What the Aga Khan and jockey Christophe Soumillon failed to achieve in Saturday's Epsom Derby with Visindar, they accomplished in Sunday's Prix du Jockey-Club at Chantilly as the unheralded Darsi prevailed to win the French Derby. International handicappers may be scratching their heads over the names of the first three finishers in the $1.92 million classic, as none of them had ever won anything better than an allowance race. Darsi, the three-quarter-length winner, had recently won a 1 9/16-mile race at Chantilly. Runner-up Best Name had won his maiden in a 1 1/4-mile Longchamp allowance last time, while Arras, who finished a short neck behind Best Name in third, lost for the first time following allowance scores at Saint-Cloud and Bordeaux. A Polish Precedent colt out of a mare by the Aga Khan's foundation stallion Darshaan, Darsi (7-1) was never worse than fifth throughout the 1 5/16 miles. He led at the sixteenth pole, clocking a course-record time of 2:05.80 on good ground that was riding fast all afternoon. The Irish Derby at The Curragh on July 2 is the next logical stop for Darsi. Epsom Derby: Sir Percy takes four-horse photo Jockey Martin Dwyer brought Sir Percy up the rail with a scintillating late run to win the $2.35 million Epsom Derby in a blanket four-horse finish Saturday. The race also saw the breakdown of Horatio Nelson, who was later euthanized. A son of European champion miler Mark of Esteem, the 6-1 Sir Percy just got up to defeat the 66-1 maiden Dragon Dancer by a short head, with the pacesetting Dylan Thomas another head behind in third and recent maiden winner Hala Bek - who was making just his second start - in fourth, a head behind Dylan Thomas. It was another two lengths back to the 2-1 favorite, Visindar, the previously undefeated French challenger who found little when the real running began entering the stretch. The time for the 1 1/2 miles was 2:35.23 on ground labeled good to firm. There was no doubting Sir Percy's class. He had capped an undefeated juvenile campaign with a pair of victories at seven furlongs in the Group 2 Vintage Stakes and the Group 1 Dewhurst Stakes, England's definitive 2-year-old race. In his seasonal debut on May 6 he ran second to George Washington in the 2000 Guineas in his first try at a mile. Out of a mare by the 1969 Epsom Derby winner, Blakeney, Sir Percy proved on Saturday that the European classic distance is well within his scope. The Irish Derby on July 2 looms as his next objective, where he could be joined by the fast-improving Hala Bek. The start of the Derby was delayed by 10 minutes as veterinarians checked the condition of Horatio Nelson. With his trainer, O'Brien, present, the 11-2 second choice was finally allowed to enter the gate, and jockey Kieren Fallon had Horatio Nelson in perfect position a few lengths off the lead when disaster struck at the three-sixteenths pole. As Visindar loomed up alongside, Horatio Nelson's legs gave way beneath him. He stumbled and was immediately pulled up, soon to be vanned off, having broken a front leg. * Bullish Luck hit a big triple at Tokyo on Sunday as his victory in the $1.85 million Yasuda Kinen gave him the Asian Mile Challenge title and, along with it, a $1 million bonus. Added to the Yasuda Kinen's first prize of $913,000, Hong Kong invader Bullish Luck had himself a $1,913,000 payday in the Grade 1 mile, in which he swept to victory by 2 1/2 lengths over last year's winner, Asakusa Den'en.
