Mott said the incident was caused by Maximum Security's action and not Saez's riding tactics.

"I don't think Luis Saez did anything intentionally," the trainer said. "My heart actually aches for them a little bit. That's the way it is. I've been on the other end of it, just not in the Kentucky Derby."

The stewards reviewed race footage for nearly 20 minutes while keeping the crowd of 150,729 in suspense, clutching their betting tickets. Trainers and jockeys involved stared at the closest video screen waiting for a result.

"I know the stewards had a very, very difficult decision," Mott said. "I'm damn glad they put our number up."

Code of Honor was moved up to second and Tacitus — also trained by Mott — was third.

Improbable was fourth and Game Winner fifth, two of trainer Bob Baffert's trio of entries. His other horse, Roadster, was 15th.

The last claim of foul by a jockey in the Derby was unsuccessful. John Velazquez, aboard runner-up Invisible Ink in 2001, alleged interference at the quarter pole against Monarchos and Jorge Chavez, who crossed the finish line 4? lengths in front. The stewards didn't change the result.

The only other disqualification in the Derby occurred long after the race in 1968. Dancer's Image, the first-place finisher, tested positive for a prohibited medication, and Kentucky state racing officials ordered the purse money to be redistributed. Forward Pass got the winner's share. A subsequent court challenge upheld the stewards' decision.

Master Fencer, the first Japan-bred to run in the Derby, was sixth. War of Will was seventh, followed by Plus Que Parfait, Win Win Win, Cutting Humor, By My Standards and Vekoma.

Bodexpress finished 13th, followed by Tax, Roadster, Long Range Toddy, Maximum Security, Spinoff and Gray Magician.

The surprising flip threw a few bettors into a frenzy, too. Some who had wagered on Country House to win immediately tossed away their tickets at the finish, only to then scramble on the floor of the stands at Churchill Downs, frantically searching for their betting slips.
