Sock to Open Against Thompson in U.S. v Australia Davis Cup Tie

BRISBANE, Australia -- American Jack Sock and Australian Jordan Thompson will kick off the U.S. v Australia quarterfinal tie on Friday (Thursday 10 PM ET in U.S.) in Brisbane, Australia.

Ranked world No. 15, Sock will aim to lead U.S. to the semifinals in hopes of winning their 33rd championship. Sock is 5-2 in Davis Cup versus Thompson's second appearance.

In the second rubber, 23rd-ranked American John Isner will battle against 16th-ranked Nick Kyrgios, who's coming off a great run in the 'Sunshine Double.'

After going 0-2 against one of the biggest servers on tour, Kyrgios was able to win their last encounter in Atlanta last year.

"I feel confident with that match-up, comfortable playing second," said Kyrgios. "You’re obviously not going to get too many looks on his serve but if you take care of your own, you’re going to get some looks [at a second serve]. That’s really all I did in Atlanta."

Isner praised Kyrgios's good form.

"In my opinion I think he's a lot more mature now," said Isner about Kyrgios "Right now, a lot of people could argue he's playing maybe the best tennis he's ever played."

This will be a second clash in a row between the two countries, with the United States triumphing in last year's first round in Melbourne. Overall, the two countries have played 46 times, with U.S. leading the head-to-head 26-20.

United States is the most successful nation in Davis Cup history. It also holds the hold the record for consecutive wins, having won 19 ties in a row between 1968-1973. It is also the first country to claim the Davis Cup trophy in 1900.
