BRISBANE, Australia (AP) Nick Kyrgios finished off John Isner with his 20th ace to give Australia a 2-0 lead over the United States in their Davis Cup quarterfinal on Friday.
The winners of this tie will go through to a semi-final against either France or Great Britain.
Even Hewitt thought a win might be a bridge too far but his body language on the side of the court said it all as Thompson showed a clinical side when Sock began to lose energy and errors filtered in to his key weapon, a whipping forehand.
"We saw a player who's come of age, there's no doubt about that", Woodbridge said during Channel Seven's commentary.
A win in Saturdays doubles rubber could set up a semifinal date with Italy or Belgium in September for Australia, with John Peers and Sam Groth due to take on Sam Querrey and Steve Johnson.
"In-form Sock, the highest ranked player in the tie at world number 15, will be going into the unknown all weekend as he has never previously faced Kyrgios either".
Australia are seeking revenge after losing t o the U.S. in the first round past year and would progress to the semi-finals for only the second time since 2006 if Sam Groth and John Peers can wrap things up against Steve Johnson and Sam Querrey on Saturday.
Kyrgios looked confident and untroubled throughout his encounter with Isner.
"He's one of the best servers in the world, a proven player".
"I've got a head cold right now and trying to fight through it - not feeling great".
Earlier Friday, Australia's Jordan Thompson defeated American Jack Sock in the first game between the two nations.
After they had split the first two sets, the American No. 1 looked the more risky, but Thompson held on to force a tie-break, and took the set when Sock double-faulted. "Let's hopefully close it out tomorrow", world No.16 Kyrgios said on court after the win. He struggled to stay with Sock in the opening set but seized his chance when the American's serve deserted him at 3-4, breaking Sock to win the opener in 37 minutes.
American captain Jim Courier had said publicly all week that he respected the tenacity and fitness of Thompson, especially in a competition with the Davis Cup's capacity for upsets.
Groth's service was the one to be broken in the second set to level the match and both Australians lost service games to drop behind 0-4 in the third set.
"The way Thommo went out there and backed himself under pressure, that's how I dreamt of his match playing out", an elated Hewitt told the press.
