Position in batters box

Question
In junior league or any other league for that matter is there a rule that states that the batter must have both feet inside the batter's box prior to the pitch?  Just wondering because I thought that this was a rule but tonight's umpire said that it is not a rule.  The other team had kids standing with their forward foot out of the box and in the playing area because their coach told them it was the only way they could hit our pitcher.

Answer
Jerry,

Rule 6.03 states that "the batter抯 legal position shall be both feet within the batter's box."  

Remember that the lines of the box constitute the box, and the batters entire foot must be outside the box before this becomes a violation.  

For example, half of the batter's foot is outside the box.  He is still considered inside the box.  However, lets say that his entire foot is on home plate, then he would be in violation of this rule, and the umpire will instruct him to take a stance in the box.

I hope this has answered your question.  Should you have any more, please don't hesitate to ask!
