Last year's runner-up, Aryna Sabalenka, overcame a shaky display after the latest start to a match at the US Open for a 2-6 6-1 6-2 third-round win over 29th seed Ekaterina Alexandrova in the early hours of Saturday morning.
Sabalenka and Alexandrova walked onto Arthur Ashe Stadium with fans still catching their breath after Alexei Popyrin upset defending champion Novak Djokovic late Friday night. The duo began their match only at 12:08 a.m.
The previous latest recorded start at the tournament came in 1987 when Gabriela Sabatini and Beverly Bowes took to the court at midnight and wrapped up in 90 minutes.
A quick finish seemed unlikely after Australian Open champion Sabalenka's game went off the rails amid a string of unforced errors, and the second-seeded Belarusian dropped the opening set in 33 minutes.
"I don't know what I did. I was just trying to stay low and put as many balls as I could back on that side. She played incredible tennis in the first set. It was really tough to change it," Sabalenka said.
The 26-year-old quickly found her groove, broke for a 3-1 lead in the next set, and never looked back after that, levelling the contest with a breathtaking display of power to overwhelm her spirited Russian opponent.
"I'm really happy I was able to turn around this match and get this really difficult win."
Sabalenka was surprisingly broken after going up 5-0 in the decider, but she promptly delivered the knockout blow to a fading Alexandrova with a backhand winner to delight the crowd that stuck around.
"Thanks so much for staying that late," Sabalenka said as the clock neared 2 a.m.
