NEW ORLEANS - It was the best of times, it was the worst of times for young Peruvian jockey Miguel Mena. On July 30, Mena won the Sanford Stakes aboard Backtalk, a breakthrough graded stakes victory on the big stage at Saratoga. Two mornings later, he slept through a flight that was to take him from New York to West Virginia for the West Virginia Derby at Mountaineer Park. The horse he was supposed to ride, Soul Warrior, won the race for trainer Steve Asmussen. And the whole racing world seemed to know about Mena's misstep.
