WADA appeals, seeks ban after Sinner cleared in doping case

"WADA is seeking a period of ineligibility of between one and two years," it said in a statement, after the Italian twice tested positive for the banned substance clostebol in March but was cleared to carry on playing. The 23-year-old Sinner, who recently won the US Open for his second Grand Slam title and is currently in action in Beijing, has denied doping. Last month, the International Tennis Integrity Agency (ITIA) said that Sinner had been cleared of any wrongdoing after twice testing positive earlier in the season.
