Jannik Sinner, 25, has already been world number one for 84 weeks.

SESTO PUSTERIA – Jannik Sinner is celebrating his 25th birthday. The world No. 1, born on August 16, 2021, won his 30th Wimbledon title, the fifth Grand Slam of his career, and is now aiming for the US Open. All he needs is Roland Garros, his goal for 2027. Meanwhile, he has spent almost the last two and a half years at the top of the ATP rankings, where he returned in April 2026. The latest rankings see him firmly in the lead with 13,450 points, culminating in Jannik Sinner's 84th week as world No. 1, who sits first with 13,450 points. Next in line are Carlos Alcaraz, No. 2, with 8,160 points, but like Sinner, was absent from Cincinnati, and Germany's Alexander Zverev, No. 3 with 8,090 points, who could overtake the Spaniard by winning in Cincinnati. Sinner, obviously, is aiming to repeat the success he achieved at the US Open last year. Arithmetically, whatever happens, no one will be able to dislodge Sinner from his top spot until next October. And this says a lot about the gap the champion from Alto Adige has dug over his closest rivals. An extraordinary talent with a low profile and always anchored to family values. On turning 25, Sinner finds himself having won the same number of Slams as Novak Djokovic at the same age. These numbers are a predestined success, which are driving the Italian tennis movement. The Italian players in the Top 20 are back to four, thanks to the exploits of Luciano Darderi who in Canada reached the first quarterfinal of his career in a Masters 1000 and rose to number 20, behind Sinner, Flavio Cobolli (10) and Lorenzo Musetti (15). The top 100 include Matteo Arnaldi (34), Matteo Berrettini (42), Mattia Bellucci (81) and Lorenzo Sonego (88). Worth noting is the progression of Andrea Guerrieri, from world number 511 at the start of 2026 to 188: his first time in the Top 200 following his appearance in the final at the Challenger in Grodzisk Mazowiecki.
