More Juvenile Glory For O´Brien Aidan O´Brien tightened his grip on the betting for the Classics with a Group One double thanks to Horatio Nelson and Rumplestiltskin at Longchamp. Kieren Fallon went straight into the lead on Horatio Nelson in the Prix Jean-Luc Lagardere and he always looked to have matters well under control. After seeing off the challenge of Sylvester Kirk´s Opera Cape, the son of Danehill drew readily clear to score in good style by one and a half lengths from the British challenger. Horatio Nelson was cut two points to 10-1 by William Hill for the Derby, but remains a 10-1 shot for the 2000 Guineas. O´Brien said: 'We haven´t ruled out the Breeders´ Cup. He is a staying horse, but he has also got plenty of speed. 'You only need to look at his times to see that he is quick and I don´t think a mile of the Guineas would be too sharp for him.' Rumplestiltskin cemented her position at the head of the betting for the 1000 Guineas with a narrow but convincing victory in the Prix Marcel Boussac. She came from an unpromising position under Fallon from her wide draw to lead well inside the final furlong and get the better of Quiet Royal and the Clive Brittain-trained Deveron by one length and one and a half. Coral were most impressed and cut her odds for the Newmarket Classic next spring to 3-1 from 7-1, with Ladbrokes longest at 5-1. 'Kieren gave her a masterful ride,' O´Brien said. 'It looked like she wasn´t going to get any room, but he said he always hoped it would drop right for him. 'She stays a mile well and she is a possible for the Breeders´ Cup (Juvenile Fillies´).'?
