Birthday girl wins!
Alizé Cornet celebrated her birthday Down Under with her best result since 2009 at the major. She defeated Tamara Zidanšek in three sets to set up a fourth-round meeting with Simona Halep. She will attempt to reach her first Grand Slam quarterfinal.
Taylor Fritz
The American brought the firepower to down No. 15 seed Roberto Bautista Agut in five sets. He's through to the second week of a Grand Slam for the first time in his career.
Danielle Collins
Two hours and 35 minutes. That's how long it took for the American to edge a tough Clara Tauson 4-6, 6-4, 7-5. On her fourth match point, she ripped a backhand crosscourt for a winner to secure her spot in the last 16.
Elise Mertens
It was smooth sailing for the Belgian. She rolled by Zhang Shuai, 6-2, 6-2, and is set for a fourth-round battle with Danielle Collins.
Daniil Medvedev
"Of course I don't want to stop in the fourth round, but I'm really happy."
For the fourth consecutive year the Russian eased into the Round of 16 with a straight-set victory over Botic van de Zandschulp.
