Nick Kyrgios has caused a serious stir with his tweet straight after Jannik Sinner won Wimbledon

Nick Kyrgios has ignited a firestorm of debate with a cryptic tweet posted immediately after Jannik Sinner’s Wimbledon 2025 triumph on July 13. The Australian, sidelined from competitive play due to injuries, sent a single asterisk (*) to his X followers moments after Sinner defeated Carlos Alcaraz 4-6, 6-4, 6-4, 6-4 to claim his first Wimbledon title and fourth Grand Slam. The ambiguous symbol has been widely interpreted as a jab at Sinner’s past doping controversy, reigniting tensions in the tennis world.

Sinner served a three-month ban earlier in 2025 after testing positive for clostebol in 2024, a case he attributed to unintentional contamination from a medical spray used by his team. The International Tennis Integrity Agency cleared him of intentional doping, but the lenient penalty drew criticism, notably from Kyrgios, who in February called it a “sad day for tennis” and questioned the fairness of the sport’s anti-doping system. His latest tweet appears to suggest that Sinner’s victory carries an asterisk—implying it’s tainted—echoing his earlier stance.

The reaction has been polarized. Some fans on X praised Kyrgios for highlighting perceived inconsistencies, while others slammed him as jealous, pointing to his lack of Grand Slam titles and past controversies, including a 2023 domestic abuse case. Sinner, meanwhile, celebrated his win with humility, thanking Alcaraz and his team, seemingly unbothered by the backlash. The stir underscores ongoing debates about doping in tennis, with Kyrgios’ bold move amplifying scrutiny on Sinner’s achievement.
