Nick Kyrgios has publicly criticized the handling of Jannik Sinner's doping case, where Sinner tested positive for the anabolic steroid clostebol twice in March but faced no punishment after an investigation deemed he bore 'no fault or negligence'. Despite Sinner's explanation that the substance entered his system through a physiotherapy spray, Kyrgios argues that the decision undermines the integrity of the sport and calls for a two-year suspension for Sinner. He highlights the disparity in treatment between high-profile players and others, citing examples like Simona Halep and Jenson Brooksby, who faced harsher consequences for doping violations. Kyrgios insists that he stands by his statements and vows to fight for fairness in anti-doping processes. Sinner has defended himself, asserting he is clean and that the quick resolution of his case was due to the clarity of the circumstances surrounding his positive tests. The controversy raises questions about the consistency of doping regulations in tennis.
