My son is new to pitching at the HS level so we’re not sure what the rules are for making a pick move towards first base as a right hander. I believe that you are supposed to step behind the rubber and show intent to be moving towards the base.
What are the specific things, either in the rule-book or accepted by most umpires, that govern what you can and cannot do?
I ask because we are working on a quick move that happens right as the pitcher “sets” which is designed to get runners just as they typically lean or take their secondary steps towards second base. It is very effective but not worth a balk and giving the runner the base for free.
