Run support

Run support is a baseball statistic used to assess a starting pitcher's support by the team's offense in actual runs scored. It measures how many runs were scored by his team on average when he starts. It is considered a somewhat important statistic because a team (and its pitcher) earn wins by holding its opponents to fewer runs than it scores. Since a pitcher's skill is a large factor in how many runs the opponent scores and a non-factor in how many runs his team scores, this is a measure of whether the pitcher happened to pitch on days when his team scored a lot. There are two different measures of run support. These statistics may be adjusted for park and league factors.^[1]

1. The number of runs scored per nine innings of opponent batting during the pitchers starts.^[2]
2. The number of runs per start.^[1]
