Top South African rider Anthony Delpech may miss the Mercedes-Benz Hong Kong Derby mount on leading fancy Vengeance Of Rain after being suspended at Happy Valley last night on an evening literally of ups and downs for some riders. Delpech pleaded guilty and copped a two-day ban and an $80,000 fine for his winning ride on Grand Commands in the seventh, but the real penalty will be missing his Derby appointment at Sha Tin on Sunday week. The David Ferraris-trained Vengeance Of Rain looks a frontline contender for the group one race and, barring an appeal, is now up for grabs. Delpech's crime was causing interference to Sharki (Douglas Whyte) as Grand Commands crossed over sharply on the first turn, with Win Again (Olivier Doleuze) also affected in the incident. Seeing his life momentarily flash before his eyes in a race incident for Whyte at that stage, however, had become commonplace after he and Seb Sanders tumbled spectacularly in the final stages of the first race. Three simultaneous shifts of ground by runners inside the final 200 metres saw Sanders's mount Affirmative Action clip heels and come down, taking Well Express (Whyte) down from behind in doing so. Both men walked away without medical assistance, bouncing back later in the card to ride winners. Sanders produced a gem of a ride to land the last on Healthy Wealthy but for Whyte the roller-coaster was an even more appropriate description. Ninety minutes after the fall, he led throughout to win narrowly on David Hayes-trained Salut Beaute in the Hyderabad Handicap (1,200m) but not long after found himself in the Sharki incident as that three-year-old failed as favourite after floundering in the soft ground, which had been opened up by continuing rain. In the last race, punters pinned their faith to him on John Moore's Derby hopeful Best Gift, but he, too, may now miss the race after the best he could manage was fifth, charging home late in the sloppy conditions. Moore and connections of Best Gift will now have to wait until this afternoon's announcement of the Derby field to see if Jockey Club officials elevate Best Gift into the field, taking some account of the conditions last night. Manfred Man Ka-leung continued a good run to take the training honours with a double as Wisdom Express (Craig Williams) finally broke his maiden status and China World (Olivier Doleuze) squeaked home for his fourth success. Williams picked up a lucky late ride to win on first reserve Wisdom Express after his original mount, Smiley Win, was scratched, and it gave the jockey his third opening-race win at Happy Valley meetings in recent weeks. 'He was lucky to get a run and fortunately the higher weighted horses were mostly drawn wide,' smiled Man. 'Although it is the horse's first win, I think he may have won sooner this season if he had not bled on the training track in August. As for China World, he likes the softer ground but was also suited by leading tonight.' Paul O'Sullivan added one more to his tally when Easy Game (Shane Dye) arrived in the second contest and he had the jockey to thank for advice. 'Last week he ran in that class four when they went terribly slow and he never got into it,' the trainer said. 'Shane got off him and said if I wanted to win a race with him I should back him up this week. Well, I'm into winning races so we did.' And Alex Yu Kin-shing missed an urgently needed winner when his regular ride Cenamira (Eddie Lai Wai-ming) broke through in the third. 'We could have run the horse in class five with a bigger weight but I preferred him to have a light weight and unfortunately Alex couldn't make the 113 pounds so I had to use Eddie,' said trainer Alex Wong Yu-on.
