I understand a pitcher can vary speed of delivery. We are talking about starting/stopping delivery or adding in steps which are not allowed according to 8.01 which is not dependent on runners.
And I know what you meant by real, and I know what Rule 2.00 says. Since it didn't reference Rule 2.00, and a whole page had been taken up describing what IS legal, I just assumed that doing things 8.01 says not to do was illegal, and would be covered in 8.01(d). It seems that is not the appropriate interpretation. I would still like to know how to handle a situation where the pitcher does something not legal, like start-stop-start a pitch or take too many steps, and then delivers a pitch. The fact that both pitch deliveries require that once you start the pitching motion you must complete it without "interruption or alteration" matters and should be enforced. The batter should not be put in jeopardy of a strike or out if the pitcher is not following the rule. Is it just a no pitch, resume count?
Obviously this happens mostly in lower levels. I have not seen it in juniors, seniors, or school ball, but that doesn't mean it's not possible. But it still seems like something that would need to be addressed. If not as an IP/ball called, then however. Thanks for the replies.
