1) Is there any Fast Pitch rules set that allows what we call the "slip pitch," where the pitcher does a backswing, releases the pitch on the upswing then completes a full rotation after release. I know it is illegal in ISA, NSA, and NFHS. In a WFC game this weekend, I saw one not only thrown for a strike, but when the pitcher game up to bat at the beginning of the next inning, the umpire complimented her on her change up (meaning that pitch).

2) I started to post this under the "Cat" topic, but... what would indicate to you a flagrant enough crow hop to call an illegal pitch? Seeing the "pivot" foot pivoting again as the pitcher pushes off again? Seeing a cloud of dust as the "pivot" foot replants?
