LOUISVILLE - Great White, who flipped behind the Kentucky Derby starting gate and was a late scratch, emerged from the incident without serious injury, as did jockey Alex Achard.  Trainer John Ennis said Great White was “perfect” following the incident. The gelding was vanned from Churchill Downs back to the trainer’s base at the Thoroughbred Training Center in Lexington on Sunday morning.    Great White, a massive gelding who weighs nearly 1,400 pounds, was waiting to load in one of the outside posts when he spooked, reared, lost his balance and went back on his hindquarters, and then rolled over backward. He sprang to his feet and a Churchill Downs outrider immediately and adroitly snagged his reins. Achard fell clear when the gelding went down, jumped to his feet, and walked back under his own power. After waiting out the Kentucky Derby in the paddock, Great White walked back to the barns with the rest of the field.  Because the majority of the Derby field had already been loaded, they were backed out while the gate crew adjusted for numbers and the now-open slot in the gate, and then reloaded. Eventual winner Golden Tempo was not yet in the gate when Great White began to act up, and jockey Jose Ortiz said he asked his handler not to load him yet, which proved a wise decision as Golden Tempo did not have to be loaded twice.  :: Access the most trusted data and information in horse racing!

He would have been the second Derby runner for Ennis - who finished 14th with Epic Ride two years ago - and the first for Achard.  :: Want to learn more about handicapping and wagering?
