Almost four months after the World Series, Zimmerman was traded on January 30, 1962 to the Minnesota Twins for Dan Dobbek. He played for the Twins for seven seasons, serving mostly as a backup for Earl Battey. When the Twins won the 1965 American League pennant, Zimmerman was one of the few players on the team with previous postseason experience. He appeared in two games for Minnesota in the 1965 World Series and, in his only Fall Classic at bat, ended Game 3 by bouncing into a double play against Claude Osteen. The Twins lost to the Los Angeles Dodgers in seven games.
