Thank you for the responses. BBscout, good question, and yes, he does have things in order for college. He went to one showcase and a few college camps and then made a list of schools with good baseball programs that seemed like possible matches. Then he chose a D3 from that list based mostly on the school, not baseball. But they have a good baseball program and the coaches have said they want him. He has never written letters to other college coaches and is happy with his D3 choice, has been accepted by Admissions, etc.
He has been called projectable and other positive comments about his body type and potential by a couple of pro baseball people and a D1 coach, but at his previous velocity in the 70s he did not attract serious interest from D1 colleges or pro scouts. I think the draft is still unlikely to involve him in the near future, but I was just curious. He will hopefully continue to develop in college and have some opportunities in a few years.
Thanks again.
