Serena Williams overcame erratic strokes and two set points to beat Anastasia Potapova 7-6 (5), 6-2 Friday and reach the fourth round at the Australian Open.
The surprisingly close match entertained a modest crowd in Rod Laver Arena, but government officials announced fans will be banned from the tournament for five days beginning Saturday because of a COVID-19 outbreak at a Melbourne hotel. The Grand Slam tournament had been the first in a year to allow sizeable crowds.
Williams was eliminated in the third round at Melbourne last year, and appeared destined for the same fate until the 19-year-old Potapova became unnerved. Serving at 5-4, the young Russian held two set points but double-faulted five times and was broken.
Another wild scramble two games later swung the match even more in Williams’ direction and had her laughing before the rally ended. She chased down a drop shot at the net, retreated to retrieve a lob, and watched from near the backstop as Potapova smacked an overhead into the net.
Williams won despite losing serve three times and committing 31 unforced errors.
“I definitely feel good to be in the fourth round,” she said. “It’s about surviving and playing better every round.”
Seeded 10th, she’ll next face Aryna Sabalenka, who matched her best Grand Slam showing by advancing to the round of 16 with a win over American Ann Li, 6-3, 6-1.
Williams, 39, is again seeking to tie Margaret Court’s record of 24 Grand Slam titles. Williams won her 23rd at the 2017 Australian Open.

Sabalenka is the only woman among the top 16 seeds who has yet to reach a major quarter-final. Her best effort previously came when she earned a fourth-round berth at the 2018 U.S. Open.
“I really want to play well in the Grand Slams, go as far as I can,” Sabalenka said. “I’m trying to come out in the big stadiums and show my best.”
Sabalenka, 22, has won 23 of her past 26 matches.
Later matches on the men’s side included eight-time Australian Open champion Novak Djokovic against American Taylor Fritz.
In other third-round play, No. 14-seeded Garbine Muguruza defeated Zarina Diyas 6-1, 6-1. No. 19 Marketa Vondrousova beat Sorana Cirstea 6-2, 6-4.
