UPDATE: LOUISVILLE, Ky. (AP) — Maximum Security’s owner says horse will not run in Preakness; will appeal Kentucky Derby disqualification.

PREVIOUS STORY: Country House, jockeyed by Flavien Prat and trained by Hall of Famer Bill Mott, was named the winner of the 2019 Kentucky Derby after it was ruled that post time favorite Maximum Security had bumped him significantly enough to change the outcome of the race.

Maximum Security crossed the finish line a length and a half ahead of Country House, but just after the race, officials began reviewing tape. For the first time ever, the horse that made it to the wire first was disqualified.

After the post position draw, Omaha Beach was the early 4-1 favorite with jockey Mike Smith aboard, but scratched after an entrapped epiglottis made breathing difficult for the morning line favorite. Bodexpress moved into the race as the No. 21 horse after the scratch.

Hall of Famer Smith, who initially passed on riding Bob Baffert’s horse Roadster, accepted a ride on Cutting Humor who finished .

It may have been the 145th Run for the Roses, but there were several firsts. Koichi Tsunoda‘s longshot Master Fencer became the first Japan-bred horse to run in the Derby. At the age of 58, Long Range Toddy’s jockey Jon Court became the oldest person to ride in the Kentucky Derby.

Maximum Security will go for the second leg of the Triple Crown at the Preakness Stakes on May 18 on NBC and the NBC Sports app. The 151st Belmont Stakes will round out NBC’s coverage of the Triple Crown on June 8.

Last year, Baffert’s horse Justify won the 144th Kentucky Derby at Churchill Downs with Mike Smith. Owned by WinStar Farm, he become the 13th horse to win the Triple Crown and Bob Baffert’s second, coming just three years after American Pharoah’s 2015 campaign.
