World Group Roundup

Defending champions Spain advanced to the quarter-finals of the Davis Cup with a 4-1 victory over Switzerland.

The home side took a 2-1 lead into Sunday's reverse singles and David Ferrer quickly wrapped up the tie with an easy win over Stanislas Wawrinka.

Ferrer, who also won his first singles match on Friday, triumphed 6-2 6-4 6-0 and then Spain's Nicolas Almagro put the icing on the cake in Logrono with a comfortable 6-1 6-3 victory over Marco Chiudinelli in the fifth rubber.

Their quarter-final opponents will now be France, who also beat Germany 4-1 in Toulon.

The French, who had already taken an unassailable 3-0 lead, lost the fourth rubber when Jo-Wilfried Tsonga retired during the third set against Simon Greul but they finished on a high with Julien Benneteau defeating Benjamin Becker 6-2 7-5.

Novak Djokovic survived an epic match with John Isner to give Serbia a decisive 3-1 advantage over the United States in Belgrade.

Djokovic needed four hours and 16 minutes to eventually get the better of a courageous Isner, the world number two finally sealing a 7-5 3-6 6-3 6-7(6) 6-4 victory.

Sam Querrey won the dead fifth rubber against Viktor Troicki 7-5 6-2 but the overall defeat means Patrick McEnroe's US team faces a relegation play-off later this year to maintain their record of playing in the World Group every year since 1989.

David Nalbandian's last-gasp trip to Stockholm paid dividends as he saw Argentina to victory over Sweden.

The former Wimbledon finalist only flew in on Thursday night after looking set to miss the tie with a leg injury, but teamed up with Horacio Zeballos for victory in Saturday's doubles to give the visitors a 2-1 lead.

And after Robin Soderling beat Leonardo Mayer in straight sets on Sunday to level the tie at 2-2, Nalbandian beat Andreas Vinciguerra 7-5 6-3 4-6 6-4 to seal the win.

Elsewhere, Russia completed a 3-2 victory over India, with Mikhail Youzhny claiming the decisive point in the fourth rubber courtesy of a 6-2 6-1 6-3 win over Somdev Devvarman in Moscow.

Rohan Bopanna of India won the dead fifth rubber when beating Teimuraz Gabashvili 7-6(5) 6-4.

Meanwhile Croatia wrapped up a resounding 5-0 triumph against Ecuador in Varazdin following victories in the two remaining rubbers.

Antonio Veic beat Julio-Cesar Campozano 6-4 7-6(4) before Ivan Dodig sealed the whitewash with a 6-1 6-3 win over Ivan Endara.

The Czech Republic had also booked their quarter-final spot with a day to spare against Belgium and finished up with a 4-1 victory in Bree after the two remaining two singles rubbers were shared.

Steve Darcis salvaged some pride for Belgium with a 7-6(6) 1-6 6-4 win over Jan Hajek before Lukas Dlouhy beat Christophe Rochus 1-6 7-6(3) 7-5.

Chile will head into the final day of their delayed clash with Israel in Coquimbo holding a narrow 2-1 lead after the visitors claimed a dramatic five-set victory in the doubles.

Israel's Jonathan Erlich and Andy Ram teamed up to beat Jorge Aguilar and Paul Capdeville 6-7(5) 7-6(11-9) 2-6 6-1 6-0 to ensure there's all to play on Monday.

However Chile's singles players, Fernando Gonzalez and Nicolas Massu, will be strongly fancied to clinch a home victory when they face Dudi Sela and Harel Levy respectively.
