Australian Nick Kyrgios produced another extraordinary performance to demolish compatriot Alex de Minaur 6-2 6-3 at the Canadian Masters on Thursday, a day after stunning world number one Daniil Medvedev.

The fiery Wimbledon finalist has been playing the best tennis of his career and is showing no signs of slowing down in Montreal, where he won the first four games of the opening set in which de Minaur won scarcely more than half of his first-serve points.

Nick Kyrgios and Alex de Minaur traded breaks to open the second set but 27-year-old Kyrgios would not be denied, breaking de Minaur on the third try in the third game and again in the seventh

The pair traded breaks to open the second set but 27-year-old Kyrgios would not be denied, breaking de Minaur on the third try in the third game and again in the seventh.

Kyrgios briefly appeared agitated when he gave up a break in the penultimate game but found his composure to get the job done in a little over an hour, breaking back to love in the final game.

The win will move Kyrgios high enough in the rankings to be seeded at the US Open later this month.

"I did what had to be done. He's a hell of a player if you play to his strengths, he's one of the best players from the back in the game, he's just so fast," Kyrgios said of de Minaur in on-court remarks after the match.

Kyrgios has won 15 of his last 16 matches and a day earlier produced a serve-and-volley masterclass to stun Medvedev 6-7(2) 6-4 6-2. He said the effort had certainly taken a toll.

"Incredibly tough, after yesterday's big high-playing Daniil. The crowd was amazing, it's a day I'll probably never ever forget," he said.

"Today was really hard for me mentally to play Alex, we're such good friends and he's been having such a good career so far carrying the Australian flag. It's just tough mentally, it's never easy to play a friend like that, especially if they're an Australian."

Superb Auger-Aliassime

In other matches, Felix Auger-Aliassime harnessed his mighty serve to down Briton Cameron Norrie 6-3 6-4 to delight his home crowd, while Norwegian Casper Ruud outlasted Roberto Bautista Agut in a closely-fought three sets.

Competing in his local town of Montreal, the 22-year-old Auger-Aliassime sent over 15 aces and won all but three of his first-serve points, breaking in the penultimate game of both sets on Centre Court.

British number one Norrie made five double faults and never had the momentum against a clinical Auger-Aliassime, who collected his first ATP title in Rotterdam this year and wrapped up Thursday's affair in a tidy 72 minutes.

"Montreal people are really proud people," Auger-Aliassime was quoted as saying by the ATP, crediting the crowd with helping his performance.

"We are a small community in the world. We support each other in what we do, especially in professional sport."
