Christophe Soumillon stole the show at Sha Tin on Saturday when turning in a great array rides to land five successes but the performance of Ernest Chan Kwok-hung in landing Gold Digger a winner was a huge step forward for the young apprentice. Chan was only having his 65th Hong Kong ride but showed he had made great progress in a short period of time to coax the best out of the Peter Ng Bik-kuen-trained gelding. After bouncing the five-year-old straight to the lead, Chan was unperturbed when champion jockey Douglas Whyte made a mid-race move on the favourite Winning Smile to dash around the field and look like pressing for the front. Chan kept the inside running without pressuring for the premier position - a trick usually seen from more experienced riders - before railling through on the home turn, gaining the upper hand and kicking strongly to defeat the unlucky Made In Hongkong. It was Chan's third winner, and all have come on the all-weather track, but on that display he is likely to gain more opportunities as the season progresses and it shouldn't be long before the tally increases. Made In Hongkong is only a limited conveyance but Paul O'Sullivan has the six-year-old going great guns and mark him down as a coming winner. He looked unlucky not to finish closer after being held up coming to the home bend but he will make amends when he finds another all-weather race, especially over a bit more ground. Promising three-year-old Lucky Unicorn returned with an emphatic victory on the all-weather track to confirm he's a horse going places but the performance of the fifth placegetter, Happy Master, suggested that the four-year-old is finally ready to live up to his potential. Happy Master looked full of promise when he appeared on the scene with a brilliant debut victory but he has been struggling to put it all together since. However, the positive signs were back as the gelding looked desperately unlucky not to finish closer after being checked out of the barriers, settling last, and then being held up in the early stages of the straight. Despite all the problems in the run, he hit the line strongly in the concluding stages in a performance that suggested his winning turn is very near. Fashion Jewellery has been out of luck but when the John Size-trained gelding finally gets some clear galloping room, he'll bounce back to his best. He was unlucky not to beat Very Fit after having to get around the tiring Lucky Sixer and then being short on galloping room in the final stages but, rest assured, the five-year-old is going very well.
