Mirra Andreeva vs. Anastasia Potapova — US Open 2026 Fourth-Round Match Report
Mirra Andreeva has finally pushed beyond the barrier that had stopped her in New York every year.
But the moment came with an uncomfortable ending.
Andreeva recovered from a set down to beat Anastasia Potapova 5-7, 6-4, 6-3, reaching her first US Open quarterfinal after previous exits in the second round in 2023 and 2024 and the third round last year.
The final game should have belonged entirely to her breakthrough.
Instead, Potapova hurt her leg, needed a medical timeout and returned only to face the inevitable.
When Andreeva eventually completed the victory, she walked across to comfort her opponent.
A fine contest deserved a happier finish.

Andreeva Wins the Messy Numbers
Neither player produced a particularly clean statistical sheet.
Andreeva hit 23 winners and 48 unforced errors.
Potapova finished with 19 winners and 41 errors.
There were 14 double faults between them.
Andreeva committed eight.
Potapova six.
The difference came in the margins around those mistakes.
Andreeva won 99 of the 192 points, Potapova 93.
Her dominance ratio was 1.07 to 0.93, and she converted six of 10 break points compared with Potapova’s four of seven.
The most useful advantage came against the second serve.
Andreeva won 63 percent of second-serve return points.
Potapova won 62 percent.
That left both players constantly vulnerable once the first serve missed.
The match became less about serving authority and more about who could survive enough of the resulting pressure.
Andreeva did.
New York Finally Opens Up for Andreeva
The progression is now clear.
In 2023, Andreeva beat Olivia Gadecki before losing to Coco Gauff in the second round.
In 2024, she beat Camila Osorio before Ashlyn Krueger stopped her in the second round.
Last year, she went one stage further, beating Alycia Parks and Potapova before losing to Taylor Townsend in the third round.
This time she has gone through Janice Tjen, Eva Lys, Nikola Bartunkova and Potapova.
For the first time, she is into the US Open quarterfinals.
There is also an interesting echo in the Potapova result.
Andreeva beat her 6-1, 6-3 in New York last year.
This was nothing like that match.
Potapova pushed her through three sets and was still fighting deep into the decider before injury intervened.
Andreeva had to work considerably harder for the same name on the result sheet.
The Breakthrough Arrives With Mixed Emotions
For Andreeva, this is another step forward at a tournament where progress has come year by year rather than all at once.
Three rounds.
Now the quarterfinals.
That is the part she will remember.
The final image, though, belonged to two players rather than one.
Potapova limping through the closing stages.
Andreeva completing the win.
Then Andreeva crossing the court to comfort her.
A breakthrough for one.
A cruel ending for the other.
