Database rebuild in progress; summary data is incomplete. This should only take a few minutes.

- Adjusted ERA (ERA+)
- Earned run average normalized such that the league average pitcher has an ERA+ of 100. The formula is 100×(lgERA/ERA), where lgERA is the league average for the season.
- Adjusted OPS (OPS+)
- On-base plus slugging normalized such that the league average batter has an OPS+ of 100. The formula is 100×[(OBP/lgOBP)+(SLG/lgSLG)-1], where lgOBP and lgSLG are league averages for the season. Because the formula uses the league average on-base percentage and slugging percentage, rather than the league average on-base plus slugging, players can have significantly different on-base plus slugging but a similar adjusted OPS.
- At Bats (AB)
- A player’s total hits and outs. This statistic does not include walks or sacrifices. See also batting average and slugging percentage.
- Batters Faced (BF)
- Number of plate appearances completed while the player was the pitcher.
- Batting Average
- Hits divided by at bats. A measure of how often a batter reaches base due to their influence, as this statistic does not include walks or sacrifice plays (however, the nature of a batter having “influence” on the immaterial plane is a subject for debate).
- Batting Average on Balls In Play (BABIP)
- A measure of how often a batter reaches base only on plays where the defense is involved. Home runs and strikeouts are removed from the standard batting average calculation.
- Caught Stealing (CS)
- A runner put out by the defense while attempting to advance to the next base without the ball being hit into play. See also stolen bases.
- Cold Runners in Scoring Position (CRiSP)
- A runner who is Frozen due to Snow weather while in (or later ending up in) scoring position on second or third base. Frozen players cannot bat for the remainder of the game, so this implies the player was Frozen while on base. This statistic is a contrived backronym in reference to the Columbia River Salmon Passage (CRiSP) Harvest Model, heavily researched by SIBR between the Discipline and Expansion Eras, and later referenced in Blaseball itself during the Expansion Era.
- Complete Game (CG)
- Earned by a pitcher if they are the only pitcher for their team for a full game, including extra innings if played. A pitcher must pitch a complete game to be awarded a shutout, no-hitter, or perfect game.
- Double Plays Grounded Into (GIDP)
- Number of plate appearances that end in the batter and another runner being put out in the same play.
- Earned Run Average (ERA)
- The average number of runs given up by a pitcher in a game. The forumla is 9×R/IP. Commonly used to measure the success of a pitcher. The name “earned run” is a holdover from baseball, where pitchers can be charged with an unearned run due to a fielding error; in Blaseball, players do not err, despite fans’ feelings on the matter. See also adjusted ERA.
- Fielder’s Choice (FC)
- A play where the defense chooses to put a runner out at a further base rather than at first base. Because runners that reach first on fielder’s choice are not improving the game situation for the offense, they are not awarded with a hit.
- Fielding Independent Pitching (FIP)
- A pitching statistic that is similar to earned run average, but only considers home runs, walks, and strikeouts. The formula is (13×HR + 3×BB − 2×SO) / IP + C, where C is the constant that makes the league average FIP equal to the league average ERA. The idea is that the Three True Outcomes this statistic uses are the only outcomes a pitcher has control over; any other outcome is the result of a ball put into play, which is potentially less useful for measuring a pitcher’s overall skill. The usefulness of this statistic for measuring Blaseball pitchers is disputed.
- Games Played (G)
- Number of games this player appeared in playing this position. A batter is credited with having played a game if they have at least one plate appearance. A pitcher is credited with having played a game if they pitched at least once. (Arguably, this definition is too narrow: for example, if a fielder is Shelled before their first plate appearance, it doesn’t count as a game played. Additionally, this currently double-counts players that played for both teams in the same game due to Feedback.)
- Hit (H)
- A single (1B), double (2B), triple (3B), or home run (HR). Runners reaching base on fielder’s choice are not credited with a hit, as they merely replaced a runner put out on a further base.
- Innings Pitched (IP)
- Outs recorded while pitching in a game divided by 3. Used in pitching averages such as earned run average. The divisor is always 3 regardless of the number of outs required to end an inning. The displayed form is fractional, not decimal; 7.2 innings pitched is equivalent to 7 ⅔ innings pitched, or 23 outs recorded. The source of this typographical convention is unclear, but one source indicates including the denominator would make the value more difficult to read in smaller text, and would certainly be redundant if the denominator is always 3.
- Left on Base (LOB)
- For a player, number of runners who were on base when a batter was put out; for a team, number of runners who were on base when the inning ended (alternately, “stranded”). The objective of a batter is to get runners on base to score; batters with a high LOB regularly fail this objective.
- No-hitter
- A complete game pitched with no hits allowed. Separated from a perfect game only by walking a batter.
- On-base Percentage (OBP)
- Roughly, times on base divided by plate appearances. The formula is (H+BB)/(AB+BB+SAC). A measure of how often a batter reaches base. Players that are walked much more often will have a significantly higher on-base percentage than batting average.
- On-base Plus Slugging (OPS)
- On-base percentage plus slugging percentage. Commonly used to measure the overall offensive performance of a player. See also adjusted OPS.
- Perfect Game
- A complete game pitched with every batter faced being put out before reaching base; or, no hits allowed or batters walked. Necessarily, also a no-hitter, but because Blaseball is Blaseball, sometimes not a shutout or even a win.
- Plate Appearance (PA)
- A completed turn batting. Batters complete a turn when they are put out or become a runner. If a runner is caught stealing and ends the inning, the batter is not credited with a plate appearance.
- Runners in Scoring Position (RISP)
- Refers to a runner on second or third base (in usual four-base gameplay). “Team RISP” is a team’s measure of hits per at bat while a runner is on second or third.
- Run Batted In (RBI)
- Credited to a batter for a run scored due to the batter’s time at the plate (except for double plays).
- Run Scored or Allowed (R)
- A runner who crosses home plate is credited with a run. The pitcher that allowed this runner to reach base is charged with a run allowed. A team wins by scoring more runs than the opposing team. See also earned run average.
- Sacrifice (SAC)
- A play that results in the batter being put out at first in order to allow another runner to score.
- Save (SV)
- Awarded to the finishing pitcher of the winning team who did not earn the win, pitched at least one-third inning, and satisfies one of the following conditions:
- Entered the game when the lead is less than three runs, and pitched at least one inning.
- Entered the game with the potential tying run either already on base, or one of the next two batters.
- Pitched for at least three innings.

- Shutout (SHO)
- A complete game pitched with no runs allowed.
- Slugging Percentage (SLG)
- Total bases divided by at bats. A measure of how often a batter hits extra-base hits (doubles, triples, and home runs).
- Stolen Base (SB)
- A runner safely advancing to the next base without the ball being hit into play. See also caught stealing.
- Strikeout (SO)
- A plate appearance that ends due to the pitcher pitching (usually) three strikes and putting the batter out.
- Total Bases (TB)
- The number of bases a player reaches on hits. Singles are 1 base, doubles are 2 bases, triples are 3 bases, and home runs are (usually) 4 bases. See also slugging percentage.
- Walk / Base on Balls (BB)
- A plate appearance that ends due to the pitcher pitching (usually) four balls and the batter advancing to first base. “Base on balls” is the formal term for the rule in baseball, but “walk” is preferred in Blaseball.
- Walks and Hits Per Inning Pitched (WHIP)
- The name of the statistic explains the statistic. The formula is (BB+H)/IP. While earned run average measures a pitcher’s ability to prevent runs, WHIP measures a pitcher’s ability to prevent baserunners.
- Win (W) / Loss (L)
- Earned by a pitcher if they are the most recent pitcher for their team when their team takes or loses the lead for good. A starting pitcher must pitch at least 5 innings to earn the win; if they don’t, the win is awarded to the relief pitcher who pitched the most innings. See also save.
