A good hitting coach is going to talk a lot about this too. Approach can be screwed up too! LOLDD's hitting coach wants to see every AB from a tournament. I video them all and send them to him on Sunday evening. He uses them to help make a plan for next lesson. I even send him video of BP at practice if DD is struggling.
He made rounds to several of his students tournaments this weekend. He was at 1 game for DD Saturday. Think it was his 4th location of the day.
Team we just left, bunch of daddy coaches, always gave DD horrible hitting advice. (the were great coaches at most things, just not hitting) One even said "squish the bug" once. DD knew just to nod her head and do what she knows is right.
Just joined a new team and they told us up front that if DD was seeing a hitting coach they would not mess with her swing. They will talk to her about approach to an AB but not mechanics.
