Andreas Suborics, who scooped the $10 million Audemars Piguet Queen Elizabeth II Cup with Silvano on his last visit to Hong Kong, will have the chance to make his mark again in December when he starts a three-month stint as a Club jockey. The German-based Austrian was one of four new riders announced yesterday, along with three-time German champion Andrasch Starke, British title-holder Kevin Darley and leading French jockey Olivier Doleuze, a fresh name on the Hong Kong scene. The quartet are scheduled to start on December 17, with their contracts due to end on Derby Day (March 17). The Licensing Committee also gave the go-ahead for Irish star Michael Kinane to return as a Club jockey, starting at the Chinese New Year meeting on February 14 and ending on Derby Day. Suborics, 30, has leapt to international prominence this year due to his tremendous run of success aboard Silvano. As well as their Hong Kong victory, the pair also landed the Singapore Cup in March and last month's Arlington Million in Chicago, and their next assignment is likely to be Australia's major weight-for-age race, the WS Cox Plate, in October. Suborics had a short stint in Hong Kong in February 1998, failing to win in 27 rides. Starke, a great rival of Suborics in Germany, had a rollercoaster first stint as a Club jockey last season. He won on seven of his 72 rides and took the International Jockeys' Challenge, but he also made history as the first Hong Kong-based jockey to test over the limit for blood alcohol levels and was given a seven-meeting suspension. Doleuze, 29, is retained by leading French trainer Criquette Head-Maarek, for whom he landed the KrisFlyer Singapore Sprint aboard Iron Mask in May. Although the former French champion apprentice will be new to Hong Kong, he has also ridden in Mauritius and Australia during the past year. Darley, 41, became British champion for the first time last year and is currently 13 winnners behind Kieren Fallon as he bids to retain the title. Darley rode in last year's International Jockeys' Challenge and, in his previous stint in Hong Kong, won on five of his 70 rides between December 1996 and February 1997. Trainer Gary Ng Ting-keung confirmed yesterday that the owners of troublesome sprinter Kingston Treasure are to appeal against the gelding's compulsory retirement following his scratching at Sha Tin on Saturday night.
