Davis Cup: US wins doubles to stay alive in quarterfinal

Australia advanced to the semi-finals of the Davis Cup after Nick Kyrgios rallied to beat Sam Querrey in straight sets and secure victory over the United States.

After a similar lull in the third set, he fought back from 4-1 down to close the match and the quarter-final 7-6 (7-4), 6-3, 6-4.

Australia, who lost to the U.S. in the first round previous year, will now turn their attention to Sunday's reverse singles as they bid to secure a place in the last four, with Kyrgios facing Sock before Thompson takes on John Isner.

David Goffin inspired Belgium to victory over Italy in Charlerloi on Sunday by beating Paolo Lorenzi 6-3 6-3 6-2 to wrap up an unassaiable 3-1 lead before Alessandro Giannessi saw off Joris De Loo in a dead rubber.

The 24-year-old American has already won two ATP titles this year and beat Grigor Dimitrov, the Brisbane International victor and Australian Open semi-finalist, two weeks ago.

World No.79 Thompson won 6-3 3-6 7-6 (7-4) 6-4 in a tense battle with an out-of-sorts Sock at Pat Rafter Arena.

"He's our leader and we're going to back him to go out there and play well".

Australia have not won the Davis Cup since they bagged their 28th crown in 2003.

Nick Kyrgios anchored Australia's win with victories in both his singles matches.

In the decisive reverse singles on Sunday, Sock will face Kyrgios and Isner takes on Thompson.

"I don't really get too nervous, I don't get wound up too badly".

"I feel like I've had some decent results rather than just the last couple of months", he said.

The International Tennis Federation will consider at its annual general meeting in August whether ties from next year will be reduced to best-of-three matches instead of five, and be played over two days instead of three.

"I knew that I hit a bit of a flat patch at the start of the third set but Lleyton told me to compete for every point and it's easy to get up out here", said Kyrgios.

In ominous form during last month's United States hard-court swing, Kyrgios blasted 20 aces to Isner's 15, largely defusing the towering American's serve to close out a slow-burning singles rubber in 2 hours, 24 minutes. "Playing for your country, there's no bigger honor in tennis".

Pouille, the world number 17 and his team's top singles player in the absence of Jo-Wilfried Tsonga and Gael Monfils, swept the breaker before dominating the decider.
