When my son was in HS one of our main rivals listed all of their coaches, including a mental conditioning coach (Wealthy district).
Son generally is very mature and able to channel his feelings while pitching — when he gets mad at the other team he'll gain a couple of miles on his fastball and is generally very controlled. HIs biggest downfall is when he gets mad at himself.
His coaches since grade school have told him he needs to stop thinking.
Would a mental conditioning coach help with that? It doesn't seem like any of his coaches have suggested this — is there a stigma to using something or is it something I just need to let him work through on his own? I believe his college has one, but I'm not sure what is involved in getting access to it.
