Angels Uniform #50
1972 - 94: Angel coach Jimmie Reese
This is a strange case. Longtime Angels coach Jimmie Reese had his jersey number posthumously retired by the Angels. Prior to his hiring, no Angel player or Manager had ever worn #50.
TRIVIA TIME: Jimmie Reese is not the only person in baseball history with a retired jersey # that no player ever wore in their club's history. Name the other four (the answer is in the comments section).
