Thanks so far, guys.. answers to questions... he is leaning heavily toward mechanical engineering but some interest in aeronautical. My son played in same conference as UCSD last year so I think I have a pretty good feel for whether this player would fit at that level. He is a small LH CF with definite D1 speed, excellent defense, great swing mechanics. He definitely has the passion and work ethic to succeed with college ball (although I don't know the extent of added difficulty engineering will present) . Has very good grades but not sure if they quite get him in UCSD. Physical size and arm strength aren't quite at target level for high D2 baseball but getting there. I think he would likely sit as a freshman and then have a good shot at contributing as a soph or junior. Not sure if the size issue would keep him from getting a look with them, in fact I'm pretty sure he has been in front of them - he has played quite a bit with the Trosky program. So, he is even more of a stretch for Cal Poly, although that would be his dream school. That's part of why he is considering JC route. He would be an instant contributor to most decent D3's/ NAIA's. Ceiling is higher but he is very open to smaller schools and understands that it may work better with his major of interest.
My intention was not to do his work for him , just ask my initial question about the JC issue. But since questions are coming, I'm glad to answer what I know to help him with information.
