He reached the pinnacle of his managerial career in 1979 as the skipper of the Pirates' 1979 World Series champion team. The team included future Hall of Famers, first baseman Willie Stargell and pitcher Bert Blyleven, along with curmudgeonly stars like third baseman Bill Madlock and outfielder Dave Parker. Tanner guided the team together, and the players selected the Sister Sledge hit "We Are Family" as their theme song. The Pirates were able to win the World Series after falling behind three games to one to the Baltimore Orioles. Hall of Fame manager Sparky Anderson wrote of the Pirates, "They do everything with abandon, because that's the way Chuck Tanner wants it. He's an aggressive manager, a manager who doesn’t go by the book. That's why Pittsburgh is such an exciting team." 1979 would be Tanner's only divisional winner as a manager.
