A BIG morning at the track for Patrick Biancone yesterday as a prelude to what could well be a big afternoon at the sports for the legendary French handler today. Biancone is a great believer in working his horses on the eve of their intended races and yesterday was no exception as he put his four top chances on the quality National Panasonic card through their paces. Improving maximum claimer Sherie Kong has been entrusted with the ride on Big Mac in the third event which is reserved for local riders. Do not be put off by the fact that Biancone's champion apprentice Simon 'Hong Kong' Yim is on board stablemate, Amazing Win, in the same race. Big Mac looks the main hope for the Biancone camp in this race. Kong's big problem with her riding has been over the last 200 metres. Until the past few weeks she has appeared to lack the wit or the strength to really pick one up and get it to the line. What she has never lacked is strategy, positioning and speed of reaction through a race. She also has shown good balance and ability to get her mounts travelling. But the signs are now there that Kong is beginning to master those telling final moments. She certainly kept Niagara Falls going well when breaking through for her first win on Ladies' Day and she looked good when weaving her way through to claim second on Hammerhead on Wednesday night. Yesterday, she took Big Mac through a most pleasing 1,200-metre hitout in one minute and 22.4 seconds. Big Mac has always been a good worker but, allowing for his noted trackwork fluency, he does look to have improved from last season. Kong is able to claim 10 pounds this afternoon and that could be a telling amount in a local riders' affair. Got It Made worked strongly earlier in the week with Hong Kong Supreme and again impressed yesterday as he sauntered home in 26 seconds for his final quarter to complete an easy 1,200 metres in 1:27.3, this time under Yim. Got It Made is in a difficult fifth event, the Japan Racing Association Trophy, but on this week's trackwork showing he is worth keeping safe in the quinellas. Gallant Dragon was asked for a serious effort by senior stable jockey Eric Legrix, clocking 1:21.6 with a good last quarter in 24.1 seconds. He will start one of the favourites in the sixth. Then there is Biancone's main hope for the season ahead, Deauville, who faces a big test in today's exciting feature event, the National Panasonic Cup. He was asked to work in much the same way as Got It Made, just enjoying a pipe-opener and strolling through his last section in a comfortable 26 seconds. Biancone has not asked too much of him since his reappearance success as there is still plenty of natural improvement to come from this son of Groom Dancer who, despite a huge rise in the ratings, should still go very close to winning. The French handler then went on to take the first of two trials on the main all-weather track as Hong Kong Supreme ran out a decisive three-length winner from David Hill's Pleasant Win who made much of the running under Basil Marcus. Stephen Leung's Make Merry showed he is on his way back to peak form when taking the other trial in which the Marcus-ridden Source Of Life ran on strongly over the final 200 metres. First trial 1, HONG KONG SUPREME (E. Legrix); 2, Pleasant Win (B. Marcus); 3, Magnified (L. F. Chung).
