What do you do?

What happens when this fly ball from the other field hits F4 - and you kill it... and they throw out the BR anyway? You cannot call BR out if you've killed a live ball play.

99% of the time, that errant ball is going to have no effect on the play - perhaps a momentary distraction that doesn't change the outcome. But if you kill play when you see that ball fly onto your field, you've just changed the possible outcome.

I agree now.
Just to clarify, I never said just for a ball/object flying in; only if it struck a directly involved player. As said now, not then either.
