Pitcher balk ?- throw to 1st

[DUNDALKCHOPPER]

Thanks everyone.. Saw Verlander twice yesterday throw to 1st while simply spinning on the non-pivot foot while simply lifting the pivot foot.
.
My other Balk beef is when a pitcher brings the non-pivot foot over top of the rubber then throws to 1st. I was also under the impression that once that happens the pitcher must pitch or spin around to make a play at 2nd.- I know its another topic :-)
