The Detroit Tigers today announced that designated hitter Victor Martinez tore the ACL in his left knee during off-season conditioning last week and likely will miss the 2012 season. Martinez will be re-evaluated by Dr. Richard Stedman next week and surgery to repair the torn ACL in his left knee is anticipated. Martinez hit .330 with 12 home runs and 103 RBIs in 145 games with the Tigers last season. He signed a $50 million, four-year contract before last season.
