I doubt that any of his problems have been physical. Hes simply worth too much as a stallion to risk on the track broken down. Hes a grade one winner who placed in the BCC to a horse of the year at age three, and his sire is the hottest thing on the planet.
I think it was also obvious that his problems weren't physical in nature(to the extent that he would run that poorly, may be aches and pains but they aren't the full story) after they didn't immediately retire him after the dreadful performance he put in at Saratoga, the Woodward being just awful for him.
It appears as though hes lost his desire to compete to me. He travels smoothly enough and was working well at Saratoga before both races. He simply didn't show any punch at all on the track. If he did indeed fire a bullet(I have no knowledge of this, hes not in my stable mail) then perhaps they will try the Cigar Mile.
