MELBOURNE, Australia (AP) — A quick look at the Australian Open:

LOOKAHEAD TO SATURDAY

There will be no spectators allowed on site for Day 6 of the Australian Open as a lockdown imposed by the Victoria state government begins because of new COVID-19 cases in the area. Rafael Nadal continues his attempt for a men’s-record 21st Grand Slam singles title when he takes on Cameron Norrie, while three American women will attempt to join Serena Williams in the fourth round. Shelby Rogers will play No. 21 Anett Kontaveit, No. 22 Jennifer Brady takes on qualifier Kaja Juvan and Jessica Pegula faces Kristina Mladenovic. Kaia Kanepi, who beat defending champion Sofia Kenin in the second round, plays Donna Vekic, while top-ranked Ash Barty plays Ekaterina Alexandrova. Men's matches include Australia's Alex De Minaur against the volatile Fabio Fognini, who got into a heated exchange with fellow Italian Salvatore Caruso after a five-set win on Thursday and had to be separated by a tournament official. No. 4 Daniil Medvedev, No. 5 Stefanos Tsitsipas and No. 7 Andrey Rublev all are also in action Saturday.
