Jannik Sinner became the first Italian player, male or female, ever to hold the ATP world No. 1 ranking on 10 June 2024.
The milestone arrived not with a single match victory, but through the relentless mathematics of the tour. Across the spring months, Sinner accumulated points with a steady command that carried him past every rival in the rankings table.
A nation's first summit
The ranking logic was simple and severe. His results in early 2024 pushed his point total past Novak Djokovic's. When the new list was published, Italy stood alone at the top of men's tennis.
Five months earlier in Melbourne, Sinner had fought back from two sets down to beat Daniil Medvedev and claim his maiden Grand Slam title. That victory gave him the first major for an Italian man at the tournament, and it laid the foundation for everything that followed.
From Melbourne to the top of the world
The climb had been gathering speed since late 2023, when he led Italy to its first Davis Cup title in 47 years. By September 2024 he would add a US Open trophy and finish the season without a single straight-sets loss.
No Italian woman had ever held the WTA No. 1 ranking either. The number beside his name confirmed what the scorelines had been whispering for months.
A quiet certainty now sat in his corner of the sport. The hard red-headed kid from the Dolomites had shifted the axis of men's tennis towards a country that had waited a very long time for this view.
