One of the most imposing sluggers of his era, Mayberry personified power in Kansas City. He took center stage his first season in Kansas City winning 1972 Royals Player of the Year honors. Through his six seasons with the Royals, Mayberry averaged more than 24 home runs and 94 RBI, and would be named to two All-Star teams. In 1975, he became the first Royals player to post a 30-plus home run season (34), and twice he led the league in walks. He posted the Royals first three 100-plus RBI seasons, and ranks among the Royals all-time leaders in home runs (143) and RBI (552).
