(CNN) Kentucky Derby winner Medina Spirit has tested positive for elevated levels of betamethasone, trainer Bob Baffert revealed Sunday, throwing the horse's victory last weekend at Churchill Downs into question. Betamethasone is an anti-inflammatory corticosteroid that is allowed in horse racing at a certain level. But Baffert said he'd been informed that Medina Spirit's postrace test detected 21 picograms per milliliter -- more than double the legal threshold in Kentucky racing. "We will await the conclusion of the Kentucky Horse Racing Commissions' investigation before taking further steps." Bob Baffert talks to reporters before the 145th running of the Kentucky Derby at Churchill Downs in 2019 in Louisville.
