Balk from a Set or Stretch position

Mel, the pitching maneuver you describe happens all the time. If you carefully read 8.01 of the OBR, you will find that, for a pitcher to disengage the rubber, he must drop both hands and step BACK off the rubber with his pivot foot.
BUT, if the pitcher doesn't do that, there is no penalty for not doing it. Therein is the reason why upires do not enforce the disengagement protocol. As a base upire, I watch that pivot foot like a hawk, because they don't always get that foot completely off the rubber. I nail them for it, because I feel like pitchers push to the limit a rule that has no "teeth in it."
