Aryna Sabalenka and Jessica Pegula Meet Again With the No. 1 Race Gone but the US Open Prize Bigger Than Ever

Aryna Sabalenka vs. Jessica Pegula — US Open 2026 Semifinal Preview

Aryna Sabalenka and Jessica Pegula know this stage, and they know each other.

The difference tonight is that one subplot has disappeared.

After Elena Rybakina’s victory over Qinwen Zheng, Sabalenka can no longer retain the World No. 1 ranking, while Pegula can no longer reach No. 1 by winning the title either.

That hardly makes this semifinal smaller.

For Sabalenka, there is another US Open title to chase.

For Pegula, there is something even more personal available: a first Grand Slam singles title.

And standing between them is a rivalry that has already produced a US Open final, a US Open semifinal and 13 completed meetings.

Sabalenka leads 9-4.

Pegula, though, won their most recent encounter.

Aryna Sabalenka vs. Jessica Pegula Head-to-Head Ahead of the US Open Semifinal

Sabalenka Owns the Rivalry, but Pegula Has Recently Found Cracks

The overall head-to-head favours Sabalenka heavily.

She has won nine of their 13 meetings, including all three of their previous Grand Slam encounters.

That run includes the 2024 US Open final, when Sabalenka won 7-5, 7-5, and last year’s semifinal, which she took 4-6, 6-3, 6-4.

There is no mystery about who has historically had the better of this matchup on the biggest stages.

But Pegula has supplied some recent evidence that the pattern is not fixed.

She beat Sabalenka in a three-set Wuhan semifinal last year and then defeated her again on grass in Berlin this June, 6-4, 6-7(4), 6-0.

Sabalenka answered with victory at the WTA Finals between those two losses.

So while 9-4 looks imposing, the more recent picture is less comfortable for the defending champion.

Pegula’s Best Route Is to Take Time Away

The broad tactical question is familiar.

Sabalenka wants to hit through Pegula.

Pegula wants to prevent her from doing so comfortably.

That means taking the ball early, redirecting pace and refusing to let Sabalenka settle behind the first heavy strike.

Pegula’s forehand became especially important in her quarterfinal against Emma Navarro.

She gradually accelerated more decisively from that wing and found winners in the hardest exchanges after Navarro had initially controlled the match.

She may need the same willingness tonight.

Passive resistance is unlikely to be enough.

The more Pegula can turn Sabalenka’s pace back on her quickly, the less time the world No. 1 has to establish the full power pattern she prefers.

Sabalenka Has Had the Easier Route Until Noskova

Sabalenka moved through her first four rounds without spending excessive time on court.

She beat Camila Osorio 6-2, 6-4, Polina Iatcenko 6-1, 6-1, Kamilla Rakhimova 6-3, 6-4 and Taylor Townsend 6-4, 6-3.

Then Linda Noskova changed the temperature.

Sabalenka needed 2 hours 22 minutes to survive that quarterfinal 7-6(1), 3-6, 7-6(7).

It was by far her most demanding match of the tournament. It even felt like a final.

Her total court time through five matches stands at approximately 7 hours 27 minutes.

That Noskova battle may matter in two ways.

It cost Sabalenka energy.

It also gave her the sort of pressure test she had not previously been forced to pass.

Pegula Has Already Had to Solve Two Three-Set Problems

Pegula’s road has been less straightforward.

She opened with a 6-3, 6-2 win over Elena-Gabriela Ruse and needed only 56 minutes to dismiss Sofia Kenin 6-3, 6-1.

Leylah Fernandez then forced her into a significant recovery.

Pegula lost the first set 1-6 before turning the match around, 6-4, 6-3.

Sorana Cirstea followed in the fourth round, with Pegula winning 6-3, 6-4.

Then came another comeback against Emma Navarro.

Navarro took the opening set, but Pegula gradually found her forehand and prevailed 3-6, 6-4, 6-3.

Pegula has therefore already twice proved capable of solving a match after falling behind.

Her total court time is roughly 8 hours 16 minutes, about 49 minutes more than Sabalenka.

The US Open Has Become Their Shared Stage

Few rivalries arrive at a semifinal with this much recent New York history.

In 2024, they met for the title.

Sabalenka won.

In 2025, they met one round earlier.

Sabalenka won again.

Now comes the 2026 semifinal.

That sequence gives Pegula an obvious challenge.

She does not simply need to beat Sabalenka.

She needs to beat her at the tournament where Sabalenka has repeatedly stopped her.

For Sabalenka, the psychology is almost reversed.

Flushing Meadows has become one of the places where she has been able to trust her game most under pressure.

Pegula has already seen that from the other side of the net twice.

The No. 1 Ranking Is Gone, but Sabalenka Still Has Plenty to Chase

Rybakina’s quarterfinal victory over Zheng settled the ranking question before this semifinal begins.

Sabalenka can win the US Open and still will not remain World No. 1.

That removes one prize.

It does not remove the larger competitive incentive.

Sabalenka is the defending champion and remains in position to add another US Open trophy to a record that has already made New York one of the defining tournaments of her career.

There may even be something liberating in the ranking race being finished.

There is no longer any calculation attached to the result.

Only the title remains.

For Pegula, the Prize Is Bigger Than No. 1

Pegula has lost the mathematical route to the top ranking for now.

The more important prize remains directly in front of her.

A first Grand Slam title would change the shape of her career in a way a temporary ranking position never could.

She has already reached a US Open final.

She knows what this stage feels like.

And she knows exactly who stopped her there.

That gives tonight’s semifinal a different edge from a normal meeting between familiar opponents.

Pegula is not chasing points.

She is chasing the one major achievement still missing from an otherwise established career at the top of the sport.

The Numbers Say Sabalenka, Recent History Says Look Again

The headline statistic is unavoidable:

Sabalenka leads the head-to-head 9-4.

She is also 3-0 against Pegula at Grand Slams.

That makes her the logical favourite.

But Pegula has won two of their last three meetings, including their most recent encounter in Berlin.

She has also arrived in the semifinal having repeatedly found solutions after difficult starts.

Sabalenka, meanwhile, has just survived her first true ordeal of the fortnight.

The rivalry history says Sabalenka.

The recent evidence says this may be considerably tighter.

One Familiar Opponent, Two Very Different Prizes

Sabalenka is trying to continue her hold over New York.

Pegula is trying to change what New York has meant in this rivalry.

The ranking race has already moved on without them.

That may actually sharpen the semifinal.

Sabalenka wants another US Open title.

Pegula wants her first Grand Slam.

After 13 previous meetings, there is very little left for either woman to discover about the other.

Now one of them has to find a way through anyway.
