Marketa Vondrousova receives four-year ban for refusing anti‑doping test
Czech tennis champion Marketa Vondroušová, the 2023 Wimbledon winner and former world No. 6, was handed a four‑year suspension by the International Tennis Integrity Agency (ITIA) after refusing an out‑of‑competition doping control at her Prague home on 3 December 2025. The player argued that the doping officer arrived outside her self‑reported 60‑minute testing window, that she felt unsafe, and cited the 2016 attack on fellow Czech Petra Kvitová as a reason for her anxiety. The independent tribunal rejected these explanations, stating that the refusal is punished as severely as a positive test and that the circumstances did not constitute a compelling justification.
The suspension runs from 22 June 2026 until 21 June 2030, and Vondroušová has 21 days to appeal the decision to the Court of Arbitration for Sport (CAS). Subsequent tests in December 2025 and May 2026 were negative for prohibited substances, but the ban remains in force. The ITIA’s detailed 58‑page report describes the officer’s arrival at 20:05, Vondroušová’s refusal to open the door, her vulgar WhatsApp messages to fellow player Andrew Paulson, and her eventual signing of a refusal form before leaving the premises. The player plans to challenge the ruling before the deadline.
