Medina Spirit had won the Kentucky Derby last May, but a failed drug test put the victory in question and led to the suspension of trainer Bob Baffert. The horse was found to have tested positive for 21 picograms of betamethasone, which is permitted unless it is found in the horse’s blood on race day.

Baffert explained on May 11 that 21 picograms of betamethasone in the post-race Derby sample may have come from a fungal ointment meant to treat dermatitis. But there was a debate over whether the betamethasone came from a topical ointment or an injection.

The Board of Stewards on Monday determined there was a violation.

As part of the ruling, Baffert was suspended for 90 days and fined $7,500.

Clark Brewster, Baffert’s attorney, released a statement on the ruling.

"We are disappointed by the Commission’s ruling, but not surprised. This ruling represents an egregious departure from both the facts and the law, but the numerous public statements by KHRC officials over the last several months have made perfectly clear that Bob Baffert’s fate was decided before we ever sat down for a hearing before the three stewards, one of whom is directly employed by Churchill Downs as the racing director at Turfway Park. We will appeal, and we will prevail when the facts and rules are presented to detached, neutral decisionmakers," the statement read.

The thoroughbred died in December after a workout at Santa Anita Park in California.

Owner Amr Zedan told Thoroughbred Daily News the horse suffered an apparent heart attack after a workout. California Horse Racing Board equine medical director Jeff Blea told the website he saw a video of the workout and it appeared the colt had trouble breathing.

Blea said by the time a veterinarian reached Medina Spirit, the horse had already died. Santa Anita spokesman Mike Willman also confirmed the horse’s death.
