All eyes were on Jannik Sinner at the US Open on Thursday as he made his first appearance on the practice courts in New York since the announcement that he had avoided a doping ban after successfully arguing two positive anti-doping tests had been the result of contamination.
On Tuesday, Sinner and the International Tennis Integrity Agency (ITIA) revealed that the player had twice tested positive for trace amounts of the banned substance clostebol from anti-doping test samples taken in March and an independent tribunal had subsequently determined that Sinner should bear no fault and not be deemed negligent for the failed tests.
