Zheng Qinwen beats Iga Swiatek to reach US Open quarter-finals
After falling to No. 160 following elbow surgery, Zheng became the first qualifier since 2021 to reach the US Open quarterfinals.
Winning seven consecutive games after falling to a 0-5 deficit is a statistical anomaly in professional tennis. Doing so in back-to-back matches against two different Grand Slam title winners has never happened before.
Zheng Qinwen achieved this feat erasing a 0-5 opening-set deficit to defeat No. 8 seed Iga Swiatek 7-5, 6-3. The victory followed a near-identical recovery two days prior, when Zheng trailed Madison Keys 0-5 in a deciding set before winning seven straight games to secure the match, according to The Guardian and the Irish Times.

From Elbow Surgery to the Final Eight
Zheng's arrival in the quarterfinals marks a rapid ascent following a period of professional instability. After reaching the 2024 Australian Open final and a career-high ranking of No. 4, the Chinese star underwent elbow surgery that devastated her standing. By June, she had fallen to No. 160.
Her 2026 season began poorly, carrying an 11-13 record leading into the US Open. Forced to park her ego
and enter the qualifying draw, Zheng has since recorded seven consecutive wins in New York.
She is the first qualifier to reach this stage since Emma Raducanu in 2021. Raducanu's run ended with her becoming the first qualifier in the Open era to win a Grand Slam title, according to IB Times Australia.
While Zheng has reached the US Open quarterfinals in 2023 and 2024, she has never advanced beyond that ceiling.
The Anatomy of a Collapse
Against Swiatek, the match appeared decided early. The six-time major champion held multiple set points at 5-1 and 5-3, yet failed to close. Zheng’s resilience mirrored her performance in the 2024 Paris Olympics semi-finals, where she overcame a 4-0 second-set deficit to end Swiatek’s 25-match winning streak at Roland Garros.
| Player | US Open 2026 Status | Career High Ranking | Recent Form (Pre-Tournament) |
|---|---|---|---|
| Zheng Qinwen | Quarter-finalist (Qualifier) | No. 4 | 11-13 Record |
| Iga Swiatek | Fourth Round Exit | — | Canadian Open Winner |
Swiatek attributed the loss to unforced errors on easy balls,
rejecting claims that the collapse was mental. She told Eurosport that she simply started making too many errors while Zheng raised her level.
"I wouldn’t say it had anything to do with mentality. It was more that I started making mistakes from easy balls and Qinwen stopped doing mistakes,"

Despite receiving treatment on her left thigh during the second set, Swiatek maintained that the result was not due to physical or mental failings.
Friction in the Coaching Box
While Swiatek played down the defeat as just one match,
analysts observed signs of a breakdown between the player and her coach, Francisco Roig. Roig, former coach to Rafael Nadal, joined Swiatek’s team earlier this year, but their tactical alignment appeared fractured during the match.
Marion Bartoli, reporting for Sky Sports Tennis, noted a strong reaction from Roig when Swiatek stepped in
to attack a wide serve at 15-40 in the first set. According to Bartoli, this aggressive return is not a tactic Roig wants Swiatek to use; instead, he prefers her to stay deeper and build points with patience.
Further tension was highlighted by Martina Navratilova, who questioned the advice coming from the box. Navratilova noted that Swiatek was told to use a looser racket
because she was missing balls, a suggestion she described as peculiar
that may have left Swiatek doubting her confidence, according to Yahoo Sports.
This disconnect reflects a broader challenge in Roig's transition to solo coaching. While his 17-year tenure with Rafael Nadal established his reputation, his subsequent projects — including a 2025 effort with Emma Raducanu involving two-hour sessions on returns, have been less consistent. Toni Nadal observed that changing the habits of established players typically requires time.
Quarterfinal Landscape
Zheng's victory sets up a clash with the second seed, Elena Rybakina. Rybakina advanced by defeating Naomi Osaka 6-1, 6-4 in 1 hour and 6 minutes, producing 29 winners and 17 unforced errors. Osaka reportedly struggled with achilles pain during the match.
The stakes for Rybakina are immediate: she is now one win away from becoming world No. 1 for the first time. According to The Globe and Mail, Rybakina is guaranteed to replace Aryna Sabalenka at the top of the WTA rankings if she reaches the semi-finals.
Other quarterfinalists include:
- Mirra Andreeva: The fifth seed and French Open champion defeated Anastasia Potapova 5-7, 6-4, 6-3.
- Coco Gauff: The No. 4 seed progressed by beating Iva Jovic 6-1, 6-4.
- Alexander Blockx: In the men's draw, the 28th seed reached his first Grand Slam quarter-final by beating Francisco Cerundolo.
Frequently Asked Questions
Why was Zheng Qinwen playing in the qualifying rounds?
Zheng underwent elbow surgery earlier in the year, which caused her ranking to drop as low as No. 160 in June, necessitating her entry into the qualifying draw to reach the main tournament.
What is the significance of Swiatek's loss regarding her season?
With this exit, Iga Swiatek will finish the 2026 season without a Grand Slam title for the first time since 2021.
How does Zheng's performance compare to historical qualifier runs?
Zheng is the first qualifier to reach the US Open quarterfinals since Emma Raducanu's 2021 run, which resulted in Raducanu becoming the first qualifier in the Open era to win a Grand Slam title.
Zheng now faces the test of whether her mental resilience can push her past the quarterfinal ceiling she has hit in 2023 and 2024. Her opponent, Elena Rybakina, enters the match with the opportunity to seize the world No. 1 ranking should she advance to the semi-finals.
The fallout for Swiatek extends beyond a single loss. Following a season where her best result was a quarterfinal appearance at the Australian Open and early exits at the French Open and Wimbledon, she heads toward the Asian swing. With the China Open and Wuhan Open approaching, the primary unresolved question remains whether Swiatek will trust the tactical voice of Francisco Roig during her next crisis.
