There's a really interesting study that was just published on FanGraphs about Pitcher DL trips (Part I, Part II). BtB also published a graph to go along with the data. Quick facts: *- There's a 30% chance any given starter sees DL time. *- The probability that at least one of the four Phillies pitchers will end up on the DL is approx. 89%. Oswalt is at 50% to see DL time, Halladay is around 44%, Lee is at 43%, and Hamels is at 31% (Blanton is at 40%).
