Play Index Glossary

Positions - Using the numerical position names (1 = Pitcher, 2 = Catcher, ..., D = Designated Hitter), this shows the positions played by the player in descending order of games played. An '*' indicates they played half or more of their games at that position, and a / denotes the break between more than and less than ten games for single seasons and more than or less than 100 games for more than a single season.

GmSc - Game Score - This is a value created by Bill James that evaluates how good a pitcher's start was.


Batting Game Score - This is a value also created by Bill James, but not nearly as widely known. I've modified it. My goal is to identify the heroes and anti-heroes from each day and highlight them, so feel free to quibble with the weighting.

Start with 0 points. Add 40 points for a cycle, 30 for a 3-HR game and 10 for a 2-HR game. Add 1 point for each run, RBI, 2B, SB, BB, and HBP recorded. Add 2.5 for each hit, 3 for each 3B and 4 for each HR. Subtract 1 for each CS and GIDP, subtract 2 for each error, 0.2 for each SO and 0.5 for each AB. I should have LOB's in here somewhere, but I don't track that in my player gamelogs since no one can agree on a definition.

tOPS+ - OPS+ of this split relative to the player or team's overall OPS: 100*((split OBP/total OBP) + (split SLG/total SLG) - 1)

sOPS+ - OPS+ of this split relative to the major league OPS for this split: 100*((split OBP/ML avg. OBP of split) + (split SLG/ML avg. SLG of split) - 1)

BAbip - Batting Average on balls in play: measures what happens when the player puts the ball in play on the field. This is typically consistent for pitchers, but will vary wildly between batters.: (H-HR)/ (AB - SO - HR + SF)

DR - Day's Rest

Situat. In/Out Inn Rnr O Scr

These entries give the situation (Inning, Runners, Outs, Relative Score) when the pitcher entered the game and then again when they left.

Inning is a number and t or b for top or bottom.

Rnr lists the runners on base, for example --- means no baserunners and 1-3 would mean runners on the corner.

O is the number of outs, if it was the end of the game, no baserunners were listed and it instead says "end". If they just completed the inning it says, 3 out. "start" means they started the game.

Scr stands for the score and has tie for a tie game or a for ahead by some number of runs or d for down by some number of runs.

For example, 1b start tie 7b --3 2 d 1 would mean they entered with the game tied in the bottom of the first and left in the bottom of the seventh, down 1 with two outs and a runner on third.

If the text is red, you can click it to get the context of the game, the fielders in the field and the names of the runners on base along with the batter up.

App,Dec - Lists the starting and ending innings for the player.

  • GS-10: Started game and left in the 10th inning.
  • CG 9: Played the entirety of a nine-inning game.

  • 3-9f: Entered in third inning and played until the end of the game in the ninth inning.
  • 4-5: Played the fourth and fifth innings.
  • W, L, S: earned a win, loss, or save respectively.
  • eoI - This is the batting team's relative score at the end of the inning.

    soP - This is the batting team's relative score at the start of the play.
