MELBOURNE - Title contenders Jannik Sinner, Aryna Sabalenka, Coco Gauff and Stefanos Tsitsipas all made light work of their third-round ties at the Australian Open on Friday to storm into the second week of the year’s first Grand Slam.

After a day of close scrapes, marathon tiebreaks and upsets at Melbourne Park on Thursday, the leading seeds were ruthlessly efficient in booking their spots in the fourth round on day six of the championships.
