Re: How many players can each minor league team have?
I remember when we visited the Baseball Hall of Fame a number of years ago, we asked to see the contract card for a friend of ours who played in the minors for the Reds during the 50's. He started with the Class B Sudbury (PA) Redlegs (I'm not certain of the class though) and then had a stint in the Army in Germany and then returned and played with Albuquerqe, but I can't remember which level they were then. He hurt his arm pitching in the cold German weather, so he washed out shortly after returning.
That said, when he looked at the card and saw all the teams his contract had been assigned to, he said "I never played for that club" or some other one. I've been looking at the scrapbook his mother kept then and there are even copies of all of his contracts, etc. Very interesting and I may write an entry sometime about it, but I want to get his okay first.
He was Sandy Koufax's roommate at UC during their southern tour his senior year (Koufax's freshman, and only, year at UC). Koufax mentions him in his biography about the longest home run he ever gave up in a game against XU.
