The trainer of Kentucky Derby winner Medina Spirit on Sunday said that after the race, his horse tested positive for betamethasone, a corticosteroid banned above a certain level in racing.
Bob Baffert, who appeared with his lawyer, Craig Robertson, for a press conference at Churchill Downs, said his team has been informed that Medina Spirit was found to have 21 picograms of the steroid betamethasone, double the legal threshold in Kentucky racing. He called the finding “shocking” because he says Medina Spirit has “never been treated with betamethasone.”
