Data points represent all* MLB pitcher seasons 2002-2009 with 60+IP.
* Actually I excluded a few cases as a result of pulling this data from the dataset of my projection system. So I'm missing all 2009 rookie seasons (except Rick Porcello, who I inserted manually). Also I'm missing 2002-2004 data for all pitchers who were not active during 2005-2009. I should have the full data at some point, but I don't think these omissions matter much, anyway.
