Fair or foul

[oyaisee]

4.03 When the ball is put in play at the start of, or during a game, all fielders other than the catcher shall be on fair territory.

(a)The catcher shall station himself directly back of the plate. He may leave his position at any time to catch a pitch or make a play except that when the batter is being given an intentional base on balls, the catcher must stand with both feet within the lines of the catcher’s box until the ball leaves the pitcher’s hand.

PENALTY: Balk

I read this as a Balk is the penalty!!!!! for all of 4.03 that is what I will call in my games!!!

If it's not a balk then what is it? what is going to make them stop breaking the rule every rule has a consequence it has to or else it is a moot rule!!!!
