Zheng Qinwen, ranked 121st in the world, beat the eighth-ranked Iga Swiatek 7-5, 6-3 in New York for the biggest win of her career, and for the second match running she did it after trailing 0-5 in a set. Everything had pointed the other way beforehand, with Swiatek leading their head-to-head 7-1. Yet Zheng, who missed much of the 2025 season with an elbow injury, punished 28 unforced errors from the Pole and refused to buckle once the pressure arrived. "I started the match not so well," she admitted on court. Victory takes her seventh consecutive win at Flushing Meadows and a third US Open quarter-final, where Elena Rybakina awaits.
