A BETTING plunge on debutant Super Molly handed crack apprentice Howard Y.T. Cheng the opening leg of a tidy race-to-race double at the city track yesterday. Cheng was coolness personified astride the David Hayes-trained three-year-old who was plundered in the final moments of betting to jump at 8-1 after opening at 18-1, in from 45-1 overnight. He then produced a fighting display aboard Jewel Box for local mentor Ricky P.F. Yiu to round out a memorable day for the leading five-pound claimer, who now has 30 career wins to his name and leapfrogged South African ace Felix Coetzee to seventh on the jockeys' table. Cheng's performance on Super Molly - where he stalked just off the speed and overcame greenness and some crowding at a crucial stage inside the furlong - goes straight to the top of the list of candidates for the Apprentice of the Month award. This was a betting coup of the good old-fashioned variety and although the son of Snippets was hardly shown the whip, there were definitely some worrying moments for supporters at the sharp end of the 1,200-metre Class Three dash. Super Molly, another quality recruit fresh off the Lindsay Park production line, beat the game Delightful Special and Douglas Whyte by a neck. Corey Brown held on for third atop Brilliant Attorney. Cheng showed admirable patience with Jewel Box, giving up the lead down the back before rallying powerfully in the straight to score drawing away. This was a Class Four mile contest and the Marscay four-year-old saw out every last yard of it. He had a length and a quarter to spare on the line from the fast-finishing Comfort (Shane Dye up) with Comedy and Weichong Marwing getting up for third. The Greatest was sent out a short-priced favourite under man-of-the-moment John Egan only to be starved of a run for much of the straight to finish a disappointing sixth. But for Egan that was a rare low point on a day when he added two more to his stunning tally of 12 winners. He is now tied third with South African star Weichong Marwing. Win It All obliged for the Irish sensation in the bottom-grade opening test over 1,800 metres before guiding Chuk Way to his maiden Happy Valley victory in the mile event that opened the Triple Trio. 'It's been a fantastic start to my stint, but I'm not taking anything for granted,' said Egan. 'You're only as good as your next winner and I'm going to be keeping my head down and working as hard as I can to keep them coming.' The ease of Win It All's success surprised even Egan. 'Full marks to Peter [Ng Bik-kuen] for having him in such great shape. It was one of those rides where you just thought 'this is too easy'. He had them covered a long way out.' The seven-year-old pulled 3.25 lengths clear of Great Intent with Crown Regent getting home for third. It was also a breakthrough winner of the campaign for battling local handler Ng who had had just six placings from 39 starters before yesterday's 16th meeting of the season. Elsewhere, Brown returned from suspension and promptly returned to the winner's list when steering Welldone Kid to a runaway success in the 1,800-metre fourth event. The flashy grey son of Naturalism came from last at the final bend to deliver a lancet-like dash in the straight and score by a hard-held, three-quarters of a length over Romantic Venture for Shane Dye. Tambora Star plugged on for third.
