Jannik’s summit to the top of the world tennis has been nothing short of extraordinary over the past twelve months. This time last year in Beijing, Jannik’s career would dramatically change after many tennis fans suggested that an incident in which he threw up inside a bin during a match against Grigor Dimitrov began his rise to number one. Consequently, not only would “post-puke Sinner” be born, but Jannik would go on to win that title in Beijing and start a twelve-month tear throughout the entire ATP tour. After two grand slam titles, becoming Italy’s first ever World Number one and creating new exhilarating rivalries with the great Novak Djokovic and two-time Wimbledon Champion Carlos Alcaraz, the 2024 season has been by far the best of Jannik’s young career so far. But as the tennis season this year begins to reach its twilight, it was the event in Beijing in 2024 where Jannik Sinner’s career would be hit with a different kind of shockwave. 

“This recent appeal has the potential to cause huge ripple effects throughout the tennis world…”

Midway through his last-16 match against Roman Safiullin at the China Open in Beijing, the World Number One as well as the entire sporting world learnt of the news that a potential doping ban could be heading the Italian’s way. The World Anti-Doping Agency (WADA) announced it would intend to appeal a decision made by the International Tennis Integrity Agency (ITIA) back in August over Jannik Sinner’s positive test at Indian Wells in March for the performance enhancing steroid Clostebol. Jannik was cleared by the ITIA of any wrongdoing for the incident due to them ruling that Sinner was unintentionally contaminated with the drug by his physiotherapist Giacomo Naldi. The ITIA ruled that Nardi had used a spray containing the steroid, unaware of its performance enhancing affects. This decision enabled Sinner to play both in the months after his positive test but also in the weeks after the decision in August, where he would go onto win the US Open amid much public backlash against the ruling. 

“Not only could this put Jannik’s titles under question, but also the integrity of the ITIA as an organisation.”

However, this recent appeal has the potential to cause huge ripple effects throughout the tennis world. WADA stated, “It is WADA’s view that the finding of ‘no fault or negligence’ [from the ITIA] was not correct under the applicable rules.” WADA intends to take this decision to the Court of Arbitration for Sport (CAS) and if successful, WADA’s appeal could hit Jannik with a possible ban of between 1-2 years. Not only could this put Jannik’s titles under question, but also the integrity of the ITIA as an organisation. In response to the appeal, Jannik stated he was, “surprised of this appeal because we had three hearings. All three hearings came out very positively for me.” 

“Questions will be asked whether tennis is correctly equipped to deal with doping allegations…”

Therefore, with the ITIA and WADA holding such different views on the situation, does the system need to be changed? As Novak Djokovic argued in a press conference before the Shanghai Masters that, “there is a lot of issues in the system” and argued that “we see a lack of standardised and clear protocols.” This comes under the gaze of an incident involving British WTA player Tara Moore, who was provisionally suspended for 19 months from May 2022 whilst an investigation took place after her testing positive for traces of an anabolic steroid called Boldenone. As a result, questions will be asked whether tennis is correctly equipped to deal with doping allegations and whether the ITIA and tennis wants to treat players at the top of the professional game in the same way as it does with players of a lower ranking. 

Therefore, whether Sinner gets banned or not, the eventual decision CAS decides to make in response to WADA’s appeal will undoubtedly have huge ramifications on the future of the game. Will there forever be an Asterix against Jannik’s US open title? Can the ATP cope with the possible loss of its number one? Does tennis have an integrity problem? These questions may soon have their answers.
