Four Seeds, Two Blockbusters: Sabalenka-Pegula and Rybakina-Gauff Own the US Open Semifinals
GOATIFYThe 2026 US Open women’s draw has reached a semifinal lineup that feels both orderly and explosive. The four highest seeds are still standing, but there is very little predictable about the two matchups they have produced.
Aryna Sabalenka meets Jessica Pegula in another New York collision after Sabalenka beat the American in the 2024 final and again in last year’s semifinal. On the other side, Elena Rybakina arrives on the verge of officially becoming world No. 1 and faces Coco Gauff, who has carried an 11-match winning streak into the final four.
The names are familiar, the stakes are enormous and the routes here have been different. Sabalenka had to survive Linda Noskova in three sets. Pegula recovered from a slow start against Emma Navarro. Gauff had to dig herself out of trouble against Mirra Andreeva. Rybakina has looked the cleanest of the four, dropping only one set during her run.
That leaves two very different questions for Thursday: can Pegula finally flip her US Open history against Sabalenka, and can Gauff turn Rybakina’s first-strike power into the longer, more physical contest that favors her game?
Sabalenka-Pegula is no longer just a rematch — it is a pressure test
Sabalenka enters with the most obvious historical target. She is two wins from a third consecutive US Open title, a level of New York dominance that would place her in rare company. Her path has not been effortless, though. Noskova pushed her into a deciding set and forced the defending champion to solve a match in which clean power alone was not enough.
That kind of escape can be useful at this stage of a major. Sabalenka has already had the night where the rhythm broke down, the opponent refused to leave and the match had to be won under scoreboard pressure. She knows she can survive that version of the tournament.
Pegula presents a different challenge because there is far more history between them. Sabalenka beat her for the 2024 US Open title and again in the 2025 semifinal, so Pegula is not walking onto court wondering what the matchup feels like. She knows exactly where the danger comes from: Sabalenka’s ability to seize the first short ball, drive through the middle of the court and turn a neutral rally into defense in one swing.
Pegula’s best route is to make the opening stages less comfortable than they have been in some of their New York meetings. Her first serve has to land early, and she cannot donate clusters of errors while Sabalenka is still settling. Pegula is at her best when she takes the ball early, redirects pace and keeps an opponent from loading repeatedly from the same position.
There is reason to believe the matchup can be closer than the recent US Open history suggests. Pegula has beaten Sabalenka in two of their last three meetings overall, and she has enough baseline stability to punish stretches when Sabalenka presses for too much. The American does not need to overpower the defending champion. She needs to prevent Sabalenka from dictating every important exchange.
The mental balance is fascinating. Sabalenka owns the recent New York results, but she also carries the burden of a three-peat chase. Pegula has the scar tissue of those losses, but also the freedom of knowing the expected outcome belongs to the other side of the net. If she can keep the match level deep into each set, the pressure can shift quickly.
Rybakina-Gauff is a fight over who gets to define the rallies
Rybakina’s semifinal has a different shape. She is about to become the new world No. 1, has lost only one set in the tournament and is trying to add the US Open to the Australian Open title she won earlier this year. Her game has looked built for hard courts because so many points begin on her terms.
The serve is the foundation. When Rybakina lands enough first serves, opponents can spend entire return games trying to reach neutral rather than actually creating pressure. Her flat groundstrokes then make the next ball just as difficult. That is why Gauff’s start matters so much. She cannot afford the type of opening set she had against Andreeva and assume there will always be enough time to recover.
Gauff’s quarterfinal comeback did, however, reinforce why she is dangerous even when the tennis is imperfect. She saved match points, extended rallies, defended with elite speed and gradually made Andreeva play more balls under stress. That resilience has become a defining part of her run. She has won 11 straight matches dating back to Cincinnati and has dropped only one set during that stretch.
Against Rybakina, defense alone will not be enough. Gauff has to make returns with depth, protect her own second serve and create enough long exchanges that Rybakina is forced to hit one extra attacking ball repeatedly. The longer the rallies become, the more Gauff can use her movement and physicality to change the match from a serving contest into a test of tolerance.
Rybakina will try to prevent that transformation. If she controls the first four shots of the rally, Gauff may never get the chance to impose the athletic advantage that makes her so difficult to finish against. This is why the matchup is so compelling: one player wants clean, short, high-quality first-strike tennis; the other wants enough resistance to make every point feel less clean.
The ranking milestone adds another layer for Rybakina. Becoming No. 1 next week is already secured, but arriving there with a second hard-court major in the same season would turn the ranking change into a championship statement rather than a statistical milestone. Gauff, meanwhile, has the chance to turn a home semifinal into another deep New York run and deny the player who has looked most efficient throughout the tournament.
The semifinal bracket has the star power of a final weekend and almost no easy tactical answer. Sabalenka has the championship history. Pegula has the familiarity and recent head-to-head evidence that she can beat her. Rybakina has been the cleanest player in the draw. Gauff has the defensive range and competitive stubbornness to make clean tennis disappear.
That is why the top four seeds surviving does not make this stage feel predictable. It gives the tournament four fully credible champions and two matches in which the first few games could determine what kind of contest everyone has to play.
