Jannik Sinner expressed his confidence in avoiding a doping ban during a press conference ahead of the Shanghai Masters, addressing the ongoing appeal by the World Anti-Doping Agency (WADA) against him. WADA has contested a ruling from the International Tennis Integrity Agency, which found that Sinner had 'no fault or negligence' regarding two positive tests for clostebol, a prohibited anabolic steroid, in March. Sinner maintains that the positive results were due to contamination from a cream he used on a cut. The world No. 1 admitted he was 'surprised' by WADA's decision but emphasized his willingness to cooperate, as he had done previously. He expressed strong optimism about the outcome, stating he would be 'very surprised' if it turned out differently. Sinner is set to face Japan's Taro Daniel in the first round of the tournament on Saturday.
