As the umpire, why would you care what kind of pitch it is?
I think Andy has it right - there's too many other things you should be concentrating on - like if it's in the zone or not, or if that was a legal pitch or not, did the batter commit when she squared to bunt, etc.
Generically answer the coach's question. If he wants your opinion on his pitcher's movements, then your pitching instruction rate is $xxx per hour, and we'll discuss that after this game.
