She will next face French eighth seed Caroline Garcia, who was too strong for Belarussian Alaksandra Sasnovich. Along the way, he has won five of his 19 Grand Slam singles titles. Answer: All of them have beaten Australian Open champions.
"I feel like I transported myself into the TV this year and I'm finding myself on Rod Laver Arena competing".
It was Barty, though, who drew the sympathy of a disappointed crowd.
This time around the Russian got the job done 6-1 7-6 (7-4) against the 14th seeded Latvian.
They were hopes that evaporated as Osaka dominated from the first serve.
"I was consistent but I was looking to come forward and I played really well at the net".
"So thank you very much because I've never played in an atmosphere like this before. I'm nearly dead", Halep said of the match which equaled Chanda Rubin's win over Arantxa Shanchez Vicario in 1996 also 48 games for the Australian Open record in terms of most games.
Six-time Australian Open champion Novak Djokovic continued his comeback from six months out with an injured right elbow with a 6-2, 6-3, 6-3 win over No. 21 Albert Ramos-Vinolas to move into the fourth round for a sixth consecutive major.
Kerber, the 2016 victor, will meet in the fourth round clash either Agnieszka Radwanska or Hsieh Su-wei.
The German 21st seed is the last remaining major victor in the women's field following a streak of first-week upsets.
It was the most anticipated match of the tournament so far but Kerber carried on the tremendous form she has shown to start the season and romped to a 6-1 6-3 victory in just 64 minutes.
A fluffed drop shot attempt at 3-4 followed by an unforced error gave 2016 champion Kerber breathing space and she finished the contest in the next game.
Under the lights at Rod Laver Arena, Kerber's forehand did all the damage for Sharapova, who is still trying to find her feet in the women's singles after a 15-month doping ban.
The match was a clash between the only two former champions in the draw and Kerber is looking ominously like the player who won her maiden slam in Melbourne two years ago before going on to win Wimbledon and finish 2016 as world number one. "So as incredible as that run was, the combination of being exhausted from that and having a wrist that still wasn't 100 percent flawless, I just needed to kind of shut it down, calm down, and then I was really excited to start the new season".
"It was a tough match, it always is against Lucie", said Pliskova, who made the quarter-finals previous year. "But I'm here because I'm motivated to get better at my craft".
