Rafael Nadal into US Open third round after Nicolas Mahut retires

The defending champion, Rafael Nadal, safely progressed to the third round of the US Open after his opponent Nicolas Mahut retired at the start of the third set.Nadal had lost his only previous meeting with the Frenchman, going down at Queen's Club in 2007, but there was little chance of a repeat on Friday with the world No2 in dominant form as he built a 6-2, 6-2 lead before Mahut pulled out.Nadal, the Spaniard who beat Novak Djokovic in last year's final to win his first US Open title, will next face the Argentinian David Nalbandian.The former champion <a href="http://www.monclerjacketscoats2011.com/"><strong>cheap moncler jackets</strong></a> Juan MartÃ*n Del Potro eased into the third round of the US Open with a 6-2, 6-1, 7-5 victory over his fellow Argentinian Diego Junqueira.Del Potro is playing in the tournament for the first time since winning the title in 2009 after missing last year with a wrist injury and he is certainly someone the top seeds will want to avoid.Del Potro freely admits he is not yet back to the level than saw him beat Roger Federer in five sets in the final two years ago but he feels he is on the right track.The 22-year-old said: "I played better than my first round. I was more confident with my forehand, especially in the beginning of the match. It doesn't matter if you play good or not in the first round if you win. Now I'm in the third one, so I need to improve, I need to be more confident with my serves and forehands."The wild card Julien Benneteau is also through to the third round after a 6-4, 6-4, 6-4 win over Denis Istomin. <a href="http://www.cheapestuggs2011.com/classic-cardy-c-240.html"><strong>uggs boots sale</strong></a> The Frenchman has carried on his good form from the ATP World Tour event in Winston Salem last week, where he reached the final.John Isner, the giant American, who beat Benneteau in Winston Salem, continued <a href="http://www.monclerjacketscoats2011.com/"><strong>moncler jackets coats discount</strong></a> his good form, the 28th seed seeing off his compatriot Robby Ginepri 6-4, 6-3, 6-4 to make it seven straight wins.Donald Young, once the great teenage hope of American tennis, pulled off the best result of his career with a 7-6, 3-6, 2-6, 6-3, 7-6 victory over the 14th seed, Stanislas Wawrinka, showing that at 22 he may now be ready to live up to his potential.The 17th seed, Jürgen Melzer, was also knocked out in five sets, losing 3-6, 6-3, 1-6, 6-2, 7-6 to Russia's Igor Kunitsyn but the 12th seed, Gilles Simon, and 24th seed, Juan Ignacio Chela, are through while Luxembourg's Gilles Müller beat Ernests Gulbis.
