Elena Rybakina vs. Coco Gauff — US Open 2026 Semifinal Match Report
For a long time, Elena Rybakina could not quite solve Coco Gauff’s serve.
So she did something unexpected.
She slowed down.
Gauff had come out firing, particularly behind a second serve whose placement repeatedly wrong-footed the new World No. 1. She took the opening set 6-3 and for stretches looked capable of turning Arthur Ashe Stadium into precisely the kind of home-court advantage Rybakina would have feared.
Rybakina changed the rhythm rather than trying to overpower it.
Taking pace off the ball helped her find the break she needed in the second set. Then her own serving became increasingly secure, allowing her to play the deciding set from slightly in front.
Even when Gauff produced one last extraordinary escape by breaking Rybakina as she served for the match, the Kazakh did not lose her nerve.
She broke immediately back.
3-6, 6-4, 6-4.
For the first time in her career, Elena Rybakina is into the US Open final.
Gauff Comes Out Firing
The first set belonged to Gauff.
Both women held through the opening four games before Gauff began applying greater pressure.
At 3-2, she finally broke.
Then she consolidated for 5-2.
Rybakina held once more, but Gauff served out the set without allowing the momentum to wander.
6-3.
The American’s serving was particularly impressive because the danger was not confined to the first delivery.
Her second serve carried real speed and, more importantly, uncertainty.
The placement kept changing.
Rybakina could not consistently anticipate where it was going and struggled to establish the aggressive return position she normally wants.
Across the match, Gauff won 64 percent of her second-serve points.
Her average second serve was 93 mph (150 km/h) — actually faster than Rybakina’s 89 mph (143 km/h).
For a significant part of the semifinal, that second delivery was one of Gauff’s best weapons.

Rybakina Finds an Unlikely Answer
Rybakina started the second set by holding and then finally created some separation at 2-1.
She broke Gauff for 3-1 and consolidated for 4-1.
Gauff was not finished.
After Rybakina moved ahead 4-1, the American held for 4-2 and then recovered the break.
4-3.
A hold brought her all the way back to 4-4.
The stadium was alive again.
But Rybakina did not allow the comeback to become a reversal.
She held for 5-4, forcing Gauff to serve to stay in the set.
This time the pressure told.
Rybakina broke courtesy of a sudden and significant tactical change.
The interesting part was how she got there.
Rather than continually trying to meet Gauff’s pace with more pace, Rybakina began taking speed off some of the exchanges.
The resemblance to Mirra Andreeva’s tactics against Gauff in the quarterfinal was difficult to miss.
Andreeva had slowed rallies dramatically in the second-set tiebreak, effectively waiting for Gauff to provide the error.
Against her, the tactic eventually backfired.
For Rybakina, it worked.
The change disrupted Gauff’s rhythm enough to create the opening.
It was one of the stranger tactical turns of the match: one of the most powerful ball-strikers in women’s tennis finding her way back by hitting less aggressively.
6-4.
One set all.
She had spent much of the match struggling to find a reliable answer to Gauff’s serving patterns, yet somehow she had manufactured exactly the two return games she needed.
Set 2 at a Glance
- Rybakina saved 50% of break points faced (1 of 2) while converting 100% of her own (2 of 2), a dominant break-point split.

Serving First Gives Rybakina a Small but Useful Edge
The deciding set initially settled into a sequence of holds.
Rybakina 1-0.
Gauff 1-1.
Rybakina 2-1.
Gauff 2-2.
Neither player gave much away.
The same pattern continued through 3-3.
But Rybakina had one small structural advantage: she was serving first.
By this point, her own service games were also becoming easier.
She held for 4-3 and again made Gauff play from behind on the scoreboard.
Then came the breakthrough.
At 4-3, Rybakina broke.
5-3.
Suddenly, the woman who had spent the opening set being unsettled by Gauff’s serving was serving for a place in her first US Open final.
And she looked completely in the zone.
Gauff Produces One Last Miracle
What happened next was arguably Gauff’s finest moment of the match.
Rybakina appeared to have complete control.
The points were flowing in her direction.
The finish looked close.
Gauff broke her anyway by being super aggressive on return. And it worked.
5-4.
Against an opponent playing with that much conviction, at that stage of a Grand Slam semifinal, finding the tennis to break back required something special.
Arthur Ashe erupted.
For a few moments, it seemed possible that Gauff had found another escape, just as she had when saving two match points against Andreeva in the quarterfinal.
But this time Rybakina did not retreat after the setback.
She raised her level again.
Rybakina Breaks Back to Finish It
Gauff served at 4-5 with the stadium pushing her through every point.
Rybakina simply kept coming.
She created two match points on Coco’s serve.
And Gauff imploded.
She smashed an overhead out.
6-4.
Match.
It was a remarkably composed response to having failed to serve out the semifinal only minutes earlier.
Rather than carrying that disappointment into the next game, Rybakina immediately returned to the level that had put her in position to finish the match in the first place.
Staying in the zone may have been the most impressive part of the victory.
Set 3 at a Glance
- Rybakina won 87% of her first-serve points (13 of 15), the strongest number on the page.

Rybakina Wins the First-Serve Battle
The final numbers show why Rybakina was ultimately able to withstand Gauff’s pressure.
She won 76 percent of her first-serve points, compared with Gauff’s 58 percent.
Her average first serve reached 111 mph (178 km/h), with Gauff averaging 106 mph (171 km/h).
Rybakina also produced five aces and only two double faults.
Gauff finished with four aces and four double faults.
There was little between them in outright attacking production: Rybakina hit 22 winners, Gauff 20.
Both also produced plenty of errors — 39 from Rybakina and 32 from Gauff — reflecting how demanding the exchanges became.
But Rybakina held the broader advantage.
Her dominance ratio was 1.20, compared with Gauff’s 0.84, and she finished with an 88-82 edge in total points.
Six points separated them after 170 had been played.
Gauff Has Little Reason to Leave New York Discouraged
The defeat will hurt Gauff.
It was a home Grand Slam semifinal, played in front of a stadium willing her toward another final.
But there was plenty here to encourage her.
Her backhand remained outstanding for long stretches.
The second serve, often an area where uncertainty can creep into her game, was at times one of the most impressive shots on the court.
When her level dipped, the vulnerabilities returned mainly through the serve and forehand.
Those are not insignificant areas, but neither are they fixed limits on what her game can still become more.
She had also been dealing with a cold during the tournament, and after the physical and emotional demands of surviving Andreeva in the quarterfinal, it is reasonable to wonder how much energy remained when Rybakina made that final push.
Gauff gave everything she had.
This time, it was not quite enough.
Arthur Ashe Empties, but Rybakina Deserved Better
The contrast after match point was striking.
Within minutes of Gauff’s defeat, much of Arthur Ashe Stadium had emptied.
By the time Rybakina finished her on-court interview, signed the balls and prepared to hit them into the stands, there were comparatively few people left to receive them.
It was an unfortunate ending to an excellent semifinal.
The crowd had every right to throw its support behind Gauff. She was the American hope, playing at home, and that support helped carry her through several difficult moments.
But a Grand Slam semifinal is also bigger than one player.
Rybakina had just beaten an inspired Gauff, resisted the weight of a fiercely partisan stadium and recovered immediately after failing to serve out the match.
That deserved recognition too.
No. 1 Seed Against No. 2 Seed for the Title
All four leading seeds reached the US Open semifinals.
Now the bracket has produced the final that seeding predicted from the beginning:
No. 1 seed Aryna Sabalenka against No. 2 seed Elena Rybakina.
For Rybakina, there is another distinction.
She entered New York chasing the World No. 1 ranking.
She has already secured that.
Now she has reached a place she never had before.
A US Open final.
Gauff threw almost everything at her: the explosive start, the unpredictable serving, the backhand, the crowd and finally that last-minute break when Rybakina appeared ready to finish.
Rybakina absorbed all of it.
She even changed the nature of her own game when power alone was not solving the problem.
Then, after one final wobble, she found another level.
Arthur Ashe wanted Coco Gauff. Elena Rybakina earned the final anyway.
