Upon joining the Cardinals, Smith helped the team win the 1982 World Series. Three years later, his game-winning home run during Game 5 of the 1985 National League Championship Series prompted broadcaster Jack Buck's "Go crazy, folks!" play-by-play call. Despite a rotator cuff injury during the 1985 season, Smith posted career highs in multiple offensive categories in 1987. Smith continued to earn Gold Gloves and All-Star appearances on an annual basis until 1993. During the 1995 season, Smith had shoulder surgery and was out nearly three months. After tension with his new manager Tony La Russa developed in 1996, Smith retired at season's end, and his uniform number (No. 1) was subsequently retired by the Cardinals. Smith served as host of the television show "This Week in Baseball" from 1997 to 1998.
