Sabalenka overcomes Townsend in US Open fourth round, set to face Wimbledon champion Noskova in quarterfinals

Taylor Townsend had just closed her service game to lead 3-1 in the second set as she walked to the baseline for game seven, with the Arthur Ashe crowd fully behind her. Then a double fault — a second consecutive missed serve — brought her back to earth. The moment did not simply give the break back to Aryna Sabalenka; it exposed the thin line between a brave performance and a real victory. Sabalenka, the No. 1 seed and defending champion, did not panic. She tightened her game, pushed Townsend into longer rallies and let her opponent collapse from her own error. The last four games belonged to Sabalenka, closing the match 6-4, 6-3. It was her sixth consecutive appearance in the US Open quarterfinals — a level of consistency rarely seen in the volatile WTA era. People look at the rankings; I look at what the rankings hide. Townsend, 28, was unseeded and had been described as a potential threat to the top seed. She played very bravely, produced some excellent returns and showed no fear of her opponent's credentials. But she led 3-1 in the second set, then double-faulted in game seven, then lost the break, then dropped the final four games. Those who only check the scoreline will say Sabalenka controlled the match. Those who watched closely will understand that Townsend lost not because she lacked power, but because she had been playing on the edge for too long with nowhere left to retreat. There are data points that do not need to be loud; they only need someone patient enough to read them. The first set between Sabalenka and Townsend featured seven breaks of serve in total. Seven times a server faltered in one Grand Slam set is an unusual number even for top players. It showed Sabalenka was not dominating on serve as she usually does; Townsend had found a way to read her delivery. But Sabalenka did what a champion must do: she made fewer errors, took her chances at the right moments and conserved energy for the decisive games. This victory was not beautiful in a theatrical sense, but it was the kind of win that comes from knowing Grand Slams do not award style points. On the other side of the draw, Linda Noskova had just survived a completely different battle. The 2026 Wimbledon champion needed three sets to get past Marta Kostyuk, winning 7-5, 5-7, 6-4. In the opening set, Noskova used her backhand to control Kostyuk's serve, breaking in the eleventh game before closing it out. The second set was where nerve was truly tested: Noskova held two match points, Kostyuk saved both, levelled at 5-5 and then broke in game twelve to take it 7-5. Kostyuk also committed two double faults and an unforced error in game seven, but the real story was not her mistakes — it was the way Noskova kept her composure after letting the set slip away. She returned in the third, played more solidly and won 6-4. Many analysts still frame Noskova as a young player who arrived from Wimbledon, but I see clear evolution in her game at this US Open. Her Wimbledon title is no longer the shock of a rising talent; it has become the foundation for a more patient game on hard courts. Noskova's backhand is not just a weapon for winners; it is a tool to control tempo and push opponents out of their comfort zone. Against Kostyuk, she did not try to end points quickly through emotional shot-making. She chose to suffocate with angles and spin. Elite sport is the art of repetition — and of breaking repetition. Sabalenka is repeating her deep-run pattern at the US Open; Noskova is breaking the assumption that a Wimbledon champion only thrives on grass. Their quarterfinal is therefore not simply a duel between the No. 1 seed and a young contender. It is a test of adaptability: Sabalenka must prove she can break down Noskova's disciplined defence, while Noskova must prove the two match points she saved against Kostyuk were not a lucky moment. I have followed Sabalenka through many US Open campaigns, and I have never seen her enter a quarterfinal with as many question marks about her serve as this year. But I have also seen her turn those question marks into fuel before. If we look at head-to-head history and Grand Slam experience, Sabalenka is clearly the favourite. She has navigated these kinds of matches many times, while Noskova is only beginning to build her own legacy. But the real pressure in this quarterfinal is not on Noskova. She is a Wimbledon champion with no significant ranking points to defend at Flushing Meadows, and she just won a long, emotional three-setter. It is Sabalenka who is defending a title, chasing a hat-trick and carrying the expectations of a country that sees her as the face of women's tennis. The pressure of the rankings never lies, but it also never helps a player serve more accurately in the decisive game. One more thing the scoreboard cannot show: Townsend gave Sabalenka an expensive lesson about losing focus at delicate moments. Sabalenka won the last four games, but she also allowed Townsend to lead 3-1 in an important set. If Townsend could exploit that lapse, then Noskova's more disciplined game is perfectly capable of doing the same. The quarterfinal question is not whether Sabalenka is stronger. It is whether she can keep her attention fully intact for two hours against an opponent who never beats herself. That is the question only Sabalenka can answer with her racket on Arthur Ashe.
