markerless swing analysis apps.Golf
Pose EstimationIntermediatePose estimation is the computer-vision process that detects the positions of major body joints (keypoints) in each video frame. This produces the skeleton that SwingVantage uses to measure angles and movement patterns.Analysis Concepts
Position Flexibility (Recruiting)AdvancedPosition flexibility, in a recruiting context, is a player's demonstrated ability to competently play more than one position. This broadens the range of college rosters where she could realistically fit and contribute.Fast-Pitch Softball
PostureBeginnerPosture in golf is the spine angle at address. This means bending forward from the hips with a straight back. As a result, the arms hang freely under the shoulders and the body can rotate athletically.Golf
Power LeakIntermediateA power leak is any fault that causes energy built up in the backswing to dissipate before it reaches the clubhead. This means examples include early release, reverse pivot, and early extension.Golf
Power SlapAdvancedA power slap is a slapper's full. This drives swing executed. At the same time, moving through the batter's box. This means combining a running start with a complete swing to drive hard ground balls and line drives past a drawn-in infield.Fast-Pitch Softball
Power ZoneIntermediateThe power zone is the area in front of and slightly inside the hitter's body where the bat is traveling fastest and most perpendicular to the pitch. This produces maximum energy transfer at contact.Slow-Pitch Softball
PowerplayBeginnerThe powerplay is a mandatory period of fielding restrictions in limited-overs cricket where only two fielders are allowed outside the inner fielding circle. This creates more scoring opportunities for the batting side.Cricket
Practice PlanBeginnerA practice plan is a structured, time-blocked schedule of drills and tasks designed to address your diagnosed fault with the right repetitions, feedback cues, and retest protocol.Analysis Concepts
Practice SwingBeginnerA practice swing is a rehearsal swing taken without a ball, used to feel tempo, rhythm, or a specific position before actually hitting a shot.Golf
Practice TransferAdvancedPractice transfer is how well improvements made on the range carry over to performance on the course. High transfer practice is variable and game-like; low transfer is repetitive and blocked.Golf
Practice TransferAdvancedPractice transfer is how much a skill learned in a practice environment carries over to real performance. This means the ultimate measure of whether your training actually worked.Analysis Concepts
Pre-Round WarmupBeginnerA pre-round warmup is a structured sequence. This means mobility, short swings building to full speed, then chipping and putting. This means done before the first tee shot to prepare the body and calibrate feel, not to rebuild the swing.Golf
Pre-Shot RoutineBeginnerA pre-shot routine is the consistent sequence of steps. This means reading the shot, visualizing the flight, taking aim, waggling, and committing. This means that a golfer repeats before every shot to ensure focus and consistency under pressure.Golf
Pressure Plate (Training Aid)IntermediateA pressure plate is a training aid that measures how a golfer's weight shifts across the feet during the swing. This gives direct feedback on pressure sequencing that is otherwise invisible without instrumentation.Golf
Pressure PracticeIntermediatePressure practice is deliberately adding real consequences to practice repetitions. This means a score to beat, a bet with a partner, a single-attempt requirement. This means to rehearse performing under the nerves that a golf course actually creates.Golf
Pressure ShiftProPressure shift is the movement of the center of pressure under the feet — measured by force plates — from trail to lead during the swing. Elite players shift pressure earlier and more decisively than amateurs.Golf
Primary vs. Secondary FaultIntermediateThe primary fault is the swing issue with the highest severity and impact on performance; the secondary fault is the most likely co-existing issue.Analysis Concepts
Productive OutIntermediateA productive out is an out that still accomplishes something for the team. This means advancing a runner, scoring a run, or moving a runner into scoring position. Instead of simply ending the at-bat with no benefit.Baseball
Progress TrackingBeginnerProgress tracking is the longitudinal record of how your key metrics change over multiple sessions and retests, displayed as a timeline that shows improvement, plateaus, and regressions.Analysis Concepts
Progress Tracking (Swing)BeginnerProgress tracking is recording and reviewing swing metrics over time. This means not just a single before-and-after. This means to see whether a change is holding steady, still improving, or drifting back toward the old pattern.Golf
Projectable FrameIntermediateA projectable frame is a young player's body type. This means typically tall and lean. This means that scouts believe has room to add strength and size as the player physically matures. This is expected to translate into added power, velocity, or bat speed later.Baseball
Pronation on ServeAdvancedPronation on serve is the natural inward rotation of the forearm just before and through contact. This squares the racquet face to the ball and adds a final burst of racquet-head speed. This means the largest single contributor to that speed is the shoulder's internal rotation.Tennis
Provisional BallBeginnerA provisional ball is a backup shot played immediately when the original might be lost outside a hazard or out of bounds, saving the group from having to walk all the way back to the tee if the first ball genuinely can't be found.Golf
PullIntermediateA pull is a shot that starts left of the target (for a right-hander) and continues straight without significant curve. This means caused by an out-to-in path with a face matching the path direction.Golf
Pull HittingBeginnerPull hitting is driving the ball to the side of the field that matches your dominant hand — left field for a right-handed batter. It produces power but is the easiest tendency for defenses to shift against.Slow-Pitch Softball
Pull ShotIntermediateThe pull shot is a back-foot, cross-bat stroke played to a short-pitched ball, swinging it around to the leg side, typically between mid-wicket and square leg.Cricket
Pull Side HittingIntermediatePull side hitting is driving the ball to the same side of the field as the hitter's dominant hand. This means the natural result of meeting the ball earlier in the swing. The direction that carries the most raw power for most hitters.Baseball
Pull-FadeIntermediateA pull-fade starts left of the target and curves back toward it (or beyond), produced by an out-to-in club path with a clubface that is open relative to that path but closed relative to the target line.Golf
Pull-HookAdvancedA pull-hook starts left of the target and curves even further left, produced by an out-to-in club path combined with a clubface that is closed relative to that path.Golf
Punch ShotIntermediateA punch shot is a low, controlled recovery shot typically hit from trouble. This means under tree branches or out of wind. This means using a shortened swing and a ball position back in the stance to keep the trajectory well under a normal shot height.Golf
Punch VolleyIntermediateA punch volley is a compact, firm volley at the kitchen line that redirects pace back at the opponent with a short, controlled forward thrust of the paddle.Pickleball
PushIntermediateA push is a shot that starts and flies straight to the right (for a right-hander) with no significant curve. This means caused by an in-to-out path with a face matching the path direction.Golf
Push BuntIntermediateA push bunt uses a firmer, more deliberate bat push rather than a soft catch-and-give. This drives the ball past the pitcher into the space between the first and second baseman.Fast-Pitch Softball
Push-DrawIntermediateA push-draw starts right of the target and curves back toward it, produced by an in-to-out club path with a clubface that is closed to that path but still open to the target line.Golf
Push-OffIntermediateA push-off is the explosive first step that follows a split step. This means loading one foot to drive laterally or forward toward the ball with maximum acceleration from a ready position.Pickleball
Push-Off – PitchingIntermediateThe push-off is the initial drive of the pivot foot against the pitching rubber, converting leg power into forward body momentum at the start of the windmill delivery.Fast-Pitch Softball
Push-SliceIntermediateA push-slice starts to the right of target and curves even further right, the result of an in-to-out club path combined with a clubface that is open to that path.Golf
Push-Through DinkIntermediateA push-through dink is a dink executed primarily by pushing the shoulder and arm forward. Instead of using wrist or elbow. This means producing a controlled, repeatable ball flight that is difficult to accelerate rashly.Pickleball
Putter FittingIntermediatePutter fitting matches length, lie angle, loft, and head style (toe-hang versus face-balanced) to a golfer's actual stroke path. This uses a putting-specific launch monitor rather than the general club fitting most golfers already get.Golf
Putter LengthIntermediatePutter length is fit to a golfer's height, arm length, and preferred posture. This means most standard putters run 33 to 35 inches. But a mismatched length forces a compensating posture that changes lie angle and face position at address.Golf
PuttingBeginnerPutting is rolling the ball along the ground toward the hole using a flat-faced club (putter). It accounts for roughly 40% of strokes in a typical round, making it the most impactful single skill in scoring.Golf
Putting Green Speed (Stimpmeter)IntermediateGreen speed, measured with a Stimpmeter and expressed in feet (commonly 8 to 13), tells how far a ball released from a standard ramp rolls on a level part of the green. This means faster greens amplify break and demand lighter stroke speed.Golf
Putting StrokeBeginnerThe putting stroke is the controlled pendulum motion that rolls the ball along the intended line. Good mechanics include a square face at impact, consistent tempo, and path that matches the putter's arc.Golf
Quality At-BatBeginnerA quality at-bat is a plate appearance judged by the process and competitiveness of the at-bat rather than only by the outcome. This means working a long count, hitting the ball hard, advancing a runner, or drawing a walk can all count even if the hitter didn't get a hit.Baseball
Quick HandsIntermediateQuick hands describe a short, direct path from the load position to the ball. This means the compact swing mechanic fast-pitch hitters need to stay on time in a sub-0.5-second reaction window.Fast-Pitch Softball
Quick PitchAdvancedA quick pitch is a pitcher delivering the ball before the batter is set and ready in the box. This means an attempt to catch the hitter off guard that is illegal at most levels of play.Baseball
RA / StiffnessProRA is a racquet's stiffness measured by how much the frame deflects under load. Higher RA (66+) means a stiffer, more powerful but harsher frame; lower RA (under 58) flexes more for feel and arm comfort.Tennis
Racket PreparationBeginnerRacket Preparation is the early rotation of the shoulders and positioning of the racket head before the ball arrives. This means the first technical movement of any padel groundstroke and a prerequisite for consistent, balanced shot-making.Padel
Racquet DropAdvancedThe racquet drop is the passive falling of the racquet head below the wrist after the unit turn. This creates the low position from which an accelerating, low-to-high swing whips topspin onto the ball.Tennis
Racquet Face Angle at ContactIntermediateRacquet face angle at contact is the tilt of the string bed relative to vertical at the instant the ball is struck. It is the primary factor determining the ball's launch direction and spin type.Tennis
Racquet Head SpeedIntermediateRacquet head speed is how fast the racquet head is traveling at the moment of contact. It is the single largest determinant of ball pace and spin on a given stroke.Tennis
Rally LengthBeginnerRally length is the number of shots in a point from serve to finish, a tactical metric that reveals whether a player wins most points early (0–4 shots), in mid-length rallies (5–8), or in extended exchanges (9+).Tennis
Rally OffenseIntermediateRally offense is a team approach of stringing hits together to score multiple runs in a single inning. This means the primary scoring method when home-run limits are in play.Slow-Pitch Softball
Rally Scoring vs Side-Out ScoringIntermediateSide-out scoring only awards a point to the serving team. At the same time, rally scoring awards a point to whichever team wins the rally regardless of who served. This means both formats exist in pickleball depending on the event.Pickleball
Rally ToleranceIntermediateRally tolerance is a player's ability and willingness to sustain longer point exchanges without forcing a low-percentage shot, reflected in average rally length and shot patience under pressure.Tennis
Random PracticeIntermediateRandom practice varies the club, target, and shot type from one swing to the next rather than repeating the same shot. It produces slower apparent progress but better retention and transfer to actual course play.Golf
Random PracticeIntermediateRandom (or variable) practice mixes different skills, shot types, or conditions within a session. This means producing better long-term retention and transfer to real play than blocked repetition.Analysis Concepts
Range FactorAdvancedRange factor is a traditional defensive statistic calculated as putouts plus assists per game (or per nine innings). It is used as a rough proxy for how much ground a fielder covers.Baseball
Range vs. CourseIntermediateThe gap between range performance and on-course performance is one of golf's most common frustrations. Understanding why it exists helps close it through deliberate practice design.Golf
RBI OpportunityBeginnerAn RBI opportunity is any plate appearance with a runner in scoring position (on second or third base) where the hitter has a realistic chance to drive in a run.Baseball
Reaction WindowAdvancedThe reaction window is the fraction of a second a fast-pitch hitter has to read the pitch, decide whether to swing, and start the swing. This means one of the shortest in any sport due to the combination of pitch speed and short pitching distance.Fast-Pitch Softball
Reading a Fly Ball off the ArcIntermediateReading a fly ball off the arc is the outfielder's skill of judging depth, direction, and hang time from the sound and angle of contact against a descending-arc pitch, rather than watching the ball's full flight before moving.Slow-Pitch Softball
Reading a HopIntermediateReading a hop is the skill of judging early where a ground ball's bounce will arrive. This means as a short hop, an in-between hop, or a long hop. This means. As a result, the fielder can adjust footwork and glove angle before it reaches them.Baseball
Reading BreakIntermediateReading break is predicting how much and which direction a putt will curve based on slope. It is a distinct skill from executing the putting stroke. This means a well-struck putt on a misread line still misses.Golf
Reading Pitch HeightBeginnerReading pitch height is identifying how high a specific delivery will peak. This means low legal, mid-range, or high. This means early enough to set both timing and bat path before the ball reaches the hitting zone.Slow-Pitch Softball
Reading Spin Out of the HandAdvancedReading spin out of the hand is a hitter's ability to identify a pitch's spin direction in the very first fraction of its flight, before the resulting break is visually obvious. This gives extra reaction time against movement pitches.Fast-Pitch Softball
Reading the Ball off the BatAdvancedReading the ball off the bat means recognizing a batted ball's trajectory, speed, and likely landing spot in the split-second after contact. This uses bat angle and initial ball flight rather than waiting to track its full arc.Baseball
Reading the Bunt DefenseIntermediateReading the bunt defense means identifying, before the pitch, how the corner infielders and pitcher are positioned to field a bunt, and using that read to decide bunt type and placement.Fast-Pitch Softball
Reading the PitcherAdvancedReading the pitcher is the baserunner's ability to pick up timing cues in the pitcher's delivery. This means arm position, release tempo, or body tilt. This means to optimize their lead and steal timing.Fast-Pitch Softball
Ready Golf (Pace of Play)Beginner"Ready golf" means playing shots in whichever order gets the group moving fastest. This means whoever is ready hits, rather than strictly waiting for the golfer farthest from the hole. This means a widely encouraged practice in casual and recreational rounds to keep pace of play reasonable.Golf
Ready Position (Slow-Pitch Fielding)BeginnerReady position is the balanced, athletic stance a fielder takes just before the pitch. This means knees bent, weight on the balls of the feet, glove down and out in front. This means that allows an immediate first-step reaction in any direction.Slow-Pitch Softball
Real / Live DataBeginnerReal / Live data is data captured from an actual user session or sensor. This means not a placeholder, not a demo, not a mock. This means and is labeled accordingly. As a result, you can trust it as genuine input to analysis.Analysis Concepts
Rebound AngleIntermediateRebound Angle describes the direction a ball takes after striking a padel glass wall. This is influenced by the angle of entry, the ball's spin. The speed of impact.Padel
Recognizing a Drop Ball EarlyAdvancedRecognizing a drop ball early means identifying the pitch's topspin pattern and slightly higher release angle before its late downward break, letting the hitter adjust the bat path down rather than rolling over the top of the ball.Fast-Pitch Softball
Recognizing a Riseball EarlyAdvancedRecognizing a riseball early means identifying that a rise ball is coming from its low release angle and initial spin pattern before it begins its late upward-relative break. This allows the hitter to lay off pitches climbing out of the zone.Fast-Pitch Softball
Recommendation EngineIntermediateThe advice engine ranks possible fixes by impact and confidence so you get one high-leverage priority fix — not twenty competing tips.Analysis Concepts
Recovery PositionBeginnerRecovery position is the balanced, paddle-ready stance a player returns to after every shot. This means feet shoulder-width apart, knees bent, paddle up, eyes on the opponent. This means before the next shot arrives.Pickleball
Recovery SessionIntermediateA recovery session is a low-intensity practice day focused on reinforcing patterns at slow speed, flushing fatigue, and keeping motor grooves active without accumulating more load.Analysis Concepts
Recovery ShotIntermediateA recovery shot is played from trouble. This means deep rough, trees, a bad lie, or an awkward stance. This means with the primary goal of getting back into a playable position, not necessarily advancing the ball the maximum possible distance.Golf
Recovery StepIntermediateThe recovery step is the movement made immediately after hitting a shot to reposition at the optimal defensive or offensive base before the opponent's next ball.Tennis
Recovery StepIntermediateThe Recovery Step is the movement a player makes immediately after striking the ball to return to a tactically correct base position. This means the net zone, the centre of the baseline, or a partner-synchronized position. This means before the next shot arrives.Padel
Recovery to Center CourtIntermediateRecovery to center court is the movement back toward a balanced base position after hitting a shot, positioned to cover the widest possible range of the opponent's likely replies.Tennis
Recreational League EtiquetteBeginnerRecreational league etiquette is the set of unwritten, participation-first norms that keep casual slow-pitch softball enjoyable. This means things like not running up the score against a clearly overmatched opponent, rotating playing time fairly, and treating umpires and opposing players with respect regardless of the call.Slow-Pitch Softball
Recruiting Video (Skills Video)IntermediateA recruiting video, or skills video, is a short, structured video showing a player's core skills. This means hitting, fielding, throwing, running, and position-specific work. This means used to introduce her to college coaches who have not seen her play in person.Fast-Pitch Softball
RegrippingBeginnerRegripping. This means replacing worn grips, typically every 40 to 80 rounds or once a year for regular players. This means restores traction and feel that gradually degrade as rubber hardens and surface texture wears smooth.Golf
Relay ThrowIntermediateA relay throw is an outfield throw caught by an infielder (the relay man) positioned in a direct line to the target base, who then re-throws it, rather than one long throw all the way from the outfield.Baseball
Relay ThrowIntermediateA relay throw is a ball thrown from an outfielder to a cutoff man who immediately re-throws it to a base. This means used when the distance is too great for one throw to be accurate and powerful.Slow-Pitch Softball
ReleaseIntermediateThe release is the natural unhinging of the wrists and rotation of the forearms through impact that squares the clubface and delivers maximum speed.Golf
Release PointIntermediateRelease point is the precise spatial location in front of the body where the pitcher lets go of the ball. This means consistency here is the foundation of command.Baseball
Release Point – Fast-PitchIntermediateThe release point is the exact moment and location. This means typically near the hip as the arm passes the bottom of the windmill circle. This means where the ball leaves the pitcher's hand, determining both the pitch's initial trajectory and its spin.Fast-Pitch Softball
Repeatable SwingBeginnerA repeatable swing is one that produces a similar result swing after swing, even if the mechanics are not textbook-perfect. This means consistency of outcome matters more for scoring than technical beauty.Golf
ResetIntermediateA reset is a soft, absorbing shot that takes pace off a hard-driven ball and returns it into the opponent's kitchen, neutralizing an attack and restoring a neutral dinking rally.Pickleball
Reset MechanicsIntermediateReset mechanics are the specific technique elements. This means soft hands, open paddle face, forward body position, and minimal backswing. This means that convert a hard-incoming ball into an unattackable kitchen drop.Pickleball
Reset Shot Height ControlIntermediateReset shot height control is the ability to absorb the pace of a hard incoming ball and drop it just over the net into the kitchen. This involves converting a defensive situation into a neutral one.Pickleball
RetestBeginnerA retest is a short follow-up protocol attached to each advice. This means how many shots. This metrics, and what counts as success. This means that confirms whether a fix actually worked.Analysis Concepts
Retest ComparisonIntermediateA retest comparison is a follow-up swing recording measured directly against an earlier baseline swing to check whether a specific, targeted change actually happened.Golf
Retest DeltaIntermediateA retest delta is the change between a pre-drill baseline and the post-drill retest measurement for the same specific metric targeted by that session's fix. This means the short-cycle confirmation of whether a single training session moved the needle.Analysis Concepts
Return DepthIntermediateReturn depth refers to hitting the serve return deep, near the opponent's baseline. This limits their ability to approach the kitchen line comfortably before the third shot.Pickleball
Return DepthIntermediateReturn Depth is how close to the serving pair's baseline the return of serve lands. This means a deep return buys the receiving team time to organise their own net approach. At the same time, a shallow return gifts the servers an easy first volley.Padel
Return of Serve PositioningIntermediateReturn of serve positioning is where a returner stands before the serve. This means how far behind the baseline and how far side to side. This means set to counter the server's pace, spin, and typical patterns.Tennis
Return of Serve PositioningIntermediateReturn of Serve Positioning is where the receiver stands before the serve. This means typically a step or two behind the service line, near the middle of their own service box. This means to balance reaction time against the serving pair against the ability to get a controlled shot back in play.Padel
Return PositioningIntermediateReturn positioning is where a player stands to receive serve. This means generally a step or two behind the baseline, centered enough to cover both angles. This means and where they move to immediately after hitting the return.Pickleball
Return to BaseBeginnerReturning to base is the baserunner's ability to retreat back to their original base quickly when the ball is not put in play, avoiding a pickoff or tag-out after their lead.Fast-Pitch Softball
Reverse PivotIntermediateA reverse pivot is weight moving toward the lead side during the backswing instead of the trail side. This leaves the golfer with nowhere effective to shift on the downswing.Golf
Reverse Spine AngleAdvancedA reverse spine angle is excessive backward spine tilt toward the target at the top of the backswing. This places the upper body in a position that is difficult to unwind safely and reliably on the downswing.Golf
Reverse SweepAdvancedThe reverse sweep is an attacking stroke where the batter kneels on the front knee and sweeps the ball to the off side. This means the mirror image of the conventional sweep, played in the opposite direction.Cricket
Reverse SwingAdvancedReverse swing is a phenomenon where an old, asymmetrically worn ball swings in the opposite direction to conventional swing, deceiving batters conditioned to expect conventional movement.Cricket
Reverse Weight ShiftIntermediateA reverse weight shift is a whole-swing pattern in which pressure moves toward the target during the backswing and then moves away from the target during the downswing. This means the exact opposite of an efficient swing's weight transfer.Golf
Rise BallIntermediateA rise ball is a fast-pitch pitch thrown with backspin that causes it to flatten or climb late in its path, arriving higher than expected and causing hitters to swing under it.Fast-Pitch Softball
Riseball SpinAdvancedRiseball spin is the pure backspin. This means roughly a 6-to-12 spin direction. This means that a pitcher imparts at release to make the ball appear to rise as it nears the plate, the aerodynamic mechanism behind the rise ball.Fast-Pitch Softball
Roll ShotAdvancedA roll shot is a groundstroke or mid-court shot hit with heavy topspin. As a result, the ball dips sharply into the opponent's feet as they advance. This prevents a clean reset.Pickleball
Roll VolleyAdvancedA roll volley is a topspin-imparting volley hit at the kitchen line that dips sharply at the opponent's feet, making it difficult to reset.Pickleball
Rolling OverIntermediateRolling over is a swing fault where the top hand rotates over the bottom hand too early, closing the barrel through contact and producing weak grounders to the pull side.Baseball
Rolling the Wrists (Slow-Pitch)IntermediateRolling the wrists is the top hand turning over the bottom hand before or at contact rather than after extension, the direct mechanical cause behind most rollover ground balls.Slow-Pitch Softball
Rollover (Slow-Pitch)BeginnerA rollover is a weakly hit ground ball, usually to the pull side. It is caused by the hitter's top hand and wrists turning over the bottom hand before or at contact instead of after extension.Slow-Pitch Softball
Root Cause vs SymptomIntermediateA root cause is the underlying issue that creates a swing fault. A symptom is the visible downstream result. This means confusing the two leads golfers to practice fixing the wrong thing.Golf
Rotational HittingIntermediateRotational hitting is a swing model where power comes primarily from the rotation of the hips and torso rather than forward body weight transfer. It is the dominant power model in modern baseball.Baseball
Rotational PowerIntermediateRotational power is the energy generated by rotating the hips and torso into the swing, transferring ground-force and core energy through the arms and into the barrel.Slow-Pitch Softball
Rules EngineIntermediateThe rules engine is the configuration-driven core that checks your shot data and symptoms against sport-specific target windows to identify the best-fitting pattern.Analysis Concepts
RuloAdvancedA rulo is an overhead smash hit with heavy topspin instead of a flat or sliced strike. This produces a ball that clears the net with margin and then kicks forward hard and low after the bounce. This means a safer alternative to a flat smash when the lob sits up but a clean por tres angle to the glass isn't available.Padel
Run OutBeginnerA run out occurs when a fielder hits the stumps with the ball. At the same time, a batter is outside their crease. At the same time, attempting a run. This results in the batter being dismissed.Cricket
Run RuleBeginnerThe run rule (also called the mercy rule) ends a game early when one team leads by a set number of runs after a minimum number of innings. This means typically 15 runs after 3 innings or 10 runs after 5 innings.Slow-Pitch Softball
Running SlapAdvancedA running slap is a full-speed slap approach in which the hitter is already moving toward first base at contact, converting the swing into the first strides of a sprint.Fast-Pitch Softball
Rushing the Split StepIntermediateRushing the split step means landing from the small hop too early, before the opponent has actually struck the ball. This leaves the player flat-footed and unable to react to the true direction of the shot.Tennis
Rushing the SwingBeginnerRushing the swing is starting the load and swing mechanics faster than the pitch actually requires, usually out of anxiety or a habit from a quicker pitch speed. This results in early, off-balance contact.Slow-Pitch Softball
Sacrifice BuntBeginnerA sacrifice bunt trades the batter's own out to advance a baserunner into scoring position. This uses the bunt purely as a situational strategy rather than an attempt to reach base safely.Baseball
Sacrifice BuntBeginnerA sacrifice bunt is intentionally tapping the ball softly into play to advance a baserunner, trading the batter's out for a runner moving into scoring position.Fast-Pitch Softball
Sacrifice FlyBeginnerA sacrifice fly is a fly ball out, hit deep enough to the outfield, that allows a runner on third base to tag up and score after the catch. This means it does not count as an official at-bat and does not hurt the hitter's batting average.Baseball
Sample SizeIntermediateSample size is how many swings or shots a metric is based on. This means small samples produce more noise and lower confidence. Larger samples produce more reliable estimates.Analysis Concepts
Sand SaveIntermediateA sand save is getting up-and-down in particular from a greenside bunker. This means one bunker shot followed by one putt. This means a narrower, harder version of the general up-and-down statistic used to judge bunker play in particular.Golf
Sand WedgeBeginnerThe sand wedge, typically 54° to 58° of loft with generous bounce, is designed in particular for bunker shots and short, high greenside shots. This means its wide, high-bounce sole is what keeps it from digging into sand.Golf
ScoopingBeginnerScooping is the instinct to "help the ball up" by flipping the wrists upward at impact. This means it adds loft, reduces compression, and produces weak, high, short contact.Golf
Scouting Report (Player)IntermediateA scouting report is a written evaluation of a player that grades their tools, describes their present skill level and physical projection, and gives an overall opinion of their future outlook.Baseball
ScramblingIntermediateScrambling percentage measures how often a golfer saves par or better after missing the green in regulation, in any number of strokes. This means the broadest short-game statistic, capturing recovery ability rather than one specific shot type.Golf
Scratch GolferAdvancedA scratch golfer is one with a Handicap Index of 0.0. This means someone who, on an average day, is expected to shoot right around the course rating, a benchmark reached by only a small fraction of golfers.Golf
ScrewballAdvancedA screwball is a fast-pitch pitch that breaks in the opposite direction of a curveball. This means moving in on same-side hitters. This means generated by an outward wrist twist at release, the hand turning away from the body.Fast-Pitch Softball
Screwball Spin DirectionAdvancedScrewball spin direction is the outward wrist rotation at release. This means the hand screwing away from the body, pinky leading. This means that produces a vertical-axis spin opposite to the curveball, breaking the pitch in toward a same-handed hitter rather than away.Fast-Pitch Softball
Seam BowlingIntermediateSeam bowling is a style of pace bowling where the ball is gripped. As a result, the seam is upright and the ball lands on the seam. This causes it to deviate unpredictably off the pitch.Cricket
Seam-Shifted Wake (SSW)ProSeam-Shifted Wake is an aerodynamic effect where an off-center seam orientation disrupts airflow asymmetrically. This produces movement that cannot be predicted from spin rate or axis alone.Baseball
Second ServeIntermediateThe second serve is the follow-up attempt after a fault. This requires enough spin and margin to give the serve a wide safety margin. At the same time, still limiting the returner's options.Tennis
Second ServeBeginnerThe Second Serve in padel is the backup serve used after a first-serve fault. This means typically hit with more spin, less pace, and more margin to improve the chance it lands in the box. At the same time, still creating difficulty for the receiver.Padel
Second Serve SpinIntermediateSecond serve spin is the extra topspin or kick a server adds on the second delivery to raise net clearance and margin for error after a missed first serve.Tennis
Secondary LeadIntermediateThe secondary lead is the movement a baserunner takes as the pitch crosses the plate. This means a walking step or shuffle that adds momentum toward the next base the moment contact is made.Baseball
Self-DiagnosisBeginnerSelf-diagnosis is a golfer trying to identify the cause of their own swing fault without outside feedback. This is prone to error. This is because feel is an unreliable guide to what the body is actually doing.Golf
Semi-Continental Grip (Volley)BeginnerThe semi-continental grip sits between a full continental and eastern forehand grip, used by some players at net to balance quick forehand and backhand volley transitions without a grip change.Tennis
Semi-Western GripBeginnerThe semi-western grip (base knuckle on bevel 4) is the most popular modern forehand grip, balancing topspin capability with comfortable contact across a wide range of ball heights.Tennis
SeparationProSeparation in the golf swing is when body segments rotate at different rates at different times. This means most importantly when the hips lead the shoulders at the start of the downswing. This creates torque.Golf
ServeBeginnerThe pickleball serve is an underhand stroke hit diagonally into the opposite service box, with contact below the waist and an upward arc. Under the two-bounce rule the serving team cannot follow the serve to the net, making depth and placement — not pace — its most important qualities.Pickleball
ServeBeginnerThe padel serve is an underarm delivery. This means the ball is bounced once and struck at or below waist height into the diagonal service box. This means making placement and net advancement far more important than pace.Padel
Serve and Net StrategyIntermediateServe and Net Strategy in padel means the serving pair immediately rushes to the net zone after the serve, arriving before the return. As a result, they control the net advantage from the very first rally exchange.Padel
Serve and VolleyAdvancedServe and volley is a tactical pattern in which the server rushes to the net immediately after delivering the serve, intending to end the point with a first or second volley.Tennis
Serve and VolleyIntermediateServe and Volley in padel is the specific tactic of the server immediately sprinting to the net zone after delivering the serve to arrive in the volley position before the receiver can lob effectively.Padel
Serve Motion LegalityBeginnerA serve is legal only if contact happens at or below waist height and the paddle head stays below the level of the serving wrist at the moment of contact.Pickleball
Serve PlacementIntermediateServe placement is the deliberate targeting of a specific zone in the opponent's service court — deep backhand, body, or wide — to create a weaker return.Pickleball
Serve PlacementIntermediateServe Placement in padel is the deliberate targeting of specific zones within the service box. This means the T, the wide corner, or the body. This means to create the weakest possible return and set up an easy net volley.Padel
Serve Rotation (Doubles)BeginnerIn doubles, a team keeps serving with each partner taking a turn as the server, switching service courts after every point won, until the team faults and the serve passes to the opponents.Pickleball
Serve RoutineBeginnerA serve routine is the consistent pre-serve sequence. This means bouncing the ball, breathing, positioning the feet. This means that helps players enter a calm, focused state before every delivery.Tennis
Serve Toss PlacementBeginnerServe toss placement is where the ball is released relative to the body. It determines which serve types are physically possible to hit from that toss.Tennis
Serve-Plus-One PatternIntermediateServe-plus-one is a tactical pattern where the server plans the first shot after the serve before the point starts. This uses the serve to set up a predictable, attackable ball.Tennis
Server Number (1 or 2)BeginnerThe server number identifies which of the two partners on a doubles team is currently serving, and is called out as the third number in the score. This means for example, "4-3-2" means the team's second server is serving.Pickleball
Service BoxBeginnerThe Service Box is the rectangular area diagonally opposite the server into which the underarm padel serve must land after one bounce. This means with pace blunted by the walls, placement beats power. This makes slice and kick serves especially effective.Padel
Setup RoutineBeginnerA setup routine is the repeatable sequence of steps. This means aim the face, align the body, take the grip, waggle, go. This means that builds consistent, pressure-proof address positions.Golf
SeverityIntermediateSeverity is how significant a swing fault is expected to be for performance, labeled Critical, High, Moderate, or Low.Analysis Concepts
Shaft FlexIntermediateShaft flex describes how much a shaft bends during the swing. Ratings run from L (Ladies) through A (Senior), R (Regular), S (Stiff), to X (Extra Stiff) — matched to swing speed for optimal launch.Golf
Shaft LeanIntermediateShaft lean is when the grip end of the club is ahead of the clubhead at impact — the hands in front of the ball. It reduces dynamic loft, compresses the ball, and is the signature of good iron contact.Golf
Shaft WeightIntermediateShaft weight, measured in grams, influences both swing speed and control. This means lighter shafts generally allow faster swing speeds. At the same time, heavier shafts often improve tempo consistency and control for faster swingers.Golf
Shake and BakeAdvancedShake and bake is a doubles strategy where one partner drives the third shot hard. At the same time, the other charges the kitchen line, ready to poach and put away any weak block the opponents return.Pickleball
Shallow DownswingIntermediateA shallow downswing describes a club delivery angle that has flattened too much relative to what a golfer's setup and swing plane call for. This can produce blocks, hooks, or thin contact when it goes beyond a useful amount.Golf
ShallowingAdvancedShallowing is when the club shaft flattens (becomes more horizontal) in the early downswing. This allows it to approach the ball from inside the target line for a powerful, in-to-out delivery.Golf
ShankIntermediateA shank is when the ball strikes the hosel (the socket where the shaft meets the head) instead of the face. This sends it violently to the right (for a right-hander) at roughly 45°.Golf
Shank PatternAdvancedA shank pattern is a recurring, structural tendency to strike the ball off the hosel, distinct from an isolated cold shank, usually traced to a consistent setup or swing-path cause.Golf
Shanking the Ball (Tennis)BeginnerA shank happens when the ball contacts the racquet near the throat or the edge of the frame instead of the string bed. This sends it off in an hard to predict, often sharply angled direction.Tennis
Short Backswing CompensationIntermediateShort backswing compensation is when a player shortens the backswing under time pressure to force contact, sacrificing racquet-head speed and stored energy to keep the swing "on time."Tennis
Short Fielder (Rover)BeginnerThe short fielder, or rover, is slow-pitch softball's 10th defensive player. This means a fourth outfielder (or extra infielder, depending on the defense) who fills the gaps a descending-arc pitch tends to produce.Slow-Pitch Softball
Short GameBeginnerThe short game is all shots played around and on the green. This means putting, chipping, pitching, and bunker play. This means and typically accounts for 60–65% of strokes in an average round.Golf
Short GameBeginnerThe short game is fast-pitch's collection of low-power, high-pressure offensive tactics. This means bunts, slaps, and push bunts. This means used to move runners and beat defenses with speed rather than power.Fast-Pitch Softball
Short HopIntermediateA short hop is fielding a ground ball immediately after it bounces, catching it just as it leaves the dirt. This means often considered the cleanest hop to field. This is because the ball is rising predictably.Baseball
Short Hop PickupIntermediateA short hop pickup is fielding a ground ball the instant after it bounces, catching it low and out in front with soft hands rather than waiting for it to rise to a more comfortable height.Slow-Pitch Softball
Shot SelectionIntermediateShot selection is the real-time tactical decision of which shot type, direction, pace, and spin to use on each ball, based on court position, ball height, opponent location, and score situation.Tennis
Shot Selection at the KitchenIntermediateShot selection at the kitchen is the ongoing decision, ball by ball, between dinking, resetting, speeding up, or lobbing. This means based on ball height, opponent position, and score situation rather than habit.Pickleball
Shot Selection Under Pressure (Padel)AdvancedShot Selection Under Pressure is choosing the safer, higher-percentage shot at important or high-tension moments in a point or match. This means a controlled lob or a solid block instead of a low-margin winner. Instead of letting nerves push the choice toward unnecessary risk.Padel
Shoulder TurnIntermediateShoulder turn is the rotation of the thoracic spine and shoulders during the backswing. A full shoulder turn (near 90°) is the primary source of swing arc and coil — the engine of a powerful backswing.Golf
Showcase Camp (Fast-Pitch)IntermediateA showcase camp is an in-person event where fast-pitch softball players perform standardized skills testing and often scrimmage in front of college coaches. This gives coaches direct, comparable evaluation of many players at once.Fast-Pitch Softball
Showcase EventIntermediateA showcase event is an organized gathering where players perform standardized drills and tests. This means such as 60-yard dash times, throwing velocity, exit velocity, and pitching velocity. This means in front of college recruiters or pro scouts, rather than in the context of a regular game.Baseball
Shuffle StepBeginnerA shuffle step is a lateral movement pattern where the feet slide sideways without crossing. This keeps the player balanced and facing the net during kitchen-line exchanges.Pickleball
Side GlassBeginnerThe Side Glass is the lateral transparent wall running alongside each half of a padel court. This redirects angled shots back into play and creates unique rebound trajectories not seen in any other net-divided racket sport.Padel
Side OutBeginnerA side out is the moment the serve passes from one team to the other. This happens under side-out scoring when the serving team has no server left in its rotation who has not yet faulted.Pickleball
Side-by-Side FormationBeginnerSide-by-side formation is the standard doubles alignment where both partners stand level with each other. This means either at the kitchen line or the baseline. This means dividing court coverage left and right.Pickleball
Sidestep / ShuffleBeginnerA sidestep or shuffle keeps the player facing the net. At the same time, moving laterally, maintaining balance and readiness to load for a groundstroke without crossing the feet.Tennis
Signal vs NoiseIntermediateSignal is the real, repeatable pattern in your swing data; noise is the random variation that looks like a pattern but isn't. Distinguishing the two is what separates useful analysis from false precision.Analysis Concepts
Single-Digit HandicapAdvancedA single-digit handicap. This means a Handicap Index between 0.0 and 9.9. This means identifies a genuinely accomplished amateur golfer, typically representing well under 10% of golfers who track an official handicap.Golf
Situational HittingIntermediateSituational hitting is adjusting a hitter's approach. This means swing decision, target location, and aggressiveness. This means to match the specific game situation, such as the count, number of outs, and where runners are, rather than swinging the same way in every at-bat.Baseball
Situational HittingIntermediateSituational hitting adjusts the at-bat goal based on game context. This means moving a runner. This drives in a specific base, or avoiding a double play. Instead of always swinging for maximum power.Slow-Pitch Softball
Situational HittingIntermediateSituational hitting is the ability to adjust your offensive approach based on the game situation. This means score, inning, count, runner placement, and number of outs. This means to give your team the best chance to score.Fast-Pitch Softball
Skeletal TrackingAdvancedSkeletal tracking is software that identifies a person's joints and limbs from a video image and connects them into a simplified stick-figure model. This means the technical foundation that lets a single smartphone video estimate body positions throughout a swing.Golf
Skeleton OverlayBeginnerA skeleton overlay is the on-screen visualization of detected body joints and the lines connecting them, drawn over your video. As a result, you can see exactly what the system tracked.Analysis Concepts
Skied DriveBeginnerA skied drive is struck high on the driver face, launching the ball almost straight up with a distinctive scuff mark near the crown, and traveling a fraction of the expected distance.Golf
Skill AcquisitionIntermediateSkill acquisition is the process by which practice and feedback cause a movement pattern to become more automatic, consistent, and robust under pressure. This means the goal of all training.Analysis Concepts
Skill Rating System (Player Ratings)IntermediateA skill rating is a numeric score used to place players into fair divisions for tournaments and organized open play. It is based either on self-assessment or on results from rated matches.Pickleball
Skill TreeBeginnerThe Skill Tree is a visual map of a sport's key technical skills. Organized into an unlockable hierarchy that shows where you stand and what to develop next.Analysis Concepts
Skulled ShotBeginnerA skulled shot is contact made on the equator or upper half of the ball with the leading edge of the club. This sends a low, hot, unintended screamer across the green instead of a controlled chip or pitch.Golf
Slap Approach TimingIntermediateSlap approach timing is the coordination between a slapper's crossover footwork and the pitcher's release point. As a result, the final step and swing land together instead of racing ahead of or lagging behind the pitch.Fast-Pitch Softball
Slap HittingAdvancedSlap hitting is a left-handed offensive technique where a fast runner moves through the batter's box toward the pitcher. At the same time, making contact, converting their running start into a head-start toward first base.Fast-Pitch Softball
SliceBeginnerA slice is a shot that curves sharply away from the target — to the right for a right-handed golfer. It happens when the clubface is open relative to the swing path at impact.Golf
SliceBeginnerIn tennis, a slice is a shot hit with backspin by swinging high-to-low through the ball, producing a low, skidding bounce. (This differs from a golf slice, which is a curving mishit.)Tennis
Slice ServeIntermediateA slice serve applies sidespin by brushing around the outside of the ball. This causes it to curve away from a right-handed server's deuce-side opponent and stay low after the bounce.Tennis
Slice ServeIntermediateA Slice Serve in padel is an underarm serve struck with sidespin. As a result, the ball curves in the air and then skids low and wide off the bounce, drawing the receiver out of position.Padel
SlideBeginnerA slide is the technique a baserunner uses to reach a base below a tag, to stop momentum from overrunning the base, or to avoid a collision.Baseball
SliderIntermediateThe slider is a breaking ball with lateral movement and some downward tilt, faster than a curveball and typically sharper in its late break.Baseball
Sliding TechniqueIntermediateSliding technique is the controlled fall a baserunner executes to reach the base below a tag. This means including the feet-first pop-up slide, the hook slide to avoid a tag. The head-first dive.Fast-Pitch Softball
Slingshot Wind-UpBeginnerThe slingshot wind-up is a simplified fast-pitch delivery in which the pitcher raises the arm straight back to about shoulder height in a single motion, then brings it forward through just one pass of the arm circle before release.Fast-Pitch Softball
Slip CatchingIntermediateSlip catching is the specialist fielding skill of catching edges from the bat in the slip cordon. This means the group of fielders positioned behind the batter on the off side. This means typically requiring exceptional reflexes and soft hands.Cricket
Slog SweepIntermediateThe slog sweep is a powerful, high-risk batting stroke where the batter sweeps a short-pitched or good-length ball over deep mid-wicket, aiming to hit it out of the ground for six.Cricket
Slow BallIntermediateA Slow Ball in padel is a deliberately softly struck shot. This means often with backspin. This means used to change the rhythm of a rally, disrupt a net-zone pair's timing, or draw opponents out of position.Padel
Slow Roller ChargeAdvancedA slow roller charge is an infielder's aggressive sprint toward a weakly hit ground ball, often fielding it bare-handed on the run, to have any chance of throwing out a batter-runner before they reach the base.Slow-Pitch Softball
Slow-Motion ReviewBeginnerSlow-motion review is watching swing footage played back at a fraction of real speed. This lets a golfer or coach see fast-moving positions. This means especially near impact. This means that are impossible to perceive at normal playback speed.Golf
Slow-Pitch Outfield AlignmentIntermediateOutfield alignment in slow pitch is the pre-pitch positioning of the three (or four, with a rover) outfielders based on batter tendency, count, and field dimensions. This means set deeper and wider than fast-pitch or baseball outfields. This is because of the steep descending arc.Slow-Pitch Softball
Slower BallIntermediateThe slower ball is a variation delivery bowled by a pace bowler at by a lot reduced speed. This means usually 20–30 km/h below full pace. This means to deceive a batter expecting the standard pace.Cricket
Small Ball StrategyBeginnerSmall ball strategy is a team offensive philosophy that prioritizes manufacturing single runs through bunts, steals, hit-and-runs, and sacrifice plays rather than waiting for extra-base hits.Fast-Pitch Softball
SmashIntermediateA smash is a powerful overhead hit downward to finish a point. In padel it is often directed at the back glass. As a result, the ball rebounds out of the enclosure entirely for a winner. This means the signature "por tres" or "por cuatro" finish.Padel
Smash FactorIntermediateSmash factor is ball speed divided by club speed — a measure of strike efficiency. A driver smash factor near 1.50 means the ball left the face at 1.5× the clubhead speed, the practical maximum.Golf
Smash from the Back GlassAdvancedA smash from the back glass is the rare, situational overhead a defending player hits when a rebound off the back glass comes up high and slow enough to attack outright. This means an exception to the usual bajada-or-lob response, available only when the incoming ball lacked pace or spin.Padel
Smothered HookAdvancedA smothered hook is a low, hooded shot that never gets airborne, caused by an excessively closed clubface at impact combined with a delofted, shut position through the strike.Golf
Snap HookAdvancedA snap hook is a sudden, sharp left curve that appears late but violently in the ball flight. This typically from a clubface that closes rapidly relative to path in the last moments before impact.Golf
Soft HandsIntermediateSoft hands is the ability to absorb pace from an incoming ball by relaxing the grip slightly at impact, converting a hard shot into a controlled, softly placed return.Pickleball
Speed Control (Putting)IntermediateSpeed control is calibrating stroke length and tempo. As a result, the ball travels the intended distance. This means widely considered the single most important putting skill, since a well-read putt at the wrong speed still misses and often leads to a three-putt.Golf
Speed to First BaseIntermediateSpeed to first base describes how quickly a batter can travel from home plate to first base, most commonly measured as a stopwatch time and used to evaluate bunt, slap, and infield-hit potential.Fast-Pitch Softball
Speed-UpIntermediateA speed-up is an offensive attack launched from the kitchen line during a soft dink exchange. This means a sudden hard drive aimed at the opponent's body or shoulder to force a reflex error before they can reset.Pickleball
Speed-Up DinkAdvancedA speed-up dink is an abrupt increase in pace on a ball that has risen above net height during a dink rally, converting a soft exchange into a firm, attacking shot with minimal backswing.Pickleball
Spin AxisIntermediateSpin axis is the tilt of the ball's backspin axis relative to horizontal. This determines how much of the total spin curves the ball sideways versus keeps it flying straight and high.Golf
Spin AxisAdvancedSpin axis is the imaginary line around which a pitched ball rotates, determining the direction of movement. This means a horizontal axis creates vertical break (rise/drop), a vertical axis creates horizontal break (curve/screwball).Fast-Pitch Softball
Spin LoftProSpin loft is the angle between the dynamic loft of the face and the attack angle at impact. It is the primary driver of spin and a key lever for controlling distance and flight.Golf
Spin RateIntermediateSpin rate is how fast the ball spins after impact, in revolutions per minute. It controls how the ball climbs, holds the air, and stops on landing.Golf
Spin Rate (Pitching)AdvancedSpin rate is how fast the ball rotates in revolutions per minute (RPM) after leaving the hand. This means higher spin amplifies the Magnus effect and increases pitch movement.Baseball
Spine AngleIntermediateSpine angle is the forward tilt of the upper body established at address, created by hinging from the hips. This means maintaining that same tilt throughout the swing is one of the clearest markers of consistent ball-striking.Golf
Spine TiltIntermediateSpine tilt at address is the slight away-from-target lean of the spine. This means especially with a driver. This means that promotes a positive attack angle and lets the trail shoulder drop below the lead shoulder.Golf
Split StepBeginnerA split step is a small hop timed to the moment your opponent strikes the ball. It primes your legs to push off explosively in any direction.Tennis
Split StepBeginnerA split step is a small, timed hop that occurs just as the opponent contacts the ball. This means it loads both feet at the same time and allows instant movement in any direction.Pickleball
Split StepBeginnerThe Split Step is a small two-footed hop taken just as the opponent strikes the ball, loading weight onto both feet at the same time. As a result, the player can push off right away in any direction.Padel
Splitter / ForkballAdvancedThe splitter is an off-speed pitch gripped with the fingers spread across the seams. This produces late diving action that generates weak contact or swings below the zone.Baseball
Splitting the Transition ZoneAdvancedSplitting the transition zone refers to timing a small, balanced hop or pause partway through the advance from baseline to kitchen, right before the opponent's shot, rather than advancing in one continuous run.Pickleball
Sportsmanship RuleBeginnerA sportsmanship rule is a formal league policy. This means distinct from unwritten etiquette. This means that empowers umpires or league officials to eject players, forfeit games, or suspend teams for conduct like arguing calls excessively. This uses abusive language, or unsafe aggressive play, regardless of the game's outcome.Slow-Pitch Softball
Spray AngleIntermediateSpray angle is the horizontal direction the ball travels off the bat. This means pull side, up the middle, or opposite field. This means determined by when in the swing the barrel meets the ball.Baseball
Square CutIntermediateThe square cut is a back-foot, cross-bat stroke played to a short, wide ball outside off stump, slashing it square on the off side toward point.Cricket
Square StanceBeginnerA square stance lines the feet, hips, and shoulders parallel to the target line. This means the neutral reference alignment every open or closed stance is measured against.Golf
Squared-Up RateAdvancedSquared-up rate measures how close a batted ball's exit velocity comes to the maximum possible speed the bat and pitch could theoretically produce on that particular swing. This means a measure of contact-point precision independent of raw bat speed.Baseball
SquatProThe squat is a slight downward drop of the body at the start of the downswing, where the golfer loads into the ground before exploding upward through impact.Golf
Squeeze Bunt (Fast-Pitch)IntermediateA squeeze bunt in fast-pitch is a bunt call with a runner on third, made unusually high-risk by the short 40–43 foot pitching distance that gives the runner, batter, and defense almost no time to react to how the pitch is actually thrown.Fast-Pitch Softball
Squeeze Play (Bunt)AdvancedA squeeze play is a bunt called in particular to score a runner from third base. This means a "suicide squeeze" sends the runner as the pitch is thrown regardless of where the bunt goes. At the same time, a "safety squeeze" holds the runner until the bunt is down.Baseball
Stability vs MobilityIntermediateStability vs mobility is the biomechanical principle that joints alternate between roles. This means some must be stable anchors, others must be mobile movers. This means and faults often come from reversing these roles.Analysis Concepts
Stableford ScoringIntermediateStableford scoring awards points based on how a hole score compares to par (or net par) rather than counting total strokes. This softens the impact of a single disaster hole and keeps a bad hole from ruining an entire round's result.Golf
StackingAdvancedStacking is a doubles strategy where both players position on the same side of the court before the serve or return, then slide to their preferred sides after the ball is in play. This means overriding the score-dictated positions to keep both forehands covering the middle.Pickleball
StanceBeginnerYour stance is how you position your feet, weight, and body at address before the swing. It sets your balance, swing width, and low point.Golf
Steep Bat PathIntermediateA steep bat path angles more sharply downward through the contact zone than the pitch's own descent. This leaves only a tiny contact window. This means contact a fraction early clips under the ball for weak pop-ups. At the same time, contact a fraction late tops it into the ground.Slow-Pitch Softball
Steep DownswingIntermediateA steep downswing is a club delivery angle noticeably more vertical than the backswing plane, typically caused by an upper-body-led transition, and associated with deep divots, pulls, and lost distance.Golf
Stinger ShotAdvancedA stinger is a deliberately low, boring, low-spin shot. This means usually hit with a driver or long iron off the tee. This means that stays under wind and rolls out extra yards on landing, made famous by tour players in windy major championships.Golf
Stolen BaseIntermediateA stolen base is the advancement of a baserunner to the next base on their own initiative during a pitch, relying on a quick jump, reading the pitcher's release, and superior speed over the catcher's pop time.Fast-Pitch Softball
Straight Ball FlightBeginnerA straight ball flight is a shot that shows essentially no sideways curve. This is because the clubface angle and swing path are matched closely enough at impact that the spin axis stays close to horizontal.Golf
Straight BatBeginnerPlaying with a straight bat means swinging the bat vertically, in line with the ball's path. This means the safest, most orthodox technique for defending and driving balls of a full or good length.Cricket
Straight DriveIntermediateThe straight drive is a front-foot attacking stroke played to a full ball on or just outside off stump. This sends the ball back past the bowler straight down the ground.Cricket
Straight-Arm ForehandAdvancedA straight-arm forehand keeps the hitting arm extended through the forward swing rather than bent at the elbow. This uses the longer lever to generate additional racquet-head speed from body rotation.Tennis
Straight-Back BackswingBeginnerA straight-back backswing takes the racquet directly back on a flat, linear path rather than looping up and over, favoring simplicity and timing control over generated racquet-head speed.Tennis
Stride (Batting)BeginnerThe stride is the small forward step or toe-tap the hitter takes to trigger timing. It is a timing mechanism, not a source of power, and must be soft and directional.Baseball
Stride Length – PitchingIntermediateStride length is the distance the pitcher's front foot travels forward from the pitching rubber toward home plate during the delivery. It is one of the clearest visible indicators of how much lower-body drive is contributing to a pitch.Fast-Pitch Softball
Stride TimingIntermediateStride timing is when the front foot lands relative to the pitch's position in its arc. Against slow-pitch arcs, the front foot should land early. This means near the peak. This means. At the same time, the hands stay back. This creates the separation between lower body and upper body that generates power.Slow-Pitch Softball
Strike QualityIntermediateStrike quality is a composite assessment of how solidly and reliably a golfer contacts the ball. This means combining strike location, low-point control, and smash factor. Instead of any single measurement alone.Golf
Strike ZoneBeginnerThe strike zone is the three-dimensional region over home plate, between the batter's knees and the midpoint of the torso, where a pitch must pass to be called a strike.Baseball
Strike Zone – Slow-PitchBeginnerThe slow-pitch strike zone (USA Softball) is the space over home plate between the batter's back shoulder and front knee. A strike is a legal, properly arced pitch that passes through that zone in flight. At the same time, mat-play leagues instead call strikes on pitches that land on the plate or strike mat.Slow-Pitch Softball
Strikeout PitchIntermediateA strikeout pitch is the specific pitch a pitcher goes to in two-strike counts to finish the at-bat. This means their most reliable swing-and-miss weapon given the batter's tendencies.Fast-Pitch Softball
Strikeout RateIntermediateStrikeout rate (K%) is the percentage of plate appearances that end in a strikeout — elevated K% reduces a hitter's value by eliminating batted-ball outcomes entirely.Baseball
String GaugeAdvancedString gauge is the thickness of a tennis string measured in millimetres or gauge numbers, with thinner strings providing more spin and feel and thicker strings offering greater durability.Tennis
String TensionIntermediateString tension is the tightness at which strings are pulled through the racquet frame, measured in pounds or kilograms, influencing the trampoline effect, control, and power of the string bed.Tennis
Strokes GainedAdvancedStrokes gained measures how many strokes a player gains or loses relative to a benchmark (tour average or peer group) on each category of shots. This means off the tee, approach, around the green, and putting.Golf
Strong GripBeginnerA strong grip rotates both hands further to the trail side than neutral. This means 3 or more knuckles visible at address. This means which makes the face easier to close and is a common fix for a chronic slice.Golf
StumpsBeginnerStumps are the three upright wooden posts. This means off stump, middle stump, and leg stump. This means that form each wicket in cricket, topped by two small bails that fall if the ball strikes them.Cricket
Super OverBeginnerThe super over is a tie-breaking mechanism in limited-overs cricket. This means if scores are tied at the end of a match, each team bats one final over of six balls to determine the winner.Cricket
SwayIntermediateA sway is a lateral slide of the hips and upper body away from the target during the backswing, substituting sideways movement for rotation and making a consistent return to the ball difficult.Golf
Sweep ShotAdvancedThe sweep is a cross-bat shot played on one knee to a (usually spinning) good-length ball, sweeping it around to the leg side to counter turn and length.Cricket
Sweeping ContactIntermediateSweeping contact is a shallow, level-to-slightly-descending strike style. This means appropriate for the driver, fairway woods, and hybrids. This means that brushes the turf rather than taking a deep, digging divot.Golf
Sweet SpotBeginnerThe sweet spot is the center of percussion on the clubface. This means the point where a strike produces maximum energy transfer to the ball, felt as minimal vibration and maximum distance.Golf
Sweet Spot Contact (Slow-Pitch)BeginnerSweet spot contact is meeting the ball on the bat's optimal vibration node. This typically several inches from the barrel end, where energy transfer is highest and sting or vibration is lowest.Slow-Pitch Softball
Swing BowlingAdvancedSwing bowling is making a fast-bowled ball curve sideways through the air. This means toward the batter (inswing) or away (outswing). This means by exploiting the pressure difference created when one side of the ball is shinier than the other.Cricket
Swing ConsistencyIntermediateSwing consistency measures how much a golfer's key swing traits. This means tempo, plane, impact position. This means vary from one swing to the next, with lower variability generally correlating with tighter shot dispersion.Golf
Swing DecodeBeginnerSwing Decode is SwingVantage's golf-specific analysis view that breaks the swing into distinct phases. This means address, takeaway, top, downswing, impact, and follow-through. This means and annotates each phase with the relevant mechanics detected.Analysis Concepts
Swing Fault PriorityIntermediateSwing fault priority is the process of deciding which of several visible issues in a swing to address first, since faults are often connected and fixing the right one first can resolve others on its own.Golf
Swing LengthAdvancedSwing length is the total distance the bat's barrel travels from the start of the swing to contact. This means a shorter, more direct path generally means less time is needed to react, at some cost to the maximum bat speed a longer path can generate.Baseball
Swing Overlay ComparisonIntermediateA swing overlay comparison places two swing videos on top of or beside each other, synced to the same reference point (usually impact). As a result, differences between them. This means a baseline versus a retest, or two different swings. This means are visible directly rather than relying on memory.Golf
Swing PathIntermediateSwing path is the trajectory the barrel takes from the load position through contact and into the follow-through. In slow pitch the optimal path is level-to-slight-uppercut to match the ball's steep descent.Slow-Pitch Softball
Swing PlaneIntermediateSwing plane is the tilted circle the club travels on around your body during the swing. A consistent plane makes it easier to return the club squarely and on path at impact.Golf
Swing SequencingAdvancedSwing sequencing is the order and timing in which body segments. This means hips, torso, arms, then club. This means accelerate and peak in speed during the downswing. It is the biomechanical signature that separates efficient power transfer from a swing that looks fast but isn't.Golf
Swing Tempo RatioIntermediateSwing tempo ratio is the proportion of time spent in the backswing versus the downswing, commonly cited near 3:1 for tour-level swings. It is one of the simplest, most widely coached numbers in swing analysis.Golf
Swing ThoughtBeginnerA swing thought is a single, simple cue a golfer holds in mind right before or during a swing, and most coaches agree that one clear thought. This means or none at all over the ball. This means outperforms trying to consciously manage several mechanical details at once.Golf
Swing WeightAdvancedSwing weight is a measurement of how heavy a club feels during the swing based on where its weight is distributed. It is expressed on a letter-number scale (commonly C9 to D5) rather than the club's total weight in grams.Golf
SwingweightProSwingweight measures how heavy a racquet feels when swung, accounting for where its mass is distributed. Higher swingweight gives more plow-through and power but is harder to maneuver.Tennis
Switch in DoublesIntermediateA switch is a doubles maneuver where partners trade sides of the court. This means one crosses to cover a shot the other cannot reach. This means requiring immediate verbal communication to avoid collisions.Pickleball
T-ServeIntermediateA T-serve is aimed at the center service line, using the shortest distance to travel for speed and taking away the returner's easiest angles.Tennis
T20 FormatBeginnerT20 (Twenty20) cricket is the shortest mainstream format of the game. This means each side bats for a maximum of 20 overs. This means producing fast-paced, high-scoring matches typically completed in under three hours.Cricket
Tag PlayBeginnerA tag play requires a fielder to physically touch a runner with the ball (or a glove securely holding the ball). At the same time, the runner is off the base, since no force is in effect. This means common on steals, run-downs, and any runner not forced to advance.Slow-Pitch Softball
Tag UpBeginnerTagging up means a baserunner returns to and touches their current base as a fly ball is caught, then takes off toward the next base. This means the legal method of advancing on a caught fly.Baseball
TakeawayBeginnerThe takeaway is the first movement of the club away from the ball. Where and how the club moves in the first 18–24 inches often determines the rest of the backswing shape.Golf
Tee HeightBeginnerTee height is how high the ball sits on the tee peg. For a driver, half the ball should sit above the top of the club at address to promote a positive attack angle and high launch.Golf
TempoBeginnerTempo is the overall timing and rhythm of your swing — the ratio of how long the backswing takes versus the downswing. A smooth, repeatable tempo is what makes contact consistent.Golf
TempoBeginnerTempo is the timing ratio between the backswing and downswing — the rhythmic pattern that separates efficient, repeatable mechanics from a rushed or overly slow transition.Analysis Concepts
Ten-Finger Grip (Baseball Grip)BeginnerThe ten-finger (baseball) grip places all ten fingers on the handle with no overlap or interlock. This means a common starting point for young children, beginners. Golfers with limited hand or wrist strength.Golf
Test CricketBeginnerTest cricket is the oldest, longest, and most prestigious format of the sport. This means played over up to five days between two national teams, with each side receiving two innings and ten wickets to be dismissed.Cricket
The SlotAdvanced"The slot" is the ideal delivery channel for the club in the downswing. This means an inside, shallowed path between the target line and the shoulder plane that allows an efficient, in-to-out strike.Golf
Thin DivotIntermediateA thin divot is a shallow scuff or bruise in the turf rather than a proper strip of removed grass. This indicates a shallow, sweeping angle of attack that may be appropriate for some clubs but signals an issue for others.Golf
Thin ShotBeginnerA thin shot is when the leading edge of the club catches the ball near its equator rather than below it. This means the opposite of a fat shot. This means producing a low, skimming ball flight.Golf
Third Shot DriveIntermediateA third shot drive is a hard, low-trajectory shot hit from the baseline on the third shot, used instead of a drop to put pressure on the returning team and force a defensive pop-up.Pickleball
Third Shot LobAdvancedA third shot lob is a high, arcing shot used as the serving team's third shot instead of the more common drop or drive, aimed over the returning team. At the same time, they are still at or near the baseline.Pickleball
Third-Shot DropIntermediateThe third-shot drop is a soft, arcing shot hit from the baseline that lands in the opponent's kitchen. This means forcing them to hit upward and giving the serving team time to advance safely to the kitchen line.Pickleball
Three-and-Two Count StrategyIntermediateThree-and-two count strategy is the hitting approach a batter takes on a full count, where the next pitch either ends the at-bat with a walk or a strikeout, demanding a swing decision that protects the plate rather than hunting for a perfect pitch.Slow-Pitch Softball
Three-PuttBeginnerA three-putt means taking three strokes to hole out after reaching the green. It usually starts with poor distance control on the first putt.Golf
Throwing MechanicsBeginnerThrowing mechanics are the sequence of arm and body movements used to deliver the ball accurately and with arm-safe velocity. This means applicable to every position on the field.Baseball
Throwing Mechanics – FieldingIntermediateThrowing mechanics in cricket fielding refers to the technique for generating an accurate, powerful, low-trajectory throw from the outfield or inner ring to the wicket-keeper or bowler's end stumps.Cricket
Tiebreak StrategyAdvancedTiebreak strategy covers the tactical adjustments players make in a tiebreak's compressed, high-pressure points, including serve selection, return aggression, and side-switch pacing.Tennis
Time Limit RuleBeginnerA time limit rule sets a maximum game duration. This means commonly 50 to 70 minutes in recreational slow pitch. This means after which no new inning starts. This keeps league schedules on track across multiple fields and multiple games per night.Slow-Pitch Softball
Time to ContactAdvancedTime to contact is how long, in fractions of a second, it takes a hitter's swing to travel from its trigger to the ball. This means the metric that ultimately determines how late a hitter can afford to start their swing against a given velocity.Baseball
Time ViolationIntermediateA time violation is a code violation issued when a player exceeds the allowed time between points. This typically penalized with a warning and then a fault or point loss for repeat offenses.Tennis
Timing the ArcBeginnerTiming the arc is the skill of tracking a slow-pitch delivery from release through its peak and descent, and starting the swing. As a result, the barrel arrives exactly when the ball reaches the hittable zone.Slow-Pitch Softball
Timing the Pitcher's ReleaseIntermediateTiming the pitcher's release is a hitter's skill of synchronizing swing initiation to the moment the ball leaves the pitcher's hand near the hip, rather than to the arm circle's motion as a whole.Fast-Pitch Softball
Today — LaunchpadBeginnerThe Today launchpad is SwingVantage's daily entry screen that presents three prioritized cards. This means Focus (what to work on), Practice (the drill to do), and Retest (how to confirm improvement). This means. As a result, every session starts with a clear direction.Analysis Concepts
Toe StrikeIntermediateA toe strike is contact made closer to the outer edge of the clubface than the center. This produces horizontal gear effect that curves the ball left and by a lot reduces ball speed.Golf
Toe Tap Timing TriggerBeginnerA toe tap is a small, quiet lift and set of the front foot used as a timing trigger instead of a full stride. This means it gives the hitter a repeatable rhythm cue with a smaller moving part to keep on time.Baseball
Toe-Down ImpactAdvancedToe-down impact is the natural drooping of the clubhead's toe due to shaft dynamics and gravity during the downswing. This shifts the effective strike location toward the toe if not accounted for at setup.Golf
Toe-Hang PutterIntermediateA toe-hang putter has its head weighted. As a result, the toe droops noticeably when the shaft is balanced on a finger. This means a design that naturally works with a stroke that has an arcing, opening-and-closing rotation.Golf
Tools Grade Scale (20-80)AdvancedThe 20-80 scale is the standard scouting numbering system used to grade each of a player's tools, where 50 represents a Major League average, 80 is elite, and 20 is well below usable at the highest level.Baseball
Top HandIntermediateIn cricket batting, the top hand is the upper hand on the bat handle (for a right-hander, the left hand) and controls straight-bat strokes. This means a strong top hand keeps the bat face straight through the hitting zone.Cricket
Topped BallBeginnerA topped ball is contact made on the upper half of the ball rather than at or near its center. This sends it sharply downward into the ground regardless of how hard the swing was.Slow-Pitch Softball
Topped ShotBeginnerA topped shot is when the club makes contact above the ball's equator. This means hitting the top half. This means. As a result, the ball dribbles forward along the ground with very little height or distance.Golf
TopspinBeginnerTopspin is forward spin imparted by brushing up the back of the ball. It makes the ball dip down into the court and kick up high after the bounce.Tennis
Topspin Contact (Batting)IntermediateTopspin contact happens when the barrel meets the ball above its center, imparting forward rotation that drives it down into the ground quickly. This means the spin signature behind most weak, rollover ground balls.Baseball
Topspin Contact (Slow-Pitch)IntermediateTopspin contact results from hitting the upper half of the ball or rolling the wrists over early. This produces rotation that makes the ball dive downward quickly and shortens its distance.Slow-Pitch Softball
Topspin DinkAdvancedA topspin dink adds forward spin to a kitchen-line dink. As a result, it dips quickly after crossing the net and kicks up on the bounce. This makes it harder to reset cleanly.Pickleball
Topspin LobAdvancedA Topspin Lob is a lob struck with forward topspin. As a result, after clearing the net players, it dips quickly and then accelerates and kicks off the turf and back glass. This makes it much harder to smash than a flat defensive lob.Padel
Total DistanceBeginnerTotal distance is how far the ball travels from the moment it is struck until it stops. This means carry distance through the air plus roll after landing.Golf
Tournament Bracket FormatIntermediatePickleball tournaments typically use one of a few bracket formats. This means round robin pool play, single elimination, or double elimination. This means seeded by skill rating within an age and division group.Pickleball
Trail Elbow CollapseAdvancedTrail elbow collapse is the trail elbow over-folding and losing structure in the downswing. This causes the club to lose width and speed and often forcing a compensating early release or chicken wing.Golf
Trained Eye AssessmentIntermediateA trained eye assessment is an experienced coach's visual read of a swing, drawing on pattern recognition built from watching thousands of swings. This means a genuinely different and complementary skill to numeric or video-based analysis.Golf
TransitionAdvancedThe transition is the moment the swing changes direction from backswing to downswing. How the body initiates this moment determines sequencing, lag, and the resulting club path.Golf
Transition from Baseline to NetIntermediateTransition from Baseline to Net is the process of moving a pair from a defensive back-court position up to net control during a rally, done gradually behind a shot that buys time rather than in one committed rush.Padel
Transition ZoneIntermediateThe transition zone is the mid-court area between the kitchen line and the baseline where players are most vulnerable. This means too close to drive and too far to dink effectively.Pickleball
Transition Zone FootworkIntermediateTransition zone footwork is the controlled, low-to-the-ground movement used to advance from the baseline to the kitchen line without stopping in the vulnerable mid-court area. At the same time, a ball is live.Pickleball
Travel BallBeginnerTravel ball is competitive youth baseball played for a club team outside the local recreational or school league, typically involving tournaments in multiple cities and a higher, more selective level of competition.Baseball
Travel Ball ExposureIntermediateTravel ball exposure is the recruiting value a player gains from playing on a competitive travel team at tournaments and events where college coaches are known to attend and evaluate talent.Fast-Pitch Softball
Trophy PositionIntermediateThe trophy position is the checkpoint at the peak of the service toss. This means hitting arm up, body arched, tossing arm extended. This means where the kinetic chain is fully loaded and ready to fire upward.Tennis
Tunnel PointAdvancedThe tunnel point is the point in a pitch's flight. This means roughly where the batter must decide to swing. This means where two different pitch types are still on nearly identical trajectories before diverging.Baseball
Turn TwoBeginner"Turn two" is baseball slang for successfully executing a double play. This means recording two outs on a single batted ball, most commonly a ground ball fed to a middle infielder who pivots and relays to first base.Baseball
Two-Bounce RuleBeginnerThe two-bounce rule requires the ball to bounce once on each side before either team may volley. This means the serve must bounce on the return side, the return must bounce on the serving side, and only after those two bounces may either team hit a ball before it bounces.Pickleball
Two-Hand FinishBeginnerA two-hand finish keeps both hands on the bat through and beyond contact rather than releasing the top hand. It is favored by hitters and coaches who want maximum control and consistent barrel direction through extension.Slow-Pitch Softball
Two-Handed BackhandBeginnerA two-handed backhand places both hands on the grip, with the non-dominant hand providing additional stability, power, and disguise through contact.Tennis
Two-Handed Backhand (Pickleball)IntermediateA two-handed backhand is a backhand dink or volley hit with both hands on the paddle, trading some reach for extra stability and paddle-face control.Pickleball
Two-Plane SwingIntermediateA two-plane swing lifts the arms onto a steeper, more upright plane than the shoulders establish at address. This produces a taller-looking backswing with more separation between arm swing and body rotation.Golf
Two-Seam Fastball / SinkerIntermediateThe two-seam fastball is gripped along two seams and typically moves arm-side and downward, inducing ground balls rather than strikeouts.Baseball
Two-Strike ApproachIntermediateA two-strike approach is the contact-first adjustment a hitter makes with two strikes. This means shortening the swing, expanding strike-zone coverage, and prioritizing putting the ball in play over power.Baseball
Two-Strike ApproachIntermediateA two-strike approach is the adjustment fast-pitch hitters make when they have two strikes. This means typically shortening the swing, protecting the zone more broadly, and prioritizing contact over power.Fast-Pitch Softball
Two-Strike Choke UpBeginnerChoking up with two strikes means moving the hands up the handle away from the knob, shortening the bat's effective length to gain quicker, more controllable swings at the cost of some raw power.Baseball
Two-Wall Combination (Side + Back)AdvancedA two-wall combination is a ball that rebounds off both the side glass and the back glass in the same sequence. This means typically. This is because it was directed into the corner where the two panels meet. This means creating a compounded, harder-to-read trajectory that attacking players use deliberately and defenders must let fully develop before playing.Padel
Two-Way MissAdvancedA two-way miss is when a player misses both left and right — sometimes hooking, sometimes pushing — because face and path are compensating each other inconsistently.Golf
Two-Way PlayerBeginnerA two-way player is someone who both pitches and plays a position (or hits regularly) at a competitive level, rather than specializing in one role.Baseball
Unattackable BallIntermediateAn unattackable ball is a shot that clears the net and lands low in the opponent's kitchen. This means typically below net height by the time the opponent can contact it. This means. As a result, they must hit upward and cannot drive it aggressively.Pickleball
Under-the-Ball ContactBeginnerUnder-the-ball contact is the opposite of topping the ball. This means the bat meets the lower half of the ball, launching it steeply upward into a pop-up or weak fly ball instead of a line drive.Slow-Pitch Softball
Underhand Serve RuleBeginnerEvery pickleball serve must be struck with an underhand, upward-swinging motion — overhand or sidearm tennis-style serves are not allowed.Pickleball
Understanding ParBeginnerPar is the number of strokes an accomplished golfer is expected to need to complete a hole, including two putts. This means most holes are par 3, 4, or 5, based primarily on the hole's length.Golf
Unforced ErrorBeginnerAn unforced error is a point lost by a player's own mistake on a shot they had reasonable time and court position to execute, without significant pressure from the opponent's previous shot.Tennis
Unit TurnIntermediateA unit turn is rotating the hips and shoulders together as one unit when preparing for a groundstroke, instead of just taking the racquet back with the arm.Tennis
Unplayable LieBeginnerA golfer can declare their own ball unplayable anywhere on the course except a penalty area, then choose from several relief options for one penalty stroke. This means the golfer, not the rules, gets to decide whether a lie is unplayable.Golf
Up-and-Back FormationIntermediateUp-and-back formation is a doubles alignment where one partner is at the kitchen line and the other is at or near the baseline. This means typically occurring during the transition phase of a rally.Pickleball
Up-and-DownIntermediateAn up-and-down is getting the ball into the hole in two strokes from just off the green. This means one chip or pitch (the "up") followed by one putt (the "down"). This means a key measure of short-game efficiency.Golf
Upper CutAdvancedThe upper cut is an attacking stroke played to a short, wide, high ball outside off stump, hitting it over the slips or gully area for four or six.Cricket
Uppercut OvercorrectionAdvancedUppercut overcorrection is when a hitter, trying to add loft or correct a history of topped balls, swings with a bat path noticeably steeper than the pitch's own descent angle, trading ground balls for pop-ups.Slow-Pitch Softball
Uppercut SwingIntermediateAn uppercut swing is a bat path that rises too steeply through the hitting zone. This means beyond the pitch's downward plane. This means producing pop-ups, high infield flies. A short contact window instead of hard line drives.Baseball
Uppercut vs Level SwingIntermediateAn uppercut is an extreme upward bat path; a level swing travels horizontally. In slow pitch, neither extreme is optimal — a slight 5–15 degree upswing matches the ball's descent and produces the most solid contact.Slow-Pitch Softball
USA Softball (ASA) League FormatBeginnerUSA Softball, formerly the Amateur Softball Association (ASA), publishes a softball rule book and approved-bat list. Leagues may adopt its rules for local and championship play.Slow-Pitch Softball
USSSA League FormatBeginnerThe United States Specialty Sports Association (USSSA) runs slow-pitch leagues and tournaments. It uses its own bat rules, team levels, and tournament format.Slow-Pitch Softball
USSSA vs ASA RatingIntermediateUSSSA and ASA (now USA Softball) are the two major bat-certification standards in softball. USSSA allows a higher BPF (up to 1.21) than ASA/USA Softball (1.20). As a result, the same bat may be legal in one but not the other.Slow-Pitch Softball
Vertical Gear EffectAdvancedVertical gear effect is the change in spin rate and launch angle caused by contact above or below the clubface's center of gravity. This means high strikes add backspin and launch, low strikes reduce spin and can flatten trajectory.Golf
Vertical Ground ForceProVertical ground force is the downward-then-upward push a golfer generates against the ground during the downswing, measured on force plates as a multiple of body weight. It is one of the clearest physical contributors to clubhead speed.Golf
VíboraAdvancedA víbora is an attacking sliced overhead. This means Spanish for "viper". This means that combines sidespin with a snapping wrist motion to produce a fast, low ball that skids off the side glass at a difficult angle, applying more pressure than a bandeja. At the same time, preserving net position.Padel
Víbora GripAdvancedThe víbora grip is the slightly adjusted hand position. This means the top knuckle of the index finger rotated marginally further under the handle than a neutral continental hold. This means that frees the wrist to snap laterally at contact, the specific hand mechanic behind the víbora's sidespin rather than the shot's swing path or target.Padel
Vibration DampenerBeginnerA vibration dampener is a small rubber or silicone device inserted at the bottom of the string bed to reduce the high-pitched "ping" vibration and change the sound of the racquet at contact.Tennis
Video Breakdown SessionIntermediateA video breakdown session is a focused review of recorded swing, pitching, or fielding video with a coach or player. It is used to identify specific mechanical patterns and turn them into concrete practice priorities.Baseball
Video LengthBeginnerVideo length is how many seconds of footage you submit. This means long enough to include the full swing motion but short enough not to slow down analysis or introduce irrelevant frames.Analysis Concepts
Video Quality GateBeginnerThe Video Quality Gate is the automatic pre-analysis check that evaluates a submitted clip's usability and blocks or warns before processing video that is too low-quality to produce reliable analysis.Analysis Concepts
Video Quality ScoreBeginnerA Video Quality Score is a pre-analysis rating (0–100) that tells you how usable a submitted clip is before pose estimation begins. This means catching bad angles, motion blur, or poor lighting early.Analysis Concepts
VolleyBeginnerA volley is any shot hit out of the air before the ball bounces. In pickleball it must be struck while standing outside the kitchen — the non-volley zone — making footwork and position as important as stroke mechanics.Pickleball
VolleyBeginnerA Volley in padel is a shot struck before the ball bounces, typically from the net zone, used to maintain pressure, cut off angles, and finish points with authority.Padel
Volley Battle at the KitchenIntermediateA volley battle at the kitchen is a rapid, close-range exchange of firm volleys between two players at the non-volley zone line. This requires quick reflexes rather than a full backswing.Pickleball
Volley TechniqueIntermediateVolley technique refers to the mechanics of striking the ball before it bounces, using a short, firm punch action rather than a full groundstroke swing.Tennis
WaggleBeginnerA waggle is a small, rhythmic movement of the club head before the swing — back and through the hitting area a few times. It relieves tension, previews the takeaway, and sets the swing in motion.Golf
Walk RateIntermediateWalk rate (BB%) is the percentage of a hitter's plate appearances that end in a walk. This means an indicator of plate discipline, pitch recognition. The ability to take advantage of a pitcher's wildness.Baseball
Wall PlayBeginnerWall play is using the glass walls that enclose a padel court. This means letting balls rebound off the back or side glass and playing them after the bounce. This means which keeps rallies alive far longer than in tennis and makes positioning more important than power.Padel
Wall Rebound TimingIntermediateWall rebound timing is the general coaching cue for the shared rhythm underneath every wall shot in padel. This means watch the ball leave the opponent's racquet, track it to the wall, then let it travel its full rebound before committing to a swing. This means the one habit underlying back-glass returns, bajadas, and contraparedes alike.Padel
Warm-Up ProtocolBeginnerA warm-up protocol is a structured pre-session routine designed to prepare the body for skilled movement. This means raising tissue temperature, activating relevant muscle groups, and syncing the nervous system before full-effort swings.Analysis Concepts
Weak GripBeginnerA weak grip rotates both hands toward the target side of neutral. This means fewer than 2 knuckles of the lead hand visible at address. This means which leaves the face open longer and is a common hidden cause of a slice.Golf
Weak GrounderBeginnerA weak grounder is a slowly hit ground ball with little exit speed, typically the result of off-center contact, an unbalanced swing, or contact made too far out front or too deep in the zone.Slow-Pitch Softball
Wearable Sensor (Golf)IntermediateA wearable sensor is a small device clipped to a glove, grip, or belt that measures swing data. This means like tempo, plane, and swing speed. This means directly from its own motion, as an alternative to camera-based video analysis.Golf
Wedge GrindAdvancedWedge grind refers to how the sole of a wedge is shaped and relieved beyond its basic loft and bounce number. This fine-tunes how the club interacts with the turf for specific playing conditions and shot styles.Golf
Weight ShiftIntermediateWeight shift is the deliberate transfer of body weight from the back foot during the load to the front foot during the swing, generating forward momentum that adds power at contact.Slow-Pitch Softball
Weight TransferBeginnerWeight transfer is the movement of the body's center of pressure from the trail side (backswing) to the lead side (downswing). A complete transfer through impact is a fundamental source of power and consistency.Golf
Weight TransferBeginnerWeight transfer in batting is the movement of the batter's bodyweight from back foot to front foot (or vice versa) as the stroke is executed, generating power and setting up correct balance through impact.Cricket
Weighted On-Base Average (wOBA)AdvancedWeighted On-Base Average (wOBA) gives each hitting outcome a run value. It combines walks and hits into one rate that is scaled like on-base percentage.Baseball
Western Forehand Grip TimingAdvancedWestern forehand grip timing refers to the narrower contact-height window a western grip demands. This means meeting the ball too low or too high with this grip produces a much larger error than with a more neutral grip.Tennis
Western GripAdvancedThe western grip rotates the hand fully under the handle (base knuckle on bevel 4–5). This enables extreme topspin on high balls. At the same time, making low-ball and flat shots very difficult.Tennis
What Is a Good Score for BeginnersBeginnerFor most new golfers, shooting somewhere in the 100–120 range on a full 18-hole course is a completely normal and respectable early score. This means breaking 100 typically takes months to a couple of years of regular play, not a single season.Golf
WhiffBeginnerA whiff is a complete miss of the ball during an attempted swing. This is most common among beginners and typically caused by lifting the head or upper body. Other causes include tension, or misjudging the ball's position relative to the swing arc.Golf
Whiff (Air Shot)BeginnerA whiff, or air shot, is a full swing that completely misses the ball. This means it counts as a stroke under the rules. It is a normal, common experience for beginners rather than a sign of a serious problem.Golf
Whiff on Spin vs VelocityProWhiff on spin vs velocity splits a hitter's swing-and-miss rate by pitch category. This means breaking and off-speed pitches versus hard, straight velocity. This means to reveal which specific pitch quality is causing misses rather than treating all whiffs as one problem.Baseball
Whiff RateIntermediateWhiff rate is the percentage of swings that result in no contact at all. This means distinct from chase rate. This measures the decision to swing, whiff rate measures what happens once the swing is already committed.Baseball
WicketBeginnerIn cricket, a wicket refers both to the set of three stumps and two bails at each end of the pitch, and to the act of dismissing a batter. This means "taking a wicket" means getting a batter out.Cricket
WideBeginnerA wide is a delivery that passes outside the marked wide lines on the pitch. This means too far from the batter to be played normally. This means penalising the fielding team with one extra run and requiring the delivery to be re-bowled.Cricket
Wide Serve (Deuce/Ad Court)IntermediateA wide serve is placed near the sideline of the service box, pulling the returner off the court and opening the opposite side for the next shot.Tennis
Wide StanceBeginnerA wide stance places the feet noticeably beyond shoulder width. This adds stability for maximum-effort swings like the driver but reducing the hip rotation available compared to a narrower stance.Golf
WindmillBeginnerThe windmill is the underhand fast-pitch delivery in which the arm makes a full 360° circle before release, generating the velocity and movement-pitch deception that define the game.Fast-Pitch Softball
Windshield Wiper ForehandAdvancedThe windshield wiper forehand finish sweeps the racquet head across the body in an arc resembling a car windshield wiper, generating heavy topspin through extra racquet-face rotation around the ball.Tennis
Windup vs. StretchBeginnerThe windup and the stretch are the two legal pitching positions. This means the full windup, used mainly with the bases empty for maximum power. The stretch, a shorter, quicker delivery used with runners on to control the running game.Baseball
Winner (Shot Outcome)BeginnerA winner is a shot that ends the point outright without the opponent making contact, or with only an unsuccessful attempt at contact.Tennis
Working Ahead in the CountIntermediateWorking ahead in the count means a pitcher reliably gets to counts favoring the defense. This means 0-1, 0-2, 1-2. This means which lets her expand the strike zone and use her best put-away pitch with far less risk.Fast-Pitch Softball
Worm BurnerBeginnerA worm burner is a shot struck with. As a result, little loft delivered to the ball that it skims along the ground for most or all of its distance instead of getting airborne.Golf
Wrapping the BatIntermediateWrapping the bat is a load fault where the barrel rotates too far behind the hitter's head or back. This adds distance and time the barrel must travel to reach the launch position before the swing can even begin.Baseball
Wrist FirmnessIntermediateWrist firmness is the degree to which the wrist is held stable. This means neither locked rigid nor loose and flipping. This means through contact, controlling the paddle face during fast exchanges.Pickleball
Wrist HingeIntermediateWrist hinge is the upward cocking of the wrists during the backswing that creates the angle between the lead arm and shaft. This means storing energy to be released at impact.Golf
Wrist Lay-BackAdvancedWrist lay-back is the extended, cocked-back wrist position that develops naturally late in the forward swing as the racquet head lags behind the hand, storing energy that releases explosively into contact.Tennis
Wrist SnapAdvancedWrist Snap in padel is the rapid rotation of the forearm and wrist through impact used primarily in the vibora, bandeja, and aggressive topspin drives to generate additional pace and spin beyond what arm acceleration alone provides.Padel
Wrist Snap – PitchingIntermediateThe wrist snap is the final acceleration of the wrist and fingers at the moment of release in the windmill delivery. This means the primary source of both pitch velocity and spin.Fast-Pitch Softball
Wrist Snap on ServeIntermediateWrist snap (pronation) on the serve is the forearm-rotation motion through contact that accelerates the racquet head and directs spin, the final link in the serving kinetic chain.Tennis
X-FactorProThe X-factor is the measured angle between the shoulder and hip turn at the top of the backswing. A large X-factor — typically 40–55° — correlates with higher club speed among tour pro players.Golf
Yardage GapsIntermediateYardage gaps are the distance differences between consecutive clubs in your bag. Even, consistent gaps (typically 10–15 yards per club) minimize the situations where no club covers a specific distance.Golf
YipsIntermediateThe yips are involuntary twitches or spasms — most often in putting or chipping — that disrupt the stroke. They are part neurological, part anxiety-driven, and affect golfers at every level.Golf
YorkerIntermediateA yorker is a delivery bowled to pitch right at the batter's feet. This means under the swinging bat. This means one of the hardest balls to score off and a key death-overs weapon.Cricket
Zone Contact RateAdvancedZone contact rate is the percentage of swings at pitches inside the strike zone that result in contact. This means a core measure of basic bat-to-ball ability on pitches a hitter should be equipped to handle.Baseball
Zone DisciplineIntermediateZone discipline is the hitter's ability to reliably swing at pitches in the strike zone and lay off pitches outside of it, even under the pressure of a fast release and movement pitches.Fast-Pitch Softball
Zone HittingIntermediateZone hitting is the approach of only swinging at pitches in the specific area of the strike zone where the hitter is most dangerous. This means avoiding the edges where their swing produces weak contact.Baseball
