After two seasons in the minor leagues, he made his major league debut late in the 1969 season for the pennant-winning Twins managed by Billy Martin, however he didn't qualify for the post-season roster. Dempsey spent a few more seasons shuttling between the Twins and their minor league teams, before being traded to the New York Yankees in October 1972. During his tenure with the Yankees, he served as a reserve catcher to Thurman Munson, and received tutoring from Yankees coach and former catching standout, Jim Hegan.
