History

Historical Context

March 2016 Maria Sharapova tested positive for meldonium—added to WADA’s banned list on 1 January 2016—and received a two-year ITF ban that the Court of Arbitration for Sport reduced to 15 months. That ruling guided the response to Markéta Vondroušová’s 2025 refusal of an out-of-competition test, which earned a four-year suspension and criticism from Jessica Pegula and Jannik Sinner, highlighting CAS’s ongoing role in tennis anti-doping policy.
