LOUISVILLE, Ky.—Medina Spirit’s victory in the Kentucky Derby is in serious jeopardy because of a positive postrace drug test, one that prompted Churchill Downs to suspend Hall of Fame trainer Bob Baffert immediately on Sunday in the latest scandal to plague the sport.
Baffert denied all wrongdoing and promised to be fully transparent with the Kentucky Horse Racing Commission during its investigation. Baffert’s barn received word Saturday that Medina Spirit had tested positive for an excessive amount of the steroid betamethasone, which is sometimes used to treat pain and inflammation in horses.
