The United States Davis Cup team round win against Switzerland on Saturday when the set victory over the Swiss duo of Roger Federer and Stanislas Wawrinka.

Bryan and Fish claimed a 4-6, 6-3, 6-3, 6-3 win to give the Americans an insurmountable 3-0 lead in the best-of-five tie. The U.S. will advance to the quarterfinals in April against the winner between France and Canada.

Switzerland entered this weekend's tie with Federer anchoring its squad at home on clay. However, the 16-time Grand Slam champion was on the losing end twice in less than 24 hours.

Fish gave the Americans the first point on Friday, gutting out a 6-2, 4-6, 4-6, 6-1, 9-7 win over Wawrinka, before John Isner did the unthinkable with one of the greatest upsets in Davis Cup history. The man best known for playing the longest Grand Slam match two years ago at Wimbledon pulled off a 4-6, 6-3, 7-6 (7-4), 6-2 victory over Federer in the second singles match on Friday to give the U.S. a 2-0 edge heading into Saturday's doubles action.
