Defending champion Carlos Alcaraz continued his pursuit of a third U.S. Open title Friday, while Aryna Sabalenka overcame an unusual distraction at Flushing Meadows to reach the fourth round.
Sabalenka was briefly distracted by the smell of cannabis drifting through the sprawling U.S. Open complex, but the top seed kept her focus on the court and advanced.
Former champion Daniil Medvedev also moved into the fourth round, defeating Arthur Rinderknech to maintain his push among the tournament's leading contenders heading into the second week.
The evening session at Arthur Ashe Stadium brought a nostalgic reunion for tennis fans as former U.S. Open doubles champions Venus and Serena Williams returned to the court together.
The sisters rolled back the years but ultimately fell to Maya Joint and Chan Hao-ching 6-3, 6-7 (6), 7-6 (10-7).
Alcaraz showed little sign of rust after missing more than four months with a wrist injury. The Spaniard looked sharp on the tournament's main showcourt, cruising past China's Wu Yibing 6-3, 6-4, 6-1 to remain on course for another championship run.
"After four months without competing ... when you play an official match with the nerves and everything, the day after or right after, your body can feel really tight," Alcaraz said.
"It didn't happen to me, and I'm feeling better and better after every match. It feels like I've been competing the whole time. I've surprised myself with the way I'm recovering after every match."
The seven-time Grand Slam champion next meets Tommy Paul after the American 20th seed beat Alexander Bublik 6-4, 3-6, 6-7 (4), 6-1, 6-3.
Medvedev remained unblemished with a 6-4, 6-4, 6-4 win over Rinderknech, while Valentin Vacherot went out after a 6-4, 6-2, 6-4 defeat by 11th seed Frances Tiafoe.
Stefanos Tsitsipas continued his resurgence with a 2-6, 6-1, 7-6 (3), 6-1 victory over 18th seed Jiri Lehecka before Mariano Navone, who stunned Novak Djokovic in the first round, crashed out 6-4, 6-4, 6-3 to Tomas Martin Etcheverry.
American fans left disappointed by the Williams sisters' defeat had reason to cheer late at night when home hope Ben Shelton beat Denis Shapovalov 7-6 (3), 6-7 (5), 6-3, 6-4.
Shelton, a U.S. Open semifinalist in 2023, will next face Tsitsipas, the former Australian Open and French Open runner-up.
"I have been watching his matches. I think he's playing great," Shelton said of Tsitsipas, who upset Cincinnati champion Arthur Fils in the opening round.
"I think that his style of tennis can be very, very effective on all surfaces, all-court game, great athlete.
"We played once my first year on tour. Really looking forward to it."
Sabalenka's pre-tournament form had raised plenty of concerns, but the top seed looked to have left her slump behind as she did not face a single break point in her 6-3, 6-4 victory over Uzbekistan's Kamilla Rakhimova.
Her only issue during the morning session was the smell of cannabis drifting into Louis Armstrong Stadium, prompting her to stop play and alert the chair umpire.
"Someone is smoking weed," the Belarusian said as she walked up to the chair umpire.
"Do you mind? Because it's so strong."
While smoking is not allowed inside the U.S. Open grounds, recreational cannabis is legal in New York, and smoke from the surrounding Flushing Meadows-Corona Park can drift into the tennis venue.
Sabalenka said she did not object to anyone enjoying themselves and relaxing but called for smoking to be kept away from the courts.
"I was like, 'guys, you can do whatever, you can smoke whatever, you can relax as much as you can, but please not around the tennis courts,'" she added.
"It's a bit tricky to handle that smell while you're trying to compete at your best."
Sabalenka's focus will now shift to American Taylor Townsend, who set up a clash with the four-time major winner after seeing off Diana Shnaider 6-2, 6-7 (3), 6-3.
Jessica Pegula gave fellow former U.S. Open runner-up Leylah Fernandez hope before coming back in style to seal a 1-6, 6-4, 6-3 win. The American third seed will next meet Sorana Cirstea.
Ukraine's 11th seed Marta Kostyuk beat Ekaterina Alexandrova 6-3, 6-2 and next takes on Wimbledon champion Linda Noskova, who beat Ann Li 6-2, 6-7 (6), 6-2.
It was the end of the road for Kostyuk's compatriot Elina Svitolina, who was beaten 6-3, 2-6, 6-3 by Anna Kalinskaya.
Wimbledon runner-up Karolina Muchova was unable to keep her strong Grand Slam form going as the seventh seed was beaten 6-3, 7-5 by Emma Navarro, who joined the American march into the weekend at the tournament.
