Zheng Qinwen defeated Alina Charaeva 6–1, 2–6, 6–4 in the Beijing fourth round on October 7, 2026. After 2 hours and 11 minutes, her fifth break of the match supplied the finish.
Zheng struck 14 winners in the opening set. Charaeva reversed the contest in the second, winning all 14 points played behind her first serve and converting both break chances. Her service and return results together explain how the match reached a deciding set.
Zheng moved ahead 5–2 in the third but was broken as Charaeva closed to 5–4. Having missed the chance to finish on serve, Zheng broke immediately to secure her place in the quarterfinals. All four of her Beijing matches had reached a third set.
