** FILE ** In this May 3, 2008 file photo, Kent Desormeaux rides Big Brown to a victory in the 134th Kentucky Derby Saturday at Churchill Downs in Louisville, Ky. Big Brown figures to produce big green as a stallion, which is why the Kentucky Derby winner almost certainly will retire young. The trend of short racing careers may be lucrative for breeders, but some in the industry question whether breeding for speed rather than durability is making the sport more dangerous.
