Jannik Sinner About

From giant slalom to Grand Slams: the South Tyrolean who turned No. 1 into routine

Jannik Sinner was a national giant-slalom champion before he was a tennis player, raised in German-speaking South Tyrol and only committing fully to the racket at 13, when he left home for Riccardo Piatti's academy in Bordighera. He turned pro at 16, stacked Challenger titles as a teenager, and broke through by winning the 2019 Next Gen ATP Finals. The skiing pedigree still reads in his footwork — compact, balanced, the weight transfer brutal through contact.

The game is built on flat, early-struck groundstrokes off both wings, taken on the rise to rob opponents of recovery time. The two-handed backhand down the line is the signature shot, struck with depth and pace that flattens out rallies most players want to extend. The serve has grown from a liability into a genuine weapon, and his court coverage off a 6'4" frame is among the best on tour. The knock used to be a thin Plan B and patchy net play; both have narrowed as he's matured.

The career arc bent sharply upward in 2024, when Sinner won his first major and ascended to No. 1, building a rivalry with Carlos Alcaraz that now defines the men's game, with Novak Djokovic and Alexander Zverev the other recurring obstacles at the business end of slams. Hard courts are his best surface, but he's pushed deep on clay and grass too, with Wimbledon and the Australian Open the events where he's left the heaviest mark.

As of mid-2026 he sits at world No. 1, the standard-bearer of an Italian era that includes Lorenzo Musetti and Matteo Berrettini. The clay swing through Roland-Garros and the Italian Open is where his ranking gets tested hardest each spring.
