ATP rankings, which determine the world rankings for male professional tennis players, remain unchanged at the top on Monday, September 28, 2026, with Italian Jannik Sinner maintaining his position as the world number one. Sinner has held this spot despite a lengthy absence from the tour due to a knee injury. His lead is significant, with 11,000 ranking points, well ahead of Alexander Zverev (9,630) and Carlos Alcaraz (5,060). Other notable players in the top eight include Ben Shelton, Félix Auger-Aliassime, Daniil Medvedev, Flavio Cobolli, and Frances Tiafoe. French player Arthur Fils makes a notable breakthrough by entering the world top 10 for the first time, securing the ninth position. This marks the first time since 2020 that a French player has been in the top 10, ending a nearly six-year absence. Since the establishment of the ATP rankings in 1973, only 13 French players have ever reached the world top 10. Yannick Noah was the first in August 1982, and Fils is the 13th to achieve this milestone. Fils' rise has been rapid. At the end of the 2025 season, he was ranked 40th in the world. After an absence of eight months, his ranking dropped to around 42nd. However, since his return, he has had a string of strong performances, including a final appearance in Doha, quarterfinals in Indian Wells, semifinals in Miami and Madrid, and victories in Barcelona and Cincinnati. His win in Cincinnati marked the first time a French player had claimed an ATP Masters 1000 title in 12 years, since Jo-Wilfried Tsonga's victory in Toronto in 2014. Fils is 22 years and 108 days old, making him the third youngest French player to enter the top 10, following Richard Gasquet and Yannick Noah. The gap between Fils and the previous French player in the top 10, Lucas Pouille, was nearly eight years. Meanwhile, Novak Djokovic climbed to 11th place, while other players such as Taylor Fritz and Casper Ruud dropped in the rankings. Ugo Humbert and several other French players also saw shifts in their positions, reflecting the dynamic nature of the ATP rankings.
