The Twins lost to the Los Angeles Dodgers in the 1965 World Series. In 1967, Zimmerman played in 104 games as Battey was troubled by health issues. The Twins were in first place with two games left in the season, but lost their final two games to the Boston Red Sox and finished the season in second place. Although he was still an active player, Zimmerman became the Twins' unofficial bullpen coach in 1967, as the Twins only had three coaches during that time. After Battey's release in the off-season, the Twins traded for catcher John Roseboro, and Zimmerman went back to being a reserve player during the 1968 season. He was released by the Twins on March 18, 1969.
