FRIBOURG, Switzerland -- The United States swept favored Switzerland out of the Davis Cup on Saturday when Mardy Fish and Mike Bryan beat Roger Federer and Stanislas Wawrinka 4-6, 6-3, 6-3, 6-3.
Teaming for only the second time, Fish and Bryan comfortably handled the 2008 Olympics doubles champions in front of an occasionally hostile Swiss crowd of 7,000.
The Americans were kept under control for a set and a half, then seized every opportunity to exploit errors on Wawrinka's service. The crowd got angry when Bryan hit both Federer and Wawrinka with volleys at close range later in the match.
Fish and Bryan picked up the momentum of Friday's thrilling wins by captain Jim Courier's team. In the singles, John Isner stunned Federer in four sets and Fish outlasted Wawrinka in five.
Fish partnered with doubles specialist Bryan because his regular partner, twin brother Bob, was unavailable because of the birth of his daughter last week.
Mike Bryan extended his impressive record in Davis Cup doubles to 20-2, and is unbeaten in 11 away matches.
In a match of few break point chances, the Swiss took their opportunity off Fish's serve in the opening game when Wawrinka struck a winner.
Federer served for the set, but the first chance was lost when Bryan's forehand looped off the net cord as a winner over Wawrinka. That stroke of luck brought boos from some fans -- a sign of tension in the sold-out arena after Friday's surprising home defeats.
Wawrinka's angled volley winner created a second chance and Fish's backhand went long.
The U.S. broke through in the sixth game of the second set when Wawrinka twice double-faulted and Fish hit a rare crosscourt winner from the baseline.
The Americans seized on Wawrinka errors in the third set. The Swiss player hit back-to-back wayward volleys to drop serve.
Bryan angered the home fans in the next game when he made Federer yelp with pain with a forehand volley that struck his leg.
On Federer's serve, the U.S. held two set points and Bryan's volley down the middle split the Swiss pair. Bryan's double-fist pump celebration drew more whistles from Swiss fans.
Bryan became the villain again when he struck Wawrinka in the midriff with a volley in the opening game of the fourth set. Bryan's rapid apologies each time failed to quell Swiss fans' frustration.
Bryan repeated his victory dance when breaking Wawrinka to lead 3-1 in the fourth, firing a forehand winner into the open court after Federer volleyed back another net cord that favored the Americans.
The match ended on another Wawrinka error, his service return sailing long.
