The Twins contended for the 1992 American League Western Division title for much of the season but finished six games behind the Oakland Athletics, who won the division for the fourth time in five seasons. The Twins' 90–72 record was their last winning campaign until 2001, Kelly's last season as manager. Over the next several seasons, the players that made up the core of the 1987 and 1991 Twins slowly began to leave. Gladden, the left fielder, departed in the offseason for Detroit. Morris, the pitching hero of the series, signed with Toronto and returned to the World Series the next year. Gagne and Davis departed after the 1992 season and Harper at the end of the 1993 season. Hrbek's production began falling due to injuries that kept him off the field for much of the next two seasons, and he retired in 1994. The Twins traded away both Erickson and Tapani (neither ever regained his 1991 form) in 1995, and Puckett retired due to a loss of vision in his right eye caused by glaucoma. Knoblauch was the last hitter of the 1991 team to remain in Minnesota, eventually forcing a trade after the 1997 season to the Yankees, with whom he won three additional World Series titles. After being traded to the playoff-bound Red Sox in 1995, Aguilera returned to the Twins in 1996, used by Kelly as a starter. Aguilera returned to the pen in 1997, and stayed until midway through the 1999 season, the last remaining player from the 1991 team. Traded to the Cubs, he finished his career with Chicago that season.
