They must have won the lottery, I don't know any minor leaguers who went on to own a major league team.
I always kick myself when Bull Durham is brought up as a subject, I had the chance to be an extra in the movie. My friends and I were playing in the South Square mall arcade, and some lady asked if we'd like to show up to the DAP as extras. All we would have had to do was cheer and "act warm". (It wasn't warm when they filmed it). I had to go to work instead, and since I had already called in sick too much, it was either go flip burgers or get fired. Grrrrrrrrrr.
