Musial was named a vice president of the St. Louis Cardinals in September 1963, and he remained in that position until after the 1966 season. From February 1964 to January 1967, he also served as President Lyndon B. Johnson's physical fitness adviser, a part-time position created to promote better fitness among American citizens. Before the 1967 season began, the Cardinals named Musial the team's general manager, and he oversaw the club's World Series championship that year. He won the allegiance of Cardinals players by making fair offers from the outset of player-contract negotiations and creating an in-stadium babysitting service so players' wives could attend games.
