I saw the same thing. Looked like he was uncomfortable. I wonder what he was sucking his thumb for. Wouldn't be surprised to see the line drop a touch just because of the piece. It's probably nothing........if it was, further word would probably be circulating.
They were showing him having problems throwing the ball and holding his thumb on his throwing hand, trying on different gloves and still grimacing (SP) in pain. He says no problem, but thats not how it looked!
