In what was arguably the marquee clash in the Davis Cup Quarter-finals this weekend, Spain stunned USA 3-1 in the heart of Texas to book a spot in the last four against France. Spain had pulled off a double shock on Friday winning both singles encounters on the hard courts in Austin, Texas, which were widely anticipated to favour the home side. The Bryan twins gave the US an expected lifeline winning Saturday's doubles encounter to set up an exciting finale on Sunday.

The stage was set for world no.6 David Ferrer and world no.8 Mardy Fish to do battle in the first of the reverse singles, with the in-form American a slight favourite in front of the home fans on his preferred surface. The pair produced a 251 minute marathon encounter with the Spaniard prevailing 7-5, 7-6(3), 5-7, 7-6(5) to put his team 3-1 ahead. The two sides decided to call off the dead final rubber, leaving the fans slightly disappointed, though most would argue that they got their monies worth in the previous match.

The Canadian Davis Cup team completed their impressive comeback against Ecuador at the Davis Cup by BNP Paribas Americas Zone Group I second round tie on Sunday, after winning both reverse singles matches and completely erasing the 2-0 deficit they faced after Friday’s opening matches. Vasek Pospisil started the day with a decisive 6-3, 6-4, 7-5 win over Julio-Cesar Campozano which allowed Philip Bester to go out and capture the deciding rubber against Ivan Endara 6-2, 7-6(4), 6-4. The team now advances to the World Group play-offs for the first time since 2005.

After cutting Ecuador’s lead to 2-1 with the doubles victory on Saturday, Canada still needed to win both matches on Sunday to clinch the tie. Pospisil delivered a clutch performance in a battle of the No. 1 players  to keep Canada’s hopes alive and send the tie into a decisive fifth rubber. Pospisil, ranked No. 191 on the ATP World Tour, broke once in the opening set, twice in the second and the last time at 5-5 in the third frame to secure a straight sets win. The 21-year-old Canadian was poised and solid from everywhere on the court en route to the first Davis Cup singles triumph of his career after winning the doubles rubber on Saturday alongside Daniel Nestor.

Janko Tipsarevic helped defending champions Serbia book their place in the semi-finals of the Davis Cup with a routine straight sets win against Sweden’s Michael Ryderstedt in the first of the reverse singles rubbers on Sunday. Tipsarevic, who had gotten a free pass in the first singles on Friday when opponent Ervin Eleskovic retired after just 1 set, was only really tested in a tight second set, coasting to a comfortable 6-2, 7-5, 6-3 win.

A double break had given Tipsarevic the first set with consumate ease, this after he had conceded just 4 points on serve in 4 games. The players traded breaks early in the second before the Serb broke decisively in the 11th game. He served out the set in the following game.

Lleyton Hewitt had to dig deep to snuff out a valiant Chinese comeback in Beijing this afternoon and steer Australia into the Davis Cup by BNP Paribas World Group Playoff in September. Hewitt dropped just three games in taking the first two sets before Zhang Ze staged a remarkable comeback, roaring back into life and bringing a noisy 2000 plus crowd at the indoor Beijing International Tennis Centre with him. But Australia's most successful Davis Cup player managed to serve strongly and win the big points to finally close out an absorbing contest 6-2 6-1 4-6 7-6(2).

Hewitt was subbed into the singles for Marinko Matosevic this morning and his victory gave the Australians an unbeatable 3-1 advantage in their Asia Oceania Zone Group one second round tie with both teams opting not to play the fifth match. Hewitt's Davis Cup record now stands at 46-12, the greatest in Australian tennis history and incredibly, he has only ever lost one match on hard court in 31 ties over 13 years.
