“Game Score” is a Bill James invention that assigns a formula-based number to every start by a starting pitcher, based on his innings pitched, runs and hits and walks allowed, and strikeouts racked up, during that particular game. For more detail on the Game Score formula you can check here: Game Score – Wikipedia .

The idea behind Game Score is to have a single number that summarizes the level of “dominance” a starter achieved during his appearance. A Game Score of 100 might be achieved with, say, a complete-game one-hitter with two walks and 17 Ks. In contrast, a zero Game Score might be a one-inning start giving up nine runs on seven hits and three walks with no Ks.
