The support from the crowd in Queens was audible as she came from behind to win the first set and took command in the second set. Osaka has won six of her last eight matches on hard court. And that the fans were responding to this tournament's juiciest fixture since Serena Williamsplayed Maria Sharapova on the opening night. "I think she shows us how to compete and the way to, like, be off the court, too". Ahn didn't and kept playing.
Reigning Wimbledon champion Simona Halep, meanwhile, crashed out early in NY for a third year running, blowing a match point in a tense three-set loss to 116th-ranked Taylor Townsend.
Like everyone else following the U.S. Open this week, even Serena is caught up in Coco Fever.
Gauff is now ranked 140th, which would have been too low to get her into the field at Flushing Meadows, but the U.S. Tennis Association opted to ignore the WTA's age eligibility rule limiting how many wild cards someone her age can be offered and gave her one, anyway.
Viewership for the match peaked at 2.16 million late in the match, which Gauff pulled out in front of 14,000 at the main Louis Armstrong Stadium. The jeers reached a crescendo after Medvedev's win was done, and he seemed to relish it and egged the spectators on. "I think we're all a bit surprised that she's able to back it up after Wimbledon, you know, which was already an incredible run". Federer has started his first two matches in a strikingly low gear, dropping sets in each match before recording the wins. Osaka won the 2019 Australian Open after taking down Serena Williams at the U.S. Open previous year, but hasn't advanced past the third round in each of the last two Grand Slams. And I would love to do it.
Wozniacki, the No. 19 seed and last year's Australian Open champion, also appeared to be bothered by a right ankle that she had retaped courtside midway through the match.
The American world number 116, who stunned Wimbledon champion Simona Halep in round three, beat Cirstea 7-5 6-2. Her second-round matchup went much smoother as Osaka cruised to a 6-2, 6-4 victory over Linette.
Belgian 25th seed Elise Mertens swept into the fourth round for a second year running with a 6-3, 6-3 defeat of Germany's Andrea Petkovic.
The 23-year-old Townsend is enjoying her deepest run, surpassing her third-round showing on debut at the 2014 French Open, and will play 15th seed Bianca Andreescu for a quarter-final spot.
But it's clear there's something happening out here in Queens - and it will only get bigger on Saturday in the world's biggest tennis stadium against the top-seeded Osaka, who has been compromised by a knee injury that forced her to retire from a quarter-final match in Cincinnati less than two weeks ago.
15-year-old American sensation Cori "Coco" Gauff, won a thrilling three set match against Timea Babos 6-2, 4-6, 6-4 to advance to the third round as well, where she will play Osaka.
First came a victory over Williams' older sister, five-time Wimbledon champ Venus.
