For most of the third set, it looked like Madison Keys had done enough. She was one point from the fourth round, the crowd could sense the finish line, and Zheng Qinwen was still trying to find a way back into a match that had begun to tilt away from her. Then the script flipped. Zheng saved a match point, recovered from 5-1 down in the deciding set and somehow turned a near-exit into one of the more striking comebacks of the US Open 2026.
The final line read 6-1, 6-7 (3-7), 7-5, but that barely captures how much momentum Keys had before the end. Zheng had started fast, Keys fought back to level the match, and the third set became a test of nerve more than form. In that phase, Zheng was the steadier player when it mattered most, and that is why the upset landed the way it did.
The numbers tell the story of a match that was never settled for long. Zheng eventually closed it out 7-5 in the third after trailing 5-1, a run that reflected both resilience and a refusal to let one lost stretch define the whole night. Keys, the No. 22 seed, came within a point of advancing, but could not finish the job once Zheng found her footing.
What the result says about Zheng
This was more than a single comeback. Zheng Qinwen is still working back from elbow surgery and entered the event ranked outside the top 100, which makes the scale of this win hard to ignore. She was not supposed to be the player surviving the most difficult passages of the match, yet that is exactly what happened. The comeback did not arrive all at once either. Zheng said, “Never give up, stay there,” and added that “somehow little by little it just happened.” That fits the way the match unfolded: not with one dramatic swing, but with repeated small reversals until the balance changed.
That matters in a tournament like this because a player coming off injury and outside the top 100 is often treated as a short-term threat, not a real force. Zheng’s response suggested something more complicated. Even if the rhythm was uneven, she found enough against a seeded opponent to survive a match point and take the match away from Keys at the end. That is a meaningful result in any round, but especially on a day when the draw was already producing surprises.
A day that kept shifting
Zheng’s win was part of a busy Saturday at the 2026 US Open. Anastasia Potapova defeated Amanda Anisimova 6-2, 7-5, while Taylor Fritz lost to Francisco Cerundolo after winning the first two sets. Coco Gauff also advanced by defeating Cristina Bucsa at Arthur Ashe Stadium. The pattern was clear enough: the event was not simply rewarding the higher seed or the early favorite. It was rewarding the players who could handle the pressure points better than their opponents.
That is also why Zheng’s victory feels significant beyond the single bracket line. It removed Keys, a No. 22 seed, after she had been one point from the fourth round, and it did so in a match that tested both players’ composure. For Zheng, the payoff was obvious. For Keys, it was another reminder that in major tournaments, being close is not the same as being done.
And the larger picture is still open. Both defending champions, Aryna Sabalenka and Carlos Alcaraz, remained in the tournament as Sunday, Sept. 6 approached. So while Saturday offered an upset and a recovery story, it did not yet rewrite the whole championship race. It did, however, show that the 2026 US Open already has the kind of volatility that can change the tone of a draw in a single set.
