BEIJING, China, October 9, 2026: Elise Mertens has knocked three Grand Slam champions out of the China Open in three consecutive rounds, and her latest victim was Iga Swiatek. The Belgian No. 13 seed beat the 2023 Beijing champion 7-6(0), 6-3 on Friday to reach her first WTA 1000 singles semifinal since 2021. Waiting on Saturday is China’s Zheng Qinwen, whose 6-3, 7-6(6) victory over Elina Svitolina completed a remarkable turnaround from a season interrupted by injury and a slide down the rankings.
These were the last two quarterfinals of the WTA 1000 event, and together they left just one top-eight seed standing: Mirra Andreeva. Mertens has found a way past three accomplished champions with very different games; Zheng has returned to the latter stages of major tournaments through aggressive tennis and repeated tests of nerve. Their semifinal will decide which approach gets a place in Sunday’s final. Across the draw, Andreeva faces 20-year-old Nikola Bartunkova, whose route has been every bit as disruptive to the original seeding.

How Did Elise Mertens Beat Swiatek After Removing Gauff?
Mertens arrived at Friday’s quarterfinal carrying an awkward head-to-head: she had lost both previous tour meetings with Swiatek. That history offered little protection to the Pole once the opening set reached a tiebreak. Mertens won all seven points in the breaker, then took the second set 6-3 to finish the match in one hour and 50 minutes.

How Did Elise Mertens Beat Swiatek After Removing Gauff?
Mertens arrived at Friday’s quarterfinal carrying an awkward head-to-head: she had lost both previous tour meetings with Swiatek. That history offered little protection to the Pole once the opening set reached a tiebreak. Mertens won all seven points in the breaker, then took the second set 6-3 to finish the match in one hour and 50 minutes.
What Does Swiatek’s Defeat Mean Beyond Beijing?
Swiatek had reached the quarterfinals with a particularly commanding 6-1, 6-3 win over Iva Jovic. Her Beijing elimination is therefore another reminder that a strong performance in one round does not necessarily transfer to an opponent who controls pressure points differently in the next.
How Has Zheng Qinwen Turned a Wild Card Into a Semifinal?
Zheng’s path explains why Saturday’s match cannot be judged on seed numbers alone. The former world No. 4 needed to qualify for the US Open after a difficult period involving an elbow injury and a major ranking decline. She then reached the New York quarterfinals, including an extraordinary recovery from 5-0 down in the first set to beat Swiatek in straight sets.
Mertens vs. Zheng: Which Player Has the Semifinal Edge?
They arrive with contrasting evidence. Mertens has beaten three major champions consecutively and has already shown she can reverse unfavorable head-to-head records. Zheng brings home support, heavier winner production and the confidence of a recent US Open run that included victories in difficult scoreboard situations.
The 7-0 tiebreak is the most revealing number in the score. A closely contested first set ended with Swiatek unable to win a point when the margins became smallest. Mertens then converted that advantage into a straight-sets victory rather than allowing the former champion another opportunity to reset the match.
Two days earlier, Mertens had beaten Coco Gauff 6-3, 6-3, overturning a 0-5 head-to-head record. Our China Open Round-of-16 analysis detailed how the Belgian repeatedly placed Gauff’s serve under pressure and denied her time to recover. That was a different match from the Swiatek quarterfinal, but the common thread is Mertens’ ability to make established favorites play uncomfortable, consequential points.
Her sequence began with Jelena Ostapenko. Ostapenko, Gauff and Swiatek are all Grand Slam singles champions; defeating those three in succession makes this the first tournament of Mertens’ career in which she has beaten three major champions. According to the WTA’s account of the Swiatek upset, she is also the first player since Aryna Sabalenka in 2018 to eliminate multiple former China Open champions in one edition.
The larger Beijing story has been building for days. First Elena Rybakina fell, then Aryna Sabalenka, as TSE reported when the top two seeds exited. Gauff’s loss removed the third seed. Swiatek’s departure has now completed another significant clearing of the draw, yet Mertens has earned her place by repeatedly taking on precisely the opponents expected to benefit from those earlier upsets.
What Does Swiatek’s Defeat Mean Beyond Beijing?
Swiatek had reached the quarterfinals with a particularly commanding 6-1, 6-3 win over Iva Jovic. Her Beijing elimination is therefore another reminder that a strong performance in one round does not necessarily transfer to an opponent who controls pressure points differently in the next.
It also changes the year-end championship picture. The WTA confirms that Swiatek’s loss secured singles qualification for Mirra Andreeva and Linda Noskova. Andreeva remains in Beijing’s title race; Noskova was eliminated earlier in the week but can now look toward her first appearance in the season-ending singles field. Swiatek’s enduring consistency, examined in TSE’s report on her remarkable Grand Slam progression streak, makes the ranking consequence especially noteworthy.
How Has Zheng Qinwen Turned a Wild Card Into a Semifinal?
Zheng’s path explains why Saturday’s match cannot be judged on seed numbers alone. The former world No. 4 needed to qualify for the US Open after a difficult period involving an elbow injury and a major ranking decline. She then reached the New York quarterfinals, including an extraordinary recovery from 5-0 down in the first set to beat Swiatek in straight sets.
Her quarterfinal defeat to eventual US Open champion Elena Rybakina stopped that run, but it also provided evidence that Zheng was again able to compete deep into elite events. TSE’s analysis of the Rybakina-Zheng quarterfinal traced the comeback and its significance for the world No. 1 race.
Beijing has supplied a different kind of proof. Entering on a wild card rather than a seeding, Zheng beat Svitolina in one hour and 47 minutes. She took the first set 6-3, then settled a tight second set in an 8-6 tiebreak, converting her second match point. The official match statistics credit Zheng with 36 winners to Svitolina’s 15. They also show 38 unforced errors from Zheng, compared with 13 from Svitolina.
That combination is essential to understanding her semifinal chances. Zheng’s willingness to attack produced far more outright winners, but it also carried a substantial error cost. She won 54 percent of the points against Svitolina, enough to earn the victory without suggesting every phase of the match was controlled. Her more aggressive patterns are capable of opening a match against an opponent as disciplined as Mertens; the question is whether she can sustain them when the Belgian keeps extending the contest.
The WTA’s post-match report puts Zheng’s wider surge at 12 victories in her last 13 tour matches. She is projected to move back into the Top 40 after having fallen to No. 160 in June. Beijing is now her fourth career WTA 1000 semifinal and third on Chinese soil. Her result also makes her the third wild-card semifinalist in the tournament’s history, following Peng Shuai in 2006 and Wang Qiang in 2018.
Mertens vs. Zheng: Which Player Has the Semifinal Edge?
They arrive with contrasting evidence. Mertens has beaten three major champions consecutively and has already shown she can reverse unfavorable head-to-head records. Zheng brings home support, heavier winner production and the confidence of a recent US Open run that included victories in difficult scoreboard situations.
Zheng won their only previous meeting, according to the WTA. That is useful context, although one match offers limited predictive value against a player performing at her current level. The semifinal’s central tactical question is more immediate: can Zheng’s first-strike tennis produce enough short points before Mertens turns rallies and critical service games into tests of patience?
There is no verified injury development from Friday’s two quarterfinals that warrants an additional medical storyline. The available evidence points instead to execution under pressure: Mertens took the first-set breaker 7-0 against Swiatek, while Zheng survived an 8-6 breaker against Svitolina. Those very different tiebreak wins created the matchup.
Andreeva vs. Bartunkova: The Other Semifinal Is a Generational Test
Mirra Andreeva, the No. 4 seed and reigning French Open champion, survived two tiebreaks to beat Ekaterina Alexandrova 7-6(4), 7-6(3) on Thursday. She had lost their previous two meetings, and Alexandrova recovered from 5-2 down in the second set to make Andreeva finish the job under pressure. The 19-year-old eventually did so in one hour and 53 minutes.
Nikola Bartunkova offered the opposite kind of scoreboard. The No. 26 seed swept aside Wimbledon runner-up Karolina Muchova 6-3, 6-0 in 67 minutes, winning the opening five and final seven games. She had already beaten Sabalenka and will contest her first WTA 1000 semifinal. The earlier TSE examination of Andreeva and Bartunkova’s routes captured how unusually open this half of the draw had become.
Andreeva beat Bartunkova 6-2, 7-6(5) at the US Open last month. That gives the French Open champion a recent reference point, though Bartunkova has since added wins over Sabalenka and Muchova. The wider strength of Czech tennis, explored in TSE’s Billie Jean King Cup final coverage, provides useful background to a new Czech player arriving at a major semifinal stage.

China OpenChina Open 2026: Muchova Survives Osaka, Andreeva Cruises, While Bartunkova Continues to Break ThroughWhat Should Tennis Fans Watch on October 10?
- Mertens’ return pressure: Can she create difficult second-serve points and extend the rallies that test Zheng’s attacking consistency?
- Zheng’s first-strike balance: Her 36 winners against Svitolina came alongside 38 unforced errors. How she manages that trade-off against Mertens may determine the match.
- Andreeva’s finishing: She let a substantial second-set advantage slip against Alexandrova before recovering in the tiebreak. Bartunkova is unlikely to make the semifinal comfortable.
- Bartunkova against a recent conqueror: The 20-year-old now faces the player who eliminated her at the US Open, with much more confidence and a first WTA 1000 final at stake.
For the first time this week, the title race is no longer about which highly seeded star might survive the upsets. The semifinal lineup is settled. One young Grand Slam champion, one surging Czech prospect, one returning Chinese favorite and one Belgian who has made a specialty of ending champions’ tournaments will determine Beijing’s two finalists.
