Who would you say is the best pitching coach on the east coast for a 18 year old pitcher
That’s a question nobody can answer. Everyone needs their own coach who can help you perform at your best.
Very true. To paraphrase an old saying, “What’s sauce for the goose is not necessarily sauce for the gander”, and different pitchers have different requirements. So you have to think about what your requirements are, what you want to accomplish, and look for a pitching coach who will work with you to help you make the most of what you have and can do.
