Los Angeles Angels outfielder Josh Hamilton will be out six to eight weeks due to a tear to his ulnar collateral ligament, which will require surgery, according to Mike DiGiovanna and Bill Shaikin of the Los Angeles Times.
Hamilton, 32, tore the ligament -- located in his left thumb -- when he slid headfirst into first base in a Tuesday contest against the Mariners.
So far this season, Hamilton is hitting .444 with two home runs and six RBIs. The Angels currently sit at 3-5.
Last season, which was his first with the Angels, Hamilton hit .250 with 21 home runs and 79 RBIs, his worst hitting season since 2009. In December 2012, Hamilton signed a five-year, $125 million contract with Los Angeles.
