Thompson, Kyrgios give Australia 2-0 lead over US in Davis Cup

Friday's second singles match pitted two of tennis' most dominant servers, the 16th-ranked Kyrgios and 23rd-ranked American John Isner.

The US originally named Sam Querrey and Steve Johnson for Saturday's doubles match against Australians John Peers and Sam Groth, but teams can make changes in the morning under Cup rules.

While he played better after the first set yesterday, he looked both physically and mentally out of the contest against Thompson and so Jim Courrier has brought in Querrey. "I got two big wins and it's hard not to like".

Courier said his team would rally around Sock and noted that his USA team had lost to Croatia past year from two matches up after the first day.

Kyrgios is due to face Sock in Sunday's opening reverse singles rubber, although Hewitt is anticipating another curve ball from the U.S. after the world number 15 was a late replacement for Sam Querrey in the doubles.

The American number one looked the more unsafe in the third but Thompson held on to force a tiebreak, gaining a vital break before taking the set when Sock double-faulted.

Belgium led their home tie against Italy 2-1 and if they advance, their semi-final against Australia in September would be in Belgium.

The win marks just the second time Australia have made it to the semi-finals in the last 11 years.

He closed it out, coming back from 2-5 down in the third set tie-break to win 7-5, 7-6 (5), 7-6 (5).

Lacking his opponent's court speed, Isner swung for the fences and scrapped to within two points of forcing another set, but two fierce returns off the Australian's racket stole the momentum and set up Kyrgios for his match-winning 20th ace.

"It's just me knuckling down for every point".

AUSTRALIA'S Davis Cup banker Nick Kyrgios promised he will "compete for every point" in future but gave notice he will remain prone to swearing and racquet throwing.

The Americans hit three winners in Peers's service game when they gained the vital break in the fifth set at 2-2. All the guys start playing better when Nick's around, which is just great.

Following the win, Kyrgios said: "That was a lot of fun".

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.
