Favourites flop in Longchamp mud French Classic hopefuls were out in force at a rain-sodden Longchamp this afternoon, but all three trials fell to outsiders.Okawango, the top-rated French juvenile in the international classifications last year, was the first hot favourite to be floored in the Group Three Prix de Fontainebleau.The race, a leading trial for the Poule d`Essai des Poulains, was won by Denon, owned by the Niarchos family and trained in Chantilly by Englishman Jonathan Pease.After her Grand Criterium victor Okawango had trailed in four-and-a-half lengths third, trainer Criquette Head-Maarek shrugged: 'The ground was atrocious, his programme stays the same.'Next up was the Prix du Jockey-Club trial, the Group Two Prix Greffulhe.Last year`s Criterium de Saint-Cloud winner, Sagacity, trained by Andre Fabre, was sent off the odds-on favourite.But Olivier Peslier`s mount never managed to strike a proper blow, coming in some 10 lengths back in fourth behind all-the-way winner Maille Pistol.Maille Pistol, bought with a jumping career in mind by his owner, trotting trainer Michel Roussel, was the most impressive of all the afternoon`s winners, making light of the gruelling ground to beat Nolt by half a dozen lengths.The son of Pistolet Bleu now has the Prix du Jockey-Club high on his agenda.Trainer Jean-Claude Rouget said: 'Soft ground is a big plus but this horse has a good engine too.'Finally it was the turn of the fillies with the Prix Marcel Boussac heroine, Amonita, the star attraction in the Group Three Prix de la Grotte.Pascal Bary`s filly acquitted herself well but was beaten two lengths into second by another all-the-way winner Quarter Note, trained by Alex Pantall for Sheikh Mohammed.She was beautifully ridden by Yutaka Take and is on target for the Poule d`Essai des Pouliches, where she will once again meet the runner-up.
