Carl Yastrzemski, the last batter to win the Triple Crown
The Triple Crown is pretty easy to understand: if one single batter leads his league in homeruns, runs batted in (RBI), and batting average, he wins the Triple Crown. No one has earned the honour since 1967, when Boston's Carl Yastrzemski achieved the feat.
