For example, which reliever had a better game?
Code:
IP H R ER BB SO 1.1 1 1 1 0 1 1.1 1 1 1 2 0
One way to correct that is by using inherited runners scored. But that's not really exact, since it's hard to blame pitchers for coming into a bad situation. One I like to use that measures a similar skill is Win Probability Added over Leverage Index. It takes into account both runners inherited as well as new runners put on by the reliever himself.
I'm running out of time, so that's all for now.
