NEW YORK, United States – September 9, 2026: Elena Rybakina arrived at Arthur Ashe Stadium needing one victory to reach her first US Open semifinal and secure the World No. 1 ranking for the first time in her career.
Zheng Qinwen made her earn every bit of it.
The Chinese qualifier took the opening set and threatened to extend one of the most remarkable runs of the 2026 US Open, but Rybakina responded with a devastating second-set turnaround before holding her nerve through a tense decider to win 3-6, 6-1, 6-4.
The victory sends the No. 2 seed into the semifinals in New York for the first time and completes another major milestone in a season that has already included the Australian Open title.
More significantly, the win gives Rybakina enough ranking points to move above Aryna Sabalenka and become World No. 1 for the first time.
Zheng leaves the tournament without the semifinal place she wanted, but with her status among the world’s elite restored after an injury-disrupted year had pushed her outside the Top 100 and forced her through qualifying.
For more than two sets, she made Rybakina confront exactly why her comeback has become one of the defining stories of this US Open.
What Was the Zheng Qinwen vs Elena Rybakina Final Score?
| Player | Set 1 | Set 2 | Set 3 | Result |
|---|---|---|---|---|
| Zheng Qinwen | 6 | 1 | 4 | Lost |
| Elena Rybakina | 3 | 6 | 6 | Won |
Rybakina defeated Zheng 3-6, 6-1, 6-4 in the women’s singles quarterfinal at Arthur Ashe Stadium.
It was Rybakina’s first three-set match of the tournament after she had reached the quarterfinals without dropping a set.
It was also the first time in New York this year that an opponent had forced her to recover from a set down.
How Did Elena Rybakina Come Back to Beat Zheng Qinwen?
The match changed because Rybakina refused to let a poor opening set become a poor match.
Zheng began with the aggression and confidence that had carried her through qualifying and through victories over two Grand Slam champions.
She took the first set 6-3 and, for the first time in the tournament, Rybakina was no longer dictating the terms of a match from the front.
The response was immediate.
Rybakina increased the pressure behind her first strike, shortened the exchanges and began taking time away from Zheng from the baseline.
The second set lasted only long enough for the direction of the match to change completely.
Rybakina won it 6-1.
The quarterfinal had gone from a possible upset to a one-set shootout for the semifinals and the World No. 1 ranking.
Why Was the Third Set So Tense?
Zheng had already shown throughout this tournament that she is extraordinarily difficult to finish.
She had survived situations that should have ended matches against her.
Against Madison Keys, she recovered after falling 5-0 behind in the deciding set.
Against Iga Swiatek, she again found herself 5-0 down, this time in the opening set, and somehow won it 7-5 before completing a straight-sets upset.
The Sports Encounter covered that extraordinary escape in our report on Zheng’s comeback against Swiatek.
Rybakina therefore knew that reaching the final set was not the same as controlling it.
Zheng stayed with her.
The rallies became more consequential, the service games carried more pressure and neither player could afford the kind of extended dip that had decided the second set.
Rybakina eventually found the separation she needed and closed the decider 6-4.
That final break of resistance carried considerably more weight than an ordinary quarterfinal finish.
Did Elena Rybakina Become World No. 1 by Beating Zheng?
Yes.
The ranking equation entering the quarterfinal was unusually simple.
Rybakina needed to reach the semifinals to guarantee enough points to move above Sabalenka in the post-US Open WTA rankings.
The official US Open ranking analysis confirmed that beating Zheng would make Rybakina the 30th woman to reach No. 1 in the history of the WTA rankings.
That means the ranking race is no longer dependent on what Sabalenka, Jessica Pegula or Coco Gauff do later in the tournament.
Rybakina has taken control herself.
The Sports Encounter had been tracking this possibility before the quarterfinals in our detailed US Open World No. 1 ranking race analysis.
At that point, the mathematics showed why Rybakina controlled the entire equation.
Now the mathematics have become a result.
Why Is Rybakina Reaching World No. 1 So Significant?
The ranking represents more than one strong fortnight in New York.
Rybakina came into the US Open already carrying one of the strongest season-long records on the WTA Tour.
She won the Australian Open earlier in 2026 and entered New York ranked a career-high No. 2.
The official US Open noted before the quarterfinal that she had accumulated 46 tour victories this season, trailing only Jessica Pegula at the time.
She had also won two titles, finished runner-up at two additional tournaments and reached another semifinal.
Her ranking rise therefore reflects accumulated performance rather than a two-week spike.
How Did Rybakina Reach the US Open Quarterfinals?
Before facing Zheng, Rybakina had not lost a set in four main-draw matches.
Her most emphatic performance came against Naomi Osaka.
Rybakina defeated the four-time Grand Slam champion 6-1, 6-4 in only 66 minutes, reaching the US Open quarterfinals for the first time.
The Sports Encounter analyzed that performance in Rybakina’s straight-sets victory over Osaka.
At the time, she was already only one victory away from No. 1.
Zheng ensured that final step was considerably more difficult than the previous four.
Why Was Zheng Qinwen Such a Dangerous Quarterfinal Opponent?
The ranking beside Zheng’s name did not accurately describe the player Rybakina was facing.
Zheng entered the tournament ranked No. 121 because an elbow injury and subsequent surgery had disrupted her previous season and early 2026 campaign.
She had been ranked as high as World No. 4.
She was also the 2024 Australian Open finalist and the Olympic singles gold medalist from Paris.
The injury forced her to qualify for the US Open.
Once she entered the main draw, the old level began to reappear.
The official US Open account of Zheng’s run described her as only the second qualifier to reach the women’s quarterfinals in New York, following Emma Raducanu in 2021.
That comparison carried obvious intrigue.
Raducanu went on to win the title.
Zheng’s run has ended one round earlier.
How Remarkable Was Zheng Qinwen’s US Open Run?
It was one of the strongest comeback stories of the tournament.
Zheng had to win through qualifying simply to enter the main draw.
She then survived increasingly difficult matches while spending more time on court than any other women’s quarterfinalist.
Before facing Rybakina, the official US Open quarterfinal breakdown listed Zheng at 9 hours and 29 minutes on court across her main-draw matches.
Three of those four matches went three sets.
Her final qualifying match had also gone the distance.
That workload matters when assessing the third set against Rybakina.
Zheng did not arrive at this quarterfinal fresh.
She arrived after seven matches in New York and repeated emotional recoveries.
Yet she still took the first set from a player who had not lost one all tournament.
How Did Zheng Beat Iga Swiatek Before Facing Rybakina?
Zheng’s Round-of-16 victory was arguably the result that transformed her run from encouraging comeback to genuine title threat.
Swiatek led 5-0 in the first set.
Zheng won seven consecutive games.
She then took the second set 6-3 to eliminate the six-time major champion.
The victory was especially notable because Swiatek had previously dominated their rivalry.
Our earlier US Open coverage of Swiatek’s historic Grand Slam consistency streak showed the scale of the opponent Zheng removed.
That upset changed expectations around the Chinese player’s tournament.
Rybakina finally stopped the momentum.
What Was the Rybakina vs Zheng Head-to-Head Before the US Open Quarterfinal?
Rybakina entered the match leading their career series 4-1.
The two had already met twice in 2026.
Rybakina won both.
She defeated Zheng in Doha after losing the opening set and also came back from a set down against her in Madrid.
The pattern became relevant again in New York.
| Meeting | Winner | Score |
|---|---|---|
| 2022 Wimbledon | Rybakina | 7-6(4), 7-5 |
| 2023 Beijing | Rybakina | 6-1, 6-2 |
| 2024 WTA Finals | Zheng | 7-6(4), 3-6, 6-1 |
| 2026 Doha | Rybakina | 4-6, 6-2, 7-5 |
| 2026 Madrid | Rybakina | 4-6, 6-4, 6-3 |
| 2026 US Open | Rybakina | 3-6, 6-1, 6-4 |
Rybakina now leads the rivalry 5-1.
More interestingly, three of her most recent victories over Zheng have required her to recover after losing the first set.
That suggests the matchup has become much closer than the raw 5-1 record implies.
What Changed After Zheng Won the First Set?
Rybakina’s biggest adjustment was the speed with which she reclaimed the initiative.
She is at her most dangerous when the first serve and first groundstroke allow her to dictate without becoming trapped in long neutral exchanges.
Zheng prevented that consistently in the opening set.
Rybakina began doing it to Zheng in the second.
The 6-1 score reflected a dramatic change in the balance of the rallies.
The Guardian’s live coverage described Rybakina as becoming increasingly aggressive from the baseline while her service games grew stronger as the match developed.
The result was a reset.
Zheng’s excellent first set no longer carried scoreboard value once the players entered the decider.
Did Rybakina Drop Her First Set of the 2026 US Open?
Yes.
Zheng became the first player to take a set from Rybakina at this year’s tournament.
Rybakina had reached the quarterfinals without dropping one.
That unbeaten run included her dominant victory over Osaka and made her one of only four active women to have reached the quarterfinals at all four Grand Slams without dropping a set at least once during her career.
The achievement had previously been matched by Venus Williams, Serena Williams and Sabalenka among active players at the time the tournament began.
What Does the Victory Mean for Rybakina’s Grand Slam Season?
Rybakina entered 2026 already established as a major champion because of her 2022 Wimbledon title.
Winning the Australian Open in January added a second major and changed the expectations around the rest of her season.
New York was the missing piece in terms of deep Grand Slam runs.
Before this year, she had never reached the US Open quarterfinals.
She has now gone one stage further.
A semifinal appearance means she has reached at least the last four of three different majors during her career and has now translated her hard-court strength into her deepest New York run.
Who Will Elena Rybakina Play in the US Open Semifinal?
Rybakina will face the winner of the quarterfinal between Coco Gauff and Mirra Andreeva.
That match follows the Rybakina-Zheng contest on Wednesday’s Arthur Ashe Stadium schedule.
Both potential opponents bring major-title credentials.
Gauff is a former US Open champion and arrived in the quarterfinals without dropping a set after defeating Iva Jovic 6-1, 6-4.
The Sports Encounter covered that result in our report on Gauff’s controlled fourth-round victory.
Andreeva reached her first US Open quarterfinal after fighting past Anastasia Potapova and entered the tournament as the reigning French Open champion.
Either matchup would present Rybakina with a significantly different tactical problem.
How Does Rybakina’s Semifinal Affect Aryna Sabalenka?
The ranking consequence is settled, but the title race is not.
Sabalenka survived an extraordinary quarterfinal against Wimbledon champion Linda Noskova, winning 7-6(1), 3-6, 7-6(7).
That kept alive her attempt to win a third consecutive US Open title.
The Sports Encounter had already tracked Sabalenka and Noskova’s route through the draw in our US Open quarterfinal race analysis.
Sabalenka now faces Jessica Pegula in one semifinal.
Rybakina will occupy the other.
The possibility of a Rybakina-Sabalenka final therefore remains alive even though the No. 1 ranking has already changed hands.
Why Could a Rybakina vs Sabalenka US Open Final Be So Significant?
It would bring together the outgoing World No. 1 and the woman replacing her.
Sabalenka would also be chasing a third consecutive US Open championship.
Rybakina would be chasing her third Grand Slam title and first in New York.
The rivalry already carries significant major-final history, including their meeting at the 2026 Australian Open.
There is still considerable tennis to play before that possibility becomes reality.
But after Wednesday’s result, it is no longer simply a ranking storyline.
It could become the final.
What Did the International Media Say About Rybakina vs Zheng?
The immediate international reaction focused on two connected themes: Rybakina’s resilience and Zheng’s inability to convert another brilliant start into one more extraordinary escape.
The Guardian’s live coverage emphasized how Rybakina recovered her serving rhythm and aggressive baseline game after losing the opening set.
Before the match, Reuters had framed the quarterfinal as Rybakina’s opportunity to complete her climb to No. 1 while warning that Zheng represented an unusually dangerous opponent because of her repeated comeback victories.
The official US Open had gone even further before play began.
Its Day 11 prediction called a three-set Rybakina victory.
That is exactly what happened.
The larger reaction around Zheng is unlikely to be defined purely by defeat.
A player ranked outside the Top 100 because of injury came through qualifying, eliminated seeded opponents and Grand Slam champions, and took the eventual new World No. 1 into a third set in a major quarterfinal.
That is a significant return to the elite level even without a semifinal appearance.
What Does Zheng Qinwen’s US Open Run Mean for the Rest of 2026?
The ranking beside Zheng’s name should rise considerably after this tournament.
More importantly, the tennis suggests the elbow problems that disrupted her previous year are no longer defining her level.
She has once again beaten a multiple Grand Slam champion.
She has once again reached the US Open quarterfinals.
She has demonstrated the physical and mental capacity to survive long matches and extended tournament workloads.
The next challenge is reducing the number of emergencies she has to survive.
The repeated 0-5 recoveries made her run extraordinary.
They also indicate how often she allowed matches to move dangerously close to being lost.
Against Rybakina, there was finally no way back.
How Does This Result Change the US Open Women’s Draw?
The semifinal picture now contains Rybakina, Sabalenka and Pegula, with Gauff and Andreeva contesting the final available place.
The women’s tournament has therefore retained many of its leading contenders deep into the second week.
That contrasts with a men’s draw that has already produced extraordinary disruption.
Ben Shelton eliminated defending champion Carlos Alcaraz in a five-set match that ended at 3:33 a.m., while Frances Tiafoe recovered from two sets down to reach another US Open semifinal.
The Sports Encounter has followed that broader tournament volatility throughout the fortnight, beginning with our US Open report on the early rain, upsets and major exits.
Our subsequent coverage of Osaka, Keys and the developing second-round drama showed how quickly the tournament was already beginning to change.
Rybakina has been one of the few leading contenders to move through that instability with sustained authority.

Final Verdict: Zheng Found Rybakina’s Limit, Then Rybakina Raised It
Zheng accomplished something nobody else had managed against Rybakina at this US Open.
She took a set from her.
For a while, she threatened to take the tournament away from her too.
Rybakina’s response explains why she is about to sit at the top of the women’s game.
She did not need the match to remain comfortable.
She needed to solve it.
After losing the opening set 6-3, she won the second 6-1 and survived the pressure of a decider against a player who had spent two weeks escaping situations that looked impossible.
Zheng’s latest escape never came.

And this time, when she leaves New York, the ranking beside her name will read No. 1.
