Former MLB umpire Steve Palermo died at 67 Sunday following a battle with cancer, and he unquestionably left his mark on the league. Palermo was a prominent official who made the majors in 1976 and appeared headed for the Hall of Fame, but had his umpiring career cut tragically short when he was shot and initially paralyzed from the waist down trying to stop a mugger at a Dallas restaurant in July 1991.
