Jannik Sinner
Jannik Sinner (born 16 August 2001) is an Italian professional tennis player. He has been ranked world No. 1 in men's singles by the Association of Tennis Professionals (ATP), including as the year-end No. 1 in 2024. Sinner has won 22 ATP Tour–level singles titles, including four majors: two at the Australian Open, one at the Wimbledon Championships, and one at the US Open. He has also won the 2024 ATP Finals, and led Italy to the 2023 and 2024 Davis Cup crowns.
Despite limited success as a junior, 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 Generation 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 Masters 1000 title at the 2023 Canadian Open and finished that season by reaching the final of the ATP Finals and leading Italy to the Davis Cup crown.
At the 2024 Australian Open, Sinner defeated world No. 1 Novak Djokovic and then Daniil Medvedev in a five-set final to win his first major title. He followed by winning three Masters 1000 events, the US Open, and the ATP Finals to finish the year as the world No. 1, the first Italian to reach the top ranking. In 2025, Sinner defended his title at the Australian Open and, following a three-month suspension for the accidental administration of clostebol, finished runner-up at the French Open, losing an epic final to his career rival Carlos Alcaraz. He rebounded by winning Wimbledon over Alcaraz in the final, becoming the first Italian to win the title.
Jannik Sinner was born 16 August 2001 to Hanspeter and Siglinde Sinner in Innichen, in the Northern Italian province of South Tyrol. His mother tongue 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 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).
At age 13, Sinner gave up skiing and football in favour of tennis due to his physique; he was tall, thin, and weighed only 35 kilograms. He also preferred competing in an individual sport directly against an opponent and having more control over the outcome. He moved on his own to Bordighera on the Italian Riviera, Liguria, to train at the Piatti Tennis Center under Riccardo Piatti and Massimo Sartori, a decision his parents supported. There, Sinner lived with the family of Luka Cvjetković, one of his coaches, and later moved out to share an apartment with two boys. Before he began training in tennis full-time with Piatti, he had been playing only twice a week. He graduated[when?] from the Walther Institute, a private economics school in Bolzano.
Sinner began playing tennis on the ITF Junior Circuit. In spite of having limited success as a junior, he moved mainly to the professional tour following the end of 2017. He never played the main draw of any high-level Grade 1 events in singles, and the only higher-level Grade A tournament he entered was the Trofeo Bonfiglio.
Sinner followed up an opening round loss at Italy's Grade A tournament in 2017 with a quarterfinal in 2018. That was the only junior event he played in 2018. He never played any of the junior Grand Slam tournaments. Because he entered so few high-level tournaments, Sinner's career-high junior ranking was a relatively low No. 133.
