Who was the first player to have his birth date written on his uniform - month and year ?

Question

I also believe he's the only one to ever do it. First correct answer wins, tell me the player's name, the number he wore and for what team.

Sorry folks - my bad - month and date, not year.

Answer 1

It was Carlos May of the White Sox. He was born on May 17th, and his number was 17, so his uniform would read "May 17".

That's a good question.
