In 1991, Morris signed a one-year contract with his hometown Minnesota Twins. He enjoyed another great season, posting 18 wins with a 3.43 ERA, and an even better postseason after Minnesota won the AL West. Morris won both of his starts over the Toronto Blue Jays in the ALCS, and his team went on to face the Atlanta Braves in the World Series. Morris started for the Twins three times in the series, going 2–0 with a 1.17 ERA, making his final outing in the deciding Game 7. In a postseason performance for the ages, the 36-year-old hurler threw 10 innings of shutout baseball against the Braves, as the Twins won the game 1–0 on a 10th-inning single by Gene Larkin that scored Dan Gladden. Morris was named the World Series MVP for his performance, and joined fellow pitcher Sandy Koufax as the only players to win the Babe Ruth Award twice. He holds the record for most wins by a Twin in a single postseason, with four in 1991.
