bballpitcher32, please first ask yourself why you are going to college, and what you can afford.
If you can afford a finer college, I would recommend you either give up the baseball or walkon. Just being realistic given the size/velocity you stated. If you cannot afford a top college, you should focus on some local JC's where you might develop, add some height/weight/strength/velocity.
BTW, height is not the serious issue in your case, but the COMBINATION of RHP/lower velocity/smaller size is definitely a tough draw. Just being realistic. On the other hand, don't let anyone--including me--tell you you can't do something. Good luck.
(Note to Homerun04: The Arizona Senior Fall Classic is a dud compared to the Junior Fall Classic. The scouts are at the Jr. event. The senior event is mainly pro scouts and some JC's. Been there, done that.)
