Australian Open | Melbourne
Top seed Novak Djokovic survived a scare to overcome Denis Shapovalov in four sets at the Rod Laver Arena.
The world number one strolled into a two-set and 4-1 lead before losing five consecutive games to force a fourth set.
But the Serb brushed off any signs of complacency, hitting back with a bagel in the final set to seal his place in the last 16.
There were also wins for top 20 seeds Milos Raonic, Kei Nishikori and Daniil Medvedev, who all progressed in straight sets.
In the women's singles, Serena Williams enjoyed a comfortable passage into the fourth round with a 6-2, 6-1 victory over Ukrainian teenager Dayana Yastremska.
But No. 6 seed Elina Svitolina had tougher time, fighting from a set down to defeat Shuai Zhang 4-6, 6-4, 7-5 in an epic encounter that lasted three hours.
Simona Halep defeated Venus Williams in the evening session, and now the World No.1 will face Serena Williams in the next round - what a mouth-watering class that is!
