Leonard was a true workhorse, as durable and dependable as any pitcher in the game. He was named Royals Pitcher of the Year three times and posted seasons with 20 or more wins on three occasions. Leonard finished his career leading the Royals all-time list in complete games (103) and shutouts (23) and he was second in wins (144). He also held the club's single-season bests in starts (40), complete games (21), and innings pitched (294.2) and strikeouts (244). From 1975 to 1981, Leonard collected 130 wins -- the most by any right-handed pitcher in Major League Baseball.
