U.S. Sports Desk, Apr 8 (EFE).- World No. 1 Novak Djokovic defeated Sam Querrey in singles, helping Serbia clinch a 3-1 win over the United States in the quarterfinals of the World Group.
Djokovic's 7-5, 6-7 (4-7), 6-1, 6-0 win over Querrey gave Serbia the third point in the weekend's tie and helped it advance to the semifinals.
Djokovic and Querrey battled for two hours and 35 minutes on the hard court at the Taco Bell Arena in Boise, Idaho.
Serbia surprised Davis Cup fans right from the start of the tie, with the duo of Nenad Zimonjic and Illija Bozoljac defeating brothers Bob and Mike Bryan in doubles.
Serbia managed to beat the United States for the second time in two meetings in Davis Cup action. The Balkan nation first beat the U.S. team in Belgrade in 2010.
Djokovic gave Serbia the first point of the tie when he defeated John Isner in the first singles match, while Querrey, the world No. 20, beat Viktor Troicki.
Serbia, which is playing in the Davis Cup semis for the third time in four years, will take on Canada, which beat Italy 3-1, next.
The Davis Cup, tennis' premier international team competition, is played throughout the year, with the finals usually scheduled for early December.
