BOSTON -- Red Sox left-hander Rich Hill, who had pitched well out of the bullpen since his call up from Pawtucket on May 5, left Wednesday's game with what the team called an injury to his left forearm.
Hill clutched his elbow in apparent agony after throwing ball four to Adam Dunn, the only batter he faced in the seventh inning of Boston's game against the White Sox. After just a brief consultation with manager Terry Francona and assistant trainer Greg Barajas, Hill left the game.
"He said he felt something pop in there and just like a burning,'' catcher Jarrod Saltalamacchia said. "Hopefully, everything turns out OK but it's sort of scary when it's the elbow."
Red Sox manager Terry Francona said Hill had left the ballpark and was undergoing an MRI at Massachusetts General Hospital.
"He felt obvious discomfort in his forearm,'' Francona said. "A cursory examination, he actually looked OK, which was good. But we certainly feel the need to get him checked out thoroughly. Hopefully we'll know a little more tonight.''
Hill had not allowed an earned run in eight previous appearances this season, retiring 24 of the 30 batters he faced. The native of Milton, Mass., had allowed just one hit to left-handed hitters this season (1 for 14) as he refashioned his pitching delivery, dropping down sidearm before adjusting his arm angle slightly upward.
For the moment, Hill is the only left-handed reliever on the Sox roster. They could bring back Hideki Okajima from Pawtucket or Felix Doubront, who just recently returned to the Pawtucket rotation after a stint on the DL with a groin injury.
