Musial won his second World Series championship in 1944, then missed the entire 1945 season while serving in the Navy. After completing his military service during the war, Musial returned to baseball in 1946 and resumed his consistent hitting. That year he earned his second MVP award and third World Series title. His third MVP award came in 1948, when he finished one home run short of winning baseball's Triple Crown. After struggling offensively in 1959, Musial used a personal trainer to help maintain his productivity until he decided to retire in 1963. At the time of his retirement, he held or shared 17 major league records, 29 National League records, and nine All-Star Game records.
