Synonymous with the New York Yankees for nearly two decades, switch-hitter Mickey Mantle (1931-1995) hit 536 homers, including a record 18 home runs in World Series play. A three-time American League MVP, he won the Triple Crown in 1956.
Nicknamed "Campy," Roy Campanella (1921-1993) hit 242 home runs during his ten-year career with the Brooklyn Dodgers, the famous "Boys of Summer." A three-time National League MVP, he was also the first black catcher in the history of Major League Baseball.
Hank Greenberg (1911-1986) is remembered as one of the all-time greatest right-handed batters. During his time with the Detroit Tigers, "Hammerin' Hank" led the American League in home runs and in RBIs four times each, and he was twice named Most Valuable Player.
Known for his unusual but powerful high-leg-kick batting stance, Mel Ott (1909-1958) distinguished himself with the New York Giants for 22 seasons. Ott was the first National League player to hit 500 home runs, and he led the league in homers six times.
