If the batter misses the pitch on a bunt attempt and catcher catches the ball and try to tag the runner stealing home but runs into the batter when going for tag. It's my understanding that if the batter don't move, interference wont be called. If batter moves, even if he is trying to get out of the way, and catcher runs into him it is interference. 13U USSSA rules. I just wanted to know what is the real rule on this.
