In a relatively brief 10-year career, which was shortened by a back ailment, Ralph Kiner hit 369 home runs, winning or sharing the National League home run title in each of his first seven seasons in Pittsburgh. He topped 50 twice, with 51 in 1947 and 54 in '49. His ratio of 7.1 home runs per 100 at-bats trails only Babe Ruth and Mark McGwire among retired players. Kiner averaged better than 100 RBI a season as he led the National League in slugging percentage three times.
