Blalock headed to DL with tear in left hamstring

Texas Rangers third baseman Hank Blalock has a small tear in his left hamstring and will be out at least three weeks. Blalock hurt himself running out a double Friday night. Last season, Blalock was limited to 58 games after having surgery in May to remove a rib that affected nerves in his throwing shoulder.Blalock returned to the lineup in September, but only as a designated hitter for the rest of the season. That's the only other time in his seven major league seasons he has been on the DL.
