When is a Batter out of the Box?

[Manny A]

Hmmm... Perhaps I've been using the wrong criterion to make the determination if the batter contacts a fair ball. I've always believed that we give the benefit of the doubt to the batter if she contacts the ball while she's still in the box, since it would be very difficult at that point to judge where the ball was in terms of fair or foul territory.

But if we can tell beyond a shadow of a doubt that it was fair when she touched it as she was leaving the box, it doesn't matter where she is in relation to her feet and the box? That's good to know; I've probably given away too many outs in my days!
