Jannik Sinner, the 22-year-old Italian tennis player, has been handed a three-month ban by the World Anti-Doping Agency (Wada) after testing positive for clostebol, a banned anabolic steroid. The ban comes as Sinner was preparing to compete in the Qatar Open, and it has sparked controversy in the tennis world. Some players, including Novak Djokovic, have questioned the fairness of the punishment, suggesting that Sinner has received preferential treatment due to his status as the world's number one player. Others have criticized the timing of the ban, which allows Sinner to return to competition just before the French Open, a Grand Slam tournament. Sinner's team has maintained that he did not intentionally take the banned substance, and that it was inadvertently ingested through a massage cream used by his physio. The case has raised questions about the effectiveness of the anti-doping system in tennis and the consistency of punishments for players who test positive for banned substances.
