The Jason Servis-trained colt crossed the line first in a soggy race Saturday, but was adjudged to have illegally impeded other horses during a feisty encounter.
Second-placed horse Country House, at odds of 65-1, was elevated to champion, becoming the second biggest longshot ever to win the historic race.
Backers of the horse were also ruing missing out on their share of the $42 million bet on the race with TwinSpires.com, the official wagering site of Churchill Downs. Of that total, 82.5 percent goes back to winning bettors.
The Derby is the first leg of the famous Triple Crown, which moves on to the Preakness Stakes at Pimlico Racecourse in Baltimore on May 18 before the final leg at Belmont Park, on Long Island on June 8.
Only 13 horses have won the Triple Crown, starting with Sir Barton in 1919, making it a highly sought-after prize. Even being able to put Kentucky Derby winner on a stallion’s resume greatly enhances future stud fees.
In the immediate aftermath of the race at Churchill Downs Saturday, chief steward Barbara Borden read a statement to the media, revealing all three stewards agreed to penalize Maximum Security based on interviews with jockeys and after reviewing video footage.
West also told NBC that Maximum Security wouldn’t be running in the Preakness.
“I think there’s no Triple Crown on the line for us and there’s no reason to run a horse back in two weeks when you don’t have to,” he said.
It was the first time a Derby winner was disqualified because of a foul on the track. In 1968, Dancer’s Image won but failed a drug test and was disqualified.
President Trump tweeted Sunday: “The Kentucky Derby decision was not a good one.
“It was a rough and tumble race on a wet and sloppy track, actually, a beautiful thing to watch.
“Only in these days of political correctness could such an overturn occur. The best horse did NOT win the Kentucky Derby — not even close!”
Country House’s trainer Bill Mott, who got his first Kentucky Derby win, said: “I know the stewards had a very, very difficult decision and I’m glad I wasn’t in their shoes.”
The outcry was no comfort for bettors who staked nearly $10 million on 9-2 second favorite Maximum Security to win, place or show, according to Ed DeRosa of TwinSpires.
One bettor thought they had won $44,000 from an $8,000 stake on Maximum Security before the disqualification, DeRosa told CNN.
Country House attracted just over $918,000 in bets. One lucky backer of the eventual winner scooped $165,500 from a $2,500 stake.
