Quiet and unassuming, Gehrig struggled to make friends with many of his colorful and spotlight-hungry Yankee teammates, especially Ruth. But his hardworking nature and ability to play through incredible pain certainly earned their respect, and earned him the nickname "The Iron Horse." Yankee fans, meanwhile, were thankful just to have him in the lineup. His Hall of Fame career saw him score 100 runs and knock in at least that many in 13 consecutive seasons. In 1931, he set an American League record by clubbing 184 RBIs, and in 1932, he became the third player to hit four home runs in a single game (it's only been done 16 times ever). Two years later, he took home baseball's coveted Triple Crown by leading the league in home runs (49), average (.363) and RBIs (165).
