Defending titleholder Douglas Whyte threw out a warning to his rivals for next week's Cathay Pacific International Jockeys' Championship as he gave a masterclass at Happy Valley last night to take half the card. Whyte won four of the first five races and failed by a bare margin to make it a five-timer with Warm Embraces arriving just too late in the seventh race, and in his current hot form, the Durban Demon is the one they'll have to beat if he can draw some chances. 'I couldn't be happier - everything's going well. The horses I am getting on are running well and things are falling into place,' Whyte said. 'This is the time you want it all to be happening the right way, going into a Jockeys' Championship next week and the international races the Sunday after. They say you ride your luck for as long as possible and I hope my luck hasn't dried up by next week and I can pull a few decent rides in the IJC that can get me some points.' Whyte kicked off the night coaxing a first victory from John Size-trained Octagonal Canyon in the 2,200m Class Five, only Size's second winner this season in a grade where he didn't even have a runner throughout last term. 'John doesn't have many runners in Class Five and when they do run there, they usually aren't there for long and I think Octagonal Canyon is turning the corner,' Whyte said. 'Every jockey that's ridden him has always felt that he was going to do something in his races but he's been very timid at the finish. But bringing him to Happy Valley has improved him and last start he really showed some fight and determination after being headed for second. Any horse who can do that won't be in Class Five for long and he really wanted the win again tonight.' Whyte's second win came on consistent sprinter Shy Baldy, who finally broke through for trainer Francis Lui Kin-wai, before the Demon added Nordic Star for Alex Wong Yu-on and David Ferraris' recently-acquired Speedy Warrior. 'I had ridden Speedy Warrior a while ago when he was trained by Andy Leung [Ting-wah] and he seemed to me the ideal miler for the C+3 - a horse with enough dash that you could put him in the box seat here then find a kick,' Whyte said. 'David's had him going along pretty well and when he got the right run he was able to do the job. He didn't win by far but he got the win. As for Nordic Star, I won on him over 1,200m a couple of runs ago but I told Alex the only reason he won that night was because they'd gone so hard up front. I thought we'd see the best of him at the longer trip tonight and the way he won, he might be able to win one more.' Trainer Almond Lee Yee-tat confessed some surprise that Towkay Flyer was able to take the night's feature sprint, the Chinese General Chamber Of Commerce Cup, but the punting public supported him heavily and got it right. 'I was very worried about the draw,' said Lee. 'Usually on the C+3 everybody is pushing forward and trying to get forward positions but tonight there really wasn't a lot of pace for a 1,000m race here. That allowed my horse to get across and lead on the rail and that made his job a lot easier.' Alex Lai Hoi-wing brought up a double with Towkay Flyer and Lotzatow for Ricky Yiu Poon-fie, but ended the night with a two-day ban to commence after this Saturday's meeting after causing interference early in the fifth race on Royal Portrait. Rejuvenated Luminous managed to put two wins back to back for Paul O'Sullivan and Jacky Tong Chi-kit in the seventh, following up his Sha Tin win at 72-1 with another big priced success and the trainer believes the fairest thing might be retirement now. 'That's going to make it tough for him now off a rating close to Class Two,' he said. 'The only way he might win again this season is if he struck a really wet track towards season's end.'
