He grew up in the town of Sexten in the Dolomites, where his father worked as a chef and his mother as a waitress at a ski lodge. He has an older adopted brother, Mark, who was born in Russia in 1998.

๐ฟ Junior Skiing and Tennis Beginnings
He was one of Italy’s top junior skiers from seven to 12 years old, winning a national championship in giant slalom at age seven. While training in skiing, Sinner gave up tennis for a year at age seven before his father pushed him to return to the sport.
When he resumed playing, Heribert Mayr was his first regular coach. Sinner’s grandfather drove him to Tennis San Giorgio early in the morning for individual lessons.
At age 13, Sinner gave up skiing and football in favour of tennis due to his physique. He moved to Bordighera on his own to train at the Piatti Tennis Center under Riccardo Piatti and Massimo Sartori.
