Darren Beadman completed his astonishing comeback to race riding yesterday in the best possible way, guiding a rampaging Viva Pataca to a last-to-first victory in the Mission Hills Sha Tin Trophy (1,600m). Just two weeks earlier, Beadman was taken from Sha Tin to Prince Wales Hospital after being rudely unseated in the parade yard by a fractious first starter. The champion Australian jockey was initially diagnosed with two fractures in his lower back and the prognosis for his immediate riding future was guarded at best. However, once inspected by a specialist orthopaedic surgeon, the 'fractures' on X-ray were revealed to be shadows from an old injury and the way forward was suddenly might brighter - rest, physiotherapy and anti-inflammatories, leading to a return to trackwork early last week. The dramatic swing of events had an equally amazing finale yesterday when Viva Pataca, resuming from a spell, emphatically staked his claim for a revenge mission in the Cathay Pacific Hong Kong Cup in December. The six-year-old, carrying the colours of Macau casino tycoon Stanley Ho Hung-sun, settled at the tail of the field, gave Beadman an armchair ride into the race before unleashing a devastating change of gears in the home straight to win with something in reserve. 'That was a great thrill today and, while it has come as something of a surprise that he would do that to such a good field first-up, Viva Pataca is such a good horse we shouldn't be surprised by what he does,' Beadman said. 'Going down to the barrier today, it was the most settled and relaxed I've ever known him. I thought then that he was ready to do something serious.' Beadman later completed a double for trainer John Moore when favourite Redragtoabull comfortably won the final event, the Mission Hills Resort Handicap.
