The International Tennis Integrity Agency has charged 2023 Wimbledon singles champion Marketa Vondrousova with refusing a doping test in December 2025. The Czech player cited mental health struggles and fear from a late-night visit by testers as reasons for her refusal. No provisional suspension has been imposed, allowing her to compete pending the outcome.
Marketa Vondrousova, the 26-year-old former world No. 6, faces a potential four-year ban after an incident on December 3, 2025, when doping control officers arrived at her home around 8:15 p.m., outside her scheduled testing window. Traumatized by years of hate messages, threats, and the 2016 home invasion of fellow Czech player Petra Kvitova, Vondrousova refused to open the door. Doctors later diagnosed her with an acute stress reaction and generalized anxiety disorder during the encounter, as she detailed in an Instagram statement Friday. She has not played singles since January due to a shoulder injury and described ongoing exhaustion from pressure and sleep issues. Vondrousova wrote, “Fear clouded my judgment, and I just couldn’t process the situation rationally.” A spokesperson for the ITIA confirmed the charge under the Tennis Anti-Doping Protocol but declined further comment, noting an investigation is underway with results expected soon. Her attorney, Dr. Jan Exner, vowed to contest the charge fully. “Marketa is a human being, not a machine,” he said, emphasizing protocol failures by testers and her documented stresses. Exner anticipates vindication before summer. Though free to play, Vondrousova announced a break to prioritize mental health, likely missing the Madrid Open starting April 20 after recent Billie Jean King Cup doubles duty.
