According to the Doctors they haven't even slowed down growing and the growth plates are still "wide open". Their path in baseball has been interesting. They played little league through their 12 year old year, never having a pitching coach, or really being pushed. It was only when they decided to take on travel ball that they made the real decision to push themselves. I've always said that as soon as they aren't having fun anymore, we are done playing. And I mean that. They are getting stronger every day and the doctors project them to be about 6'8" for whatever that is worth.
