Men’s tennis world No. 1 Jannik Sinner faced questions during his US Open media availability regarding his recent positive drug tests for Clostebol, an anabolic steroid. The International Tennis Integrity Agency stated that Sinner bore no fault or negligence despite testing positive for the substance at low levels in samples collected in March.
Sinner, the top seed at the US Open, emphasized that he had not intentionally violated any anti-doping rules and attributed the positive tests to inadvertent contamination through treatment from his physiotherapist. He announced that he had parted ways with his physiotherapist and fitness coach due to the incident.
