Kentucky Derby winner Medina Spirit dies during workout

Medina Spirit, the Kentucky Derby-winning horse that failed a drug test afterward and cast a cloud over the victory, died Monday during a workout at Santa Anita race track. "Following the completion of a routine morning workout, Medina Spirit collapsed on the track at Santa Anita Park and died suddenly of a probable cardiac event according to the on-site veterinary team who attended to him," track officials said in a statement. The horse, trained by Bob Baffert, won the Kentucky Derby in May but later tested positive for the steroid betamethasone, leading to challenges to the validity of the victory. Officials at Churchill Downs announced that Medina Spirit would be disqualified if the test was confirmed, and it suspended Baffert for two years.
