The Cardinals swept the Atlanta Braves in the 1982 National League Championship Series, with Andújar starting and winning Game 3. He started two games in the 1982 World Series against the Milwaukee Brewers, winning both with a 1.35 ERA. He was taken off the field during Game 3 after he was hit in the leg by a line drive. St. Louis manager Whitey Herzog later said that he thought Andújar had been killed by the batted ball, but Andújar recovered in time to start Game 7.
