Injury has added to the woes of top French jockey Eric Saint-Martin, who has stood down from rides at Happy Valley tomorrow night. Saint-Martin injured ribs in a fall at the barrier trials last week and was stood down by the club doctor from his final mount, Winning Success, at Sha Tin on Sunday after complaining of pain. One of his proposed Valley mounts, Rena's Wunderbar (race one), has been scratched and Saint-Martin has been replaced on another four. His replacements are Howard Cheng Yue-tin (Fantastic Win, race two), Olivier Doleuze (Lucky Stravinsky in race three, Famous Dancer in race eight) and Gerald Mosse (Qui's Pet, race four). No rider had been notified last night for Saint-Martin's booked mount Noble Silence in seven. It promises to be a stressful week for Saint-Martin in more than a physical sense, too, with stewards adjourning an inquiry into his handling of the John Moore-trained Viva Pataca in the Sha Tin Trophy on Sunday. Jamie Stier's panel yesterday gave notification that the inquiry would be resumed at Happy Valley inquiry room on Thursday at 9.30am. Meanwhile, it was announced on Sunday that the Hong Kong Sprint would be the new international target for Sunny Sing, the Sha Tin Sprint Trophy winner for the Moore-Saint-Martin combination on October 7. Sunny Sing had originally been aimed at the Hong Kong Mile but Moore has decided to come back to the shorter race and has therefore scrapped plans to run the gelding in the International Mile Trial next start.
