WADA Explains Discrepancy in Doping Bans: Sinner vs. Barquero Case Analysis
WADA clarifies the difference in doping bans between tennis star Jannik Sinner and figure skater Laura Barquero, citing evidence and case specifics.

The World Anti-Doping Agency (WADA) has recently addressed the public regarding the differing doping bans imposed on tennis player Jannik Sinner and figure skater Laura Barquero. Jannik Sinner, a top-ranked tennis player, received a three-month suspension, while Laura Barquero, a Spanish figure skater, was handed a six-year ban for similar doping violations involving the anabolic substance Clostebol.
The Cases at a Glance
- Jannik Sinner: Received a three-month ban after a settlement with WADA. His defense was that trace amounts of Clostebol in his system came from a massage administered by a trainer who had inadvertently contaminated the substance due to a cut finger.
- Laura Barquero: Given a six-year suspension after testing positive for Clostebol during the 2022 Winter Olympics and later in an out-of-competition test in January 2023. WADA deemed her explanation unconvincing, leaving the circumstances of the substance's entry into her system unclear.
WADA's Explanation
In an email to The Associated Press, WADA explained that the key difference between the two cases lies in the evidence supporting the athletes' explanations. For Sinner, the evidence clearly corroborated his account, whereas Barquero's explanation was inconsistent and unconvincing.
Public and Professional Reactions
Sinner's case has drawn criticism from some of his peers in the tennis world, questioning the leniency of his punishment compared to Barquero's severe six-year ban. Meanwhile, Barquero’s supporters have highlighted the apparent disparity in the two rulings.
Legal and Procedural Context
WADA initially sought a one-year ban for Sinner but later withdrew its appeal after accepting his explanation. In Barquero's case, a 'case resolution agreement' was signed by WADA, the International Skating Union (ISU), and Barquero herself, leading to the six-year suspension. WADA emphasized that Barquero had the option to contest the sanction before the Court of Arbitration for Sport (CAS).
Conclusion
The WADA’s detailed explanation underscores the importance of evidence and intent in doping cases. While both athletes faced similar accusations, the outcomes diverged significantly based on the facts and the credibility of their defenses.
