Medina Spirit, who won the Kentucky Derby on May 1 to give the trainer Bob Baffert a record seventh victory in the race, was installed as the 9-5 morning-line favorite in Saturday’s Preakness Stakes, despite nearly not running at all after it was disclosed that he had tested positive for betamethasone, a corticosteroid, after the Derby.
While officials in Kentucky awaited results from a second sample before determining whether Medina Spirit’s Derby victory would be overturned, Preakness organizers on Tuesday announced they would let the colt run after Baffert and his lawyer agreed to expanded testing and monitoring of his horses in Baltimore.
