Had to look him up. Nuxhall pitched 2/3 of an inning in 1944 at age 15. Then retired. Pitched again in MLB, for the Reds, beginning in 1952. Finally retired in 1966. He was a broadcaster for the Reds from when he retired until he died in 2007, although he was a part-time broadcaster the last three or four years. Probably not a pitching coach.
