Medina Spirit was stripped of the victory in last year’s Kentucky Derby and Mandaloun was declared the winner after a ruling by state racing stewards on Monday.

The since-deceased Medina Spirit tested positive after the race last May for a steroid, betamethasone, that is legal in Kentucky but banned on race day. The positive test threw the world’s best-known horse race into turmoil and cast an unflattering spotlight on trainer Bob Baffert, considered the face of horse racing after he guided horses to the Triple Crown in 2015 and 2018.

Medina Spirit finished half a length ahead of Mandaloun in the race, giving Baffert what was then his seventh Kentucky Derby title. Baffert was subsequently banned for two years by Churchill Downs following the positive test.

Monday’s decision by the Kentucky Horse Racing Commission makes Medina Spirit the second horse in the 147-year history of the race to be disqualified for a banned substance; the first was Dancer’s Image in 1968, a decision that gave Forward Pass the victory. The only other disqualification was in 2019 when Maximum Security was penalized because of interference, giving Country House the win.

Following the announcement by the racing stewards, Churchill Downs issued a statement declaring Mandaloun the Kentucky Derby winner and congratulating owner and breeder Juddmonte Farms, trainer Brad Cox and jockey Florent Geroux.

Cox becomes the first Louisville native to win the Derby, and Mandaloun’s owners will receive the $1.8 million winner’s purse.

“We look forward to celebrating Mandaloun on a future date in a way that is fitting of this rare distinction,” the statement said.

The track plans to replace Medina Spirit with Mandaloun on the paddock sign honoring the Derby winner on Tuesday.
