Game Score is a pitcher stat that measures a starting pitcher’s performance in a specific game.
After searching for a box score of a game, many times you can find how many pitches a hurler tossed in the game and then you will find the Game Score. This measures the effectiveness of the pitcher.
Game Score Calculation
Start with 50 points-Add 1 point for each out recorded (or 3 points per inning)- Add 2 points for each inning completed after the fourth- Add 1 additional point for every strikeout
Remove 2 points for each hit allowed- Remove 4 points for each earned run allowed
Remove 2 points for each unearned run allowed- Remove 1 point for each walk allowed
(This formula was created by Bill James). there is a slightly different formula created by Tom Tango.
To get a perfect game score, a pitcher would get 114 points and that is a perfect game with all out as strikeouts.
To date, there have been four 20 strikeout games and here are the Game Score(s) for each one:
- Kerry Wood Game Score was 105 on May 8, 1998
- Roger Clemens Game Score of 97 on Sept. 18, 1996
- Roger Clemens 97 April 29, 1986
- Max Scherzer 87 on May 11, 2016
Not all games are created equal. Wood threw a one-hitter but a shutout and the others gave up runs in their game.
