Bill James<\/a>, measures a starting pitcher’s effectiveness in a single game. It uses a system of pluses and minuses to create a score. That score can easily be compared to standard benchmarks to determine how well the pitcher performed.<\/p>\n\n\n\nHow is Game Score used?<\/h2>\n\n\n\n
Game score is analyzed on a fairly intuitive scale. A score of 50 reflects an average outing. Conversely, scores of 0 or below (very bad) or 100 or greater (very good) rarely happen. <\/p>\n\n\n\n
The average score for a starting pitcher at home is slightly higher than for the road starter, reflecting baseball’s home field advantage. In practice, the difference comes from a better strikeout rate for home starters. Some believe that unconscious bias by home plate umpires causes that difference, giving a few extra strikes per games to the home side.<\/p>\n\n\n\n
Game score often correlates closely with pitching wins. However, this correlation breaks down at the very top end of the scale (scores of 90 or more). Many of these very high scores happen in games that go to extra innings, making it much harder for the starting pitcher to pick up the win.<\/p>\n\n\n\n
