Sinner claims innocence as ATP head confirms case 'run by the book'
World number one Jannik Sinner insists he has done nothing wrong after testing positive for clostebol, attributing it to a physio's spray. He was cleared by the International Tennis Integrity Agency, but WADA has appealed. ATP chairman Gaudenzi supports the process, dismissing claims of preferential treatment. Sinner remains focused on the Australian Open amid the ongoing case.
