You mentioned that you have a GOOD pitching coach. This person is the one you should have this conversation with.
About asking us or anyone else these questions
If you’re going to work with and take advantage of all the knowhow, experience and knowledge of this pitching coach, just be mindful that every coach that I’ve ever known - including me, takes a dim view of having others thrown in a coach’s face with … " but coach, I was told to do this differently…" Ghost coaches are a pain the casabas… to put it bluntly.
Take the time to have a long conversation with this pitching coach and tell him exactly what you mentioned here.
Best wishes with your baseball experience.
