Seems you are asking whether the coach is making good decisions. Answer is likely no.
But is your daughter making good decisions?
Not judging. You are there, not us. But I do think it's fair to ask --
Should DD be having non-verbal communication with a parent during a game? Is her body language negatively affecting the team? Could your daughter have a calm, respectful conversation with the coach about how she doesn't trust his pitch selection and how they can work together to make the team better? Is DD being discouraged from that sort of solution by any validation she might get when looking in the stands, or by hearing her mother's comments when she is pulled? What would you want to teach her about handling problems with people in authority?
Why is she still playing for this guy?
