Background and career
Jannik Sinner (born 16 August 2001) is an Italian professional tennis player. He is currently ranked world No. 1 by Association of Tennis Professionals (ATP), and was the year-end No. 1 in 2024. Sinner has won 30 ATP Tour-level singles titles, including five majors, ten Masters and two ATP Finals titles. He led Italy to back-to-back Davis Cup crowns in 2023 and 2024.
Sinner began playing in professional men's events aged 16 and became one of the few players to win multiple ATP Challenger Tour titles at age 17. In 2019, he won the Next Gen ATP Finals and the ATP Newcomer of the Year award, and two years later became the first player born in the 2000s to enter the top 10 in rankings. Sinner won his first ATP Masters 1000 title at the 2023 Canadian Open and finished the season as runner-up at the ATP Finals. At the 2024 Australian Open, Sinner defeated world No. 1 Novak Djokovic followed by Daniil Medvedev in a five-set final to win his first major title. He went on to win both the US Open and the ATP Finals to finish the year at the top of the ATP rankings, becoming the first Italian player to reach world No. 1.
In 2025, Sinner reached the finals of all four majors, winning at the Australian Open and Wimbledon, and losing to Carlos Alcaraz in a five-set epic at the French Open as well as at the US Open. In 2026, Sinner defended his Wimbledon title and won a record five consecutive ATP Masters 1000 titles, becoming the second and youngest player to complete the Career Golden Masters since the series started in 1990 (at 24 years, 9 months and 1 day old).
Jannik Sinner was born 16 August 2001 to Hanspeter Sinner and Siglinde Rauchegger in Innichen, in the Northern Italian province of South Tyrol. His native language is German. He grew up in the town of Sexten in the Dolomites, the family hometown, 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. Sinner began skiing at age three and competed in his first ski races at the age of eight. He began playing tennis at age seven. 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 in 2008 and becoming a national runner-up at age 11 in 2012.
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, where Sinner had to take individual lessons with Mayr as no child his age there was at his level and he was much faster than the older children. Nonetheless, tennis was still only his third priority, behind skiing and football. In the mornings he competed in ski races and in the afternoons he played football matches for AFC Sexten (Youth).
