Pitching mechanics question

[kcs_hiker]

I had the plate. Senior night big crowd for both teams. Home pitcher was a freshman, good pitcher, lefthanded with some movement. Anyway, right before she releases, her pivot foot lifts maybe an inch or two off the rubber. I had the same team in previous game (I was in the field) and I noticed it then and asked the plate ump about it and he said he wouldn't call anything since she wasn't really gaining an advantage. Before this game I noticed it when she was warming up, and I asked the coach if anyone had called her on it. He said no (yes I know he would say that, but he seemed sincere). I let it go.

Bottom of the 7th, score tied 1-1, same pitcher is on 2nd, 1 out, batter bunts, runner on 2nd tries to score after the out at first and is out by a mile, and injures herself sliding (she slid head first and probably seperated her shoulder, non pitching arm). Top of the 8th, the girl comes out to pitch, she can't hardly raise her arm but she's game and can still pitch. Visiting coach calls time before the first batter steps in and guess what she wants me to call? Yep, she wants me to call illegal pitch when she lifts her foot. I told her I wasn't going to, that she would have had a legitimate complaint in the first inning but not in the 8th. She grumbled something about writing me up, and left.

Girl strikes out the side in the 8th, home team scores in the bottom and wins. I take the long way around to my car to avoid visiting dugout.
