Stanislas Wawrinka outclassed eighth seed Andy Roddick 6-3 6-4 6-4 on Sunday to set up an Australian Open quarter-final with close friend and fellow Swiss Roger Federer.
"Stan" -- as Beijing Olympic gold medal partner Federer fondly calls him -- out-aced American Roddick 24-9 as he ensured a first grand slam quarter-final between two Swiss men since the sport turned professional.
Wawrinka, seeded 19th but playing tennis 16-times grand slam champion Federer would have been proud of, caught Roddick cold under the Melbourne floodlights, breaking for 5-3 in the first set with a drilled backhand pass and never looked back.
Roddick was a step slower than his unshaven opponent, who had too many ideas and executed his shots superbly.
The contest ended after two hours and 22 minutes when Roddick sliced a weary backhand into the net to leave no Americans remaining in either singles draw.
