US Open 2026 Women’s Semifinal Preview: Sabalenka and Pegula Renew a Fierce New York Rivalry
Aryna Sabalenka and Jessica Pegula will add another chapter to their increasingly familiar rivalry when they meet in the women’s semifinals of the 2026 US Open.
The matchup brings together the top two players in the upper half of the draw, with world No. 1 Sabalenka continuing her pursuit of a third consecutive US Open title and third-seeded Pegula attempting to reach the final in New York for the second time.
It is also a rematch of two recent Arthur Ashe Stadium showdowns. Sabalenka defeated Pegula in the 2024 US Open final before getting past the American again in the 2025 semifinals. Pegula now has another opportunity to reverse that history—this time with a place in Saturday’s championship match at stake.
Sabalenka Survives Her Toughest Test
Sabalenka’s title defence nearly ended in a dramatic quarterfinal against Wimbledon champion Linda Noskova.
Noskova repeatedly pressured the defending champion with her serve and fearless baseline hitting, but Sabalenka recovered from a break down in the deciding set and held her nerve in the final tiebreak. Her 7-6(1), 3-6, 7-6 victory was easily her most demanding match of the tournament.
The performance was not as clean as some of Sabalenka’s earlier victories, but it may have been more valuable. She was forced to compete through scoreboard pressure, absorb an opponent’s best tennis and find solutions when her usual power was not immediately deciding the match.
That is exactly the kind of experience she may need against Pegula.
Sabalenka has now reached the US Open semifinals for a sixth consecutive year. Few players are as comfortable with the speed, atmosphere and late-round intensity of Arthur Ashe Stadium. Her ability to produce first-strike tennis remains the defining feature of her game, but her improved patience and defensive movement have made her much more difficult to unsettle.
Pegula Finds a Way Past Navarro
Pegula also needed three sets to secure her semifinal place, overcoming Emma Navarro 3-6, 6-4, 6-3 in an all-American quarterfinal.
The third seed struggled early and was not always at her sharpest, particularly on serve. Instead of allowing the match to escape, however, Pegula simplified her approach, competed through the difficult periods and gradually took control of the baseline exchanges.
The victory gave Pegula her 50th win of the 2026 season and sent her into the US Open semifinals for the third consecutive year.
That consistency matters. Pegula is no longer arriving at this stage simply hoping to produce an upset. She has become a fixture near the top of the women’s game and has developed the belief that she belongs in the final weekend of major tournaments.
Her challenge is turning that consistency into a breakthrough victory against the tournament’s most accomplished hard-court player.
Sabalenka vs. Pegula: The Tactical Matchup
Sabalenka holds a 9-4 advantage in their head-to-head series, but the numbers do not make this a straightforward matchup.
Pegula defeated Sabalenka in the Berlin semifinals earlier this season, winning 6-4, 6-7(4), 6-0. Although that meeting came on grass, it reinforced an important point: Pegula can trouble Sabalenka when she absorbs the initial pace, keeps her groundstrokes compact and makes the world No. 1 play additional shots.
The opening four strokes of each rally will be critical in New York.
Sabalenka will look to dominate with her first serve and attack Pegula’s second delivery. When she establishes control early, she can prevent Pegula from settling into the balanced, rhythmic exchanges she prefers.
Pegula’s return position and depth will therefore be essential. She does not need to overpower Sabalenka. Her best chance is to take the ball early, redirect pace and make Sabalenka change direction while moving. Pegula is particularly effective at sending a hard crosscourt ball back behind an opponent or redirecting it down the line without an exaggerated swing.
Sabalenka must also remain disciplined. Pegula is one of the tour’s best at exposing impatient shot selection. If the defending champion begins forcing low-percentage winners from neutral positions, Pegula can steadily accumulate errors without appearing to take major risks.
Key to the Match: Pegula’s Second Serve
Pegula cannot afford to offer Sabalenka repeated looks at a vulnerable second serve.
Navarro broke Pegula several times in the quarterfinal, and Sabalenka will apply considerably more pressure with her return. The world No. 1 is capable of standing inside the baseline and immediately turning a second serve into an attacking opportunity.
Pegula does not necessarily need a high ace total, but she must protect her service games with placement and variety. Serving into Sabalenka’s body could be an effective way to limit the Belarusian’s full swing, while occasional serves out wide may open the court for Pegula’s first groundstroke.
If Pegula consistently begins points in defensive positions, the match could move quickly. If she holds comfortably and forces Sabalenka to feel scoreboard pressure, the dynamic changes.
Can Pegula Turn Defence Into Attack?
Pegula’s movement is sometimes overlooked because of the efficiency of her ball-striking. Against Sabalenka, she will need both.
Simply retrieving is unlikely to be enough. Pegula must defend with purpose, sending the ball deep through the middle when stretched and looking for the first opportunity to regain her position near the baseline.
She should also be willing to change the height and rhythm of the rallies. Sabalenka prefers a predictable ball that allows her to swing freely. A higher, slower shot followed by a flatter redirect can interrupt that timing and create hesitation.
Pegula’s objective will be to make Sabalenka play one more neutral ball than she wants to play.
What Sabalenka Must Do
For Sabalenka, the formula begins with controlled aggression.
She has the larger serve, the heavier groundstrokes and the ability to finish points from almost anywhere on the court. The danger comes when aggression becomes impatience.
Sabalenka should attack Pegula’s second serve, use her backhand down the line to prevent the American from camping in the backhand corner and remain prepared to win longer rallies. She does not have to finish every point immediately.
Her quarterfinal escape against Noskova showed that she can remain dangerous even when an opponent takes away her preferred patterns. That resilience, combined with her experience in the latter stages of the US Open, makes her extremely difficult to defeat.
Sabalenka vs. Pegula Prediction
Pegula has the timing, court position and counterpunching ability to make this a genuine contest. Her victory over Sabalenka in Berlin should also remove any sense that the matchup is beyond her control.
However, Sabalenka’s serve and return give her more ways to dictate the match. She has repeatedly delivered against Pegula on the North American hard courts, and her comfort under the lights at Arthur Ashe Stadium remains a significant advantage.
Pegula can extend the rallies and force Sabalenka into uncomfortable moments, but she will need to serve better than she did in the quarterfinal and maintain exceptional depth from the baseline.
Expect Pegula to push the defending champion, particularly if Sabalenka carries any physical or emotional fatigue from her battle with Noskova. Over the course of three sets, though, Sabalenka’s weight of shot and ability to attack the second serve should eventually separate them.
Prediction: Sabalenka to defeat Pegula in three sets.
