I like the move. As many have mentioned, they are probably going to try and completely breakdown and fix his swing. Going through all of that and feeling the initial discomfort while at AAA (facing better pitching) he could go through the same struggles he is now and just resort back to his old ways. I'm hoping that they send him down there,until they feel he has checked all of their boxes, and then send him to AAA to make sure he sticks with their corrections before bringing him back up.
