I've read the rules, and I'm pretty sure I'm interpreting the alteration part right. You are certainly entitled to believe otherwise, but that's your opinion. I never said the rule specified what I put in quotes I just gave examples of what an alteration might be or what I thought an alteration would be interpreted as. But it did say .'He shall not raise either foot from the ground, except that in his actual delivery of the ball to the batter, he may take one step backward, and one step forward with his free foot.' Those sure SEEM like examples. And it continued from there in that paragraph on things that could and couldn't be done to be considered a windup. It wasn't called, so apparently the umpires also don't think he altered his delivery in the context of the rule either. Also, you seem heck-bent on saying it's a balk, so why start a thread to ask people their OPINIONS if all you want to do is shout down anyone saying other-wise? You're interpreting what they mean by alteration one way, others are doing it another, but those others are doing it wrong, apparently. The only way to interpret the rules correctly is to conclude it was a balk? It wasn't a balk, IMO.
