This is exactly my rationale.

It keeps the idiot in the outfield from yelling, "Hey, Blue, what was wrong with that...It hit right square in the middle of the mat!"

Some of my umpires make plenty of other signals like waving the hand over the head for a pitch that is too high or holding out their hand flat for a pitch that is too low, bu they can't be bothered to make the proper signal?
