Keith Foulke, RP
Foulke made 29 inconsistent appearances for the Red Sox this season before winding up on the DL with right elbow tendinitis. After surrendering his closer's role to Jonathan Papelbon at the beginning of the season, Foulke appeared to settle into his new setup role. Unfortunately it was not to be, as the month of May saw Foulke's ERA rise by almost 2 runs over the previous month.
