Baseball's "Iron Horse," Lou Gehrig teamed with Babe Ruth to form the sport's most devastating tandem.

His .361 batting average in seven World Series led the New York Yankees to six titles.

Despite a series of devastating injuries, Mantle accumulated a long list of impressive accomplishments, finishing his 18-year career with 536 home runs and a .298 batting average. When healthy, Mantle was an excellent defensive outfielder - lightning fast, with a strong and accurate arm. The switch-hitter won three MVP Awards and a Triple Crown, contributing to 12 pennants and seven World Series titles for the New York Yankees, all while establishing numerous Fall Classic records. Elected 1974.

In 1997, Robinson was honored posthumously when Major League Baseball universally retired his uniform number 42. Elected 1962.

Still an American icon decades after his death, George Herman "Babe" Ruth emerged from humble beginnings to become the game's greatest slugger and gate attraction. Ruth hit home runs at a prodigious rate - his single season output often exceeded those of entire major league teams. He retired with 714 career home runs, at a time when only tow other players had reached 300. He also posted a record of 94-46 in 163 games as a pitcher, most coming before he became a regular in the outfield. Reggie Jackson once deflected a comparison to "The Sultan of Swat," saying, "There will never be another Babe Ruth. He was the greatest home run hitter who ever lived." Elected 1936.
