Novak Djokovic marked a rare daytime Australian Open appearance with a crushing win over Frenchman Adrian Mannarino on Sunday as the 10-times champion flirted with a 'triple bagel' before sealing a 6-0 6-0 6-3 win to reach the quarter-finals.

Djokovic, handed an early session slot at Melbourne Park for the first time since 2021, said earlier in the week he had been battling a viral affection and the world number one was coughing and appeared to be breathing heavily at times during the match.

The Serb's health issues had no impact on his play, however, and with the roof at Rod Laver Arena closed due to rain he eased to a 32nd straight match win at the tournament and a 58th Grand Slam quarter-final, equalling the all-time record of Swiss maestro Roger Federer.

"The way I played today, I don't mind playing in the day to be honest," said Djokovic, who is chasing a 25th Grand Slam to go past Margaret Court.

"It's no secret I like to play at 7 p.m. but it was not too bad today at all."

Tricky left-hander Mannarino can pose problems for the best of players by working the angles and the world number 19 pushed Djokovic hard in the opening game of the contest but still found himself down a set in only 33 minutes.

Djokovic let out a roar after breaking early in the second set, and delivered another body blow in the third game when he held serve after six deuces.

Two sets down and still not on the scoreboard, Mannarino finally won a game early in the third to draw level at 1-1, avoiding a rare "triple bagel" - 6-0 6-0 6-0 - and smiled as the crowd cheered.

Djokovic soon closed out victory, however, and said it had been one of his best performances.

"Yeah, after the first two sets, one of the best I've played in a while," he said. "I really wanted to lose that game in the third set because the tension was building up in the stadium.

"I just needed to get that one out of the way so I could refocus on what I need to do to close out the match. I played great from the first to the last point."

Djokovic, who next faces American Taylor Fritz, said slowly gaining momentum through the tournament was not something new to him.

"It's not the first time I have this particular circumstance where I start off slower and then I build as the tournament goes on," Djokovic, who won last year's title with a hamstring tear sustained in the build-up to the event, told reporters.

"Today was the best day in terms of tennis, the way I felt on court. I'm really excited to enter the second week.

"I look forward to the battles because the opponents are higher ranked ... There's no easy matches."
