San Francisco Giants infielder Casey Schmitt underwent surgery on his left wrist on Tuesday and will be sidelined 8 to 10 weeks.

Schmitt had the carpal boss removed during the procedure that was performed in Los Angeles.

Schmitt injured the wrist when he was hit by a pitch from Calvin Faucher of the Miami Marlins on June 25. Once he returned from the injured list on July 7, Schmitt had trouble swinging the bat without pain.

Schmitt, 26, is considered the frontrunner to be the Giants' starting second baseman this season.

He batted .237 with 12 homers and 40 RBIs in 95 games last season. In three seasons with San Francisco, Schmitt is batting .228 with 23 homers and 86 RBIs in 225 games.
