Boston Red Sox closer Joel Hanrahan left Monday's outing against the Minnesota Twins with right forearm tightness.
Hanrahan left the game one pitch after giving up a game-tying, ninth-inning home run to Twins second baseman Brian Dozier. After Hanrahan's first pitch to the next batter, first baseman Justin Morneau, Red Sox manager John Farrell came out to the mound with the training staff and took Hanrahan out of the game.
The Red Sox said later that Hanrahan has right forearm tightness and would be re-evaluated on Tuesday.
Hanrahan's injury came just hours after the Red Sox placed reliever Andrew Bailey on the disabled list with biceps soreness. Bailey had been the team's closer in Hanrahan's absence.
The 31-year-old Hanrahan was recently activated off the DL. Hanrahan, who was acquired from the Pittsburgh Pirates last offseason, has struggled immensely in 7 1/3 innings pitched this season. He has a 9.82 ERA, 2.18 WHIP and just five strikeouts to six walks.
