I was brought up calling the person batting behind the on deck batter was, "In the hold." On the Gameday coverage of the Astros game today they have "In the hole." Which one is it?

When I was nine or ten our coach made us say, "In the hold" and said it had something to do with the hold of a ship.

Does anyone know the answer to this. I breifly looked it up on the internet and really got no definitive answer.
