Who was the Last Triple Crown Winner?

No horse has won the Triple Crown since the 1970s, when Secretariat (1973), Seattle Slew (1977) and Affirmed (1978) all won the honor within five years. But that’s nothing compared to baseball; the last hitter to win the Triple Crown (leading the league in batting average, home runs, and RBIs) was the great Mickey Mantle in 1956.
