Smoke;
Help your son to teach himself. Read about the great pitchers, Nolan Ryan, Bob Gibson as to their training methods. Many years ago during our Area Code tryout at Texas A&M, I met Ralph Garr, Scout with the Braves and former National League batting Champion.
I ask Ralph "who was your hitting instructor"? He said "Henry".
I ask "What did Henry Aaron tell you"?
Henry said "figure it out for yourself".
When a pitcher is on the mound, no one can help. He has to rely on his ability.
