thanks, so is there formulas for those, or does a certain site calculate them? I don't use VORP much, but FIP is a great stat: FIP = [13*HR + 3*BB - 2*K] / IP + ~3.2 Not the easiest to calculate, so its much easier to look it up at a place like Fangraphs.com. The 3.2 is a league factor that makes the average FIP equal to the average ERA, so it changes slightly every year. FIP takes out the BABIP and LOB% that can inflate or deflate a pitchers ERA. A pitcher really has not control over those things, therefore he depends on luck. Bush's ERA is 6.13, but his FIP is just 4.17.
