World No. 1 in men's professional tennis (ATP) singles, Yannick Sinner (Italy), has been suspended from competition for three months until early May due to a positive doping test.

The AP news agency reported that the World Anti-Doping Agency (WADA) has decided to suspend Sinner from competition for three months until May 5 due to his positive doping test.

Sinner has won three major singles titles, including the Australian Open, US Open, and this year's Australian Open. However, he tested positive for doping in March of last year, and the International Tennis Integrity Agency (ITIA) accepted Sinner's claim that there was no intentionality and concluded the case without a suspension.

WADA filed a lawsuit with the Court of Arbitration for Sport (CAS) in September of last year, claiming that Sinner needed to be suspended, and Sinner was scheduled to appear at CAS in April to explain his position. However, as WADA and Sinner effectively agreed on a three-month suspension, the CAS lawsuit was dropped.

This disciplinary action will allow Sinner to compete in the second major tournament of the season, the French Open, which begins at the end of May.

However, there is much criticism that this ruling on Sinner is 'lenient'. Stan Wawrinka (Switzerland), who has won three major singles titles, lamented on his social media that "it is no longer possible to believe in the words clean sport," and Daniil Medvedev (Russia), the 2021 US Open men's singles champion, said in an interview after the French Open that "from now on, anyone (who tests positive for doping) can just explain to WADA like Sinner." Nick Kyrgios (Australia), known as the 'bad boy of the court', also wrote on social media, "All the win records and prize money remain the same, can this be called a disciplinary action?" and "A sad day for tennis."
