On May 10, 2005, Rolen injured his shoulder in a collision with Dodgers first baseman Hee-Seop Choi and was placed on the disabled list two days later. He was expected to be out four to six weeks. On May 13, he underwent shoulder surgery; an additional MRI revealed a tear in the labrum. He eventually opted to have surgery on his shoulder, rather than attempt to let it heal on its own and return for the playoffs. He finally returned to full-time duties in 2006, a year in which Rolen was one of six nominees for the National League Comeback Player of the Year award. He finished 2006 hitting .292, hitting 22 home runs and 95 RBI. Rolen and the Cardinals won the 2006 World Series over the Detroit Tigers. On September 15, 2006, Rolen set a personal record for RBIs in a game with 7 in a 14–4 win against the San Francisco Giants, hitting 2 home runs.
