TRAINER David Hayes is back in Melbourne for the Spring Carnival but it didn't stop him training an impressive double at Sha Tin yesterday. Sprinter Shinnecock Hills (8-1), who looked a certainty beaten on the dirt at his first start, is a horse with a future here as he showed with a spectacular success in the fifth event. Betting was dominated by topweight Hussar (3-1 favourite) and Winning Spirit, who went off at the same quote but it was Shinnecock Hills who burst through with a withering finish to score decisively. Shinnecock Hills has an exciting turn of foot and Piere Strydom, who produced him late, quickly collared Hong Kong Supreme (9-1), who had looked briefly the winner. Winning Spirit, who had been hiked right up the scale after his last success, was worried early in the run by Duet Danseurs and that did not help his cause. Hussar, who beat only one home, was sent for a veterinary check amid reports of a wind problem. The David Oughton-trained favourite had been up with them early but was quickly done with in the straight. Shinnecock Hills is an exciting addition to the sprinting ranks here and, on this effort, will be winning more races in the near future. It had been a brilliant ride on Gints To Win by Mick Kinane that thwarted a first-up success for Shinnecock Hills so Hayes turned to the Irish champion for his stayer, Champion Mascot (8-1), in the 2,000-metre, Class Four fourth event. Hayes was rewarded with another pearl of a ride from Kinane who brought Champion Mascot smoothly through from near the rear to win going away from the Tony Cruz-ridden Gold Concept (6-1). It was an ice-cold, precision ride and Champion Mascot responded in the straight to win decisively. English ace Darryll Holland burst out of a quiet spell to land a 60-1 double on Sharp Racer and sprinter Chater Sovereign. Both horses were prepared by retaining trainer Geoff Lane and Sharp Racer (12-1) was losing his maiden status after 13 starts. Holland deserved real credit for his efforts on the five-year-old in the opening event on the card as he ducked in and then out in the concluding stages of the Class Six, 1,600-metre event. Holland got him back on an even keel and in the final stride edged out Celestial King (20-1) by the minimum margin. Strydom was on Celestial King and attempted to make all on the Hayes-trained galloper who has been a disappointing type. Only the narrowest of short heads prevented a Hayes treble and a double for the South African jockey. Chater Sovereign (5-1), who had been in the frame at his last two starts, won the sixth event quite commandingly. Holland, making full use of his good draw against the rails, asked the Irish import for a real effort about 300 metres out - and got it. Steven King and David Hill combined for an upset win in the eighth event with Manor Lord (20-1) taking the 1,400-metre Class Three event narrowly from Golden Prosperity (5-1), also ridden by Kinane.
