Although BOF didn't mention it, you might want to consider the school his son and infielddad's son attend(ed) - Trinity in San Antonio Texas. Both kids were from California and from all accounts that I've read here, their son's thrived there academically and athletically. They are also on par baseball-wise with a program like Marietta. I am guessing if Marietta is interested, Trinity would also be if you contacted them. All the best to the young man.
We are indeed in touch with Trinity. Have even talked to a local player from our area who plays for Trinity, while he was home for the winter break. Gave us quite a bit of insight into the program. Trinity is higher on the list than any Ohio school. Son's main challenge is actually getting admitted where he is liked by the baseball folks. Unfortunately, he took awhile getting going in HS. (Let that be a lesson to all. really talented baseball player, started out as in indifferent student, realized he had to pick up the pace only late in the game to get into schools where he was a good baseball fit.)
