I found it....
This was back in 2004 in Texas......
The Player was named Guerra who played for Denton Ryan High School. He had a crow hop delivery. His delivery was very controversial. I believe perfect game had a video of him and his delivery.
“It was reported that the delivery had more than a couple of scouts and coaches questioning whether it is legal per baseball rules or not. At least one coach sent in film to the NCAA for a ruling before he decided to start recruiting him. What he did was comparable to what a women’s softball pitcher does prior to release, except with a standard ¾’s release point. He takes a hard, big hop off his back (right) leg at the point when he starts coming forward in his delivery, lands hard on his front (left) leg and completes his arm stroke with his right leg probably a foot in front of the pitching rubber. While every pitcher looses contact with the rubber before he throws the ball, His action is so severe and exaggerated that there is little, if any, precedent for it at this level.”
I remember looking at the utube video and taking the above quote from the young man’s profile. I would have, of course abided by any interpretation that the NCAA would have ruled on, but until that time, I saw the move as a balk....They did as well.....
The pitcher did not continue to use this delivery in college......
