Walters would help lead the Reds of and to back-to-back National League championships. The 1939 Reds, behind Walters' 27 victories and MVP-Award-winning season, captured the NL pennant by 4½ games, but they were swept by the New York Yankees in the World Series. Unfazed, the 1940 Reds won 100 games, with Walters accounting for 22 victories and leading the circuit in earned run average for a second straight season. They repeated as league champions by a 12-length margin, then, behind Walters' two complete game victories, they defeated the Detroit Tigers in a seven-game World Series for the second world title in modern club history.
