Last night at a female fast pitch game (16U), the pitcher pitched a pitch which she called "chinese Change-up". She started on the rubber with both hands together; however she brought the ball behind her hip and instead of bringing her arm around in a nomal fast pitch rotation, she pitched the ball stright foward in a slow pitch method. The ball flowed to the plate with a slow pitch arce (about 5 feet) on it. The umpire called it lllegal pitch. Her team coach argue that it was legal; however the opposing team coach called it lllegal, also.

Has anyone heard of this pitch and is it legal according to ASA rules?

What is illegal about the pitch? If I am reading this correctly, and I have made
the portion bold that I am questioning, is the fact that she starts with both hands
together.
