Djokovic, Sabalenka in ruthless form to reach Australian Open quarterfinals

MELBOURNE, Australia -- Novak Djokovic was at his dominant best in a straight-sets demolition job to reach the Australian Open quarterfinals on Sunday, with Aryna Sabalenka and Coco Gauff in equally ruthless touch.

The Serbian superstar recaptured his top form to surge into the last 16 after dropping sets in his opening two matches while feeling ill, and he stepped up another level against Adrian Mannarino.

The French 20th seed, who at 35 is a year younger than Djokovic, has been enjoying a late career resurgence.

But he was taught a lesson by the world number one, who won the first 13 games in powering through to the last eight of a Grand Slam for the 58th time, equalling Roger Federer's men's record.

"I played great, from the first to the last point," said the defending champion, who is red-hot favourite to collect an 11th Melbourne title and a record 25th Grand Slam crown.

"It's going in a positive direction, health-wise, tennis-wise so I'm really pleased with where I am at the moment."

Djokovic almost always plays the night session on Rod Laver Arena, but was bumped to the afternoon this time.

That's because home hope Alex de Minaur, seeded 10, is bidding to make the last eight for the first time, with Russian fifth seed Andrey Rublev standing in his way.

In other fourth-round action, in-form fourth seed Jannik Sinner faces last year's semifinalist Karen Khachanov.

The man who beat him in that semifinal, Stefanos Tsitsipas, who is the seventh seed, takes on 12th-seeded American Taylor Fritz for the right to meet Djokovic next.

- 'An honour' -
Defending women's champion Sabalenka has been in imperious form and was in complete charge against unseeded Amanda Anisimova on Margaret Court Arena, sweeping past the American 6-3, 6-2.

Fourth seed Coco Gauff, attempting to become the first woman to back up a US Open title with a Grand Slam win in Australia since Naomi Osaka in 2018-19, has been almost as impressive.

She swatted aside Poland's unseeded Magdalena Frech 6-1, 6-2 in just 63 minutes on Rod Laver Arena, with the 85-year-tennis legend watching from the stands.

"It was an honour to play in front of you, so thank you for coming to my match," said 19-year-old
