The 2026 Cincinnati Open women's singles draw has delivered a dramatic mix of tight matches, major upsets, and emerging contenders as the tournament moves toward its final stages.
Jessica Pegula booked her place in the semifinals after surviving a thrilling three-set battle against fellow American Amanda Anisimova, while Czech youngster Sára Bejlek produced one of the biggest upsets of the tournament by defeating world No. 1 Aryna Sabalenka.
Key Singles Results
Jessica Pegula Defeats Amanda Anisimova
Jessica Pegula defeated Amanda Anisimova 6-4, 2-6, 7-6(4) in a hard-fought quarterfinal.
Pegula appeared to have control of the match after taking the opening set, but Anisimova responded strongly in the second. The match ultimately went to a deciding-set tiebreak, where Pegula held her nerve to secure the victory.
The win sends Pegula into the Cincinnati semifinals, where she is scheduled to face Iga Swiatek.
Sára Bejlek Stuns Aryna Sabalenka
One of the tournament's biggest surprises came when Sára Bejlek defeated world No. 1 Aryna Sabalenka 7-6(7), 6-4.
Bejlek repeatedly recovered from difficult positions and showed impressive composure against one of the most powerful players in women's tennis. The victory was particularly significant because it marked Bejlek's first win over a Top-10 opponent and secured her first Cincinnati quarterfinal appearance.
Sabalenka's early departure also has implications for the WTA rankings, with Elena Rybakina having an opportunity to challenge for the No. 1 position.
Coco Gauff Advances
Coco Gauff defeated Marie Bouzkova to continue her Cincinnati campaign.
Gauff's ability to stay composed in important points remains one of the defining characteristics of her game. Her progress keeps another major American contender in the tournament and sets up a quarterfinal meeting with Marta Kostyuk.
Marta Kostyuk Battles Past Mirra Andreeva
Marta Kostyuk defeated Mirra Andreeva 4-6, 6-0, 6-2 in a dramatic comeback.
Andreeva took the opening set, but Kostyuk completely changed the momentum in the second set. She won it without dropping a game before continuing her aggressive play into the deciding set.
The victory puts Kostyuk into the Cincinnati quarterfinals against Gauff.
The Biggest Storylines
Sabalenka's Shock Exit
Sabalenka's loss to Bejlek is arguably the biggest headline of the tournament. The world No. 1 entered Cincinnati as one of the leading contenders, but her campaign ended earlier than expected.
The defeat is particularly notable because Cincinnati is an important hard-court event immediately before the U.S. Open. Sabalenka will now have to regroup quickly before the final Grand Slam of the season.
Pegula's Resilience
Pegula's victory over Anisimova demonstrated her ability to survive a high-pressure match.
After losing the second set, Pegula found a way through the deciding-set tiebreak. That kind of resilience can become particularly valuable during the late stages of a major tournament.
Bejlek Emerges as a Player to Watch
Bejlek's victory over Sabalenka has placed the young Czech player firmly in the spotlight.
Defeating a world No. 1 requires more than technical ability. Bejlek showed that she could compete under pressure, recover from difficult situations, and maintain her level against one of the biggest hitters on tour.
Cincinnati Open Semifinal Picture
Pegula has secured one semifinal position and will face Iga Swiatek.
The other side of the draw features the remaining quarterfinal contenders, including Bejlek and Madison Keys, while Gauff and Kostyuk are also scheduled to meet.
That leaves Cincinnati with an intriguing semifinal race featuring established stars alongside players making breakthrough runs.
What It Means Ahead of the U.S. Open
The Cincinnati Open is one of the final major opportunities for players to build confidence before the U.S. Open.
For Pegula, reaching the semifinals provides valuable momentum. For Bejlek, defeating Sabalenka could represent a career-changing breakthrough. Gauff and Kostyuk also have an opportunity to make a deep run and carry positive form into New York.
With the U.S. Open beginning on August 23, the Cincinnati results could provide an important indication of which players are entering the final Grand Slam of the season in the strongest form. The U.S. Open women's draw is already available through the official tournament site.
Final Takeaway
The Cincinnati Open women's tournament has already produced several compelling stories.
Jessica Pegula survived a three-set thriller. Sára Bejlek stunned world No. 1 Aryna Sabalenka. Coco Gauff continued her run, while Marta Kostyuk produced an impressive comeback against Mirra Andreeva.
With the semifinals approaching, Cincinnati remains wide open—and the performances here could have significant implications for the upcoming U.S. Open.
