Zheng Qinwen did it again.
For the second straight match at this US Open, the Olympic champion climbed out of a 5-0 hole in a set and walked off Arthur Ashe Stadium as the winner. This time, it wasn’t against a fellow outsider. It was against Iga Swiatek, a former champion in New York and one of the sport’s great front-runners.
From 5-0 down in the opening set, Zheng ripped through 13 of the next 16 games to stun the eighth seed 7-5 6-3 and surge into the quarter-finals. A qualifier, fresh off elbow surgery last year and a spell outside the top 100, just sent one of the game’s dominant forces out of the final major of the season.
From 5-0 down to total control
Zheng arrived in New York as a story of recovery rather than expectation. Elbow surgery in July 2025 had stalled her rise, dragged her out of the top 100 and left her searching for rhythm and confidence. She has found both in Flushing Meadows.
On Saturday, she trailed Madison Keys 5-0 in the deciding set of their third-round match. Keys, a former finalist here, could almost feel the finish line. Zheng never let her cross it, reeling off seven games in a row to steal the match and a place in round four.
Swiatek knew that. She still raced to 5-0 in the first set on Ashe, her heavy topspin and early striking pinning Zheng back. It looked like a routine demolition. It wasn’t.
Once Zheng settled, the match flipped. She began to step inside the baseline, take the ball earlier, and punch through Swiatek’s defences. The Chinese 23-year-old clawed her way back game by game, refusing to let the set go. At 5-5, the tension belonged to Swiatek. At 7-5, the set belonged to Zheng.
The second set started on a knife edge. Both held serve until 3-3, neither giving much away. Then came the moment that broke it open. At 3-3, 30-40, Zheng saw a second serve, read it, and uncorked a brutal backhand return winner, a clean strike that tore down the line and ripped the initiative away from Swiatek.
The pressure finally told again two games later. Zheng broke once more to close out the match 7-5 6-3, sealing a seventh straight win in New York after battling through three rounds of qualifying just to reach the main draw.
A qualifier with gold in her past and the top 50 in sight
This is not an unknown suddenly catching fire. Zheng is the reigning Olympic champion and a former world number four. She beat Swiatek in the semi-finals of the 2024 Olympics on her way to singles gold in Paris, her only previous win in eight meetings with the Pole.
The difference now is the route. She started this US Open in the qualifying draw, ranked outside the top 100 earlier this season and still rebuilding after surgery. Those extra matches have sharpened her, not drained her.
“The more matches I play, the more rhythm I have on court,” she said. Any questions about fatigue have bounced off her. “People have asked me if I'm tired and when I arrived I was not tired at all. I felt really pumped for my match, trying to reach better levels here and enjoy this fantastic stadium.”
Seven wins later, she stands on the brink of a return to the world’s top 50. She will face either Naomi Osaka, a former US Open champion, or second seed Elena Rybakina in the quarter-finals. Whoever comes through that clash will not underestimate a qualifier again.
The last woman to reach this stage in New York from qualifying was Emma Raducanu in 2021. She left with the trophy. Zheng is still several steps from that kind of miracle run, but the echoes are there.
And she is not the only qualifier reshaping the women’s game this year. At Roland Garros, Poland’s Maja Chwalinska started the tournament ranked 114th and powered all the way to the final, where she lost to Mirra Andreeva. The Russian teenager, already a French Open champion, added her own New York chapter on Monday by coming from a set down to beat Anastasia Potapova and reach her first US Open quarter-final.
Swiatek’s major season ends with a whimper
For Swiatek, this defeat closes a strangely flat Grand Slam year. The 25-year-old, who has defined recent seasons with her dominance on clay and long winning streaks, will finish 2026 without a major title for the first time since 2021.
Her best result at the Slams this year was a quarter-final in Australia. She went out in the fourth round in Paris, then saw her Wimbledon title defence crumble in the third round. New York offered a chance to reset that narrative.
Her form coming in suggested she might. Swiatek arrived on the back of a WTA 1000 title in Toronto and a semi-final run in Cincinnati. She had not dropped a set in her first three rounds here. On paper, she looked ready to make a serious push.
On court, the story changed. After her fast start, she called for treatment to her left thigh while leading 2-1 in the second set, a reminder that the body has its own say in a long season. She fought, but never fully rediscovered the control she held early in the match.
The loss leaves a gap in her year that no warm-up titles can fill. For a player of her standards, a season without a major will sting.
Zheng, meanwhile, walks away from Ashe with the kind of win that can reframe a career. From 5-0 down against Keys. From 5-0 down against Swiatek. From the qualifying rounds to the last eight.
If this is what she does while still “finding rhythm,” what happens when she feels she’s all the way back?
