We begin with a recent history of Orioles starting rotations.
2008: Jeremy Guthrie is the only pitcher to start double-digit games and post an ERA under 5.00. The Orioles churn through 13 different starting pitchers. Matt Albers and Steve Trachsel throw 11 starts combined. Total fWAR: 3.4; MLB rank: 30th
2009: Guthrie continues to eat innings. Future closer Koji Uehara throws 12 inspiring starts. Future nominal ace Chris Tillman throws 12 extremely uninspiring starts. Rich Hill and Adam Eaton (pitcher version) combine for 21 starts and post ERAs of 7.
