Red Sox infielder Lowrie reportedly played with wrist injury

Boston Red Sox rookie shortstop Jed Lowrie slumped down the stretch and in the playoffs this season, and an injury might have been partly to blame.

In an e-mail to the Boston Globe on Wednesday, Red Sox general manager Theo Epstein revealed that the infielder played since May with a sprain and a small non-displaced fracture in his left wrist. He originally suffered the injuries while playing for Triple-A Pawtucket.

Lowrie underwent an MRI exam on Tuesday, and the injury, which worsened as the season continued, has already begun to heal itself. According to Epstein, three weeks of rest will heal the wrist.

According to the Boston Globe report, the injury caused Lowrie, a switch hitter, occasional pain and affected the strength of his grip, especially when he batted lefthanded (.222, .334 slugging percentage). Batting righthanded, he hit .338 with a .525 slugging percentage.

Lowrie, called up in July when Julio Lugo was injured, played in 52 of 53 games for the Red Sox in August and September, and committed only one error in the regular season, none as a shortstop.

Lowrie finished the season in an 8-for-51 slump and batted only .207 in the playoffs. He completed his rookie season with a .258 average with two homers and 46 RBIs in 81 games.
