ROGER Federer avenged his surprise loss to Jo-Wilfried Tsonga at this year's Wimbledon by beating the Frenchman 6-4 6-3 6-3 to reach the semi-finals of the US Open.
Third-seeded Federer now faces a scintillating showdown in the last four against top seed Novak Djokovic\[Ian Winterton\] for his eighth straight U.S. Open semi-finals appearance.
Rafa Nadal had earlier advanced, then led a player revolt that pressured organisers into rearranging the schedule.
The defending champion was quick to express his displeasure, in a little over two hours, after weather delays left him facing the daunting prospect of having to win four matches in as many days to retain his title.
Andy Murray and Andy Roddick won their matches to set up ties with John Isner and Nadal respectively. Roddick later joined forces with Nadal and Murray to berate the tournament referee Wednesday when they were asked to play in light rain and let his feelings known again when the Louis Armstrong Stadium court started leaking water and staff tried in vain to dry the playing surface.
“Find us a court,” Roddick snapped. “At a certain point that has to take precedence over what people can watch.”
Meanwhile, Serena Williams progressed and faces Caroline Wozniacki after the Dane beat Germany's Andrea Petkovic 6-1 7-6 in her semi.
Australia's Sam Stosur demolished world number two Vera Zvonareva 6-3 6-3, stretching her winning streak over the Russian to eight matches, and looms as the dark horse after some impressive displays.
She and will next play unseeded German Angelique Kerber in their quarter-final.
Andy Murray and Andy Roddick won their matches to set up ties with John Isner and Nadal respectively.
Roddick showed glimpses of the form that saw him win at Flushing Meadows in 2003 as he ousted Spanish fifth seed David Ferrer 6-3 6-4 3-6 6-3 to set up a quarter-final clash with Nadal, while Isner beat Gilles Simon 7-6 3-6 7-6 7-6 to set up a showdown with Murray.
