Douglas Whyte stole the show at Happy Valley last night with a sparkling double - but it could so easily have been a treble or even a four-timer. Whyte strengthened his grip in the jockey standings with well-executed victories on Gary Ng Ting-keung's seasoned campaigner Mission Sealed and the promising Prospero, who completed a double for trainer Alex Wong Yu-on following Core Principles' win in the opener. The double made it 36 winners for Whyte, who also came close to victory on neck runner-up Melrose Star in the third race and had another second place with Qui Vivra Verra in the opener. Whyte, who returned from suspension at Sha Tin last Friday, has come back in tremendous form, and his victory on Mission Sealed in the fourth race could not have been bettered. The South African kept his mount tight to the rail and the ground-saving ride paid off as he denied Jet Jackson, ridden by Whyte's closest rival Robbie Fradd, by a head. Trust Me was a warm favourite to be another first-time-out winner for Andy Leung Ting-wah in the 1,200-metre contest, following Conjuring's impressive debut victory last Friday, but he failed to live up to expectations with a disappointing sixth. Trust Me was given every chance by John Egan, who had the three-year-old in third on the turn, but his mount swung wide into the straight and did not find as much as anticipated in the run to the line. Whyte was equally impressive in the next race on Prospero, who came from barrier 12 to land the 1,200-metre contest in a finish of short-heads with market rivals Masterpiece and Namjong Spirit. With those three useful young prospects in the line-up, this looked a hot race on paper and so it proved on the track with Namjong Spirit and Masterpiece engaged in a battle royal in the straight after tracking the pacesetting Classic Jester. But Whyte launched a strong finish down the outside to snatch victory from Masterpiece just when Howard Cheng's mount had got the better of Namjong Spirit. Fradd, the reigning champion, now lies seven behind Whyte after moving into a clear second place in the standings with victory on Ivan Allan's Magic Win in the opener over 1,650 metres. The jockey was praised by Allan for his ride on the four-year-old grey who trailed the pacesetting Leopard before responding willingly in the straight to hold off Whyte on the late-finishing Qui Vivra Verra. Allan said: 'Robbie rode a good race because the plan was to lead, but once Robbie saw he couldn't do it, he just dropped in behind and waited.' The Class Six victory was Magic Win's second in three starts after finishing unplaced in his first six outings following his purchase unraced out of the Tattersalls Newmarket sale-ring in England. Allan said: 'He took a long time to come to hand and we will continue to do things gradually with him. He may move up to Class Four in time, but above all we won't rush him.' Australian rider Corey Brown, riding at his last meeting in his stint as a Club jockey, was given a three-meeting ban and a $20,000 fine for careless riding following his victory on Wong Yu-on's Core Principles in the opener - but it did not take the gloss off his swansong. Brown, who flies home today to take up a job with leading Sydney trainer John Hawkes, said: 'It's great to have a winner at Happy Valley after riding a double at Sha Tin in my last meeting there, and it's a fantastic way to go out. I'm not too worried about the ban because I planned to take a break when I get back home and I will still be free for my first big race on Diatribe in Melbourne on February 11.' French rider Davy Bonilla, also ending his stint as a Club jockey, was another handed a three-meeting ban for careless riding on fourth-placed Hin Yuen's Unicorn in the fifth race. The Lawrie Fownes-trained Rangeela continued his resurgence under more waiting tactics with victory in the third race. The six-year-old had been a habitual front-runner until owner Ricky Samtani suggested a switch to a hold-up approach, and it has paid dividends with two wins and a second from four starts since the change. Five horses were virtually abreast 100 metres from the line in the 1,800-metre contest, but Wendyll Woods got Rangeela home by a neck from Whyte's mount Melrose Star, with Sky Hawk half a length behind in third. Woods said: 'I'm so pleased to win this for the owner, and all credit to him for suggesting that we change tactics. Weichong Marwing won on him last time, and a change of rider also seems to have worked the oracle, so I'm delighted to have won on him.' On a night when the photo-finish equipment was kept busy, there was another close finish in the feature race, the Volunteers' Challenge Cup. Victory went to Brian Kan Ping-chee's Rainbow And Gold, who handled the step up in trip to 2,200 metres well to score by a short head under Gerald Mosse, with Lucky Sabre second and Bon La Vie three-quarters of a length back in third. Tony Cruz endured some cruel luck on the night, notably with Namjong Spirit, but he finally got on the scoreboard in the last race with Danswinner. This time the short-head verdict went against Mosse, whose mount Hornet was edged out by Cruz's gelding in the 1,650-metre contest.
