211 terms
- 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 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
- 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
- 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
- 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
- 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
- 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
- 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
- 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
- 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
- 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
- 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
- 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
- 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
- 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
- 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 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
- 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
- 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
- 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
- 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-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–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
- 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
- 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
- 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
- In-Between HopAdvancedThe in-between hop is the awkward bounce that reaches a fielder around shin or knee height. This means too high to pick off the dirt, too low to receive comfortably out front. A common source of errors on routine-looking ground balls.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
- 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
- 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
- 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
- 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-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
- 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
- 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
- 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-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
- 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
- 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
- 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
- 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
- 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
- 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
- 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
- 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
- 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
