Kalish could need surgery on shoulder

Ryan Kalish, who injured his left shoulder diving for a ball on Thursday while playing for Triple A Pawtucket, has a partially torn labrum that could require season-ending surgery according to a source close to the outfielder.

Kalish, who is a left-handed thrower, has started in a rehabilitation program and will be evaluated in 2-3 weeks. If the tear in his shoulder does not respond to treatment, surgery would be the next step.

The Red Sox described the injury as a “significant sprain” after Kalish was examined in Boston on Friday.

Kalish, 23, hit .252 with four homers and 24 RBIs in 53 games for the Sox last season. He is considered the team’s top outfield prospect. With right fielder J.D. Drew in the final year of his contract, Kalish is considered a strong candidate for the 2012 lineup.
