Jannik Sinner: Italian’s doping case to be heard at Court of Arbitration for Sport in April 2025
Sinner twice tested positive for chlorosterol, a steroid used to build muscle mass, during last year’s Indian Wells tournament.
He did not dispute that traces of clotibol were found in a urine test and successfully argued that his physiotherapist had inadvertently contaminated the substance.
The International Tennis Integrity Agency (ITIA) acknowledged that Sinner had “no fault or negligence” and that he had provided a “credible” explanation.
WADA did not question the player’s explanation of why the substance ended up in his system, but found the independent panel’s conclusion that Sinner had no fault or negligence “was incorrect under the applicable rules”.
In 2024, the Italian had the best year of his career so far, winning the US Open and Melbourne Trophy.
He also won the season-ending ATP Finals and helped his country defend its Davis Cup title.
However, his doping case, along with that of five-time Grand Slam champion Iga Swiatek, has sparked discussion about how cases are handled within the tennis world.
Before the Cas date was announced, Sinner said: “I’d be lying if I told you I forgot about (the hearing).
“It’s something I’ve carried with me for a long time.
“But it is what it is.”
