By Shrivathsa Sridhar MELBOURNE (Reuters) -Defending champion Aryna Sabalenka overcame a wobbly display to reach the Australian Open fourth round while Novak Djokovic and Carlos Alcaraz were at their dazzling best on a warm but windy Friday at Melbourne Park.

Coco Gauff still hasn't lost a match or even at set at the Australian Open — or, actually, this season. She moved into the fourth round at Melbourne Park with a straightforward 6-4, 6-2 victory over 2021 U.

Aryna Sabalenka stayed on track for an Australian Open hat-trick Friday, while later Coco Gauff and Naomi Osaka can set up a blockbuster clash and Novak Djokovic steps up his quest for a record 25th Grand Slam title.
