This weekend at an 12:U tourney with a runner on first and a left handed pitcher on the mound. The pitcher gets the sign from the catcher and starts his motion. Before he comes set (in mid motion) he throws over to first (without stepping off the rubber). When asked the umpire said it was not a balk because he did not have to come set as long as he was throwing to first. Now, I know pitchers can make a throw to first but I thought once they started their motion they had to come set or step off the rubber.
What's the rule?
