Italy’s Jannik Sinner has enjoyed the most successful – and eventful – season of his career, having dominated the men’s game while the case investigating his two failed doping tests rumbles on.
The reigning Australian Open and US Open champion, who won his seventh title of the season in Shanghai on Sunday, tested positive for clostebol in March.
An independent panel, which was presented the case by the International Tennis Integrity Agency (ITIA), accepted there was “no fault or negligence” attached to 23-year-old Sinner.
It said the world number one had provided a “credible” explanation and he was able to continue playing.
But the decision that Sinner bore no fault has been challenged by the World Anti-Doping Agency (Wada), which has launched an appeal to the Court of Arbitration for Sport (Cas).
No date has been set for the hearing.
“Whatever’s going to happen, I just wish for it to be resolved as soon as possible,” 24-time major champion Novak Djokovic said.
“This whole case is not helping our sport at all.”
