Early life and background

Image Source: Google

Jannik Sinner was born on 16 August 2001 in Innichen, South Tyrol, Italy, to Hanspeter (a chef) and Siglinde (a waitress). His mother tongue is German, and he grew up in Sexten, a town in the Dolomites. He has an older adopted brother, Mark, who was born in Russia.

Sinner began skiing and playing tennis at age three. He participated in his first ski race in first grade and played his first tennis tournament at age five. From ages seven to twelve, he was one of Italy's top junior skiers, winning a national championship in giant slalom at age seven in 2008 and becoming a national runner-up at age eleven in 2012. However, tennis remained his third priority after skiing and football.

At age seven, Sinner gave up tennis for a year before his father encouraged him to return to the sport. He began working with his first regular coach, Heribert Mayr, and was driven by his grandfather to Tennis San Giorgio for individual lessons, as he was much faster than children his age. Despite excelling in tennis, he continued to prioritize skiing and football until the age of 13, when he chose tennis over both due to his physique and preference for individual competition.

After deciding to focus on tennis, Sinner moved to Bordighera, Liguria, to train at the Piatti Tennis Center under Riccardo Piatti and Massimo Sartori. His parents supported the decision, and he lived with the family of coach Luka Cvjetković before later sharing an apartment with two boys. He trained full-time at the center, having previously only played tennis twice a week.

Sinner graduated from the Walther Institute, a private economics school in Bolzano.
