Career
Jannik Sinner was born in San Candido, South Tyrol, on August 16, 2001, and grew up on the snows of the Dolomites as a skier before discovering tennis at the age of eight. His progression in the ATP circuit is one of the fastest in modern tennis history: he entered the top 100 in 2019 and the top 10 in 2021. The definitive leap came in 2024 when he won the Australian Open in an epic final, coming back from two sets down, conquered the US Open, and became the first Italian in tennis history to reach number 1 in the ATP world rankings. In 2025, he defended his title at the Australian Open, confirming himself as the most dominant player on the circuit. With the Italian National team, he led the Azzurri to victory in the Davis Cup in both 2023 and 2024 — a historic and unrepeatable feat. Powerful, precise, and mentally indestructible, Sinner has revolutionized Italian tennis, bringing it to the absolute top of the world.
