Sainte Marine looked ready to explode from the barriers in tomorrow's inaugural Hong Kong Sprint when working at Sha Tin yesterday. The flying French filly came through a quick quarter in 22.3 seconds and is sure to lead them up in the dash down the 1,000-metre chute. She has been moving well all week and looks a typically powerful sprinting type. The Richard Hannon-trained Wallace has been working well enough to suggest he should be included in tierces in the Hong Kong Mile. Yesterday he completed an easy 800 metres under his big-race rider, Richard Hughes, and appeared to be moving stylishly. Godolphin's Mile hope, Muhtathir, was asked to work much more seriously. This strapping chestnut clocked a fast 47.8s for his 800-metre hitout and is hard to fault. Generally, it has been last year's Cup winner, Midnight Bet, who has been impressing in readiness for the Mile in company with English raider Docksider and the home challenger, former South African Derby winner Resfa. There was no knock for Silver Patriarch's work for the Vase yesterday for which the Japanese runner Rosen Kavalier has looked good. Survey General appears in great shape for the Cup.
