Not really sure what the point of this post is. Let's not take it out of context-it's not as if his reaction was unprompted.
The kid pitches a gem. He comes out of the game for the 8th b/c he tweaked his back earlier (snagged a spike). A camera happens to catch a shot of him showing his hand to Nipper and a trainer. His finger, for the record, was fine.
All of a sudden its all "BECKETT HAS BLISTERS AGAIN!" It headlines DirtDogs, with all the back quotes about how they can't seem to fix the problem (from past years, mind you), it's on the Globe, NESN pulls up the graphic of his DL stints due to blisters, Remdawg announces his suspicion. Hell, there's even some clown over on injury/player updates who instantly posts a thread "Beckett and Blisters! Beware!!"
Then he comes out and rather than discussing the incredible game he threw (after struggling in recent outings), he's bombarded by speculation that he's back to his old problems. He came to Boston knowing that everyone doubted his ability to stay off the DL because of his finger.
He's an emotional guy, and you can bet that so far, he's been quite proud to be able to prove them wrong and show that he can bring his stuff to the team without concern. It's a lot of pressure, and it sucks that the media won't let him rise above his reputation-even when he IS ok. Screw it. I'd blow up too.
