Tudor's pitching propelled the Cardinals into the playoffs. He lost Game 1 of the National League Championship Series against the Los Angeles Dodgers but won Game 4 to even the series and St. Louis won 4 games to 2. Tudor was masterful in Game 1 of the 1985 World Series against the long-shot Kansas City Royals, and even better with a shutout in Game 4. However, he completely fell apart in Game 7, allowing five runs and four walks before being pulled in the third inning. The Royals rolled to an 11-0 victory for their first World Championship, and Tudor was saddled with the loss. Tudor was so upset by his performance in Game 7 that in a post-game tantrum he cut his pitching hand after punching an electrical fan.
