Rankings Watch: A 61-spot surge sends Mboko into the Top 25

From four Slam wins to a Top 25 debut, Victoria Mboko’s seven-match run in Montreal leads a flurry of movement, with Naomi Osaka and Elena Rybakina also returning to familiar territory.

Editor’s Note: The PIF WTA Rankings have been updated following the conclusion of the Omnium Banque Nationale in Montreal. This update includes points from that event, as well as WTA 125 and ITF tournaments held during the weeks of July 21 and July 28. Points from Washington and Toronto 2024 have dropped off. A second and final update including this week's ITF results will be published on August 10, which will be the official August 11 rankings for historical and record purposes.

This time last year, Victoria Mboko was ranked No. 351 and had just lost her opening match at a W50 in Zagreb to Eszter Meri.

Twelve months later, the 18-year-old Canadian is a WTA 1000 champion after electrifying the Montreal crowd with a seven-match run to the title.

Among her many feats, Mboko became the 12th player in the Open Era to defeat four Grand Slam champions in a single tournament (Sofia Kenin in the second round, Coco Gauff in the fourth round, Elena Rybakina in the semifinals and Osaka in the final).

Mboko is the first player to achieve this since Ons Jabeur and Elina Svitolina at Wimbledon 2023 and the second youngest in the Open Era following Serena Williams at the US Open 1999.

She breaks into the Top 25 for the first time, rising 61 spots from No. 85 to No. 24, and becomes the highest-ranked player from Canada.

Osaka returns to Top 30, Rybakina back in Top 10

Naomi Osaka may have come up short in the final against Mboko, but Montreal still marked a breakthrough in her first tournament with new coach Tomasz Wiktorowski. She defeated three Top 20 players in a single event for the first time since Beijing 2019, reached her second final of the year and her first at WTA 1000 level since Miami 2022.

Osaka rises 24 spots from No. 49 to No. 25, returning to the Top 30 for the first time since January 2022.

Former Wimbledon champion Elena Rybakina fell out of the Top 10 in April, ending a 26-month stay in that tier. A run to her fifth semifinal of 2025 in Montreal bumps her up two spots, re-entering the Top 10 at No. 10.

New career highs for Tauson, Bouzas Maneiro, Ito

Three players who made deep runs in Montreal rise to new career highs this week:

Clara Tauson notched back-to-back Top 10 wins, defeating Iga Swiatek in the fourth round and Madison Keys in the quarterfinals. The Dubai runner-up in February, Clauson, 22, made her second WTA 1000 semifinal of the season. She moves up four places to No. 15.

Fresh off her first Grand Slam fourth-round showing at Wimbledon, Spain's Jessica Bouzas Maneiro reached her first WTA 1000 quarterfinal in Montreal. The 22-year-old climbs nine spots to No. 42.

Aoi Ito’s unorthodox game has drawn attention as she’s broken through at tour level, and it helped the Japanese qualifier earn her first Top 10 win over Jasmine Paolini in the Montreal second round. The 21-year-old climbs 16 spots to No. 94, returning to the Top 100.
