LOS ANGELES—Medina Spirit, the Kentucky Derby-winning horse that failed a drug test afterward and cast a cloud over the victory, died Dec. 6 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.
