- Four-Seam FastballBeginnerThe four-seam fastball is the most common pitch in baseball — gripped across all four seams — and is usually the hardest, straightest pitch a pitcher throws.Baseball
- Four-Seam Grip (Throwing)BeginnerA four-seam grip means holding the ball across four seams before a throw, not however it lies in the glove. It gives a straight, true throw with maximum carry.Baseball
- Framing a PitchAdvancedFraming is how a catcher receives a borderline pitch so it looks like a strike. The catcher uses soft hands and sticks the pitch where it arrives.Baseball
- Front Door Breaking BallAdvancedA front door breaking ball starts at a same-handed batter as if it might hit them. Then it breaks back over the inside corner for a strike.Baseball
- Front Foot LandingBeginnerFront foot landing is when the stride foot plants to anchor hip rotation. Its timing to pitch release is the biggest factor in being on time, late, or rushed.Baseball
- Front Shoulder Flying OpenIntermediateThe front shoulder flies open when it turns toward the pitcher too early. That pulls the eyes and barrel off the ball, causing weak, pulled contact or a miss.Baseball
- 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
- Ground Ball RateIntermediateGround ball rate (GB%) is the percentage of batted balls that are grounders — usually 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 is the overall shape of a hitter's batted balls. It shows whether their attack angle produces grounders, fly balls, or a mix.Baseball
- Hand PathIntermediateHand path is the route the hands travel from launch position to contact. A direct, efficient path keeps the barrel in the zone longer and prevents casting.Baseball
- Hard-Hit RateAdvancedHard-hit rate is the percentage of batted balls struck above a set exit-velocity threshold — usually 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. A moving head makes it harder to track the ball and find the barrel reliably.Baseball
- High-Hands SetupBeginnerHigh hands in the stance or load position means the hands are set above the back shoulder. A launch position that gives the barrel a longer, downward-into-the-zone path to the ball.Baseball
- Hip Rotation (Batting)IntermediateHip rotation is the hips turning hard toward the pitcher to start the swing. It is the engine of rotational power, firing before the hands or barrel move.Baseball
- 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
- Hit-and-RunIntermediateA hit-and-run is a called play where the runner breaks with the pitch and the hitter must swing and make contact. Ideally a ground ball protects the runner.Baseball
- Hitch in the SwingIntermediateA hitch is an extra dip of the hands, down or back, after the load has started forward. It creates a second, unplanned load that costs time against velocity.Baseball
- 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
- In-Between HopAdvancedThe in-between hop is an awkward bounce at shin or knee height. It is too high to pick off the dirt and too low to field out front, a common cause of errors.Baseball
- 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
- Innings Limit (Youth)BeginnerAn innings limit is a cap on the total number of innings a young pitcher is permitted or recommended to throw. The cap covers a season or year. It is intended to manage cumulative throwing workload beyond any single game's pitch count.Baseball
- 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 — the single biggest predictor of stolen base success.Baseball
- Knuckle CurveAdvancedA knuckle curve is a curveball gripped with a bent finger pressed knuckle-first against the ball. It gives a tighter spin axis and a later, sharper break.Baseball
- 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
- Lead Off BaseBeginnerA lead off base is the distance a baserunner takes from the bag before the pitch — maximising lead distance reduces the distance to the next base while managing pickoff risk.Baseball
- Leg KickIntermediateA leg kick lifts the front knee high during the load to build rhythm and stored energy. It is a bigger, riskier trigger than a toe tap or no-stride approach.Baseball
- Line Drive RateIntermediateLine drive rate (LD%) is the share of batted balls that are line drives, usually hard-hit at a 0–25° launch angle. Liners have the highest expected batting average.Baseball
- LoadBeginnerThe load is the small backward gathering of the hands and weight just before the swing starts. It coils the body to store energy that fires into the ball.Baseball
- Long Toss ProgramIntermediateA long toss program is a planned throwing routine for arm strength and conditioning. Players gradually throw well past game distance, then work back down.Baseball
- Lunging (Batting)BeginnerLunging is a timing fault where a hitter commits weight and stride forward too early. It drains rotational power before the swing even begins.Baseball
- No-Stride ApproachIntermediateA no-stride approach keeps the front foot planted, triggering the swing with hands and hips alone. It trades a little rhythm for simpler, more reliable timing.Baseball
- On-Base Plus Slugging (OPS)IntermediateOPS is a hitting stat that adds on-base percentage and slugging percentage. It combines reaching base and hitting for power in one 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
- Opposite Field HittingIntermediateOpposite-field hitting drives the ball away from the hitter's dominant-hand side. It means letting the pitch travel deeper and not rushing the swing to pull it.Baseball
- Pickoff MoveIntermediateA pickoff move is a pitcher's legal throw (or step) toward a base with a runner on. It is aimed at catching that runner off the bag before a pitch is thrown.Baseball
- Pitch Count LimitBeginnerA pitch count limit is a maximum number of pitches a player is allowed to throw in a single game or appearance. It is set by league rules based on age, and usually paired with required rest days before pitching again.Baseball
- Pitch MixIntermediateA pitcher's pitch mix is the combination and proportion of pitch types thrown — for example 55% fastball, 20% slider, 15% changeup, 10% curveball — and how that mix shifts by count and batter.Baseball
- Pitch RecognitionIntermediatePitch recognition is identifying a pitch's type and location early — out of the pitcher's hand and from spin — so the hitter can commit to a swing or take decision before it's too late to act.Baseball
- Pitch SequencingAdvancedPitch sequencing is the art of ordering pitches to exploit a hitter's tendencies and set up future offerings — making each pitch more effective because of what came before.Baseball
- Pitch TunnelingAdvancedPitch tunneling is throwing different pitch types on the same early flight path so they separate late. The hitter can almost never tell them apart in time.Baseball
- Pitch VelocityBeginnerPitch velocity is the speed of the ball at release, measured in miles per hour — the most commonly cited indicator of pitching power and arm strength.Baseball
- Pitching DeceptionAdvancedPitching deception is any part of a pitcher's mechanics, grip, or delivery that delays or confuses the hitter. It disguises pitch type, speed, or location.Baseball
- Plate DisciplineIntermediatePlate discipline is the ability to tell balls from strikes and swing only at pitches a hitter can do damage on. It is the core mental skill of hitting.Baseball
- Player Development PlanIntermediateA player development plan is a written, individual outline of a player's current skill level, priorities, and checkpoints. It replaces a generic practice routine.Baseball
- Pop Time (Catcher)AdvancedPop time is the time from a pitch hitting the catcher's mitt to the throw reaching the glove at second base. It measures a catcher's throw on a steal attempt.Baseball
- Pop-Up (Batting)BeginnerA pop-up is a batted ball with extreme backspin and a very steep launch angle (above 50°). It goes nearly straight up and is almost always caught for an out.Baseball
- Productive OutIntermediateA productive out is an out that still helps the team. It might advance a runner, score a run, or move a runner into scoring position.Baseball
- Projectable FrameIntermediateA projectable frame is a lean, usually tall young body with room to add strength and size. Scouts expect that growth to bring power, velocity, or bat speed.Baseball
- Pull Side HittingIntermediatePull-side hitting drives the ball to the same side of the field as the hitter's dominant hand. It comes from early contact and usually carries the most power.Baseball
- Quality At-BatBeginnerA quality at-bat is judged by process and competitiveness, not just outcome. A long count, a hard-hit ball, a walk, or moving a runner can count without a hit.Baseball
- Quick PitchAdvancedA quick pitch is a pitcher delivering the ball before the batter is set and ready in the box. It is an attempt to catch the hitter off guard that is illegal at most levels of play.Baseball
- Range FactorAdvancedRange factor is a traditional defensive stat: putouts plus assists per game (or per nine innings). It roughly estimates how much ground a fielder covers.Baseball
- RBI OpportunityBeginnerAn RBI (run batted in) opportunity is a plate appearance with a runner in scoring position (second or third base). The hitter has a real chance to drive in a run.Baseball
- Reading a HopIntermediateReading a hop is judging early where a ground ball's bounce will arrive. The fielder can then set footwork and glove angle before the ball gets there, not after.Baseball
- Reading the Ball off the BatAdvancedReading the ball off the bat is judging a batted ball's path, speed, and landing spot just after contact. It uses bat angle and early flight, not the full arc.Baseball
- Relay ThrowIntermediateA relay throw breaks one impossible outfield throw into two makeable ones. An infielder runs out to take the first leg, then turns and throws the second.Baseball
- Release PointIntermediateRelease point is the precise spatial location in front of the body where the pitcher lets go of the ball — consistency here is the foundation of command.Baseball
- Rolling OverIntermediateRolling over is a swing fault where the top hand rotates over the bottom hand too early. It closes the barrel through contact, causing weak pull-side grounders.Baseball
- Rotational HittingIntermediateRotational hitting is a swing model powered mainly by hip and torso rotation, not forward weight shift. It is the dominant power model in modern baseball.Baseball
- Sacrifice BuntBeginnerA sacrifice bunt trades the batter's own out to advance a runner into scoring position. It is a situational strategy, not an attempt to reach base safely.Baseball
