I'm betting OBR and NCAA is the same.

I would doubt that because the batter is free to switch from which side they want to bat from in between each pitch. I know the rules aren't meant to be fair but it would seem strange that the batter is free to choose which way they want to hit the ball for every pitch but the pitcher has to declare for each batter??? Doesn't make sense. (Which doesn't mean it isn't true!!)
