It's do or die for the United States of America in the Davis Cup when doubles hits the Pat Rafter Arena after Nick Kyrgios and Jordan Thompson got Australia off to the ideal start yesterday.

Nick Kyrgios has sent Australia through to the Davis Cup semifinals, with an emphatic straight-sets win over American Sam Querrey.

Kyrgios and Jordan Thompson put Australia in the box seat when they won the opening singles on Friday.

Thompson, Australians No. 2 singles behind No. 16 Kyrgios, was a prohibitive underdog against Sock.

Isner said Kyrgios was now a more mature player than in their 2015 and 2016 matches.

The victor moves on to play the victor between Italy and Belgium.

The U.S. leads the head-to-head 26-20 and won the most recent meeting between the teams past year on grass at Kooyong in Melbourne in the first round.

A rejuvenated Sock then partnered Steve Johnson to defeat Groth and John Peers in a five set Saturday doubles thriller. "I don't know. He played a good match so deserved to win".

"Just playing within myself, not trying to go too big", Thompson said post-match.

Roared on by a partisan crowd, Kyrgios won the tiebreak 7-4 when Querrey went long with a return and 33 minutes later was two sets up after the American erred in nearly identical fashion. "I'm only human. I'm not going to change in that department", Kyrgios said.

"Maybe not the guys in the locker room who have to play against him, but for everyone else involved in the sport, it's a great thing if Nick can find his potential".

"I try and defend him and stick up for him a lot as well, but I love having him in my team".

"But [with coach] Lleyton (Hewitt) on the side, telling me to compete for every point, and obviously the crowd, it's easy to get up out here".

US Davis Cup captain Jim Courier has no doubt about Kyrgios' potential.

Peers and Groth raced out of the blocks to win the first set in just 27 minutes and they looked good value to continue their positive Davis Cup run after previous doubles wins against Czech Republic and Slovakia.

"It was a tremendous effort against a high-quality doubles team, but it's going to take a really monstrous effort from us tomorrow".
