Jannik Sinner will remain in the World No. 1 spot in the latest ATP rankings despite coming up short in his bid to defend the 2024 Canadian Open title in Montreal.
Sinner knew beforehand that he would remain number one after the tournament, as Novak Djokovic and Carlos Alcaraz withdrew from the first ATP Masters 1000 of the North American summer hard-court swing.
Alexander Zverev added 150 points in fourth place to increase his lead over Daniil Medvedev. Andrey Rublev rose two spots to sixth after his runner-up finish in Montreal.
Casper Ruud and Grigor Dimitrov each climbed a spot into the eighth and ninth spots, while Alex de Minaur cascaded three places to 10th for missing last week's event. The Top 10 remained unchanged after Canada.
Taylor Fritz took back his spot as the American No. 1 from Tommy Paul and settled in 12th place. Ben Shelton is just below them in 14th, while Sebastian Korda motored three places to a new career-high ranking of No. 15 following his semifinal finish in Montreal.
Alexei Popyrin is the biggest mover in the world's Top 30. The big-serving Australian sensationally lifted the Canada Open with a tremendous performance against Rublev in the final.
Popyrin moves to a new best ranking of No. 23 and is his country's No. 2. Matteo Arnaldi is another player who made waves in Canada. The 23-year-old from Sanremo soars to a career-high of No. 30. Just below him is Flavio Cobolli in the 31st spot, another Italian enjoying a great summer in the United States.
Jiri Lehecka fell outside the seeding positions for the US Open (35th). The young Czech hasn't played since Madrid because of injury. Nuno Borges scored two crucial wins in Montreal to become the new World No. 39.
Gael Monfils' winless streak extended to three matches in Montreal and drops to 46th. Brandon Nakashima has re-entered the Top 50 after reaching the round of 16 as a qualifier at the Canadian Open, but Alejandro Davidovich Fokina (53rd) fell outside that half-centurion club.
Arthur Rinderknech, who was close to exiting the Tip 100 this season, also impressed this past week after advancing into the last 16 as a qualifier. He rejoins the Top 60 (59th).
Two other Australians rose a few spots in the rankings. These are Rinky Hijikata (65th) and James Duckworth (67th). Denis Shapovalov inches closer to a Top 100 return, although he failed to make an impression on home soil (he lost in the first round).
Hugo Dellien won the Bonn Challenger by beating home player Maximilian Marteter in the final. It was the Bolvian's second title in August (he also won the Liberec Challenger). He climbed to his best ranking since January (107th).
Another big mover inside the Top 200 is Jacob Fearnley, who famously pushed Novak Djokovic to four sets in a match at this year's Wimbledon. The British man moved to 162nd in the standings after winning the Lincoln Challenger.
A couple more players finished on the winner's podium on the ATP's second tier this past weekend, and their ranking surged. 19-year-old Lithuanian Vilius Gaubas won his first Challenger title in Cordenons by losing just one set all week.
Facundo Mena won the Bogota Challenger. Both players make their Top 200 debuts (up to 186th for Gaubas and 195th for Mena). Be sure to stay up to date with all the changes by checking our rankings page.
