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 broke into the top 100, winning the Next Generation ATP Finals and the ATP Newcomer of the Year award. In 2021, he became the youngest ATP 500 champion at the Washington Open, and 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 the season by reaching the final of the ATP Finals and led 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, coming back from two sets down to win his first major title. He followed by winning the US Open and ATP Finals to finish the year as the dominant world No. 1.
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.[4][5] 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.[6] He has an older adopted brother named Mark, who was born in Russia.[7][8] 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.[9] 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.[10][11][12][13]
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.[14] When he resumed playing, he began working with Heribert Mayr as his first regular coach.[15] 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.[9] Nonetheless, tennis was still only his third priority behind skiing and football.[16][17] In the morning, he competed in a ski race, and in the afternoon, he played a football match for AFC Sexten (Youth).[9]
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 kilos.[9] He also preferred competing in an individual sport directly against an opponent and having more control over the outcome.[18][17] 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.[8][12][14] 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.[19][9] Before Sinner began training in tennis full-time with Piatti, he had been playing only twice a week.[16] He graduated from the Walther Institute, a private economics school in Bolzano.[9]
Sinner began playing on the ITF Junior Circuit, the premier junior tour which is run by the International Tennis Federation (ITF), in 2016. Despite 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.[20]
Sinner won his first ATP Challenger title in Bergamo in February 2019 at the age of 17 years and 6 months, despite entering the tournament with no match wins at the Challenger level. He became the first person born in 2001 to reach a Challenger final, and the youngest Italian to win a Challenger title in history. With the title, he rose over 200 spots in ATP rankings up to No. 324.[24][25]
During the second half of the season Sinner played more often on the ATP Tour than the Challenger Tour.[28] His first ATP Masters victory came at the Italian Open against Steve Johnson, and he broke into the top 200 with his next ATP win at the Croatia Open Umag in July.[23] The next month, he won a second ATP Challenger title in Lexington to become one of just eleven 17-year-olds to have won multiple Challenger titles.[29] After losing in qualifying at Wimbledon, Sinner qualified for his first Grand Slam main draw at the US Open.[30] He lost his debut match to No. 24 Stan Wawrinka.[28]
Sinner had a strong finish to the season. As a wild card at the European Open, he became the youngest player in five years to reach an ATP semifinal.[31] Along the way, he knocked off top seed and world No. 13 Gaël Monfils for his first career top 50 victory.[32] This performance helped him break into the top 100 for the first time one week later.[23] At the end of the season, Sinner qualified for the 2019 Next Gen ATP Finals as the Italian wild card and the lowest seed.[33] He won in his round robin group with victories over Frances Tiafoe and Mikael Ymer, losing only to Ugo Humbert.
After defeating Miomir Kecmanović in the semifinals, Sinner upset top seed and world No. 18 Alex de Minaur in straight sets to win the title.[34] He played one last event in Italy the following week, winning a third Challenger title in Ortisei. Sinner finished the year at world No. 78, becoming the youngest player in the year-end top 80 since Rafael Nadal in 2003.[26] He was also named ATP Newcomer of the Year.[35] and received the Gazzetta Sport Award for Best Performance of the Year for his win over de Minaur in the Next Gen ATP Finals.[36]
Following the ATP Tour shutdown due to the COVID-19 pandemic, Sinner had a successful restart to the season. Although he lost his opening round match to Karen Khachanov at the US Open, he fared better in Europe. He reached the third round at the Rome Masters, highlighted by a victory over world No. 6 Stefanos Tsitsipas.[38] He then progressed to become the youngest quarterfinalist at the French Open since Novak Djokovic in 2006, and the first to make the quarterfinals on debut since Rafael Nadal in 2005. During the tournament, he defeated Goffin again as well as US Open runner-up and world No. 7 Alexander Zverev before losing to Nadal.[39][40]
After a semifinal at the Cologne Championship, where he lost to Zverev,[41] Sinner closed out the season by winning the Sofia Open for his first ATP title. During the event, he defeated Next Gen rival Alex de Minaur and then Vasek Pospisil in the final.[42] He became the youngest Italian tour-level champion in the Open Era and the youngest player overall to win an ATP title since Kei Nishikori in 2008.[43][44]
Sinner carried over his success from late 2020 into the start of the 2021 season. He won his second career ATP title at the Great Ocean Road Open,[45] and notably defeated No. 20 Karen Khachanov in the semifinals after saving a match point.[46] He became the youngest to win back-to-back ATP titles since Rafael Nadal in 2005.[45] His ten-match winning streak came to an end in the first round of the 2021 Australian Open, where he lost a tight five-set match to world No. 12 Denis Shapovalov.[47]
Then at the French Open, his campaign was stopped short for the second year running by Rafael Nadal, who this time defeated Sinner in straight sets in the fourth round.[51] In his main draw debut at Wimbledon, he lost in the first round to Márton Fucsovics.
At the 2021 Citi Open in Washington, D.C., Sinner went into the tournament as the fifth seed and made it to the finals and beat several young players along the way such as Emil Ruusuvuori, Sebastian Korda, and Jenson Brooksby.[54] He beat Mackenzie McDonald in the final to win his third title and first ATP 500 title. Sinner was the first Italian finalist and champion in Washington's tournament history as well as the youngest ATP 500 and first teen champion since the category was created in 2009.[55] As a result, he entered the top 15 in the ATP rankings on 9 August 2021.
At the US Open, he defeated Gaël Monfils in the third round to reach the second week of a Major for the second time in the season. Sinner's tournament ended when he lost to Alexander Zverev in the 4th round in straight sets.
Sinner successfully defended his title at the Sofia Open as the top seed, defeating again second seed Gaël Monfils in the final.[56]
Sinner made his sixth career final at the 2021 European Open without dropping a set en route. He defeated Lorenzo Musetti, Arthur Rinderknech and Lloyd Harris to reach the final.[57] He bested Diego Schwartzman in the final to take his fifth career title. He became the youngest man to win five ATP titles since 19-year-old Novak Djokovic.[58]
On 1 November, Sinner became the first male player born in the 2000s to break into the top-10 after a semifinal appearance at the Vienna Open.
At the Rolex Paris Masters, Sinner received a bye in the first round but was defeated by Carlos Alcaraz. Because of this, Sinner was unable to directly qualify for the season-ending Nitto ATP Finals.[59]
At the ATP Finals in Turin, Sinner was present as the first alternate. Sinner entered the tournament after countryman Matteo Berrettini was forced to withdraw with an abdominal injury after his first match with Alexander Zverev.[60] He defeated Hubert Hurkacz and became the youngest player to win an ATP Finals match on debut since Lleyton Hewitt in Lisbon in 2000 and the first alternate to win a match since Janko Tipsarević in London in 2011.[61][62] Sinner played Daniil Medvedev next in the round robin stage, holding a match point before being defeated in 3 sets. As a result, he re-entered the top-10 in the rankings and finished the year at world No. 10 on 22 November 2021.
At the Australian Open Sinner reached the quarterfinals of a major for the second time in his career, becoming the fifth Italian man to reach that stage in Melbourne.[64] He then lost to fourth seed Stefanos Tsitsipas in straight sets.

He lost to top seed and eventual champion Novak Djokovic in five sets in the quarterfinals, after being two sets to love up.[75]
At the Croatia Open, Sinner defeated Carlos Alcaraz in the final to win his first clay court title.[76] In Montreal, he lost to eventual champion Pablo Carreño Busta in the third round.[77] Sinner's loss guaranteed a maiden Masters 1000 finalist from his half of the draw. At the Cincinnati Masters, he lost in the third round to Félix Auger-Aliassime after being up a set, a break, and 2 match points.[78]
Seeded 11th at the US Open, he reached the fourth round after defeating Brandon Nakashima in four sets.[79] Next, he defeated Ilya Ivashka in a five set match lasting close to four hours to reach the quarterfinals for the first time at this Major.[80] He became the youngest player to reach the quarterfinals of all four Grand Slam tournaments since Novak Djokovic in 2007–08.[81] He lost to Carlos Alcaraz in a five-set match that lasted 5 hours and 15 minutes; the match set the record as the latest finish (at 2:50 am EST) and second longest match in US Open history. Sinner held a match point while serving up 5–4 in the 4th set, but ended up losing the set 5–7.[82][83]
In September, during the Davis Cup Finals after Matteo Berrettini won his singles match against Argentina, Sinner won the second match (best of three matches) and thus secured a place for Italy's Davis Cup team at the Final 8 of the Davis Cup Finals.[84] Following close to a month break due to an injury sustained in the semifinal at the 2022 Sofia Open[85] he returned to the 2022 Erste Bank Open in Vienna and reached also the quarterfinals losing to top seed and eventual champion Daniil Medvedev.[86] In his next tournament, the 2022 Rolex Paris Masters, he lost in the first round to qualifier Marc-Andrea Huesler.[87]
Sinner finished the year ranked 15th in the world, one space ahead of countryman Matteo Berrettini.
Sinner then won his seventh title at the Open Sud de France in Montpellier, becoming the first player to win a tour-level title in the season without having dropped a single set and the first since countryman Lorenzo Musetti won the title in Naples in October 2022.[90]
At the ABN AMRO Open he defeated top seed and world No. 3 Stefanos Tsitsipas taking his revenge for the Australian Open loss, for his biggest win ever.[91] Next in the quarterfinals, he defeated Stan Wawrinka in straight sets.[92] In the semifinals, he defeated home favorite Tallon Griekspoor to reach the final,[93] which he lost to sixth seed Daniil Medvedev.
In March, he played in Indian Wells where he defeated Richard Gasquet, Adrian Mannarino, and Stan Wawrinka all in straight sets to advance to the quarterfinals where he faced defending champion Taylor Fritz and won in a three-set match. In the following round in the semifinals, he lost in straight sets to career rival and top seed Carlos Alcaraz who returned to world No. 1 following the tournament.[94] In Miami, he reached the quarterfinals of this tournament for a third straight year after defeating Grigor Dimitrov and Andrey Rublev, thus returning to the top 10 in the rankings at world No. 9.[95] He then defeated Emil Ruusuvuori to reach back-to-back semifinals,[96] where he again faced the defending champion Carlos Alcaraz, this time winning to reach his second Miami and career Masters final in three years,[97] putting an end to Alcaraz's hopes for a Sunshine Double and preventing him from returning to the No. 1 spot.[98] He lost to fourth seed Daniil Medvedev in straight sets in the final, extending his losing streak versus the Russian to 0–6.[99]
In Monte Carlo he reached a third consecutive Masters semifinal defeating compatriot and 16th seed Lorenzo Musetti.[100] At the French Open, Sinner was upset in the second round by Daniel Altmaier in a five-set match despite serving for the match in the fourth set and having two match points.[101] At five hours and 26 minutes, it was the longest match of Sinner's career up until this point and the fifth-longest in the tournament history[102] as well as the second longest of the season after Andy Murray against Thanasi Kokkinakis at the Australian Open.[103]
At the China Open, he defeated world No. 2 Carlos Alcaraz, his fourth tour-level win against the Spaniard, to reach his fifth final of the season, where he defeated world No. 3 Daniil Medvedev for the first time at the seventh time of asking.[107] As a result, he climbed to a career-high world No. 4 to become the second Italian in the history of the ATP rankings to reach the Top 5, equaling Adriano Panatta.[108] At the Shanghai Masters he lost in the round of 16 to Ben Shelton.[109] He recorded his 55th win over Andrey Rublev to reach his fourth ATP 500 career final in Vienna and became the first Italian man with the most wins for a season in the Open Era, surpassing Corrado Barazzutti's 54 mark in 1978.[110] He won the final defeating again top seed Daniil Medvedev to win his tenth ATP title, defeating him in two consecutive finals.[111]
On his debut at the ATP Finals, Sinner won all of his round-robin matches, notably beating the world No. 1 Novak Djokovic in a third set tiebreaker to clinch his fifth top-5 win in a row.[112][113] He ultimately lost in a rematch against Djokovic in the final.[114] He then made his debut in the Davis Cup, where he defeated Tallon Griekspoor in singles to help Italy win its quarterfinal tie against the Netherlands.[115] In the semifinal, Sinner faced Djokovic for the third time in 11 days, and become the first player to defeat him in a Davis Cup singles match since Juan Martín del Potro in 2011.[116] He saved three consecutive match points in the third set to become only the fourth player to beat Djokovic from match points down and the first one to do so with three in a row.[117][118] He also became only the third player ever to defeat Djokovic twice in 12 days, alongside Rafael Nadal and Andy Murray.[119] Sinner then teamed up with Lorenzo Sonego for the decisive doubles match, defeating Djokovic and Miomir Kecmanovic to clinch the tie and help Italy reach the Davis Cup final for the first time since 1998.[120] In the final, he defeated Australian Alex de Minaur to clinch the title for Italy for the second time after 47 years since 1976.[121] Sinner was awarded the Most Improved Player of the Year award and voted the Fans' Favorite at the 2023 ATP Awards,[122][123] while his coaches, Darren Cahill and Simone Vagnozzi, won the Coach of the Year award.[124] Sinner also received the award for Best Tennis Player at the Supertennis Awards.[125]
2024: Two majors and ATP finals titles, No. 1, sanctions
Sinner started his year at the Australian Open, where he beat Botic van de Zandschulp, Jesper de Jong, Sebastián Báez, Karen Khachanov and Andrey Rublev (all in straight sets) to reach his second major semifinal and first at the Australian Open. In the semifinals, he upset world No. 1 and defending champion Novak Djokovic to advance to his first major final, becoming the first player not to face a break point against Djokovic in a completed major match.[126] Sinner's victory over Djokovic was the latter's first defeat at the Australian Open since 2018.[127] Sinner became the first Italian player to reach the singles final at this major and the third man, after Adriano Panatta at the 1976 French Open and Matteo Berrettini at the 2021 Wimbledon Championships, to reach a major final in the Open Era.[128][129] In the final, he came from a two-set deficit to beat Daniil Medvedev to become the first Italian player, male or female, to win the Australian Open singles title, and the third man to win a Major (the second of which in the Open Era), and the first in 48 years.[130][131] His victory over Medvedev meant he became the second player to win the Australian Open after losing the first two sets in the final, after Rafael Nadal, who also beat Medvedev in 2022.
As the top seed at the Rotterdam Open, he recorded his 200th singles win in the quarterfinals, after Milos Raonic retired with a hip injury with Sinner leading by a set, becoming the first player born in the 2000s to accomplish this feat.[132][133][134] After defeating Tallon Griekspoor in the semifinal and Alex de Minaur in the final, Sinner rose to a new career high of No. 3 in the world, becoming the highest-ranked Italian player in history.[135] Sinner also became the first male player since Lleyton Hewitt, in 2001, to win his debut event as a major champion.[136] At the 2024 BNP Paribas Open, with a victory over 25th seed Jan-Lennard Struff to reach the fourth round, he recorded his 17th consecutive match win, the longest ATP level streak for an Italian player in the Open Era.[137] Sinner extended this to 19 consecutive wins (16–0 in 2024) by defeating Jiří Lehečka in the quarterfinal.[138] Prior to his semifinal defeat to Carlos Alcaraz, Sinner had won 36 of his previous 38 matches, dating back to the 2023 China Open.
Sinner's clay season saw his second defeat of the season, to Stefanos Tsitsipas at the Monte-Carlo Masters, in April. In May, Sinner withdrew from the Madrid Masters, at the quarterfinal stage, due to a hip injury.[143] Three days later, he withdrew from the Italian Open due to the same injury.[144] After Novak Djokovic withdrew from the 2024 French Open on 4 June, Sinner became world No. 1 for the first time on 10 June, following the conclusion of the tournament.[145][146][147] He became the first Italian player (male or female) to hold the top position in the rankings.[148] Sinner lost in the semifinal to Alcaraz in five sets.[149]
On 20 August, it was announced that Sinner received an anti-doping sanction and was stripped of his money and points from the Indian Wells tournament in March, due to testing positive for Clostebol, a banned anabolic steroid, but one that is legal and readily available over the counter in Italy.[158] The International Tennis Integrity Agency found that Sinner's physiotherapist, Giacomo Naldi, had used a spray containing Clostebol to treat a cut on his own finger, then proceeded to administer massages to Sinner's legs and feet without gloves, enabling trace amounts of Clostebol—less than one-billionth of a gram—to enter Sinner's system.[159][160] Sinner did not face further sanction after the ITIA found "no fault or negligence" on his part.[161][162][163]
Sinner won his second major at the 2024 US Open, defeating 5th seed Daniil Medvedev in the quarterfinals, getting revenge for the previous Wimbledon loss, 25th seed Jack Draper in the semifinals, and 12th seed Taylor Fritz in the final.[164] He became the fourth man in more than 50 years to win his first two major titles in the same season. At the post-match ceremony, Sinner dedicated his win to his aunt.[165]
At age 23, Sinner became the youngest man ever to win both hard-court majors in the same year. With his win and Aryna Sabalenka's win in the women's championships, it is the first time that the same man and the same woman won both hard-court majors in the same year (2024) since 1988.[166]
After defeating Tomáš Machač in the 2024 Shanghai Masters semi-final, Sinner was confirmed as the year-end world No.1, becoming the first Italian player in history to achieve this ranking.[170] Sinner then went on to win the championship against Novak Djokovic in straight sets to win his third Masters 1000 title of the year, becoming the tournament's youngest-ever champion, and seventh overall title of 2024.[171] In November, Sinner won the season's ATP Finals in Turin, Italy, by defeating Fritz.[172] 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.[172][173]
He ended the 2024 season by defeating Netherlands' Tallon Griekspoor in the Davis Cup final, to win Italy's second consecutive title.[174] 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.[175]
Jannik Sinner and Carlos Alcaraz have faced each other 10 times since 2021, with Alcaraz leading the rivalry at 6–4.[176][177] The duo have played several high-profile matches, such as the 2024 French Open semifinal, which Alcaraz won in five sets, the 2022 US Open quarterfinal, which Alcaraz won in five sets after saving a match point en route to the title,[178] and the 2023 Miami semifinal, won by Sinner. The pair met three times on the tour in 2024, with Alcaraz winning all three matches, notably their third meeting at the 2024 China Open.[169]
Jannik Sinner and Daniil Medvedev have met 15 times since 2020, with Sinner leading the rivalry 8–7. The rivalry used to be one-sided in favor of Medvedev, with the Russian winning their first six matches. Sinner disrupted this streak in late 2023 by winning the next five, and eventually leveling the head-to-head. The two have played a number of high-profile matches, most notably the 2024 Australian Open final, which Sinner won in five sets after being down two-sets-to-love to claim his first major title. They met again in the 2024 Wimbledon quarterfinals, which Medvedev won in five sets, and the 2024 US Open quarterfinal, which Sinner won in four sets en route to the title.[179]
Jannik Sinner and Novak Djokovic have met eight times with the rivalry tied at 4–4, with their first encounter coming in the 2021 Monte-Carlo Masters. Djokovic won their first three encounters, with Sinner recording his first win in the 2023 ATP Finals. The pair have played some notable matches, including the final of the 2023 ATP Finals, which Djokovic won,[180] the 2024 Australian Open semifinal, which Sinner won in four sets,[181] and the 2024 Shanghai Masters final, which Sinner won in straight sets.[182]
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).[183] His forehand is also a strength, owing to the fact he has a short compact takeback, meaning he rarely has to rush the shot, and the ability to rapidly open up his body, generating huge racket head speed and allowing him to hit the shot at over 160 km/h (100 mph) on occasion. He uses a modern, semi-western grip to generate large amounts of topspin, increasing net clearance and reducing the likelihood of unforced errors.[citation needed]
He also possesses a powerful first serve, which can reach speeds of up to 221 km/h (137.3 mph).[citation needed] He has changed his service stance, alternating between the pinpoint (legs together) and platform (legs apart) stances; as of late 2023 he serves with a pinpoint stance.[citation needed] Sinner is aiming to incorporate more variety into his game, hence he has been developing his net game and ability to serve-and-volley, as well as his slices and dropshots, to reduce the number of long rallies he has to play from the baseline.[citation needed]
Sinner has been compared to Roger Federer for his calm on-court demeanour and all-court movement.[11][14][19] 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".[13] 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.[184] In this regard, Sinner has been compared to Novak Djokovic, who also credits a background in skiing for improving his tennis skills.[185]
Sinner plays with contact lenses and has stated that he cannot even see the ball without them.[186]
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.[19] At the time, he also began working with Andrea Volpini and Massimo Sartori, the latter of whom was a longtime coach of Andreas Seppi.[187] 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.[17]
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.[18][188][189] In July 2022, coach Darren Cahill officially joined Sinner's team.[190] Instead of hiring a mental coach like other tennis players, Sinner uses Formula Medicine, an Italian mental training program developed for Formula 1 drivers.[191] In early 2023, he hired Giacomo Naldi as his personal physiotherapist.[192] 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.[193] Sinner's father, a chef, cooks for the team at major tournaments.[194]
At age 17, Sinner signed sponsorship deals with Nike and Head in 2019 for tennis footwear, apparel, and equipment.[195] In 2020, when he was eighteen years old and not yet in the top 50 of the ATP rankings, Sinner signed a global ambassador contract with Rolex.[196] In October that year, when he was ranked no. 46, he signed a sponsorship contract with Alfa Romeo.[197] In 2021, he signed with Intesa Sanpaolo. In 2022, Sinner signed a new $150 million sponsorship contract with Nike spanning ten years[198] and became the face of Gucci[199] and Lavazza.[195] In 2023, Sinner signed a partnership with Formula 1 to help attract young diverse audience to the motorsport.[200] In 2024, L’Oréal’s skincare brand La-Roche Posay appointed Sinner as their global brand advocate to help raise awareness about sun protection.[201] Some of his other sponsors include FASTWEB,[202]De Cecco,[203]Panini Comics,[204]Technogym,[205] Enervit,[206]Parmigiano Reggiano,[207] and Pigna.[208]
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.[209] 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.[210][211][212]
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.[213]
In 2022, Sinner released the comic bookPiccoli grandi campioni: Il manuale illustrato del tennis di Jannik Sinner through Panini Comics, an illustrated tennis manual for children in which an illustrated character of Sinner explains tennis and gives advice to beginners.[214]
In September 2024, Sinner was announced as the ambassador for the 2026 Winter Olympics volunteer program.[215]
Sinner’s nickname is The Fox, which inspired the design of his logo.[18][216] 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.[217][218]
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.[219][220] It has been referred to as the Sinner Effect.[221][222][223] 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.[224] 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".[225][226] In June 2024, he received honorary citizenship of Sexten where he grew up.[227] In Italy, Sinner has been labeled "the atypical Italian" by media outlets, a description he has agreed with.[228][229]
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.[230] The accessory prompted worldwide media coverage and commentary, with CNN pondering whether Sinner’s bag signals a shift in Wimbledon’s strict traditions.[231]
In 2022, Sinner hosted Breaking Points, a video series created by GQ where he interviewed sports icons about mental health.[232] In 2023, he was featured in GQ’s short film series A Hero’s Journey, released also as a podcast.[233][234]
The Times has described Sinner as "the Gucci model with a shock of red hair and a surprisingly gangly frame".[235]
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.[236][237]
Sinner's first language is German.[240] His Italian greatly improved after moving to Bordighera at the age of 13,[241][242] and he also speaks English.[243] Sinner resides in Monte Carlo in Monaco[8] where he moved at the age of 18.[244]
Sinner follows a healthy diet and has said he has never been to a bar or gone clubbing.[245][10] He declines to discuss his private life in interviews and avoids social media, deeming it "unhealthy", "dangerous" and "not real life".[229][246] He was in a relationship with Italian model Maria Braccini from 2020 to 2024.[247] As of June 2024, he was in a relationship with tennis player Anna Kalinskaya.[248]
