Can't blame the organization. He was as good as gone after this year anyway. He was listed as being on the DL in AA so no chance he was going to be back in the bigs with the Jays unless he had a miraculous recovery and/or the pitching the Jays had ahead of him completely fell apart.
I'm sure he tried to work his way back up since he was a fairly good starter, then an All Start, then had some injury issues. He probably would wanted to prove the critics wrong and get back on the 40 man roster, and show he was more than a waste. But like mentioned, he probably will catch on elsewhere and wind up an Ace lol That always seems to happen with the Jays. A player falls from grace or stays injured/doesn't produce, is let go, winds up a decent or better player elsewhere. But seeing as he's 30 now it's going to be tough. But as often said in baseball "if you're left handed and breathing you have a chance." If another club doesn't pick him up, he could go to the independent leagues and see if he can still pitch. Someone might take a flyer on him. It seems like he fell apart physically and mentally at the same time since it wasn't reported he had any major (ie TJS) type injuries just nagging leg/knee issues.
I wish him the best. I hate seeing players have to end their careers injured. That being said, he made millions, had some good years with the club, so better than many have done or could have done. Not a surprise he was going to be let go. How else would he have taken it? Get mad and stomp his feet? He knew he had a snowball's chance making the Jays again and was injured so he'd stand a better chance elsewhere. Watch him wind up in San Diego's organization.
