Cox pleased with Xtension prep Clive Cox is "very happy" with Xtension ahead of Saturday's bid for 2000 Guineas glory. Xtension was narrowly touched off by the Aidan O'Brien pair of Beethoven and Fencing Master in the Dewhurst, having earlier won the Vintage Stakes at Goodwood and finished second to Canford Cliffs in the Coventry. "He's wintered well, he looks well and we are happy with his preparation, we are very happy," said Cox. "You couldn't be disappointed with his Dewhurst run. He briefly hit the front and to be beaten in a three-way finish like that, a nose and a neck, I was delighted to be honest. "We trained him last year with the idea that he would progress with a little bit of luck and he always gave us that inclination. "I'm pleased to say he wintered well and I'll be very disappointed if he doesn't give a very good account of himself. "We are looking forward to seeing him over a mile, his style of racing is very laid-back and he is blessed with a good turn of foot," he told At The Races.
