Not in contact with rubber at release??

I assume you're talking about Javy Guerra. If so, I would describe it as a little crow hop as he strides. He definitely re-plants his right (pivot) foot before he releases the ball.

There was a lot of speculation about if his mechanics would be considered legal by pro umpires. He has signed and made his debut the other night in the Gulf Coast League (Rookie). I haven't heard anything about him having to change things, so they must've allowed it.
