One day after World No. 1 Jannik Sinner won the Cincinnati Open, the International Tennis Integrity Agency announced that the Italian will not be banned after testing positive twice for an anabolic steroid back in March at Indian Wells.
At the tournament in March, Sinner tested positive for low levels of a metabolite of clostebol, but it was determined by the agency that the banned drug entered his system through a massage from his physiotherapist. The ITIA stated that they "determined a finding of No Fault or Negligence applied in the case, resulting in no period of ineligibility."
