Gauff on brink of U.S. Open quarterfinals; Zheng stuns Swiatek

Coco Gauff is one set away from reaching the U.S. Open quarterfinals, leading Iva Jovic in their all-American fourth-round match. Elena Rybakina and Mirra Andreeva have already advanced, while Zheng Qinwen upset Iga Swiatek after trailing 5-0 in the first set. The night session also features Alexander Zverev and Learner Tien.
Gauff claimed the opening set 6-1, but Jovic has rallied to lead 4-3 in the second set, making the match more competitive. Zheng's comeback was remarkable, erasing a 5-0 first-set deficit to defeat Swiatek 7-5, 6-3, while Rybakina and Andreeva have already secured quarterfinal berths.
In the men's draw, Khachanov holds a double-break lead over Tien in the fourth set after Tien took the third. Gea is serving for the match against Van de Zandschulp, and Zverev is slated to face Darderi later in the night session.
These results could significantly reshape the competitive hierarchy in women's tennis, with Zheng's upset of Swiatek potentially signaling a generational shift. For American audiences, the deep runs of Gauff, Jovic, and Tien may boost domestic viewership and youth participation. Additionally, the night-session matchups could influence future scheduling and sponsorship priorities, as broadcasters and brands react to emerging stars and shifting fan demographics.
