Ted “Double Duty” Radcliffe played in the Negro Leagues for many years. He got his nickname because he would sometimes catch one game of a doubleheader and pitch the other. He played professionally until 1954, when he retired at age 52. He is the oldest player to ever appear in a professional baseball game, throwing one pitch for the Schaumberg Flyers of the Northern League in 1999 when he was 96.
John Gordon, of course, has been a radio broadcaster for the Twins since 1987.
Tommy Moore was drafted by Minnesota in the twenty-eighth round in 1966, but did not sign.
