NOVAK DJOKOVIC AVOIDED his struggles of the first two rounds in a straight-sets win over Tomas Martin Etcheverry at the Australian Open on Friday.

His fellow defending champion, Aryna Sabalenka, routed Lesia Tsurenko 6-0 6-0 while 16-year-old Mirra Andreeva recovered from 5-1 down in the deciding set to beat Diane Parry.

It was generally a good day for the big names, with Coco Gauff, Jannik Sinner and Stefanos Tsitsipas also winning.

Djokovic has been struggling with illness and was well short of his best in his first two matches, particularly a second-round clash with Alexei Popyrin on Wednesday that he was lucky to escape.

But Djokovic, playing his 100th match at Melbourne Park, looked much more like his usual self in a 6-3 6-3 7-6 (2) victory over Argentina’s Etcheverry, who beat Andy Murray in the first round.

The Serbian was hitting his groundstrokes with their customary ferocity again and, although there were perhaps still a few more mistakes than he would have liked, he was always fully in control of his 92nd win on these grounds.

Djokovic said: “It was a great match, the best performance I had during this tournament. I’m pleased with the way I played throughout the entire match, particularly the first two sets.”

Next the top seed will take on French veteran Adrian Mannarino, who upset 16th seed Ben Shelton in a five-set battle. 

The form players of the first week have been fourth seed Jannik Sinner and big home hope Alex De Minaur.

Sinner finished last season beating Djokovic twice in one day as he led Italy to the Davis Cup title and has eased through to the fourth round here.

He dropped just four games in a 6-0 6-1 6-3 destruction of Sebastian Baez to set up a meeting with Russian Karen Khachanov, who was a semi-finalist here last year.

De Minaur’s rise into the top 10 just before the tournament fuelled hopes of a first home winner of the men’s singles since Mark Edmondson in 1976, and he has dealt with the pressure immaculately so far.

The 24-year-old had no trouble getting past Italian qualifier Flavio Cobolli, dropping only seven games in a 6-3 6-3 6-1 victory.

De Minaur, who has never been beyond the fourth round in Melbourne, next takes on fifth seed Andrey Rublev, who defeated Sebastian Korda 6-2 7-6 (6) 6-4.

Last year’s runner-up Stefanos Tsitsipas also had a comfortable afternoon, beating young Frenchman Luca Van Assche 6-3 6-0 6-4 to set up a clash with American 12th seed Taylor Fritz, who came from a set down to see off Fabian Marozsan 3-6 6-4 6-2 6-2.

Meanwhile, Sabalenka handed Lesia Tsurenko the dreaded double bagel at the Australian Open – but the scoreline did not bother the Ukrainian.

The defending champion’s 6-0 6-0 victory means she has cruised through to the fourth round in Melbourne for the loss of only six games.

At the end of the match there was no handshake, as has been standard between Ukrainian players and those from Russia and Belarus since the start of the war nearly two years ago, although the pair did both put their hands up to acknowledge each other.

Fourth seed Coco Gauff has also been in impressive form and she eased to a 6-0 6-2 victory over fellow American Alycia Parks.

Anisimova, meanwhile, beat another player on the comeback trail in Spain’s Paula Badosa 7-5 6-4 despite battling stomach cramps.

“I’m really proud of myself,” said Anisimova, who first made the fourth round here five years ago as a 17-year-old.

“I wasn’t sure should I expect to do well because a lot of people were telling me, ‘Don’t put too much expectations on yourself’. I’m just really happy that I was able to get this far, but I still think that I can do more.”
