Red Sox Place Mayer on Injured List with Sprain

Boston Red Sox rookie infielder Marcelo Mayer has been placed on the 10-day injured list with a right wrist sprain, retroactive to Thursday, after leaving Wednesday's win over the Phillies. Mayer, who has a history of wrist problems, experienced a 'tight grab' during a swing and will undergo further evaluation, with surgery not ruled out and a second opinion to be sought. The Red Sox recalled infielder David Hamilton from Triple-A Worcester to fill Mayer's roster spot. Mayer will miss at least the weekend series against the Los Angeles Dodgers, and the severity of the injury remains uncertain. Mayer had been hitting .228 with four home runs and was a key contributor during Boston's AL Wild Card chase. His absence leaves the Red Sox infield thin as they continue their playoff pursuit.
