MELBOURNE, Australia — Another day, another record crowd. Top-ranked Aryna Sabalenka and Carlos Alcaraz advanced in straight sets Wednesday and the No. 3 seeds — Coco Gauff and Alexander Zverev — also progressed to the third round of the Australian Open.
The combined numbers for day and night sessions, 103,720 fans, set a full-day record for the third time in four days of the main draw at the season-opening major, which has become a festival of tennis.
Two-time Australian Open champion Sabalenka opened Day 4 with a 6-3, 6-1 win over Bai Zhouxuan on Rod Laver Arena, and Gauff beat left-hander Olga Danilovic 6-2, 6-2 at Margaret Court Arena.
Alcaraz fended off Yannick Hanfmann 7-6 (4), 6-3, 6-2 in an afternoon encounter on the center court, and then reflected on his own performance and on his golf outing with Roger Federer.
''I didn't see myself playing that good but then talking to my team, I realized that I played better than I thought,'' he said of his tough outing against the free-hitting Hanfmann. ''I'm still getting used to the conditions, getting used to playing better.''
Alcaraz, 22, is trying to win his first title at Melbourne Park to become the youngest man to complete a career Grand Slam.
Zverev, who lost last year's final here to Jannik Sinner, had to wait through a half-hour rain delay and concern over a sore left ankle before beating Alexandre Muller 6-3, 4-6, 6-3, 6-4.
He was leading the fourth set 2-1 and serving at 15-0 when he had to halt the match and sit in a courtside chair for treatment.
