David Hayes produced Dwayne Dunn and Cyber Gulch free of injury to score the most impressive win of the night at Happy Valley and seal a race-to-race double. Hayes had scored in the second with Top Winner, a pick-up ride for Basil Marcus after Shane Dye was injured at Tuesday's trials, and followed with Cyber Gulch, a triumph for both horse and rider. It was Dunn's first Hong Kong winner and his first return to the scene of the accident that saw him stretchered off the racetrack and out of Hong Kong racing last March. The broken vertebra he took from the Happy Valley fall kept him out of the saddle for two months before he returned to riding in his native Adelaide, and he won the championship there despite the setback. 'I am just so happy to have ridden a winner here,' an excited Dunn said last night. 'When I got the licence to come back, people at home were saying that Hong Kong owed me something after the fall, but that wasn't how I saw it. I thought I owed Hong Kong racing something - to see that I could ride here and now I hope this will open a few more doors for me. Step one was to ride a winner, step two is to ride a few more and then we can work on step three which is to do well enough to extend my three-month licence.' Dunn said the four-year-old Cyber Gulch was always going to be tough to beat in running. 'He was travelling so easily down the back, I had to sit up so I didn't come into the race too soon,' he said. Cyber Gulch was the only winner all night to come from well off the pace and score, looping the field on rounding the turn then storming over Faithful Assurance to win running away. 'I really thought he would need 2,000 metres to show his best but he was just too good,' Hayes said. 'It's great for Dwayne and great for the horse, because he broke a sesamoid and he has come back so well.' Cyber Gulch had not started since February and last night's win was his first, but it will not be his last. 'He was a colt before and while he was out with the injury we had him gelded,' Hayes explained. 'He was just far too big as a colt but as a gelding, he is a lot easier to train. As you can see, his weight is down 60 pounds from what he was racing at last February.' Hayes and Marcus were a deadly combination during the trainer's early Hong Kong seasons and Marcus was Hayes' obvious choice when Dye was injured at Tuesday's trials. Dye received five stitches to a gash above his left eye after a horse reared up and struck him, and elected not to ride at last night's meeting to have himself fully fit for Saturday at Sha Tin. 'Naturally I feel a bit sorry for Shane but I was lucky enough to pick up the ride and I'm delighted to have won,' Marcus said. 'It makes me feel like I'm part of the Hong Kong scene again which is very exciting.' Top Winner's wide draw was a concern for the trainer before racing but with Heavenly Wind coming across to sit outside him in the run to the bend, he gave no trouble on the turns. 'David said to me before the race that he had had trouble with the turns before but he was no problem,' Marcus said. 'You know he is only a young horse and sometimes they just take a little experience to get used to the tight turns. David told me before the race he thought the horse had matured and I'd say that's right.' Peter Chapple-Hyam opened his account for the season, too, with Capital Star (Steven King) winning the opening event, leading throughout. 'Nice to get off the mark and it didn't surprise me that he won first-up, because he takes no work at all to have him fit,' the trainer said. 'If the handicapper doesn't go crazy he could win another one but he's fairly limited - he's won all his prizemoney in Class Four - and if he has to run in Class Three he will struggle.' Meanwhile, Ricky Yiu Poon-fie said Me And You, winner of only his second race in last night's second event, was only just maturing and was ready for his best season. 'It has taken him a long time to really strengthen up and mature and race like a complete horse tonight. He is a five-year-old now and now we will see the best of him,' Yiu said. In other news last night, Kingston Treasure was paraded before the crowd prior to the opening race and passed ready to resume his career at Sha Tin on Saturday. Kingston Treasure was a controversial late scratching at that track last Sunday prior to the HK SAR Chief Executive's Cup after rearing, slipping and rolling in the parade yard. Turnover was again down at last night's meeting. Last year, the meeting held $727 million in betting but was down to $676 million last night. With the poor weather, attendance was down from over 26,000 to 19,000.
