SECOND-season trainer Tony P. H. Chan stole the show at Happy Valley last night with a 250-1 treble. Any treble is a welcome one but last night's was particularly timely for the former champion jockey who scored with Winsome Fellow in the second, The First Million in the fourth and Super Win Boo in the sixth. He hadn't opened his account for the season until Bumper Star won at the Sha Tin meeting before last and the pressure was beginning to mount. Hong Kong's racing public are notoriously fickle and a few horses had already begun to move from Chan's yard. It doesn't take much for a trickle to become a torrent but last night's treble will have done more than put a finger in the dam. Chan's success also illustrated the complicated local versus expatriate debate. Much of the early-season news was dominated by local riders complaining they were not getting enough opportunities. The result was an extension to the local riders' scheme. But here we had Chan turning to expatriates - Eric Legrix and Darren Gauci - to replace local riders on both Winsome Fellow and The First Million. You can't argue with the results they produced and this place is all about results. Legrix conjured a perfect rails run through for veteran stayer Winsome Fellow to collar Rock 'N Reel close home in the second. Legrix said: ''The plan was to stick to the rails and that really helped. As we turned for home I was able to make up a couple of lengths and it made all the difference at the finish.'' The First Million was always travelling well for Gauci though the former Melbourne champion had to be at his most vigorous to hold off My Prince and Cruise Missile. Chan's treble was completed in facile fashion when Super Win Boo made all under a typical Danny Lee ride from the front. The eye-catching run in this race came from Ivan Allan's Applause who attracted plenty of money in both the win and quinella pools, despite being ridden by the unfashionable Frankie Lor who usually adds a good few points to a horse's starting price. Applause was desperately unlucky in the run as he was travelling strongly and poised to challenge Super Win Boo when meeting considerable interference in scrimmaging with Outsider II coming off the apex of the top bend. Kinane had better luck in the last when David Oughton's much-improved sprinter Classabove came with a determined run to catch the pace-setting Morning Patrol and All-Winners. Classabove has now won seven of his 13 starts for Oughton though he could now be in the grip of the handicapper. ''You can't ask for much more than what this horse gave me tonight,'' said Kinane. Shaka Zulu stayed on promisingly to snatch third from Morning Patrol. The opening race produced one of those results which illustrated that some horses are a revelation in their races compared to their work. It was impossible to have first-season Irish import, Chater Sovereign, on anything he'd done at the track leading into the race - especially a couple of lacklustre efforts in his trials. The members of the popular Hong Kong Cricket Club syndicate were prepared for the worst yet they came away with a winner to add to Chater Star's success for the same owners a couple of meetings back. Parkview Fame, the heavily-backed 2-1 favourite, could never get to the front and was beaten before they cornered for home. In contrast, champion jockey Basil Marcus found the perfect rails run on the David Hill-trained Chater Sovereign to come rattling home and win by a neck from The Great Nature with Global King third and the rest well beaten off. The way Chater Sovereign hit the line in this 975-metre dash he could improve again for a step up to 1,235 metres. He seemed to relish the Valley turns, sticking limpet-like to the rails. The win took Marcus to 15 winners for the season and put him level with Tony Cruz at the head of the standings. The fifth saw a much-improved effort from Wong Tang-ping's Mount Sapphire who made light of his opposition to score by four and a quarter and six lengths from Keep Winning and Determinater in a fast time for the Class Four 1,800-metre trip. Mount Sapphire has strengthened up from last season and will be very hard to beat next time out - but then he is likely to be priced accordingly.
