Roger Federer suffered defeat for the second day in succession as United States completed a surprisingly comfortable victory over Switzerland in the Davis Cup World Group first round in Fribourg on Saturday.

It was payback time for Fish who suffered two heartbreaking defeats in marathon matches in last year's quarter-finals against Spain's Feliciano Lopez and David Ferrer.

Federer has never won the Davis Cup and will have to wait at least another year to fill in one of the few blanks on his CV after a humbling couple of days in front of his home fans.

Holders Spain joined the Americans in the quarter-finals as they moved 3-0 ahead against Kazakhstan in Oviedo to give new captain Alex Corretja a pleasing start in the absence of Ferrer and Rafa Nadal.

Last year's runners-up Argentina and Czech Republic also moved smoothly through with a day to spare against Germany and Italy respectively.

Japan have an uphill battle in their first World Group tie for 26 years, 2-1 down at home to Croatia.

Nikolay Davydenko and Mikhail Youzhny kept Russia alive in their tie in Austria with victory in Saturday's doubles meaning the visitors now trail 2-1.
