Federer strolls into US Open quarters

NEW YORK: It was a bleak day for US tennis on Monday as for the first time in the 41-year Open era no American made it into the quarterfinals of the men''s singles.

The last to fall was giant John Isner, who was toppled by Spain''s Fernando Verdasco 4-6, 6-4, 6-4, 6-4.

Top seed and defending champion Roger Federer, meanwhile, moved a step closer to a record-equaling sixth straight title with a routine 7-5, 6-2, 6-2 win over outclassed Tommy Robredo of Spain.

In the last eight, he will play the man be beat in Paris to end his French Open jinx, Robin Soderling, who moved on when Nikolay Davydenko abandoned with a thigh strain when trailing 7-5, 3-6, 6-2.

Verdasco will go up against fourth seed Novak Djokovic of Serbia who eased past Radek Stepanek of the Czech Republic 6-1, 6-3, 6-3 in a disappointing night-time session match on the Arthur Ashe Stadium court.

Five points from a straight-set loss, Oudin kept plugging away with her perpetual-motion defense and pick-her-spots offense for a 1-6, 7-6 (2), 6-3 victory over 13th-seeded Nadia Petrova to reach the U.S. Open quarterfinals.

The woman who eliminated No. 1 Dinara Safina, Petra Kvitova of the Czech Republic, couldn''t build on that, losing in three sets to Yanina Wickmayer of Belgium, while Kateryna Bondarenko of Ukraine shut out Gisela Dulko of Argentina 6-0, 6-0.

Like Oudin and Wozniacki, Wickmayer and Bondarenko are first-time Grand Slam quarterfinalists.
