Is there no penalty for a positive urine test? This is something that everyone has been more confused about in recent times, because there is currently one player who is immune to punishment, this player is Sinner, who has just won the United States Open tennis championship, Sinner is ranked No. 1 in the world, he is one of the best players in the world, but he has not been punished for two positive urine tests some time ago. Seeing this, everyone felt very speechless. I don't know why the ATP didn't make a decision to punish Sinner, is it because Sinner is the world No. 1? This is indeed unfair to other players, and I hope that the ATP can treat every player fairly, and not just focus on the results and fame of the players. If Sinner is not punished, even if Sinner surpasses Djokovic in the number of Grand Slam titles, it is estimated that it will be difficult for him to have a GOAT title in the world men's tennis.
