Rybakina Needs Just Five Games to Reach Ningbo Quarterfinals, but Kawa Could Be Her Toughest Test Yet

NINGBO, China, October 22, 2026: World No. 1 Elena Rybakina reached the Ningbo Open quarterfinals on Thursday when Uzbekistan’s Polina Kudermetova retired injured while trailing 5-0 in the opening set. The defending champion, playing her first tournament since withdrawing from Wuhan because of a lingering lower-leg and foot problem, needed only five games to advance at the WTA 500 event. She will face Poland’s unseeded qualifier Katarzyna Kawa on Friday, October 23, after the world No. 128 stunned fifth seed Belinda Bencic 7-5, 6-2 in the biggest ranking upset of her career.

The circumstances have created an intriguing quarterfinal. Rybakina, who won the Australian Open and US Open this year before climbing to No. 1, has completed no full set in Ningbo after receiving a first-round bye. Kawa, meanwhile, has played 45 games across two completed main-draw matches and defeated an established top-20 opponent for the first time. The Kazakh’s superior ranking, powerful serve and defending-champion status make her the favorite, but Thursday’s abbreviated appearance offered only limited evidence of her ability to withstand an extended contest after recent injury problems.

Rybakina vs Kudermetova: Ningbo Match Ends at 5-0 After Medical Treatment

Rybakina made an emphatic start to her title defense, winning the opening five games against Kudermetova before the contest ended prematurely.

The Uzbek qualifier was struggling physically and requested assistance from the physiotherapist when she trailed 3-0.

Kudermetova attempted to continue, but the difficulties persisted. With the score at 5-0, she retired without completing the opening set.

The match ended after approximately 33 minutes, leaving Rybakina through to the last eight but denying both players the opportunity to contest a complete set.

Kudermetova was visibly emotional as she left the court, and Rybakina offered support following the retirement.

The Kazakh also expressed sympathy for her opponent afterward, acknowledging the difficult playing conditions and the physical demands of previous matches. She noted that the balls were heavy and wished Kudermetova a quick recovery.

No definitive medical diagnosis for Kudermetova’s problem was established in the reports available on October 22. Describing the incident as an injury retirement is justified, but assigning a specific injury or recovery period would be speculative.

For Rybakina, the result secured a place in the quarterfinals without requiring the physical effort normally associated with a completed second-round contest.

Whether that limited court time will prove beneficial or leave her short of competitive rhythm is one of the interesting questions ahead of Friday’s match.

Elena Rybakina vs Polina Kudermetova: Match Summary

The retirement leaves an important distinction in Rybakina’s return.

She has officially recorded a victory and advanced in the draw. However, the match did not provide the sustained physical or tactical test of a completed encounter.

That distinction matters given her recent injury history and the demanding schedule still ahead.

Why Rybakina’s Return to Ningbo Carries More Uncertainty Than Her Ranking Suggests

Rybakina’s 2026 season has brought some of the greatest achievements of her career, but also recurring interruptions.

She won the Australian Open and later captured the US Open, establishing herself as the leading player in women’s tennis.

Her New York success also completed a remarkable rise to the top of the rankings.

The Sports Encounter’s report on Rybakina’s US Open final victory over Aryna Sabalenka examined the performance that confirmed her remarkable season.

Yet her route between those major victories was complicated by injury.

In August, she was forced to retire during her Cincinnati quarterfinal against Iga Swiatek after suffering a left ankle injury.

The problem initially threatened her US Open preparations, although she recovered sufficiently to compete and ultimately win the title in New York.

The Sports Encounter documented those early concerns in its Cincinnati report on Rybakina’s injury and the reshaped women’s draw.

Her fitness troubles resurfaced during the Asian swing.

Rybakina suffered a surprise three-set defeat to Alina Charaeva at the China Open on October 3 before withdrawing from the following Wuhan Open because of the continuing physical problem.

She subsequently returned to Ningbo, where she had enjoyed success in 2025.

According to the WTA’s October 4 injury update, the Kazakh had been managing a lingering lower-leg and foot problem that affected her tournament schedule.

The Sports Encounter also examined the consequences of Rybakina’s early Beijing departure and the elimination of the tournament’s top two seeds.

Rybakina’s Road From Injury to the Ningbo Quarterfinals

The timeline illustrates an unusual combination of success and physical uncertainty.

Rybakina has won two Grand Slam titles in 2026, yet the injuries surrounding those achievements have repeatedly affected her participation elsewhere.

Her ascent to world No. 1 was documented separately in The Sports Encounter’s coverage of Kazakhstan’s historic ranking milestone.

Ningbo offers a chance to restore competitive momentum before the WTA Finals. But reaching the quarterfinals through a retirement does not resolve every question about her current physical condition.

Katarzyna Kawa Stuns Belinda Bencic to Earn a Shot at World No. 1

While Rybakina progressed through an abbreviated match, Kawa produced one of the strongest performances of her career.

The 33-year-old Polish qualifier defeated fifth seed Belinda Bencic 7-5, 6-2, claiming her first victory against a player ranked inside the world’s top 20.

Bencic entered the contest ranked No. 14 and carried the experience of an Olympic singles gold medal and multiple deep runs at major tournaments.

Kawa, ranked No. 128, had already battled through qualifying and survived a demanding first-round encounter against Daria Snigur.

She began strongly against Bencic, racing into a 3-0 lead in the opening set.

The Swiss player recovered to level at 3-3, but Kawa broke again and served for the set at 5-3.

Bencic responded by breaking back, forcing the Polish player to recover from a missed opportunity.

Kawa held her nerve in the twelfth game, converting her fifth set point to take the opener 7-5.

The second set was more convincing.

Kawa broke for a 3-1 advantage and maintained control to complete a 6-2 victory.

Polish tennis reporting credited her with 31 winners, a significant attacking contribution against a far more established opponent.

It was the most important result of Kawa’s week so far and one of the strongest victories of her singles career.

The outcome also prevents Rybakina from facing Bencic, who had been positioned as a possible seeded quarterfinal opponent.

How Kawa Reached the Ningbo Quarterfinals

Kawa’s progress has been considerably more demanding than that of the defending champion.

The Polish player came through the qualifying competition, then recovered from losing the opening set against Snigur in the main draw.

She followed that performance with the straight-sets upset against Bencic.

Katarzyna Kawa’s Ningbo 2026 Main-Draw Results

Kawa’s victory against Bencic was not simply a case of a favored player losing form.

The Pole took the initiative in both sets, recovered from surrendering an early advantage and produced an attacking performance that created genuine pressure on the Swiss player.

That matters when assessing her prospects against Rybakina.

Although the ranking difference is substantial, Kawa arrives having completed two difficult matches and proved that she can respond to both physical and scoreboard pressure.

Five Games Against 45: The Extraordinary Contrast Before the Quarterfinal

The routes taken by Rybakina and Kawa offer a revealing statistical comparison.

Rybakina received a first-round bye as a top-four seed. Her second-round match then ended with only five games completed.

Kawa, by contrast, played three sets against Snigur and two more against Bencic.

Her two completed main-draw matches contained 45 games.

That is nine times the number of games contested during Rybakina’s Ningbo appearance.

Rybakina vs Kawa: Main-Draw Workload Before the Quarterfinal

TSE calculation: Kawa played 25 games against Snigur (1-6, 6-2, 6-4) and 20 against Bencic (7-5, 6-2), for a total of 45. She won 12 games against Snigur and 13 against Bencic, totaling 25 games won, and lost 20. Rybakina contested five games before Kudermetova retired. Qualifying games are excluded because a complete, consistently verified qualifying-game total was not established.

This comparison highlights the different demands facing the two players.

Kawa has enjoyed substantially more competitive court time, which could help her timing and confidence.

Rybakina has been spared a lengthy contest, potentially conserving energy after her injury layoff.

Neither advantage should be overstated.

More court time can improve rhythm but also increase fatigue. Less court time can aid recovery but leave a returning player without enough extended exchanges to assess physical readiness.

Friday’s meeting should provide a clearer indication of which factor matters more.

What Could Decide Rybakina vs Kawa?

Rybakina’s greatest advantage remains the quality of her first-strike tennis.

Her serve and aggressive baseline game allow her to shorten points, seize control early in rallies and put pressure on opponents’ service games.

Those qualities have been central to her rise to world No. 1.

Against a lower-ranked opponent, Rybakina would normally be expected to dictate play, particularly when landing a high percentage of first serves.

But Kawa’s performance against Bencic suggests she is capable of taking the initiative rather than merely defending.

The Pole’s ability to recover after losing momentum in the opening set was particularly important.

Against Rybakina, Kawa may need to prevent the world No. 1 from controlling too many points immediately after the serve.

That would require effective returns, careful court positioning and enough depth to stop Rybakina from repeatedly attacking short balls.

Kawa could also attempt to extend rallies and test the physical movement of an opponent returning from injury.

However, those are tactical possibilities rather than evidence of a confirmed vulnerability in Rybakina’s current movement. Thursday’s shortened match offered too little play to establish how well she can move through a demanding three-set contest.

For Rybakina, the essential task will be to reestablish serving rhythm and maintain her preferred attacking patterns without allowing Kawa’s confidence to grow.

For Kawa, the key may be surviving the opening exchanges and forcing the contest into situations where her recent competitive rhythm becomes useful.

Why Ningbo Matters Beyond One Quarterfinal

Rybakina’s return to Ningbo carries an important connection to her 2025 season.

Last year, she entered the tournament ranked ninth in the world and still chasing a place at the WTA Finals.

She won the title by defeating Ekaterina Alexandrova 3-6, 6-0, 6-2 in the championship match.

That victory helped propel her toward qualification for the season-ending event, which she also won.

According to the WTA’s official Ningbo tournament guide, Rybakina’s title run was the beginning of an 11-match winning streak to close the 2025 season.

Twelve months later, she returned as a three-time Grand Slam champion and the world’s top-ranked woman.

Her ranking and season-ending championship qualification are already secure, so Ningbo does not carry the same qualification pressure for her as it did in 2025.

Instead, the tournament offers an opportunity to restore momentum, defend 500 ranking points from last year’s title and gain confidence ahead of the WTA Finals.

That context becomes especially important following her injury interruptions.

The WTA’s official analysis of the Ningbo draw identifies Rybakina as already qualified for the Finals while several other contenders were still chasing the remaining places.

The Sports Encounter has been following that qualification picture through its analysis of Jessica Pegula, Coco Gauff and the late-season WTA Finals race.

Injuries Are Reshaping the Women’s Asian Swing

Rybakina’s interrupted schedule is not the only injury-related story affecting the closing stages of the season.

Iga Swiatek’s withdrawal from Ningbo followed her own physical setbacks and effectively ended her hopes of continuing the 2026 season.

The Sports Encounter’s report on Swiatek’s Ningbo withdrawal and the consequences for the WTA Finals race examines the wider implications.

Other players have also experienced injury-related withdrawals and retirements during the Asian swing, changing draw projections and creating unexpected opportunities.

That broader context makes Kudermetova’s retirement particularly unfortunate.

She had worked through qualifying and defeated Cristina Bucsa to reach the second round against the world’s top-ranked player.

The result gave Rybakina passage into the quarterfinals, but it also ended Kudermetova’s campaign before she could meaningfully test herself against the defending champion.

Rybakina’s sympathetic response reflected the difficult position of a player advancing because an opponent could not continue.

BNB Ningbo Open 2026: Women’s Singles Quarterfinals

The quarterfinals are scheduled for Friday, October 23, followed by the semifinals on Saturday and final on Sunday.

The tournament is played on outdoor hard courts and offers 500 ranking points to its singles champion.

The published prize-money schedule lists $33,475 for a singles quarterfinalist, $66,003 for a semifinalist, $114,500 for the finalist and $185,500 for the champion.

These figures are tournament prize allocations, not an assessment of the players’ total earnings or any personal financial circumstances.

What Would Another Ningbo Title Mean for Rybakina?

A successful title defense would give Rybakina a valuable result before the WTA Finals and strengthen the momentum she has struggled to maintain since the US Open.

It would also demonstrate that she can return to tournament competition and win multiple matches across successive days after her recent injury-related absences.

But the outcome remains uncertain.

Her current ranking and Grand Slam achievements establish her as the leading player in the draw, not as an inevitable champion.

Kawa has already shown the ability to defeat a more highly ranked opponent, while Jovic, Shnaider, Alexandrova and other quarterfinalists provide further challenges.

The more immediate question is whether Rybakina can complete a full match against a confident, physically prepared opponent.

If she does, the performance will provide a clearer measure of her competitive condition than Thursday’s shortened encounter.

Rybakina Has Reached the Last Eight, but Her Real Return Begins Against Kawa

Rybakina accomplished her immediate objective in Ningbo, advancing to the quarterfinals of a tournament she won twelve months earlier.

Yet the result came in circumstances that offered little clarity about her physical readiness.

Five completed games were enough to secure a place in the last eight because Kudermetova could not continue.

Kawa earned the same destination through a considerably tougher route, recovering from a set down against Snigur and then producing the biggest ranking upset of her career against Bencic.

The quarterfinal therefore presents an unusual contest between two players arriving with very different workloads.

Rybakina possesses the ranking, major titles and attacking weapons that make her the favorite. Kawa brings confidence, recent match practice and evidence that she can challenge opponents far above her in the rankings.

For the world No. 1, the important test is no longer simply reaching another quarterfinal.

It is demonstrating that her game and physical condition are ready to withstand the demands of a complete match, followed potentially by two more rounds in consecutive days.

For Kawa, Friday offers the biggest opportunity of an already remarkable week.

And for Ningbo, a quarterfinal that originally appeared likely to feature two established stars has become something potentially more intriguing: the defending champion seeking reassurance after injury against a qualifier playing some of the best tennis of her career.
