Say it better II
 

Didnt want to hijack the other thread...

A similar scenario I posted in the past had a batter bunt the ball down, into the soft powder, up in the front corner of the BB, where it comes to a stop (completely in the box, completely in fair territory).

After hesitating, batter realizes its a fair ball, takes off, and comes in contact with the ball (both feet completely in the box).

Has she not contacted a fair batted ball, and (possibly) interfered with the defense's chance of making an out?

Again, NCAA is the only one I'm aware of that states in B&W that if a foot is in the box, it is a foul ball. Which is weird, because it's a fair ball.

The rule makes no distinction about a batter/runner being in or out of the box if they are the ones that initiate the contact with the ball. If the batter runner contacts a fair batted ball they are out. The rule applies to a batted ball that comes back and hits them.

I always look at this as did the ball hit the batter or did the batter hit the ball.

If the former, and it’s in the batter’s box, then foul ball.

If the latter, and it’s fair, then interference and batter out.
