What Brett Cecil was sent to Las Vegas to Work On

I saw a picture from the first few days of spring training, and I saw the odd pitching motion of Brett.

You can see in this picture hes throwing his breaking ball(curve probably, but maybe slider, lol knuckle slider), and its pretty obvious. Most good hitters in the majors would pick up on this pitching motion and be aware of what pitch is coming.

My two cents is that Brett is Vegas to work on this motion and make it less revealing. Some point in May or June he should get a call up to the Jays.
