Chung is through to the fourth round of a grand slam for the first time after knocking out fourth seed Alexander Zverev. "We had a good agreement, in my opinion, that made the Grand Slams happy, the players pretty happy". It's fine. I finished the match.
Djokovic had not played a competitive match for six months before his first-round clash with American Donald Young and while that was a breeze, his clash with Monfils in 40 degrees heat proved to Agassi that the 30-year-old is battle ready.
"I'm looking forward to playing against her", the German said.
"I knew before the match it would be a tough one".
It was nearly 40 degrees Celsius when Djokovic and Monfils were doing battle on Rod Laver Arena, so dropped to around 30°C by the time Federer defeated Struff 6-4 6-4 7-6 (7-4).
Fifth-seeded Dominic Thiem beat Adrian Mannarino 6-4, 6-2, 7-5 to set up a fourth-round match against Tennys Sandgren, who continued his career-best run by beating Maximilian Marterer 5-7, 6-3, 7-5, 7-6 (5).
The five-time grand slam champion lost to Sevastova at the US Open past year and won a tight thriller in Beijing, leaving her pleased with a much more convincing victory on a hot day in Melbourne.
As much as this was a resounding declaration of Kerber's return to top form, it also showed just how much progress Sharapova has to make as she orchestrates her own return.
"They are having tough times out there", said the 81st-ranked Croatian.
"I have so many good memories on this court", said Kerber, who won her first Grand Slam title there two years ago when she beat Serena Williams in the final.
Former No. 1-ranked Angelique Kerber, the 2016 Australian Open victor, continued her resurgent run with a 6-0, 6-4 victory over Anna-Lena Friedsam to extend her streak to 10 consecutive victories. It has always been, not just for tennis, but in general there's always something that you can improve and get better at as a person and as a player.
"I know Marton a little bit", Federer said.
Kerber streaked away with the first set, aided by the erratic nature of Sharapova's game, and although the 2008 champion briefly threatened a fightback after falling behind in the second, it was not to be the Russian's night.
Taiwan's Hsieh Su-Wei claimed the biggest upset so far, knocking out third seed Garbine Muguruza 7-6 (7-1), 6-4.
During an on-court interview with Channel Seven's Courier after his 6-2 7-5 6-4 victory over Frenchman Richard Gasquet, the victor of 19 Grand Slams was put on the spot.
The Frenchman, known as one of the fittest players on tour, looked dazed and confused in the second set and eventually got medical assistance.
