Hoping for a comeback season, Red Sox outfielder Ryan Kalish suffered a setback and will undergo surgery on his right shoulder next week, a baseball source told MLB.com on Friday night. Sox third baseman Will Middlebrooks talked to Kalish Saturday morning. Kalish, who turns 25 shortly before Opening Day, underwent shoulder and neck surgeries in 2011 that impacted him last season. After an arduous rehabilitation, Kalish hit .378 with four home runs in nine games with Pawtucket and was recalled by the major-league Red Sox last June coincidentally, when Sweeney went on the disabled list with a toe injury. But Kalish subsequently struggled while Sweeney was out, posting a .217/.238/.250/.488 batting line, and was optioned back to Triple-A on July 7, when Sweeney was reactivated. The Red Sox quickly moved to add to their outfield depth, signing Ryan Sweeney, who was nontendered by the club after last season, to a minor league deal. The Sox moved quickly to shore up their outfield by re-signing free agent Ryan Sweeney to a Minor League deal.
