SEO Description: Elena Rybakina rises to World No. 1 and Marta Kostyuk breaks into the Top 10 as the latest WTA rankings update brings milestones for players across the draw.
Rybakina reaches the summit
Rybakina’s ascent completes a rapid shift at the top of the women’s game. Only a month earlier, she had finished runner-up in Toronto and cut Aryna Sabalenka’s lead at No. 1 to just 54 ranking points.
- Rybakina is the new World No. 1.
- Kostyuk has made her first appearance inside the Top 10.
- Sabalenka previously became the 10th player to spend 100 weeks at No. 1 in the PIF WTA Rankings.
- Iga Swiatek had returned to the Top 5 after a four-week absence following her Toronto title.
The upper reaches of the rankings have remained particularly competitive. Jessica Pegula and Coco Gauff had held the No. 3 and No. 4 positions, respectively, during the recent North American hard-court stretch.
Career-best moves throughout the rankings
Kostyuk’s milestone is part of a wider run of breakthroughs from emerging and established players alike. Sara Bejlek made her Top 30 debut after reaching the Cincinnati semifinals, while Linda Noskova and Alexandra Eala each posted new personal bests.
- Alexandra Eala became the first Filipina to enter the Top 20 after winning the Washington title.
- Kristina Liutova, the 16-year-old Memphis champion, surged 103 places to a career-high ranking.
- Lilli Tagger, Tamara Korpatsch and Daria Snigur all cracked the Top 50 for the first time after standout weeks in Prague and Hamburg.
- Mayar Sherif returned to the Top 50 for the first time since April 2025 and has also climbed back inside the Top 60 in a later update.
- Barbora Krejcikova has returned to the Top 30.
- Fiona? No additional player details were provided beyond the listed milestones.
Thailand also recorded a landmark week through Lanlana Tararudee and Mananchaya Sawangkaew, while Oleksandra Oliynykova, Alina Korneeva and four WTA 125 finalists achieved new ranking milestones.
Recent results driving the movement
Ranking points continue to reflect a busy sequence of tournaments and surface swings. The grass-court segment produced its own statistical landmarks, including the longest matches of the swing, notable match-point escapes and the tour’s most dominant championship run.
At the US Open, Cristina Bucsa defeated Himeno Sakatsume in a three-set match settled by three tiebreaks. It was the fourth triple-tiebreak contest in US Open Open Era history.
Elsewhere, Diane Parry, Li and Nikola Bartunkova have each reached new career-high positions, adding further movement below the elite tier as the WTA draw continues to reshape itself.
