Run Support Per Nine Innings measures the average number of runs a team scores when the starting pitcher is in the game on a per nine inning basis. This is calculated as:
RS/9 = (Run Support/Innings Pitched) * 9
More about Run Support Per Nine Innings Leaders
Pitchers leading the league in run support per nine innings have the most runs scored by their offense while they are still in the game on a nine inning basis. A pitcher must play for a good offensive team in order to be among the league leaders as this statistic is entirely team dependent. Leaders in run support per nine innings are more likely to lead their league in wins than the average pitcher, as wins are also a team dependent statistic. While pitching for a team with an above average offense is needed to be among the leaders, year after year there is relatively little consistently in who shows up among league leaders, as it is something of a “fluky” statistic.
