Melbourne, Jan 23 (AFP) Showman Nick Kyrgios blasted Frenchman Gilles Simon off court at the Australian Open Thursday, with his raw talent shining through in front of an adoring home crowd.

The 24-year-old had the measure of the veteran early on then lost concentration and became agitated before refocusing to win 6-2, 6-4, 4-6, 7-5 on his favoured Melbourne Arena.

It set up a third-round clash with either Russian 16th seed Karen Khachanov or Sweden's Mikael Ymer, with the winner of that match on course to meet world number one Rafael Nadal in round four.

"I definitely lost my way a little bit... but I decided to refocus," Kyrgios said of his mini-meltdown in the third set.

"I could have gone to a very dark place in the fourth set but I put it away."

A seemingly more mature Kyrgios has spoken of how the bushfire crisis in his homeland has given him perspective and focus, and that he felt he was playing for the nation rather than just himself.

And with the roars of the crowd ringing in his ears, he broke the Frenchman in the first game and consolidated by holding serve.

Kyrgios looked sharp and broke again for 5-2 then served out the set, sending down five aces and, crucially, making only two unforced errors.

Simon was struggling with his serve and the Australian broke again for a 1-0 lead in the second set, making some big shots when it counted.

It went with serve before Kyrgios, watched again by his ATP Cup captain Lleyton Hewitt, won the set with another rocket serve.

He broke Simon again early in the third set, letting out a huge "C'mon!" But the Frenchman broke back as Kyrgios started to lose concentration in game eight, berating himself and gesturing to his box as frustrations kicked in.

He lost the set as his focus drifted and he yelled at his box: "Of all the things you could say, 'Stay tough'. Thanks man, thanks. That's what I get, every break point, 'Stay tough'. Wow."

But the Australian conquered his mental demons to regroup, getting a crucial break to go 6-5 up in the fourth and completing victory with a big ace, his 28th of the match. (AFP)
