New York, United States: The US Open 2026 women’s doubles draw is down to four teams after a quarterfinal round that produced one American breakthrough, two controlled victories from established contenders, and another statement from the tournament’s top seeds.
Katerina Siniakova and Taylor Townsend continued their march toward the title with a 6-4, 6-2 victory over Cristina Bucsa and Nicole Melichar-Martinez. Elise Mertens and Diana Shnaider removed fourth seeds Hsieh Su-Wei and Jelena Ostapenko 7-5, 6-3, while Gabriela Dabrowski and Luisa Stefani defeated Zhang Shuai and Jiang Xinyu 6-3, 6-4.
The most striking storyline came from American wild cards Ashlyn Krueger and Robin Montgomery. They defeated ninth seeds Erin Routliffe and Aldila Sutjiadi 7-6(5), 6-3 to reach the semifinals, extending a run that has become one of the strongest doubles stories of the second week in New York.
The semifinal lineup is now complete. Siniakova and Townsend will face Mertens and Shnaider, while Krueger and Montgomery meet Dabrowski and Stefani for places in the final.

US Open 2026 Women’s Doubles Quarterfinal Results
| Winning Team | Defeated | Score | Key Takeaway |
|---|---|---|---|
| Katerina Siniakova / Taylor Townsend | Cristina Bucsa / Nicole Melichar-Martinez | 6-4, 6-2 | Top seeds controlled the second set and advanced without a decider |
| Elise Mertens / Diana Shnaider | Hsieh Su-Wei / Jelena Ostapenko | 7-5, 6-3 | No. 8 seeds removed the No. 4 seeds in straight sets |
| Gabriela Dabrowski / Luisa Stefani | Zhang Shuai / Jiang Xinyu | 6-3, 6-4 | No. 2 seeds advanced with another composed performance |
| Ashlyn Krueger / Robin Montgomery | Erin Routliffe / Aldila Sutjiadi | 7-6(5), 6-3 | American wild cards eliminated the ninth seeds |
Siniakova and Townsend Keep the Career Grand Slam Push Alive
Katerina Siniakova and Taylor Townsend entered the quarterfinals as the No. 1 seeds and with the opportunity to move closer to completing a career Grand Slam together.
The pressure has not slowed them down.
They defeated Bucsa and Melichar-Martinez 6-4, 6-2 at Louis Armstrong Stadium, continuing a tournament in which they have repeatedly found ways to take control without being dragged into long deciding sets.
The opening set remained competitive long enough to test their patience. Once Siniakova and Townsend established the break they needed, the second set became considerably more comfortable.
The 6-2 finish matters beyond the scoreline because semifinal week compresses recovery time. Avoiding a third set gives the top seeds a cleaner physical transition into their meeting with Mertens and Shnaider.
The pair had already reached the quarterfinals with three consecutive straight-sets victories, including a win over Storm Hunter and Desirae Krawczyk. The official US Open described their run as another step toward completing the full set of major women’s doubles titles as a partnership.
Mertens and Shnaider Remove Another Dangerous Team
Elise Mertens and Diana Shnaider produced one of the quarterfinal round’s most consequential results by defeating Hsieh Su-Wei and Jelena Ostapenko 7-5, 6-3.
The first set was the real test.
Hsieh remains one of the most instinctive doubles players in the sport, particularly around the net, while Ostapenko can change the tempo of a match with raw power from either side.
Mertens and Shnaider stayed composed long enough to take the opening set 7-5 and then carried that momentum into the second.
Their victory creates a high-level semifinal against Siniakova and Townsend, with four players capable of winning points through very different patterns.
Siniakova brings elite doubles instincts and court positioning. Townsend offers left-handed variation, aggressive returning and strong net coverage. Mertens is one of the most experienced doubles players still in the draw, while Shnaider gives the pairing additional power and baseline pressure.
Krueger and Montgomery Become the American Story of the Doubles Draw
Ashlyn Krueger and Robin Montgomery entered the tournament without the expectations attached to the seeded teams around them.
They are now one victory from the final.
The American wild cards defeated Erin Routliffe and Aldila Sutjiadi 7-6(5), 6-3, eliminating the ninth seeds and extending a partnership with deep roots.
Krueger and Montgomery previously won the 2021 US Open girls’ doubles title together, and the official tournament site noted before the quarterfinals that they had not played together regularly since 2023.
The reunion has worked immediately.
The first set against Routliffe and Sutjiadi was decided in a tiebreak, exactly the type of moment that can expose an inexperienced partnership.
Krueger and Montgomery instead won it 7-5 and then separated themselves in the second set.
The result leaves them as the only unseeded team in the semifinals.
Their success also adds another layer to a tournament already producing strong American stories. Coco Gauff reached the singles quarterfinals with a controlled victory over Iva Jovic, covered in The Sports Encounter’s Gauff vs Jovic analysis, while Jessica Pegula and Emma Navarro created an all-American singles quarterfinal after strong runs through the draw.
Dabrowski and Stefani Continue Their Quietly Efficient Run
Gabriela Dabrowski and Luisa Stefani have not needed the same drama as several other teams.
The No. 2 seeds defeated Zhang Shuai and Jiang Xinyu 6-3, 6-4 to secure their semifinal place.
The scoreline reflects a team operating with control rather than relying on rescue tennis.
Dabrowski’s doubles experience remains central to the partnership, while Stefani provides athleticism, quick reactions around the net and the ability to create pressure on return.
Their path through the tournament has already included a three-set fourth-round battle against Eri Hozumi and Andreja Klepac, so they have shown they can win both extended matches and cleaner straight-sets contests.
That adaptability will matter against Krueger and Montgomery.
US Open 2026 Women’s Doubles Semifinal Matchups
| Semifinal | Matchup | Main Storyline |
|---|---|---|
| SF 1 | Katerina Siniakova / Taylor Townsend vs Elise Mertens / Diana Shnaider | Top seeds face a dangerous eighth-seeded pairing with major doubles experience |
| SF 2 | Ashlyn Krueger / Robin Montgomery vs Gabriela Dabrowski / Luisa Stefani | American wild cards face the No. 2 seeds for a place in the final |
Siniakova-Townsend vs Mertens-Shnaider Could Decide the Tournament
The first semifinal contains enough experience and tactical variety to feel like a potential final.
Siniakova and Townsend are the top seeds and have looked increasingly comfortable as the tournament has progressed.
Mertens and Shnaider, however, have already shown they can remove a dangerous seeded team without losing a set.
The matchup may come down to the first two shots after serve.
Townsend’s returning can immediately force opposing servers into defensive positions. Siniakova is exceptionally comfortable moving forward and closing angles around the net.
Mertens and Shnaider will try to prevent the top seeds from controlling that territory.
If Shnaider can use her power to keep Townsend and Siniakova from moving forward freely, the eighth seeds can make the match much more uncomfortable.
Krueger and Montgomery Have Nothing to Lose Now
The second semifinal has a very different psychological profile.
Dabrowski and Stefani are the second seeds.
Krueger and Montgomery entered as wild cards.
That removes much of the conventional pressure from the American pair.
They have already exceeded seed-based expectations, already eliminated a top-10 seeded team and already shown they can handle a tiebreak under Grand Slam pressure.
The challenge changes against Dabrowski and Stefani because the No. 2 seeds are unlikely to be surprised by aggressive net play or a fast start.
The Americans therefore need to maintain their first-strike confidence without becoming impatient.
The Quarterfinals Continued a Strong Tournament for Doubles
The women’s doubles competition has developed alongside an increasingly dramatic singles tournament.
Jessica Pegula’s title push continues after she reached another deep stage in New York. The Sports Encounter previously examined how Pegula’s victory over Sorana Cirstea kept both her title and ranking ambitions alive.
Emma Navarro also reached the quarterfinals after finally solving Anna Kalinskaya, creating a matchup with Pegula that guaranteed another American semifinalist. That progression is detailed in our Navarro vs Kalinskaya report.
Elena Rybakina’s surge has also reshaped the women’s championship picture after her victory over Naomi Osaka sent her into the quarterfinals for the first time. Readers can revisit that performance in our Rybakina vs Osaka analysis.
The Wider Women’s Tournament Remains Loaded
The women’s singles and doubles competitions are now running in parallel with several elite players still carrying major ranking and title implications.
The singles World No. 1 race involving Aryna Sabalenka, Rybakina, Pegula and Gauff has added another dimension to the second week. The Sports Encounter broke down those scenarios in our US Open World No. 1 ranking analysis.
Our broader US Open quarterfinal race report also showed how the women’s draw has remained more concentrated around established contenders than the men’s side.
The doubles draw tells a similar story, but with one major exception.
Krueger and Montgomery have broken through the seeded hierarchy.
Cincinnati Form Has Carried Into New York
Several players in the remaining field also arrived in New York with useful doubles form from the summer hard-court swing.
The Sports Encounter’s Cincinnati doubles wrap tracked the partnerships and results that helped shape the US Open conversation, including the performances of several players who later featured prominently in New York.
That continuity matters because doubles partnerships often depend more heavily on communication, movement patterns and shared tactical understanding than individual ranking alone.
The teams still alive have now had enough matches together in New York for those patterns to become established.
Why the Semifinals Could Be Decided at the Net
Both semifinals feature teams comfortable moving forward.
That makes first volleys and reaction exchanges particularly important.
At this stage of a major, baseline power alone rarely decides an entire doubles match.
The best teams shorten points.
They protect the middle.
They force returns into uncomfortable lanes.
They punish second serves.
Townsend and Siniakova are particularly effective at turning neutral points into front-court pressure.
Dabrowski and Stefani also understand how to manage space and positioning over long stretches.
Krueger and Montgomery’s challenge will be maintaining aggression without giving experienced opponents easy passing targets.
American Doubles Momentum Is Growing
Krueger and Montgomery are not the only Americans producing significant doubles stories in New York.
Taylor Townsend remains one half of the No. 1 team and has another opportunity to win a major title on home soil.
That creates the possibility of an all-American presence in the final regardless of which semifinal route produces it.
Townsend and Montgomery also represent very different stages of American doubles development.
Townsend is established at the highest level.
Montgomery and Krueger are turning a junior partnership into a senior Grand Slam breakthrough.
That contrast is one of the most compelling elements remaining in the draw.
Official US Open Women’s Doubles Draw
The complete bracket and live tournament progression are available through the official US Open women’s doubles draw.
The tournament’s official Day 10 doubles report confirmed the semifinal progression of Siniakova and Townsend as well as Mertens and Shnaider.
The earlier official US Open doubles update also detailed the quarterfinal qualification of the leading seeds and the emergence of Krueger and Montgomery as the only unseeded team to reach the last eight.
The Sports Encounter Verdict
The women’s doubles quarterfinals produced a semifinal field with three seeded teams and one American wild-card partnership that has refused to behave like an outsider.
Siniakova and Townsend remain the team to beat.
Mertens and Shnaider have already demonstrated they can remove a dangerous seeded pairing in straight sets.
Dabrowski and Stefani continue to look stable and experienced.
Krueger and Montgomery bring the unpredictability.
The Americans have already won a junior US Open title together, spent years apart as a regular partnership and returned to New York to make a senior Grand Slam semifinal.
That gives the final four a useful balance between pedigree and possibility.
The quarterfinals told us which teams could handle pressure.
The semifinals will tell us which partnerships can impose themselves when there is no room left for an ordinary performance.
