Ben Shelton captured the biggest title of his career at the Masters 1000 event in Toronto, completing a come-from-behind 6-7 (5), 6-4, 7-6 (3) victory over Karen Khachanov in the final on Thursday night. The 22-year-old American’s title run produced immediate consequences on the ATP list.

Shelton rises from No. 7 to No. 6 on the ATP rankings, passing former world No. 1 Novak Djokovic for a new career-high. It is the fourth consecutive week in which he has set a personal best; he has reached a new career-high every week in the four weeks since Wimbledon. “BEN SHELTON’S CASCADE OF CAREER-HIGHS:” appears as a concise reflection of that run.

The new ATP rankings are backdated to this past Monday, August 4th. The next update will come after Cincinnati on Monday, August 18th. Shelton made his Top 10 debut a few weeks before Wimbledon, at No. 10, after a semifinal showing on the grass of Stuttgart. With a deep run at the Cincinnati Masters 1000 event he could break into the Top 5.

Shelton is now 330 points behind No. 5 Jack Draper. He also has 40 more points dropping on the next rankings than Draper, and the Brit is also not competing in Cincinnati this year.

There was movement elsewhere in the rankings after Toronto. Karen Khachanov rises from No. 16 to No. 12 after reaching his second Masters 1000 final of his career. The 29-year-old, who won his first Masters 1000 title in Paris in 2018, reached a career-high of No. 8 the following year.

Alexei Popyrin made his Top 20 debut, rising from No. 26 to No. 19 after reaching the quarterfinals in Canada. The Australian was the defending champion at the event, winning it in Montreal a year ago.

Aryna Sabalenka reached the 50-week milestone at No 1 in the WTA rankings after the Canadian Open, extending a run of 42 consecutive weeks at the top since her return to No 1 in October 2024. Sabalenka sits at 12,010 points and holds a 4,341-point lead over Coco Gauff, with Iga Swiatek a further 736 points back in third.

Sabalenka did not play the WTA 1000 event in Montreal but remained assured of keeping the No 1 position. She will face a significant points defence period before the US Open, with 3,000 points set to drop from her total (1,000 at the Cincinnati Open and 2,000 at Flushing Meadows), though she can recover those points by deep runs at those events.

The Canadian Open provided major movement elsewhere. Eighteen-year-old Victoria Mboko won her maiden title, having been awarded a wildcard and defeating Sofia Kenin, Coco Gauff, Elena Rybakina and Naomi Osaka en route to the final. Mboko beat Osaka 2-6, 6-4, 6-1 to complete her run. Her breakthrough lifted her from No 85 before the tournament to No 24, a rise of 61 places from her season start at No 333.

Naomi Osaka’s runner-up finish also produced a sizeable jump to No 25, up 24 places, and both young winners are now set to be seeded at the 2025 US Open.

Other notable ranking changes: Clara Tauson climbed four places to a career-high No 15 after reaching the semi-final. Madison Keys moved up two places to No 6 and Elena Rybakina rose two spots to No 10. Paula Badosa slipped two places to No 12. Emma Raducanu fell six places to No 39 after a third-round exit but remains British No 1. Sonay Kartal sits at No 48 and Katie Boulter dropped seven places to No 50. Surprise quarter-finalist Jessica Bouzas Maneiro rose nine places to No 41.

Victoria Mboko’s week in Montreal altered the arc of a season and a career. The 18-year-old captured her first WTA title at a WTA 1000 event and moved from No. 85 to No. 24 in the new WTA rankings.

Mboko’s ascent has been rapid. She started 2025 at No. 333, won five ITF Circuit titles early in the year to soar into the Top 200 by March, and broke into the Top 100 in June after reaching the third round of Roland Garros as a qualifier. Her run in Montreal pushed her through multiple milestones: first WTA quarterfinal, first WTA semifinal and first WTA final, all en route to the biggest title of her young career.

The nature of her victories made the week particularly notable. Mboko became the second-youngest woman in the Open Era to defeat four Grand Slam champions at the same WTA event, beating Sofia Kenin in the second round, Coco Gauff in the fourth round, Elena Rybakina in the semifinals and Naomi Osaka in the final. The youngest to complete that sequence was Serena Williams, who did so as a 17-year-old at the 1999 US Open.

With the ranking jump Mboko is now the highest-ranked Canadian on either the ATP or WTA lists, just ahead of No. 26 Leylah Fernandez, No. 28 Felix Auger-Aliassime, No. 30 Denis Shapovalov and No. 35 Gabriel Diallo.

Mboko will head to Cincinnati with a Special Exempt into the main draw after still competing in Montreal’s main draw. By reaching the Montreal final she also received a Performance Bye in Cincinnati and will open her campaign in the second round against No. 14 seed Diana Shnaider, likely on Saturday or Sunday.

Naomi Osaka also climbs after Montreal, moving from No. 49 to No. 25. It is her first time inside the Top 30 or the Top 40 since coming back to the tour as a mom at the beginning of last year. Osaka also received a Performance Bye in Cincinnati and will meet No. 20 seed Linda Noskova in the second round. Clara Tauson rose from No. 19 to No. 15 after reaching the semifinals in Canada before falling to Osaka.
