The US Open, a Grand Slam steeped in dramatic comebacks and unexpected upsets, witnessed another chapter of its storied history unfold on Arthur Ashe Stadium as Chinese phenom Zheng Qinwen once again defied the odds, stunning world number one Iga Swiatek in a captivating fourth-round encounter. Zheng, who had already authored a remarkable comeback from 5-0 down in the previous round, replicated the feat against the formidable Pole, ultimately clinching a remarkable 7-5, 6-3 victory to secure her maiden appearance in the US Open quarter-finals.
This electrifying performance marks a significant milestone for the 23-year-old from China, who has steadily climbed the ranks with a blend of raw power and unwavering mental fortitude. Her journey to this stage has been nothing short of spectacular, especially considering the recent challenges she has faced. Earlier in the year, Zheng found herself outside the top 100, a stark contrast to her previous standing as a top 10 player. This dip was largely attributed to an elbow surgery performed in July 2025, a period that tested her resolve and resilience. However, her resurgence in New York has been a testament to her dedication and the quality of her game.
The sheer improbability of Zheng’s comeback against Swiatek cannot be overstated. In the opening set, the Chinese player found herself staring down a daunting 5-0 deficit. The pressure of facing the reigning Olympic champion and a multiple Grand Slam winner like Swiatek would have been enough to deter many. Yet, Zheng displayed an astonishing level of composure and tactical brilliance, winning 13 of the next 16 games to seize control of the set. This dramatic turnaround set the tone for the remainder of the match, demonstrating a psychological edge that has become her hallmark in this tournament.
The second set continued on serve until the pivotal seventh game. With the score delicately poised, Zheng unleashed a thunderous backhand return winner, a shot that not only secured a crucial break but also visibly rattled Swiatek. Building on this momentum, Zheng broke the Polish star’s serve once more two games later, sealing her place in the quarter-finals with a commanding 7-5, 6-3 victory. This win extends her current winning streak in New York to an impressive seven matches, a run that began in the qualifying rounds and has propelled her back towards the top 50 of the WTA rankings.
"The more matches I play, the more rhythm I have on court," Zheng stated in her post-match press conference, her voice exuding confidence. "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." Her words reflect a player who is not only physically prepared but also mentally invigorated by the tournament atmosphere and her own performances.
The echoes of Zheng’s previous comeback in the third round against Madison Keys resonated throughout her encounter with Swiatek. In that match, Zheng had also trailed 5-0 in the deciding set before mounting an improbable seven-game surge to snatch victory. To witness a repeat of such a dramatic turnaround against one of the sport’s most dominant figures underscores Zheng’s extraordinary mental fortitude and her ability to perform under immense pressure. This pattern suggests a player who thrives in adversity, finding an extra gear when her back is against the wall.
A Tournament of Comebacks and Rising Stars
The US Open has a rich history of producing unforgettable comebacks, and Zheng’s performances this year are firmly etched into that narrative. Her victory over Swiatek is particularly significant, given their previous encounters. Zheng’s only previous win against Swiatek came in the semi-finals of the 2024 Olympic Games in Paris, a match that ultimately led to her gold medal triumph. This latest win not only avenges previous losses but also reasserts her claim as a major contender on the Grand Slam stage.
Zheng’s quarter-final opponent will be determined by the outcome of the highly anticipated match between former US Open champion Naomi Osaka and second seed Elena Rybakina. Regardless of the opponent, Zheng’s current form and fighting spirit suggest she will be a formidable challenge.
Former world number five Daniela Hantuchova, speaking to BBC Radio 5 Sports Extra, lauded Zheng’s current trajectory. "She is starting to be very dangerous for the rest of the players left," Hantuchova commented. "I don’t want to say she’s playing the best tennis out of everyone, but if you have Iga Swiatek panicking on the other side of the court, not knowing what to do, that says a lot." This sentiment highlights the significant impact Zheng’s play has had on her opponents, even those at the very pinnacle of the sport.
The Resurgence of the Qualifier
Zheng’s impressive run is also drawing parallels to the remarkable Cinderella stories that have graced the US Open in recent years. The most recent qualifier to reach the latter stages of the women’s draw was Great Britain’s Emma Raducanu, who sensationally went on to win the title in 2021. This precedent offers a glimmer of hope and inspiration for players who enter Grand Slams without the highest rankings.
Furthermore, 2026 has seen other qualifiers make significant impacts at Grand Slam events. Poland’s Maja Chwalinska, who entered the French Open ranked 114th in the world, reached the final at Roland Garros before ultimately falling to Russian teenager Mirra Andreeva. These narratives underscore a growing trend of lower-ranked players challenging the established order and achieving unexpected success.
Swiatek’s Disappointing Grand Slam Finale
For Iga Swiatek, this fourth-round exit represents a premature end to her Grand Slam campaign for the year. Her best performance in a major in 2026 was reaching the quarter-finals of the Australian Open. The French Open saw her eliminated in the fourth round, and her defense of the Wimbledon title concluded in the third round. This marks the first time since 2021 that Swiatek will finish a year without securing a Grand Slam title, a statistic that will undoubtedly fuel her determination for the upcoming season.
Swiatek had entered the US Open in formidable form, having triumphed at the WTA 1000 event in Toronto and reaching the semi-finals in Cincinnati. Her progression through the initial rounds in New York had been equally dominant, as she had not dropped a single set. This made her defeat to Zheng all the more surprising.
Reflecting on her loss, Swiatek admitted to making too many unforced errors after her initial strong start. "My focus was the same as always," she stated. "I wanted to play the same as always. [I] just started to miss too much, wanted to adjust it, but nothing kind of worked at that point. I knew I was going to have another chance and I wanted to use it, but I missed them all."
The world number one further elaborated on the psychological aspect of the match, stating, "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. She played the balls better." This candid admission highlights Zheng’s ability to capitalize on opportunities and maintain a high level of play, while Swiatek struggled to regain her rhythm. Swiatek also received treatment for a left thigh issue during the second set, though she did not attribute her loss directly to the injury.
Andreeva Advances After Grueling Battle
In another compelling fourth-round match, Mirra Andreeva, the fifth seed, battled her way into the quarter-finals for the first time in her career at the US Open. The 19-year-old Russian emerged victorious against her compatriot Anastasia Potapova, the 24th seed, in a hard-fought contest that concluded with a score of 5-7, 6-4, 6-3.
The match was a grueling affair, marked by intense rallies and significant physical exertion. The turning point came in the final game of the match, when Potapova appeared to twist or hyperextend her knee while attempting to retrieve a shot. Andreeva, showing great sportsmanship, immediately rushed to her opponent’s aid. Despite receiving treatment and attempting to continue, Potapova was ultimately unable to complete the game, signaling the end of her tournament.
"Anastasia is my good friend and seeing what a battle we had and seeing her fall like that in the last game, it’s not easy," Andreeva shared, her concern for her opponent evident. "I told her that she’s been playing amazing and having one of her best seasons. I’m sure she’ll come back even stronger – she’s a warrior and an even better fighter than me." Her words underscore the camaraderie that exists within the WTA tour, even amidst fierce competition.
Andreeva’s quarter-final opponent will be the winner of the all-American fourth-round clash between Coco Gauff and Iva Jovic, a match scheduled for Monday’s night session. With her strong performance and a growing reputation, Andreeva is now a significant contender in the bottom half of the draw.
The US Open continues to deliver thrilling tennis, with Zheng Qinwen’s remarkable resilience and Iga Swiatek’s unexpected exit adding significant drama to the tournament. As the competition progresses, all eyes will be on these emerging stars and established champions as they vie for Grand Slam glory.
