Champ comes through unscathed after inquiry into feature Champion jockey Douglas Whyte continued on his merry way with a double at Happy Valley last night, including the featured American Club Challenge Cup over 1,000 metres on one of his old favourites but narrowly avoided suspension along the way. Having his first run for trainer Manfred Man Ka-leung, Jolly Gains appeared to cut off the second favourite Our Jet going around the first turn but, after a protracted inquiry, stewards eventually found the Durban Demon not to be at fault. 'I guess it was unfortunate in this case that you had the favourite and second favourite beside each other in the race and one suffered some interference, but we could not attribute that to Whyte's riding,' said chief steward Jamie Stier. 'His mount was inside Paobridge's heels and there was nothing Whyte could do.' Whyte has now ridden Jolly Gains 10 times for four wins and four seconds and the gelding kept his brilliant fresh record intact. Jolly Gains has never missed the first two placings first-up from a break. Whyte also won the opener on We're Buddies for Peter Ho, but his legion of fans were not so fortunate after Sunrise Rainbow was well beaten and quirky Sixty Seconds (Jacky Tong Chi-kit) upset favourite punters in the sixth contest. Sixty Seconds arrived on the line to win at almost 50-1 and kept intact his unusual record in only having won for apprentice riders, two of them for Tong. 'I think the kids let him run a bit so he is genuine for them while the stronger senior riders tend to want to stand over him a bit and he resents it,' said trainer David Oughton. 'I suppose he was probably a bit over the odds tonight because he usually pulls out a run when he's fresh but, having said that, he can still be a bit unpredictable.' Australian rider Brett Prebble struck in consecutive races early in the night, winning on Euphoric Kid for David Hall and then producing a carbon copy of his winning ride from the week before on Caspar Fownes-trained Mr President. 'All credit to Brett, who really seems on his way in Hong Kong racing now, but I was a little surprised how easily he got across from the outside after winning like that last time,' said Fownes. 'Once he crossed - well, as we said last week, the horse is very fit and was going to be tough to run down. He's done well but might find it harder in Class Four next time.' South African Anthony Delpech also hollered his excitement at a winning double to end the card after saluting on Fortune Life, the 300th winner in Hong Kong for Peter Ng Bik-kuen, and then on rejuvenated Arabian Wager. Gary Ng Ting-keung-trained Arabian Wager had looked highly promising in displays of sustained speed last season before his form tapered after January. With Delpech straight on to the back of tearaway leader Down For The Count, Arabian Wager was eventually back to the winner's list in the last after giving his backers a little concern when he was hard ridden before the turn in the 1,000-metre event. 'The horse has some speed but this is not his real distance even though he has won three races over it,' said Ng, who completed a double after winning with Resourceful Prince (Olivier Doleuze). 'This was not a strong Class Three and he was struggling to pick up the leader on the turn. Arabian Wager is actually bred to be a miler. 'He is probably still a bit keen for that distance just yet. But as he matures and settles down, I think he will be more comfortable at a mile and possibly even further,' Ng added. English rider Brett Doyle incurred the stewards' wrath after his ride in race three (Tori Top) caused interference 100 metres after the start. Doyle was handed a lighter penalty than Glyn Schofield last weekend, copping two days' suspension and a $15,000 fine under the new policy. Stier said the stewards' panel took account of Doyle being new to Hong Kong racing - even though he has ridden almost 100 winners here and three more than Schofield.
