Armed with a fastball, a slider, and a forkball,[1][2] Morris was a five-time All-Star (1981, 1984, 1985, 1987, and 1991), and played on three World Series Championship teams (1984 Tigers, 1991 Minnesota Twins, and 1992 Toronto Blue Jays).

[4] He is one of ten players in MLB history to have won back-to back World Series championships on different teams, with the other nine being Allie Clark, Clem Labine, Bill Skowron, Don Gullett, Ryan Theriot, Jake Peavy, Ben Zobrist, Joc Pederson, and Will Smith.

Morris broke into the Tigers' starting rotation in 1979, posting a 17–7 record and a 3.29 ERA and establishing himself as the ace of the Detroit staff.

Morris, along with catcher Lance Parrish, shortstop Alan Trammell, second baseman Lou Whitaker, outfielder Kirk Gibson, and manager Sparky Anderson, played a notable role in turning the Tigers into a contending team for most of the 1980s.

Despite playing for the notorious "Captain Hook" (Anderson),[10] nicknamed because of his tendency to pull his starters at the first sign of weakness, Morris was known for finishing games.

[11] On April 7, 1984 (on NBC's nationally televised Game of the Week), Morris no-hit the Chicago White Sox at Comiskey Park,[12] beginning what would be an excellent season for both him and the Tigers.

While teammate Alan Trammell was named World Series MVP, Morris was given the Babe Ruth Award for most outstanding performance in the 1984 postseason.

Despite a sub-par season in 1989 when he made only 24 starts and won just 6 games, he finished the 1980s with 162 wins, the most by a major league pitcher during the decade.

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.

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 won a fourth ring in 1993, as the Blue Jays repeated as World Champions with a victory over the Philadelphia Phillies in six games.

However, Morris was not a factor in the Blue Jays World Series repeat: he pitched poorly for the team in the regular season, finishing 7–12 with a 6.19 ERA, and was not used at all in the postseason due to a season-ending injury.

In 1996, he made a brief return to professional baseball, this time playing with his hometown St. Paul Saints of the independent Northern League.

[32] After falling off the regular ballot, Morris was elected to the Hall by the Modern Era portion of the Veterans Committee in December 2017.

On April 30, 1987, Morris pitched a complete game victory over the California Angels; in the eighth, DH Mike Heath moved to first base, thus eliminating the designated hitter for the rest of the contest.

Morris came up with two out in the ninth, hitting a foul fly to right; it was his first time in the batter's box since playing for the minor-league Evansville Triplets in 1977.
