No one could have known in 1966 and 1967, when Frank Robinson and Carl Yastrzemski won back-to-back Triple Crowns, that the feat wouldn't be matched again for 45 years. Miguel Cabrera ended that drought Wednesday night. But Cabrera wasn't the only player to make history in 2012, as three pitchers threw perfect games -- the most in a single season. Both achievements are rare; just 23 pitchers have tossed perfect games, and only 10 hitters have led in batting average, runs batted in and home runs since 1920. And keep this in mind: Of those 10 Triple Crown hitters, the previous nine are in the Hall of Fame.
