Italian sensation Jannik Sinner may not seem like the most powerful player out there, but his game will tell you otherwise. A dominant baseliner with some of the best ground-strokes, Sinner became the first Italian to reach the Australian Open singles final in 2024. In March 2024, Sinner defeated the in-form Grigor Dimitrov to win the Miami Masters.
With his powerful performance, Jannik Sinner sealed a spot in the 2025 Australian Open final, defeating Ben Shelton in the semifinal and Alex de Minaur in the quarterfinals. In the final, Sinner outlasted Alexander Zverev by 6-3, 7-6, 6-3. As the tournament winner, he won a prize money of around A$3,500,000.
Sinner also advanced to the 2024 French Open semifinal and won the 2024 US Open. He emerged victorious at the 2024 Cincinnati Open, winning his second Masters 1000 title, defeating Frances Tiafoe by 7-6, 6-2 in the final. Due to his positive test for the banned anabolic steroid Clostebol, he faced an anti-doping sanction that resulted in the forfeiture of his prize money and points from the Indian Wells tournament. However, he received no further action after the ITIA found him not faulty.
Born on August 16, 2001, in San Candido, Italy, Sinner has won 18 titles in his career so far. He is one of the few current players to have made it to at least the quarter-final stage at all four majors, and was also the Davis Cup winner in 2023. Before taking up tennis professionally, the 23-year-old actually enjoyed skiing and football more than tennis. However after turning pro in 2018, there was no looking back for the Italian.
