World number one Jannik Sinner is set to confront doping allegations at the Court of Arbitration for Sport (CAS) on April 16-17, 2025. This hearing follows an appeal by the World Anti-Doping Agency (WADA) after the International Tennis Integrity Agency (ITIA) initially cleared Sinner of wrongdoing. The controversy arose after Sinner tested positive for the banned steroid clostebol in March 2024. The hearing will be held privately, as no parties requested a public session.
Sinner, who concluded 2024 with two Grand Slam titles—Australian Open and US Open—has maintained a remarkable record of 73 wins out of 79 matches. Despite the ongoing doping case, he is preparing to defend his title at the Australian Open, where he faces Chilean player Nicolas Jarry in the first round. Sinner expressed that the doping allegations linger in his mind, yet he remains focused on performing at the highest level.
As the situation unfolds, Sinner's future in the sport hangs in the balance. The potential for a significant suspension looms, with WADA's request indicating a range from one to two years. However, previous cases involving accidental doping have provided a glimmer of hope for Sinner. His legal team is optimistic, citing the minimal quantity of the substance found and the support from independent bodies that have cleared him.
In 2024, Sinner amassed earnings of approximately €21.5 million, underscoring his status as a top competitor in tennis. As he approaches the new season, Sinner aims to continue his dominance and solidify his position at the pinnacle of the ATP ranking.
