World No. 1 Jannik Sinner has been cleared of wrongdoing after failing two doping tests for the banned substance clostebol, with the International Tennis Integrity Agency (ITIA) ruling that he was not at fault as the substance entered his system unintentionally through a contaminated product used by his physiotherapist. This decision has drawn sharp criticism from fellow players Nick Kyrgios and Denis Shapovalov, who argue that Sinner should face a two-year suspension regardless of intent, highlighting perceived inconsistencies in doping regulations. Kyrgios voiced his outrage on social media, questioning the fairness of the ruling, while Shapovalov expressed sympathy for other players who have faced bans under similar circumstances. Despite the controversy, Sinner has stated he will move forward and comply with anti-doping regulations, while also forfeiting prize money and ranking points from the affected events. The debate continues to stir discussions in the tennis community as Sinner prepares for the upcoming US Open.
