Red Sox manager John Farrell said Hanrahan is dealing with right hamstring soreness, according to NESN’s Ricky Doyle. Farrell said that Andrew Bailey will close in the mean time. There has been no decision made whether Hanrahan will have to spend any time on the disabled list.
Hanrahan has an 11.57 ERA through six appearances so far in 2013. He has allowed six hits and walked five through 4 2/3 innings.
On Saturday Hanrahan entered a 1-1 ballgame and was lifted after walking Evan Longoria and Ben Zobrist. The closer did not record an out in the appearance.
