Unheralded Jordan Thompson stunned world number 15 Jack Sock in four sets in the opening rubber of the Davis Cup quarter-final between Australia and the U.S. in Brisbane on Friday.
The 31-year-old American world number 23 is poised to go up against the 16th-ranked 21-year-old in the singles as the traditional Davis Cup opponents go head-to-head at the Pat Rafter Arena this weekend.
The unheralded Thompson stunned world number 15 Jack Sock in four sets in the opening rubber before Kyrgios saw off the big-serving John Isner 7-5, 7-6 (7/5), 7-6 (7/5).
He clawed back from 5-2 down in the deciding tiebreaker to finally end Isner's resistance after almost two-and-a-half hours.
"Outside of the top five (Murray, Djokovic, Wawrinka, Federer and Nadal), I now think that Nick is the most likely to win a Slam". "I'm trying to knuckle down and compete for every point and that's something I haven't done in the past", he said.
Generally over best-of-five on the day the better player will win.
"I feel like I've had some decent results, not just the last couple of months".
"He's got a great serve and a really big forehand". I've never been able to be consistent.
Mental health service proposal now in priority list
It is now the second leading cause of death among people aged 15 to 29 - a statistic that should jolt us all into action. A lot of the country still views depression , and other mental health issues, through an antiquated lens.
The win sets up an intriguing final day, with tennis "bad boy" Nick Kyrgios getting the chance to win over the Australian public when he takes on Sock in the first of the reverse singles.
The host nation, which has won tennis' premier global team event 28 times, now needs just one more win for a berth in the Davis Cup semi-finals.

The oft-controversial wunderkind Kyrgios got the better of Isner, winning in straight sets, when they last faced each other at the Atlanta Open in 2016; but Isner has the advantage in the head to head, beating the firebrand Australian, ranked 16th in the world, in their two other matchups to date. What did he do well?
"He served well, made a lot of balls".
"There could be worse ways to start", Thompson said. Playing only his second Davis Cup tie, Thompson, 22, went into the match against the American number one as the huge underdog. It was unbelievable how it happened.
In the first match, Jack Sock of the United States took on the 79 ranked Jordan Thompson, and the Nebraska native struggled to find consistency on his serve throughout the match.
