Can't control your height but you can control your strength. Know a guy who is 5'8" on a good day. Had the second highest single season ncaa D1 BA ever I believe. Played some milb. Strong. Very strong. Coached a kid who was about the same size maybe even shorter. Strong, very strong. Got drafted. Size may stop you as a pitcher at some point but not as a positional player.
height may not stop you but it can be one hell of a hindrance. based on the feedback we have received at least. there have been multiple comments of "I wish he were bigger" "I wish he was taller"
I have no doubt if he were 4 inches taller he would be committed to a D1 right now, as it is he is talking with D2 and some very good D3. The fact that he isn't fast hurts as well but he is strong, stronger and better then several guys in his spot who are committed already - it comes down to the height...you can bitch about it or except it for what it is and keep battling.
