TORONTO — Red Sox pitcher John Lackey walked off the mound in the fifth inning on Saturday clutching his right arm with what appeared to be a significant injury.
Based on television replays, he appeared to feel something in his arm on the fifth pitch he threw to Toronto’s Jose Reyes, a curveball.
The next pitch was well inside and nearly hit Reyes. Lackey immediately grabbed his arm above the elbow and walked off the mound in the direction of second baseman Dustin Pedroia.
Manager John Farrell and head athletic trainer Rick Jameyson rushed out to the field and escorted Lackey back to the dugout.
Lackey had struck out Emilio Bonafacio for his eighth strikeout and was pitching very well with no signs of problems. He had allowed a two-run homer to J.P. Arencibia in the fourth inning.
Lackey was making is first start since Sept. 25, 2011. He missed all of last season recovering from Tommy John elbow surgery.
Lackey was replaced by Alfredo Aceves. We’ll have more news as it becomes available.
