📌 Early life and background
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).
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 kg (77 lb). He also preferred competing in an individual sport directly against an opponent and having more control over the outcome. He moved to Bordighera on the Italian Riviera, Liguria, on his own 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 tennis training with Piatti full time, he had been playing only twice a week. He obtained his high school certificate at the Walther Institute, a private business and technical school in Bolzano.

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, the only junior event he played that year. 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 tested positive, twice, for the banned substance clostebol in 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. In August 2024, Sinner announced that he had parted ways with his fitness coach Umberto Ferrara and physio Giacomo Naldi. 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.
Sinner won his second major at the 2024 US Open, defeating 5th seed Daniil Medvedev in the quarterfinals, getting revenge for his previous Wimbledon loss, 25th seed Jack Draper in the semifinals, and 12th seed Taylor Fritz in the final.

Sinner then went on to win the championship against Novak Djokovic in straight sets to win his third ATP Masters 1000 title of the year, becoming the tournament’s youngest-ever champion, and seventh overall title of 2024. In November, Sinner won the season’s ATP Finals in Turin, Italy, by defeating Fritz. It was the first time since Ivan Lendl in 1986 in which a player won the trophy without losing any set, and the first time ever in which an Italian player won the title.
He ended the 2024 season by defeating Netherlands’ Tallon Griekspoor in the Davis Cup final, to win Italy’s second consecutive title. Sinner completed the entire season without a single straight-set defeat, becoming only the second man in the Open Era (Federer in 2005) to achieve this feat over a full year.
🔹 2025: Australian & Wimbledon singles titles, suspension
Entering the 2025 Australian Open as the defending champion, Sinner beat Nicolás Jarry, Tristan Schoolkate, Marcos Giron, Holger Rune, and Alex de Minaur on his way to the semifinals. In the semifinals, he defeated Ben Shelton in straight sets. He then defeated Alexander Zverev in straight sets to successfully defend his title in the championship match on 26 January.
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, including 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. Sinner’s lawyer Jamie Singer was vocal of the criticism, speaking out against what he said was ill-informed commentary about the process and the suspension itself.
Another point of contention was the seemingly favorable placement of Sinner’s suspension. Despite less than four months between the end of the 2025 Australian Open and the start of the 2025 French Open, Sinner’s 3-month suspension would not include any of the majors or any preceding “warm-up” tournaments. In May 2025, Sinner played his first tournament since his suspension at the Italian Open, a warm-up tournament for the upcoming French Open, where he reached the final. In doing so, he became the first Italian man to reach the final of the Italian Open since Adriano Panatta in 1978. This marked the second career clay court final for Sinner, and first since July 2022. Sinner was then defeated in the final by Carlos Alcaraz in straight sets. At the French Open, he reached the final without losing a set en route, including against Novak Djokovic in the semifinals. It was Sinner’s third career clay court final, all versus Carlos Alcaraz, and he was seeking his second clay court title, and first since July 2022. He faced Alcaraz in the final, and Sinner would take the first two sets before dropping the next two sets, which were nearly exact mirror images of the first two sets. In the fifth, decisive set, Sinner and Alcaraz would enter their third tiebreak of the match, and despite having held three championship points, Sinner would fall short to Alcaraz 2–10 in the super tiebreak. The 5-set final clocked in at 5 hours 29 minutes, making it the longest French Open final, shattering the previous record from the 1982 French Open, 4 hours 42 minutes.
Five weeks later, Sinner rebounded to win the Wimbledon Championships, defeating Alcaraz in four sets in the final. With the victory, he became the first Italian to win the Wimbledon singles championship. This was the second time Sinner faced Alcaraz on grass, the first being at the 2022 Wimbledon quarterfinals, winning both matches. After deciding to skip, like several other top players, the tournaments in Washington and Toronto due to the excessively congested calendar, Sinner reached the final of the Cincinnati Open, where he faced again Carlos Alcaraz, but retired before the end of the first set due to illness problems, having contracted a virus in the previous days.
In the following two weeks, he again reached the final of the US Open, playing his fifth consecutive major final, but was defeated in four sets by Carlos Alcaraz. He then reached the final of the ATP 500 in Beijing for the third consecutive time, winning in straight sets against the American Learner Tien and conquering his third title of the season. At the Shanghai Masters, Sinner had to retire in the third round against Tallon Griekspoor due to cramping. This would end his title defence in Shanghai. He then began his European indoor tour by winning the Vienna Open, defeating Alexander Zverev in the final in a three-set comeback match. It was his fourth title of the season. He finally won in the Paris Masters, where he defeated Canadian Felix Auger-Aliassime, without dropping a set during the tournament. He became the first Italian to win the tournament.
Sinner then successfully defended his title at the 2025 ATP Finals, winning all of his round-robin matches, defeating Alex de Minaur in the semifinals and defeating Alcaraz in the final, and not dropping a set during the tournament for the second year in a row, becoming the only player to win the finals without dropping a set for multiple years in a row, and suffering only one break in the entire tournament. Sinner also became the third player, after Federer and Djokovic, and the youngest, to reach the final of every major and the ATP Finals in the same season. This was Sinner’s 21st career hard-court title and 24th career Tour title, improving his finals record to 21–7 on hard-courts and 24–9 overall.

Afterwards, Sinner played at the 2026 Qatar ExxonMobil Open where he beat Tomáš Macháč and Alexei Popyrin to reach the quarterfinals. However, he suffered a shocking defeat to Jakub Menšík, making it the first time since 2024 that Sinner did not reach finals in back-to-back tournaments.
Sinner won his maiden Indian Wells title after defeating Daniil Medvedev in the final. He did not lose a set en route to the title, becoming the first man in history to win consecutive ATP Masters 1000 tournaments without losing a set.

At the Monte-Carlo Masters he extended his streak to 37 consecutive sets won in 1000 level tournaments.
Following the tournament, on 13 April 2026, Sinner regained the world No. 1 singles ranking from Alcaraz.

At the 2026 Madrid Open, Sinner defeated Alexander Zverev in the final. As a result, he became the first man to win the first four ATP Masters 1000 events of a season, as well as the first to win five consecutive 1000 level titles, since the series started in 1990, surpassing the record of four consecutive titles by Djokovic and Rafael Nadal.

Sinner’s loss ended a streak of nine consecutive major titles won between him and Alcaraz, dating back to the 2024 Australian Open, as well as a career-best winning streak of 30 matches. This marked the first time an incumbent world No. 1 failed to reach the third round of the French Open since Andre Agassi in 2000, and was the first time Sinner lost before the fourth round of a major since the 2023 French Open.
At the 2026 Wimbledon, Sinner began on a shaky note, down 2–1 in the first round, before coming back to win the final 2 sets against Miomir Kecmanović.

📌 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.
Following his loss at the 2025 US Open to Carlos Alcaraz, Jannik Sinner deliberately expanded his baseline-oriented playstyle during the 2026 season. He integrated more variety into his shot selection. He began incorporating backhand slices, drop shots, and defensive lobs to complement his trademark aggressive groundstrokes. Sinner significantly increased his frequency of approaching the net. During his successful 2026 Wimbledon title defence, he maintained a net-point conversion rate of over 80%, highlighted by winning 17 of 20 net approaches in his semifinal match against Novak Djokovic.
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.

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.
