Overview
- Elena Rybakina beat Zheng Qinwen 3-6, 6-1, 6-4 to reach her first US Open semifinal and secured the points needed to claim the WTA No. 1 spot.
- That result, achieved on Wednesday, means the official rankings update next Monday will list Rybakina as world No. 1, displacing Aryna Sabalenka.
- The US Open women's semifinals now feature the top four seeds — Aryna Sabalenka, Elena Rybakina, Jessica Pegula and Coco Gauff — a rare alignment that frames both the title race and the ranking change.
- Rybakina will be the first player from Kazakhstan to reach No. 1 and at 27 years and 89 days she is the second-oldest woman to debut at the top of the WTA rankings.
- The immediate questions are whether Rybakina can convert the new ranking into a Grand Slam title and how the shift will affect national interest in Kazakhstan and the wider WTA rivalries in the weeks ahead.
