FRENCH star Gerald Mosse will be back in action in Hong Kong next month partnering top American hope Adam Smith in the $5 million International Cup. Mosse, who made a brief visit to Hong Kong late last month, is delighted to be riding again at Sha Tin on December 12 - and he is likely to have plenty of rides outside his single confirmed engagement. ''I am so very pleased to be returning to Hong Kong to ride. It was most enjoyable being back last month briefly to see a number of old friends and now I am getting the chance to ride again at Sha Tin. ''Last year I was a bit unlucky not to win the International Bowl on Helene Star so I really hope I can go one better and win the Cup on Adam Smith. I do not know a great deal about the horse but he has been prepared for Hong Kong,'' said Mosse. Adam Smith is trained by Claude Clement, related to Nicky Clement who was Patrick Biancone's assistant and now trains at Chantilly. Mosse has had real success in France and Europe since his dramatic split with Biancone at the end of last season. Fields for both International events are now virtually settled, with Australian rider Mick Dittman being confirmed as the partner for Dark Ksar, trained by David Hayes. Dittman is already down to ride Capestad in the Bowl and the Australian sprinter is considered a very live chance. Dittman, too, can expect to have a number of rides outside the two-feature races. Local racegoers will also get the chance to see a top American rider in action with the news that Gary Stevens will partner Stark South in the 1,800-metre Cup. Stevens, who won the Japan Cup two years ago on Golden Pheasant, is considered by most observers to be one of the very best American riders on turf and over distance. Unlike so many of his compatriots, he is not a speed rider but one with a good tactical brain and a thorough knowledge of how to ride stayers from behind on turf. And also making a belated return to Hong Kong is New Zealand-born Bruce Compton who was stable rider for John Moore before the partnership foundered with the late Noel Barker then taking over. Compton will ride Kiwi Bowl hope Danjiki while New Zealand champion Lance O'Sullivan will partner Lodore Lady in the Bowl and Kiwi Golfer in the Cup. French entry Marildo looks certain to stand his ground for the Cup which means the fields are complete, barring the local runners, and those from the MRA which will be announced officially next week. The Cup field with riders is: Dark Ksar (Mick Dittman); Silk Ali (Grant Cooksley); Kiwi Golfer (Lance O'Sullivan); Alflora (Mick Kinane); Marildo (Guy Guignard); Verveine (Olivier Peslier); Adam Smith (Gerald Mosse); Stark South (Gary Stevens); Narita Chikara (Take); Navajo II (Frankie Dettori). Bowl lineup: Capestad (Dittman); Danjiki (Bruce Compton); Lodore Lady (O'Sullivan); Voleris (Cash Asmussen); Swing Low (John Reid); Journalism (Corey Nakatani); Karinga Bay (Brian Rouse); Now Listen (unjockey); Dojima Muteki (Take).
