Jannik Sinner has added another landmark achievement to his remarkable career after beginning his 81st week as World No. 1, moving into the ATP's all-time top 10 for the most weeks spent at the summit of the men's rankings.
The 24-year-old Italian has now surpassed Carlos Alcaraz's total of 66 weeks at No. 1, while also overtaking former world No. 1s Stefan Edberg (72 weeks) and Lleyton Hewitt (80 weeks).
Sinner first rose to the top of the ATP Rankings on June 10, 2024, following his breakthrough Australian Open triumph. He held the position for 65 consecutive weeks before briefly relinquishing it to Alcaraz earlier this season.

However, Sinner quickly reclaimed the top spot after defeating Alcaraz to win the Monte Carlo Masters and has now remained World No. 1 for 15 straight weeks.
His dominance is also reflected in the rankings, where he holds a commanding 4,970-point lead over world No. 2 Alexander Zverev, giving him a comfortable cushion heading into the second half of the season.
Sinner's next targets are already in sight. If he maintains his position, he could soon join another elite group by becoming only the eighth player in ATP history to spend at least 100 weeks as World No. 1.
The next names ahead of him on the all-time list are Andre Agassi with 101 weeks and Bjorn Borg with 109.
The upcoming North American hard-court swing could further strengthen Sinner's grip on the top ranking. With relatively few ranking points to defend from last year's Canadian Open and Cincinnati Masters, the Italian has an opportunity to extend his advantage.
Meanwhile, Alcaraz faces greater pressure as he will defend a significant haul of ranking points from his title-winning performances at both tournaments last season, potentially allowing Sinner to widen the gap if results go his way.
