dropped third strike

[O.T.Hill]

I should add that I meant to pose this question in the situation where the pitch may or may not be strike 3. Most of you understood that, I think. Thanks for the responses. I guess my main question is, if I do not think the batter swung, and the ball caroms off the catcher, the batter is sort of doing a dance like he may or may not decide to run to first - do I IMMEDIATELY appeal to the BU ? Mr. Jenkins says yes.
