Background: Sinner’s Positive Test and Investigation
Jannik Sinner twice tested positive for clostebol, prompting the ITIA to investigate the case privately. The final verdict stated that Sinner did not knowingly or intentionally use a banned substance.
According to the official explanation, physio Giacomo Naldi applied an over-the-counter spray during treatment, unknowingly introducing the prohibited substance into Sinner’s system.
Kyrgios’ Initial Reaction
From the moment the case became public, Nick Kyrgios was one of the loudest voices calling for strict action.
He questioned the consistency of anti-doping procedures and accused authorities of giving Sinner preferential treatment.
When WADA later appealed the ITIA ruling and Sinner received a three-month ban, Kyrgios openly celebrated the decision.
Djokovic’s Comments on the Case
Last month, during an interview with Piers Morgan, Novak Djokovic weighed in on the controversy.
Djokovic noted that the doping issue would continue to “follow Sinner,” comparing it to how COVID-related scrutiny has followed him throughout his career.
Kyrgios Replies to Djokovic
Kyrgios was also interviewed by Morgan this week, where he addressed Djokovic’s remarks.
He stated:
-
His stance on the case has remained consistent.
-
Djokovic made an important point: regardless of intent, Sinner is responsible for what enters his body.
-
The overall handling of the situation “wasn’t a good look for the sport,” especially considering Sinner was the world No. 1 at the time.
Praise for Sinner’s Comeback
Despite his criticism of the case’s management, Kyrgios acknowledged Sinner’s impressive return to the court following his three-month ban.
He even predicted that the 24-year-old Italian could end up as “one of the greatest” in tennis history.
