If it is salvageable I would proceed with caution. And have a very serious and direct talk with the coaches. I have seen coaches that stay in their lane and try to find useful ways to help make small suggestions to help if struggling. I have also seen coaches not use the player or put them in bad situations to try and prove they were right. If the coaches give you any vibe that they feel it’s my way or the Highway then exit stage left quickly. It will not be a good situation. If they will be happy with the smile and nod technique then the pitcher just has to produce. Some things that could be a problem in this situation are drills and other work at practice. Some drills used in both hitting and pitching can teach bad habits if there are different philosophy then the coaches. I believe in trying to fit in and do what the coaches want at practice but if there is something obvious causing a problem or bad habits then the coach needs to be approachable and willing to work with you to change the drill for your DD or have alternate drills.
