Born in Innichen, South Tyrol, Italy, Sinner grew up watching his parents work hard. His father, Johann, is a chef, and his mother, Siglinde, worked as a waitress both at the Talschlusshutte ski lodge. His older brother, Marc, was adopted in 1998 and shares a close bond with Jannik, though he once skipped his brother’s final to attend an F1 event.

Here, who else might be in Sinner’s player’s box: Cahill joined Sinner's coaching team in 2022, and he’ll be retiring at the end of this year, despite protests from Vagnozzi. Wimbledon will be one of his last tournaments with Sinner.

Sinner has several endorsement deals with major brands. In 2024, those deals netted him $15 million and made up the majority of his net worth. His sponsors include Nike, Head, Rolex, Panini, Gucci, Lavazza, Intesa Sanpaolo Assicura and FastWeb S.p.A.

Before dating Kalinskaya, Sinner was linked to Italian model Maria Braccini. Kalinskaya had also dated Aussie star Nick Kyrgios. Right now, though, Sinner’s mind is firmly on Wimbledon. The Italian ace is chasing his first title at the All England Club, and this time, he's going all alone.

Novak Djokovic's Wimbledon run was brought to an abrupt and miserable end, following a straight sets defeat to a commanding Jannik Sinner. The Italian proved far too hot for Djokovic to handle, giving the tennis icon the run around from the opening serve.
