Don is right in that you can't straddle the rubber and bring your hands together pretending that you are coming set. That is a motion associated with a pitch, and is prohibited. Merely joining the hands together is not prohibited, but if you think the pitcher is trying to deceive the runner into believing that he is actually on the rubber, then it is a balk. But just transferring the ball in and out of the glove is nothing..

Thank you.
I've tried all along to make the point that simulating the pitching motion, whether stretch or set is the issue, not the act of fondling the ball in the glove.

Here's where I'm going to nit pick, because that's how this all started, with me nit picking.
He started his stretch while not on the rubber, I believe that constitutes a balk. I don't believe in calling it, but it is a balk.
