LOUISVILLE, Ky. — Maximum Security led the Kentucky Derby every step of the way except for the last one — into the winner's circle.
The colt became the first winning horse disqualified for interference in the Kentucky Derby's 145-year history, leading to an agonizing wait and an eventual stunning reversal that made 65-1 shot Country House the winner Saturday at Churchill Downs.
Country House finished second in the slop before objections were raised, causing a 20-minute delay while stewards repeatedly reviewed several angles of video footage before he was elevated to winning status.
That gave Hall of Fame trainer Bill Mott his first Kentucky Derby victory at age 65.
"It's bittersweet. You always want to win with a clean trip and have everybody recognize the horse as the very good horse and great athlete that he is," Mott said. "Due to the disqualification, I think some of that is diminished."
Jockey Flavien Prat, who originated the claim of foul, also won the Kentucky Derby for the first time.
"I'm kind of speechless right now," Prat said, letting out a long sigh.
Country House paid $132.40 to win, the second-highest payout in the race's history.
"Looking at the tote board, there's probably a lot of people that didn't think we could win," Mott said, "but that's horse racing."
Country House was dismissed as a long shot with a bad post on the far outside. It was only the chestnut colt's second win in seven career starts and his first stakes victory.
Maybe this was one for his father: Lookin At Lucky got saddled with the dreaded No. 1 post in the 2010 Kentucky Derby, where he got pinned to the rail and wound up sixth. He rebounded to win the Preakness Stakes two weeks later.
The disqualification was a crushing turn of events for Maximum Security trainer Jason Servis and jockey Luis Saez, who already had begun celebrating. Neither has ever won the Kentucky Derby.
Instead, previously undefeated Maximum Security was dropped to 17th of 19 horses for veering out turning for home and stacking up War of Will, Long Range Toddy and Bodexpress (also owned by the Wests), according to Barbara Borden, chief steward of the Kentucky Horse Racing Commission. Country House, in turn, was brushed by Long Range Toddy.
Sent off as the 9-2 second choice, Maximum Security was placed behind all the horses he bothered.
"I never put anybody in danger," Saez said.
Servis backed up his jockey, saying: "He's right. He straightened him up right away, and I didn't think it affects the outcome of the race."
Prat claimed Maximum Security ducked out in the final turn and forced several horses to steady, including Long Range Toddy, whose jockey, Jon Court, also lodged an objection. War of Will came perilously close to clipping heels with Maximum Security, which could have caused a chain-reaction accident.
"There were two horses in the race that lost all chance to win a Kentucky Derby," Mott said. "They were in position at the time to hit the board. If what happened to us was the only thing they were looking at, I don't think you would have seen a disqualification."
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 while keeping the crowd of 150,729 and millions more watching on television and online in suspense, clutching their betting tickets. Trainers and jockeys involved stared at the closest video screen while waiting for a resolution for the 1 1/4-mile race.
Country House's winning time was 2 minutes, 3.93 seconds.
"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 Kentucky 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 3/4 lengths in front. The stewards didn't change the result.
The only other disqualification in the Kentucky 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.
Country House wore the garland of red roses, but it's possible the situation doesn't end here. There could be appeals to the Kentucky Horse Racing Commission or the courts.
"That's a nightmare. It's a no-win situation for anybody involved," said Mott, who spoke with Servis after the reversal. "I didn't get a hint of that from him. He's been around long enough, and I'm sure he watched the films well enough. He knows what happened."
But Gary West, who owns Maximum Security with his wife, Mary, indicated they may pursue an appeal.
"I think this is the most egregious disqualification in the history of horse racing," he told The Associated Press by phone, "and not just because it's our horse."
Added West: "We are exploring our options to appeal. If we can't appeal to the stewards, our other options are the state racing commission. If those don't work, we might go to legal options."
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 to the ground, frantically searching for their betting slips.
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 Triple Crown of Thoroughbred Racing trail continues with the Preakness Stakes on May 18 at Pimlico Racecourse in Baltimore and the Belmont Stakes on June 8 at Belmont Park in Elmont, New York.
