One of Hong Kong racing's best-loved racehorses and greatest money winners, the eight-year-old Oriental Express, was officially retired yesterday. 'He would be already more than 60 if he were a human,' said his owner, Larry Yung Chi-kin. 'I think he has earned his retirement to a green paddock.' The winner of seven races and more than $29 million in prizemoney, Oriental Express bowed out quietly but gracefully when 13th to Stay Gold in last Sunday's Hong Kong Vase. The grey, often described by trainer Ivan Allan as his favourite horse, raced in the highest class throughout his Hong Kong career, winning the Hong Kong Derby, two Champions and Chater Cups, the Chairman's Sprint Prize and QEII Cup, and was also runner-up in the Group One international mile race in Tokyo, the Yasuda Kinen. Another notable retirement yesterday was that of Lucky Win, the former Singapore-based Trillion Win. Lucky Win, who came in as a 105-plus replacement for Daliapour when he was returned to Britain, has failed to perform at all in two starts for Peter Ho.
