wily mo pena was in the Majors at 19.
just sayin'.
Actually WMP was a September call up and he was 4 months shy of his 21st B-day. Also he wasn't a full time player when he was brought up (which was my original statement regarding 19 year olds in the majors). WMP was an oddity in that he was inexplicably brought up before he was ready. I can't think of another teenager that was brought up to sit on the bench like WMP. I can't explain why they did that with him and I'm certainly not advocating promoting Marrero. I'm just saying that he can't be called a special player.
