This is a point of confusion for me. I remember my first year, my third strike mechanic was the same as my first or second strike. I did not alter my ball four call either, resulting in a few batters that I would have to remind that it was either strike three or ball four. I received the advice, either on here or from a partner or perhaps an ASA school, to make the call "strike three" or "ball four". I have done it that way, including pulling a bow, for the last two years. Even got compliments last year at a state school for my third strike mechanic. Fast forward to this year, attending another state school, and I'm next to last in my group to get behind the plate. No one else has verbalized a "three" as part of their mechanic, but when I'm asked to break mine out, I stick with my "strike three". The "three" is barely out of my mouth when I'm descended upon by both instructors telling me not to call out three. So now I'm back to being confused again, wondering exactly what it is that I'm supposed to be doing while I rework my mechanic again.
