Welcome, I would find the best HS senior in your area and ask who he took lessons from. Sign him up for lessons. Second get on a good long toss program now. While your son is not a pitcher I witnessed a player (C.F.) drafted in the 10th round last year who the scouts say would have been first round if he had a plus arm. I also agree a second position could be important however I have a D1 coach friend who recruits C, P, SS and CF only. So if he is an outfielder CF is a good spot. For now get him on the best team with a top organization as possible. Good luck, have fun!!!
