Stat guide

Games the player appeared in as a batter or a runner.

Every completed turn at bat, however it ended. A catcher's interference is not one: it counts only in CI.

Plate appearances that count toward the batting average: walks, hit by pitches and sacrifices are left out.

Runs the book credits to the player. A run scored by a temporary runner belongs to the player they ran for.

Runs the player scored themselves. R gives a temporary runner's run to the player they ran for; aR keeps it with the runner. Otherwise the two are the same.

Times the batter reached safely on a batted ball without an error or a fielder's choice.

Hits on which the batter reached second base.

Hits on which the batter reached third base.

Hits on which the batter scored, over the fence or inside the park.

Home runs on a ball that stayed in play.

Hits for more than one base.

Runs that scored because of what the batter did. No RBI on a double play, on an error with two out, or for a run that scored on an error, wild pitch or passed ball.

Four balls, intentional or not.

Walks the defence chose to give.

Times the batter was awarded first base after being hit by a pitch.

Plate appearances that ended on a third strike, swinging or looking.

Bunts that moved a runner up at the cost of the batter. Not an at-bat.

Fly outs on which a runner scored. Not an at-bat.

Times the batter was awarded first base because the catcher interfered with the swing. It is counted here and nowhere else: not a plate appearance, an at-bat, a walk or a time on base.

Times the batter reached base because a fielder made an error. An at-bat without a hit.

Ground balls on which two outs were made.

Balls put in play from a bunt or a slap, whatever came of them.

How often an at-bat ends in a hit.

How often the batter reaches base without making an out. Intentional walks count. A catcher's interference is neither a time on base nor in the denominator.

OBP with the intentional walks left out of both halves.

Total bases an at-bat. A single counts one, a home run four.

Getting on base and hitting for power in one number.

Extra bases an at-bat: slugging with the singles taken out.

How often a ball put in play falls for a hit. Home runs over the fence are out of both halves; one that stayed in the park is a ball in play.

BABIP with every home run left in: all hits over the at-bats that were not strikeouts, plus sacrifice flies.

Share of plate appearances that end in a walk.

Share of plate appearances that end in a strikeout.

Walk rate less strikeout rate, in percentage points.

Bases gained beyond the single: extra bases, walks and steals, an at-bat.

An estimate of the runs a batter's line produced: times on base multiplied by bases advanced, over opportunities.

On-base percentage with each way of reaching base counted for what it is worth in runs. Intentional walks are out of the weights and the denominator. The weights are the competition's own once it has played enough.

Runs the batter added with the bat compared with an average batter in the same number of plate appearances.

Runs the batter created in all, from wOBA.

Runs created a plate appearance against the competition, where 100 is average and 120 is 20% better.

Pitches thrown to the batter.

How long the batter makes a pitcher work.

Share of pitches the batter swung at.

Share of swings that missed.

Share of swings that fouled the ball off.

Share of pitches that were a called strike or a swing and miss.

Share of balls in play hit on the ground.

Share of balls in play the scorer marked as hit hard.

Balls in play hit hard: fly balls, line drives and hard ground balls.

Balls in play hit on a line.

Balls in play hit in the air to the outfield.

Balls in play hit on the ground.

Balls in play hit high and short.

One for every plate appearance that began with the player standing on a base, from any base and whether or not the base ahead was open. Two runners on is two opportunities. An attempt from a situation the plate appearance did not begin in (the runner reached that base during it) adds one, so Att% never passes 100%.

Attempts the book credits to the player.

Steals and times caught stealing, as scored, by the player who ran.

Bases stolen, as the book credits them.

Stolen bases scored for the player who ran. SB gives a temporary runner's steal to the player they ran for.

Times thrown out stealing, as the book credits them.

Times caught stealing scored against the player who ran. CS gives a temporary runner's to the player they ran for.

How often an attempt succeeds.

How often the player's own attempts succeed.

Times the runner was put out by a pickoff throw.

Bases taken while the defence threw somewhere else.

How often the runner goes when they could.

The attempts the tournament would have made with the same opportunities in the same situations. A situation is the base the runner is on, whether the base ahead is taken and how many are out; the tournament rate in it is every runner of that season together, the player included.

How much more often a runner goes than the tournament would in their place. Every steal opportunity is sorted by its situation - which base the runner is on, which bases ahead of them are taken (a runner on third is told apart only by first and third with second empty), how many are out - and the tournament has an attempt rate for each of the 24. Adding those rates up over the runner's own opportunities gives the attempts an average runner would have made (xAtt); AAA is the attempts actually made less that number. +2.0 means two more attempts than average with the same chances, 0 is the tournament average, below zero is a runner who stays put. It measures the decision to go, not whether it worked, and counts whoever ran. A team's or a manager's AAA is its runners' added up.

Attempts as a share of what the tournament would have made, where 100 is the tournament average. Shown from one expected attempt.

How close to the most aggressive runner (or team, on a team's line) in each situation. The highest rate in a situation is the highest among those with at least five opportunities in it, or the player's own if that is higher, so 100% is running as often as whoever runs most and it never passes that.

Five signs of speed, each marked out of ten and averaged: stealing success, how often they go, triples, runs scored once on base, and double plays avoided.

Runs gained or lost by stealing, against an average runner who reached first as often. A row for one situation is measured against the tournament in that situation.

Runs saved by staying out of double plays, against the tournament's rate in the same chances.

Runs gained by taking the extra base on hits, measured in run expectancy against what that hit usually leaves.

Earned runs for every nine innings pitched.

Earned run average over n innings, n being the innings in the season's rules (7 where it does not say). Shown only where n is not 9, since ERA is that.

Baserunners allowed an inning.

An ERA-scale figure from home runs, walks other than intentional ones, hit batters and strikeouts only, weighted 13, 3, 3 and -2. The constant puts it on the competition's ERA scale.

Hits allowed for every nine innings. H/n is the same over a regulation game.

Strikeouts for every nine innings. K/n is the same over a regulation game.

Share of balls in play against the pitcher that were hit hard.

Balls in play hit hard against the pitcher.

One for every runner standing on a base when a plate appearance began with the pitcher on the mound, from any base. An attempt from a situation the plate appearance did not begin in adds one.

Steals and times caught stealing, as scored, with the pitcher on the mound.

How many more runners went on the pitcher than the tournament would have sent in the same situations. Below zero means runners stay put.

Attempts against the pitcher as a share of what the tournament would have made, where 100 is the tournament average. Shown from one expected attempt.

Games the player took a position in.

Innings the player stood in the field.

Share of the player's defensive innings, over every position, spent at the position picked. It appears only when a position (or the outfield) is picked.

Plays the fielder had a hand in.

Outs the fielder completed: a catch, a tag, a force.

Throws or deflections that led to an out made by somebody else.

Runs saved by throwing runners out more often than the tournament does in the same number of attempts. Given once the competition has five games of its own.

Runs saved by not being run on at all: the attempts the tournament would have made against this catcher that nobody dared. A chance is a plate appearance with a runner able to go: the lead runner on first or second with the next base open, or anybody on third. Given once the competition has five games of its own.

What a catcher's arm is worth in all: the runners thrown out and the ones who never went.

Called strikes among the pitches taken with the catcher behind the plate, against what the same pitchers get from other catchers (with or without you): each pitcher's share of taken pitches called strikes over the competition's seasons, less this catcher's that season, times the pitches this catcher took of theirs. It does not allow for the umpire or the pitch location. 100 is average; from 150 taken pitches.

The extra called strikes from framing, in runs. A strike in place of a ball is worth the difference between the two counts it leads to, from how the competition's own plate appearances went through each count.

Called strikes among the catcher's located taken pitches, against how often the competition calls a strike at that distance from the edge of the batter's zone (a curve fitted to its own located calls, with 200 needed). 100 is average; from 150 located taken pitches.

The extra called strikes from framing by location, in runs, at the same run value of a strike as FrRV.

Wild pitches and passed balls the catcher prevented, against what the competition lets by with the same pitches.

WPA from batting and baserunning.

WPA from pitching.

Everything the player added, with the plays that cost left out.

Everything the player cost, with the plays that helped left out.

How much a plate appearance can move the game compared with an ordinary one. 1 is average; a tied ninth with the bases loaded is far above it.

How tense the player's moments were on average.

WPA with the tension taken out, so a hit counts the same whenever it came.

Whether the player did better in tense moments than in ordinary ones. Zero is the same either way.

Runs a position player added over an average one, bat and legs together.

Runs added over a replacement-level player in the same playing time. For a pitcher: wRP - replacement rate x BF. Replacement level is the 20th percentile of the competition.

A position player's runs above average, in wins.

A pitcher's runs prevented above average, in wins.

Wins and losses of the games managed.

Share of games won.

Runs scored less runs allowed.

Wins and losses in games decided by one run.

Plate appearances in which a bunt was shown.

How often the manager bunts.

Runners sent.

Every substitution line the manager's team made in the games they signed the card for, counted one line at a time (a new pitcher who also moves a fielder is two): pitching changes, pinch hitters, pinch runners, temporary runners, defensive changes and re-entries.

Moves for every game the manager signed the card for.

New pitchers brought in.

Batters sent up for somebody else.

Runners sent in for somebody else.

Courtesy runners for the pitcher or catcher.

Substitutions and position changes in the field.

Starters brought back into the game.

Strikes called on pitches the batter did not swing at.

Share of the pitches nobody swung at that were called strikes: called strikes over balls plus called strikes. Hit batters, intentional walks, illegal pitches, no-pitch rows and substitutions are not counted.

On an umpire's or a scorer's calls table: called strikes over the pitches called a ball or a strike, for the calls left after the filters. The zone view gives the same share for each zone.

Strikeouts on a called third strike.

Share of strikeouts that ended on a called strike.

Outs the umpire had a part in calling.

Located called strikes that were in the zone.

Located called strikes that were outside the zone.

Share of located called strikes that were outside.

Located called balls that were in the zone.

Share of located called balls that were in the zone.

Located calls that went against the zone by more than two centimetres: a strike with the middle of the ball outside the zone, or a ball inside it. The zone is as wide as the plate and as tall as the batter's own zone; a ball touching the edge across is a strike, up and down the whole ball must be inside.

Share of located calls that were not potential missed calls: they agreed with the zone or missed it by no more than two centimetres.

For each umpire (or pitcher) the scorer shared games with and who was also in games the scorer did not keep: the scorer's located calls with them times their PMC rate in the other games, added up.

A scorer's missed calls against expectation, counted over the shared calls only. Over 100, their locations disagree with the calls more than other scorers' do. From 150 shared calls.

Games entered from another play-by-play.

Games scored while they were being played.

Scoring at the ground against the same teams away from it. Over 100 favours hitters.

The range the run factor could reasonably lie in with this few runs.

The runs these games would have had at a neutral ground.

The same comparison for each kind of event.

Share of games won, a tie counting half.

How far a team is behind the leader.

Runs scored.

Runs allowed.

The WBSC tiebreaker: runs scored an inning at bat less runs allowed an inning in the field.

The same with earned runs only.
