wOBA: Weighted On-Base Average. Values each batting outcome by its contribution to scoring, using the matching season's run weights. Intentional walks are excluded. Formula: Weighted sum of unintentional BB, HBP, 1B, 2B, 3B and HR ÷ (AB + BB − IBB + SF + HBP).
wRAA: Weighted Runs Above Average. Batting runs above or below league average at the same number of plate appearances. Negative values are below average. This measure is not adjusted for ballpark. Formula: (wOBA − league wOBA) ÷ wOBA scale × PA.
wRC: Weighted Runs Created. Estimated batting runs created from wOBA and plate appearances, using the matching season's league scoring environment. This is not park-adjusted wRC+. Formula: [(wOBA − league wOBA) ÷ wOBA scale + league runs per PA] × PA.

Batted-ball data

Recorded measurements and MLBDB estimates from the pitches seen and the balls put in play as a hitter. Each table's note says which.

MLBDB calculates these numbers from recorded game measurements. EV balls and LA balls show the sample sizes. EV+LA balls have both measurements and are used for barrel percentage. Seasons without these measurements show N/A.

BBE: Batted Balls. Completed turns to bat that ended with a batted ball, including home runs. Some balls have no speed or angle measurement.
EV+LA balls: Balls with Recorded Speed and Angle. Balls that have both a usable speed and angle measurement. These are the balls used to calculate barrel percentage.
MLBDB barrels: MLBDB Barrels. Balls hit very hard at an angle suited to deep hits. MLBDB checks the recorded speed and angle against its documented barrel zone. Balls missing either measurement are left out. Rounded measurements can affect close calls. This is MLBDB's calculated classification.
MLBDB Barrel%: MLBDB Barrel Percentage. The percentage of balls with both speed and angle recorded that MLBDB counts as barrels. Missing measurements are left out. Formula: 100 × barrels ÷ balls with recorded speed and angle.
EV balls: Balls with Recorded Speed. All batted balls with a usable speed measurement, including bunts. This is the sample used for hard-hit percentage.
Avg EV balls: Average Exit Velocity Sample. Balls with recorded speed, excluding labelled bunts. Used for average and maximum exit velocity.
Avg EV: Average Exit Velocity. Average ball speed just after contact, in miles per hour. Balls with no speed measurement are left out. Balls labelled as bunts are excluded. Unknown bunt labels are retained. Formula: Sum of recorded speeds excluding labelled bunts ÷ Avg EV balls.
Max EV: Maximum Exit Velocity. The fastest recorded batted ball, in miles per hour. Balls labelled as bunts are excluded. Unknown bunt labels are retained.
Hard-hit%: Hard-Hit Percentage. The percentage of speed-measured balls hit at least 95 miles per hour. Formula: 100 × hard-hit balls ÷ balls with recorded speed.
LA balls: Balls with Recorded Angle. All batted balls with a usable angle measurement, including bunts. This is the sample used for sweet-spot percentage.
Avg LA balls: Average Launch Angle Sample. Balls with recorded angle, excluding labelled bunts. Used for average launch angle.
Avg LA: Average Launch Angle. Average angle at which the ball leaves the bat, in degrees. A negative angle points toward the ground. Higher is not always better. Balls labelled as bunts are excluded. Unknown bunt labels are retained. Formula: Sum of recorded angles excluding labelled bunts ÷ Avg LA balls.
Sweet-spot%: Sweet-Spot Percentage. The percentage of angle-measured balls launched from 8 to 32 degrees. Formula: 100 × sweet-spot balls ÷ balls with recorded angle.

Direction is estimated from recorded hit locations and the hand used to bat on each play. Rates divide by Located balls and show N/A below 95% location coverage. Unmapped balls are left out. Higher is not always better.

Located balls: Balls with Usable Hit Locations. Balls whose recorded location and batting hand support an estimate of pull, center or opposite-field direction.
Location coverage: Hit-Location Coverage. The share of all balls that can be mapped. A rounded 95% can be slightly below the cutoff; the cutoff uses the original counts. Formula: 100 × located balls ÷ all batted balls.
Pull%: Estimated Pull Percentage. The share of located balls hit toward the batter's pull side. Uses located balls only. N/A when fewer than 95% of all balls can be mapped. These are chart-based estimates. Formula: 100 × pulled balls ÷ located balls.
Center%: Estimated Center-Field Percentage. The share of located balls estimated toward center field. Uses located balls only. N/A when fewer than 95% of all balls can be mapped. These are chart-based estimates. Formula: 100 × center-field balls ÷ located balls.
Oppo%: Estimated Opposite-Field Percentage. The share of located balls hit toward the side opposite the batter's pull side. Uses located balls only. N/A when fewer than 95% of all balls can be mapped. These are chart-based estimates. Formula: 100 × opposite-field balls ÷ located balls.
Pull balls: Estimated Pulled Balls. Balls estimated toward the pull side: left field for right-handed hitters, or right field for left-handed hitters.
Center balls: Estimated Balls to Center. Balls estimated toward center field, regardless of batting hand.
Oppo balls: Estimated Opposite-Field Balls. Balls estimated toward the opposite side: right field for right-handed hitters, or left field for left-handed hitters.
Unmapped balls: Balls with Unusable Hit Locations. Balls with missing details, unusable coordinates or locations outside the field area used for these estimates. They are excluded from direction percentages.

Pitches counts every pitch actually thrown; automatic balls and strikes are left out. Swings include bunt attempts, and caught foul tips count as whiffs. Whiff% divides misses by swings; SwStr% divides misses by pitches. Zone rates need a recorded location for at least 95% of pitches. Missing results show N/A. For 2018 through 2024, inside or outside the zone is an MLBDB estimate from recorded pitch locations and batter zone heights; from 2025, MLB's recorded zone labels are used.

Zone coverage: Pitch-Location Coverage. The share of delivered pitches with a usable location. Zone rates need at least 95% coverage, checked before rounding.

MLBDB estimates these from recorded ball speed and angle, for seasons from 2018. A season or period shows N/A if any batted ball it needs is missing a measurement or falls outside what the model covers. That is common over a full season, and in 2018 and 2019 no regular player has complete measurements. Differences use actual results from the same completed games. These describe recorded contact, not future performance.

Model balls: Measured Balls Used in Estimates. Eligible batted balls with both speed and angle recorded. Defensive awards that do not count as at-bats are excluded.
Measured%: Expected-Stat Measurement Coverage. The share of eligible batted balls with both speed and angle recorded. Each expected statistic shows N/A if any contact value it needs is missing or outside model support.
MLBDB xBA: MLBDB Expected Batting Average. Estimated hits per at-bat from ball speed, angle and same-season running speed when available. Strikeouts remain at-bats. Each needed contact contribution must be available. Reviewed seasons are 2018 through 2026; the current season is provisional. Formula: Estimated hits in at-bats ÷ at-bats.
AVG − MLBDB xBA: Batting Average Minus Expected. Recorded batting average minus the estimate, using the same completed games. A positive number means the actual result was higher. This does not measure luck alone.
MLBDB xSLG: MLBDB Expected Slugging Percentage. Estimated bases from hits per at-bat. Singles count once, doubles twice, triples three times and home runs four times. Formula: Estimated total bases in at-bats ÷ at-bats.
SLG − MLBDB xSLG: Slugging Minus Expected. Recorded slugging minus the estimate, using the same completed games. A positive number means more bases were recorded than estimated.
MLBDB xwOBA: MLBDB Expected Weighted Batting Average. Combines reconstructed expected contact values with recorded walks and hit-by-pitches. Walks and hit batters use the same season's batting weights. Intentional walks are excluded. Every needed contact value must be available.
wOBA − MLBDB xwOBA: Weighted Average Minus Expected. Recorded weighted batting average minus the estimate, using the same completed games and batting weights.
Missing pairs: Balls with Incomplete Measurements. Eligible balls missing speed, angle or both. These inputs are not filled in. The affected expected statistic is N/A, and the real appearance remains counted.
