The 24-year-old Italian, who first reached the summit of men’s tennis in June last year, will return to the top when the ATP rankings are updated on Monday following Carlos Alcaraz’s early exit in Paris. Sinner’s victory marks his fifth title of the 2025 season and his first Masters 1000 crown since Shanghai in October 2024.
Having lost the No. 1 spot after his US Open final defeat to Alcaraz in September, the triumph in Paris represents a satisfying comeback for Sinner, who also lost to the Spaniard in a classic five-set Roland Garros final earlier this year.
Despite missing three months at the start of 2025 after testing positive for traces of clostebol, Sinner has bounced back spectacularly, claiming major titles at the Australian Open and Wimbledon before adding Paris to his growing trophy cabinet.
In Sunday’s final, Sinner struck first, breaking Auger-Aliassime in the opening game with his trademark baseline power. Though the Canadian ninth seed remained resilient, Sinner’s consistent serving ensured he clinched the first set 6-4.
The second set was a tighter contest, with both players displaying superb shot-making and composure under pressure. Auger-Aliassime saved multiple break points early on and showed tremendous grit to keep the match on serve.
However, Sinner’s relentless pace and precision forced the set into a tie-break, where he raced ahead 3-2 and sealed the title with a blistering backhand winner down the line.
For Auger-Aliassime, the loss denied him a fourth title of the season but strengthened his bid to qualify for the ATP Finals in Turin, as his run to the final lifted him above Lorenzo Musetti in the race standings.
Sinner’s Paris triumph not only underscores his dominance in 2025 but also reaffirms his position as one of tennis’s modern greats. With five titles and a return to world No. 1, the Italian heads into the ATP Finals brimming with confidence and momentum.
