LOUISVILLE, Ky. - The twists and turns of racing were never more evident than in Saturday's 137th Kentucky Derby at Churchill Downs, when trainer Graham Motion, who seemingly lost his best chance for a Derby win earlier in the week when Toby's Corner was withdrawn, and jockey John Velazquez, who seemingly was to sit this one out when Uncle Mo was scratched on Friday, combined forces to win with the 20-1 shot Animal Kingdom, who was making his first start on dirt.
