## Early life and background

Jannik Sinner was born 16 August 2001 to Hanspeter and Siglinde Sinner in Innichen in the province of South Tyrol in Northern Italy. 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 named Mark, who was born in Russia. Sinner began both skiing and playing tennis at age three. He did his first ski races in first grade, played his first tennis tournament at the age of five. He was one of Italy's top junior skiers from seven to twelve years old, winning a national championship in giant slalom at age seven in 2008 and becoming a national runner-up at age eleven in 2012.
While training in skiing Sinner gave up tennis for a year at the age of seven before his father pushed him to return to the sport. When he resumed playing, he began working with Heribert Mayr as his first regular coach. His grandfather would drive him to Tennis San Giorgio early in the morning, where Sinner had to take individual lessons with Mayr as no child his age there could keep up with his level and he was much faster than older children. Nonetheless, tennis was still only his third priority behind skiing and football. In the morning, he competed in a ski race, and in the afternoon, he played a football match 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 decided to move on his own to Bordighera in Liguria on the Italian Riviera to train at the Piatti Tennis Center under Riccardo Piatti and Massimo Sartori, a decision his parents supported. At the centre, Sinner lived with the family of Luka Cvjetković, one of his coaches, and later moved out to share an apartment with two boys. Before Sinner began training in tennis full-time with Piatti, he had been playing only twice a week. He graduated from the Walther Institute, a private economics school in Bolzano.

## Junior career

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.
He 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.

On 20 August, an independent tribunal announced that Sinner had positive results for the banned substance clostebol in separate tests from March 2024. The tribunal accepted Sinner's explanation that the clostebol had entered his body via massages administered by his physiotherapist, who had used a treatment which contained clostebol to treat an injury on his own hands. The decision by the tribunal was to determine that Sinner bore "no fault or negligence" and no period of ineligibility would apply, but that he would forfeit prize money and ranking points earned at the Indian Wells tournament held in March. The World Anti-Doping Agency appealed the decision, and in February 2025 the appeal reached a settlement under which the positive drug tests were determined to be due to inadvertent contamination and Sinner was suspended for three months. The overall process was criticized by some active and former players.

In November, Sinner won the season's ATP Finals in Turin, Italy, by defeating Fritz.

He ended the 2024 season by defeating Netherlands' Tallon Griekspoor in the Davis Cup final, to win Italy's second consecutive title.

For his 2024 positive test for Clostebol, the World Anti-Doping Agency (WADA) announced in February 2025 they entered a "case resolution agreement" with Sinner. WADA accepted the cause and explanation of the positive test but stated "an athlete bears responsibility for the entourage’s negligence". A three-month suspension was handed down with Sinner being ineligible from tennis competition from 9 February to 4 May 2025. Some players reacted with criticism of the process, notably Novak Djokovic who at a press conference at the 2025 Qatar Open expressed the opinion that "the majority of the players feel like there is favouritism happening" citing the advantages that high ranked players have to rapid legal advice.

## Playing style

Sinner is an aggressive baseliner and is one of the hardest hitters on the ATP tour. Sinner's groundstroke strength is his two-handed-backhand, which he hits with more topspin than any other player on the tour, registering an average of 1858 revolutions per minute on the shot along with the fifth-best average speed of 111.2 km/h (69.1 mph).
Sinner has been compared to Roger Federer for his calm on-court demeanour and all-court movement. Federer himself has praised Sinner for the balance in his game, remarking, "What I like about him is that he almost has the same speed of shooting from the forehand and backhand." Former world No. 1 junior and tennis coach Claudio Pistolesi has praised Sinner's good lateral movement, which he attributes in part to Sinner's background in skiing. In this regard, Sinner has been compared to Novak Djokovic, who also credits a background in skiing for improving his tennis skills.
Sinner plays with contact lenses and has stated that he cannot even see the ball without them.

## Coaches and team

When Sinner began to prioritise tennis at age thirteen, he was coached by Riccardo Piatti, who had also been a part-time coach of Novak Djokovic and Milos Raonic. At the time, he also began working with Andrea Volpini and Massimo Sartori, the latter of whom was a longtime coach of Andreas Seppi. He continued to work with Piatti as his primary coach, and Volpini as his second coach. His team also consisted of physiotherapist Claudio Zimaglia and fitness coach Dalibor Sirola.
In February 2022, he ended his long collaboration with Piatti and his team and began to train with Simone Vagnozzi, ex-coach of Marco Cecchinato, new fitness coach Umberto Ferrara and physiotherapist. In July 2022, coach Darren Cahill officially joined Sinner's team. Instead of hiring a mental coach like other tennis players, Sinner uses Formula Medicine, an Italian mental training program developed for Formula 1 drivers. In early 2023, he hired Giacomo Naldi as his personal physiotherapist. In September 2024, he replaced Ferrara and Naldi with Novak Djokovic’s former fitness trainer Marco Panichi and physiotherapist Ulises Badio. He also works with osteopath Andrea Cipolla. Sinner's father, a chef, cooks for the team at major tournaments.

During the COVID-19 pandemic in 2020, Sinner launched his mental health initiative "What's Kept You Moving", a series in which he interviewed other young athletes about overcoming mental health challenges in sports. In 2022, Sinner became the face of the "An Ace for Research" initiative for cancer research, committing to a donation for the purchase of modern lasers to diagnose cancers in men for every ace he scored in the ATP Finals, and later visited the research laboratories at The Candiolo Cancer Institute.
He ventured into the investment world in 2022, diversifying his assets through four different companies that he registered in his place of residence, Monte Carlo. His real estate company owns properties at Corso Venezia in the historic centre of Milan.

### In the media and popular culture

Sinner’s nickname is The Fox, which inspired the design of his logo. A group of his Italian fans called the Carota Boys has garnered wide media attention for supporting him at major tournaments around the world dressed in carrot costumes.
Sinner has been the subject of incessant media attention in Italy and has been credited with the surge in the popularity of tennis in the country. It has been referred to as the Sinner Effect. Following his Davis Cup and Australian Open titles, Sinner was honored by the Prime Minister of Italy, Giorgia Meloni, in Chigi Palace in Rome and met with the President of Italy, Sergio Mattarella. Italy's Minister of Foreign Affairs, Antonio Tajani, appointed Sinner as Ambassador of Sports Diplomacy. Sinner subsequently declined an official invitation supported by the Prime Minister to appear at Italy's Sanremo Music Festival. The invitation caused controversy and public debate, with the president of The Italian Tennis Federation publicly advising Sinner against accepting it, stating that he must be protected from excessive media exposure and "should not be exploited". In June 2024, he received honorary citizenship of Sexten where he grew up. In Italy, Sinner has been labeled "the atypical Italian" by media outlets, a description he has agreed with.
During the 2023 Wimbledon, Sinner entered Centre Court carrying a monogrammed beige leather Gucci duffel bag, breaking Wimbledon’s all-white dress code, which made him the first tennis player to do so. The accessory prompted worldwide media coverage and commentary, with CNN pondering whether Sinner’s bag signals a shift in Wimbledon’s strict traditions.
In 2022, Sinner hosted Breaking Points, a video series created by GQ where he interviewed sports icons about mental health. In 2023, he was featured in GQ’s short film series A Hero’s Journey, released also as a podcast.
The Times has described Sinner as "the Gucci model with a shock of red hair and a surprisingly gangly frame".
On May 15, 2024, a book titled Diventare Sinner, written by Enzo Anderloni, Michelangelo Dell'Edera and Alessandro Mastroluca in collaboration with the Italian Tennis Federation was published by Giunti Editore. It follows Sinner’s evolution from a junior ski champion to a professional tennis player and grand slam champion.
In 2024, Forbes has named Sinner on their 30 Under 30 Europe list for 2024. In the same year, Time has named Sinner on their Time 100 Next list for 2024.

## Personal life

Sinner's first language is German. His Italian greatly improved after moving to Bordighera at the age of 13, and he also speaks English. Sinner resides in Monte Carlo in Monaco, where he moved at the age of 18.
One of his tennis idols is compatriot Andreas Seppi, who is also from South Tyrol. At age 17, Sinner stated that one of his goals was to "do better than [Seppi]".
