London: Argentina cruised into the semi-finals of the Davis Cup and looked poised for a clash with defending champions Serbia, who moved into a 2-0 first-day lead away to Sweden on Friday.
France were also well placed going into yesterday's doubles after Richard Gasquet clawed back a two-set deficit against Germany's Florian Mayer in Stuttgart as last year's runners-up also won both opening singles.
Spain, despite missing deposed world number one Rafa Nadal, took a commanding 2-0 lead over hosts the United States in Austin, Texas and elsewhere there were rare Davis Cup outings for Roger Federer and Andy Murray in lower-tier ties.
Federer, the 16-times grand slam champion, returned to the competition after a near two-year absence to help Switzerland take a 2-0 lead over Portugal in a European Zone tie with an error-strewn four-set win against Rui Machado in Berne.
Murray made up for his recent Wimbledon semi-finals defeat in brutal fashion, thrashing Luxembourg's hapless Laurent Bram 6-0 6-0 6-0 for a rare "triple bagel" to level the Euro/Africa Zone 2 second-round tie at one apiece in Scotland.
Serious action
While Federer and Murray went about their business, the serious action was taking place in the World Group, although Serbia's clash with Sweden was also something of a mismatch.
Even with newly-crowned Wimbledon champion and world number one Novak Djokovic pulling out of the singles with a knee niggle, Serbia made short work of the lowly-ranked Swedes who are without their powerhouse world number five Robin Soderling.
Viktor Troicki beat world number 297 Michael Ryderstedt 6-3 6-1 6-7 7-5 before Janko Tipsarevic saw off Ervin Eleskovic in quick time when his opponent retired hurt with a knee injury trailing 6-2 1-0.
"First of all I am very happy I brought the point to my country," said Tipsarevic. "But I am feeling really bad for Ervin and I couldn't imagine this day would finish this way."
Victory for Tipsarevic and Nenad Zimonjic yesterday against the decent Swedish doubles duo of Robert Lindstedt and Simon Aspelin will put the Serbians through to a mouth-watering home tie with Argentina in September.
Argentina began Friday already 2-0 ahead against Kazakhstan after their tie in Buenos Aires started a day earlier because of municipal elections today.
Decisive lead
The south Americans took a decisive lead when Juan Ignacio Chela and Eduardo Schwank beat Evgeny Korolev and Yuriy Schukin in straight sets.
Argentina, for whom Juan Martin del Potro returned to action, did not drop a set in the three rubbers.
"At the end of the day everything was easier than expected," Argentina captain Tito Vazquez said after Argentina reached their seventh semi-final in 10 years.
