There is no stepping out rule in LL Jrs. I do tell them not to get too far away. If they start walking way away from the box I tell them to stay in in the vicinity. In PONY there is a stepping out rule but no penalty. If the batters start the holding the hand up thing to get back in box I tell them I won't let the pitcher quick pitch them but I'm not calling time every pitch for them because it takes the pick-off ability away from the pitcher.
