Kentucky Derby winner Medina Spirit has tested positive for a banned race-day drug, its trainer announced. Bob Baffert, a Hall of Fame trainer, announced in a press conference at Churchill Downs Sunday that the horse failed a post-race drug test. Medina Spirit was found to have 21 picograms of the steroid betamethasone, which is double the legal limit in Kentucky racing, Baffert said. On May 1, Medina Spirit won the Kentucky Derby by a half-length. Baffert's team learned of the positive result from Kentucky officials on Saturday, he said.
