Jessy springs 20-1 Nell Gwyn shock Clues for the Sagitta 1000 Guineas were thin on the ground as Lil`s Jessy emerged victorious in the Shadwell Stud Nell Gwyn Stakes at Newmarket today. The 20-1 shot was pushed clear in the final furlong by Pat Eddery to defeat Zaheemah by three parts of a length in the Group Three contest. With the winner not even entered in the 1000 Guineas, betting for the first fillies` Classic was hardly changed. Winning trainer Jeremy Noseda admitted he does not believed Lil`s Jessy is good enough to return to this course for the Guineas. 'If I thought she was good enough for that I would have entered her for the race,' he said. 'But I wouldn`t put her in the same category as Kalypso Katie and Wannabe Grand who were both second for me in Classics. 'It doesn`t look good for the horses behind her but you`ve got to be realistic about these things.' Eddery added: 'I doubt if you saw the Guineas form there.' Khulan, the favourite, faded into fourth and has now been removed from the Guineas betting by William Hill. Trainer John Dunlop said: 'I don`t think she got tired. You have to accept she has stamina limitations which we always feared.'Primo Valentino returned to form when making every yard of the running in the six-furlong NGK Spark Plugs Abernant Stakes. Strongly ridden by Richard Quinn the 9-1 chance held on to score by a length and a quarter from Fath. Primo Valentino had looked set to take high rank among sprinters after winning his last four races as a juvenile in 1999, including the Mill Reef and Middle Park Stakes. But he failed to add to that tally last term, showing his best form when a length-and-a-half fourth behind Agnes World in the Group One July Cup.The winner is owned by the 12-strong Primo Donnas Syndicate who at one stage were thinking of selling the colt as a stallion.
