Check swings couldnt work, because the bat could go over the spot and there wouldnt be any intent to swing. Check swings are a judgement call on intent, not breaking of the wrists or the bat going past a certain point. Even then its subjective.
Why anyone pitches anything but sliders off the plate to Cory is beyond me. It appears that he is sitting out side of the batters box with as far away his bat is from the ball on them.
When asked about Green DM has said that he thinks he will be a Sept call up along with Gamel. If he was on the list he would have danced around the question, with hyperbole and generalities.
Going off the way Doug has referenced him in regards to his play and a Sept. call up, I can firmly say that its about a 99% chance that he isnt on that list.
If he is nothing else, he is persistent. He has put a lot of effort in to this for it to be a joke. He must have really heard something that he believes. Now whether his source is correct, remains to be seen.
