Zheng Qinwen, the 7th seed and Olympic gold medalist, showcased her skill at the US Open by defeating unseeded German Jule Niemeier 6-2, 6-1, marking her first straight-sets victory in a major this year. Zheng dominated the match with eight aces and five break points while capitalizing on Niemeier's struggles, which included five double faults due to a foot injury. This victory avenged her previous third-round loss to Niemeier at the 2022 US Open and set her up for a quarterfinal match against Croatia's Donna Vekic, who recently lost to her in the Olympic final. In her post-match comments, Zheng expressed relief at finally achieving a straight-sets win and recognized the vital support from her fans, who encouraged her with chants of 'jiayou'. The quarterfinal match against Vekic is highly anticipated as both players seek to leverage their recent encounters on different surfaces.
