Marketa Vondrousova Appeals Four-Year Doping Ban to CAS
8/26/2026, 12:10:56 AM
Core Event: Appeal to the Court of Arbitration for Sport
The Czech former Wimbledon champion has lodged an appeal with the Court of Arbitration for Sport (CAS) against a four-year suspension imposed for refusing an out-of-competition anti-doping test at her home. CAS confirmed receipt of the appeal on August 25 and noted that a hearing date has not yet been set. The ban, issued in June, is scheduled to run until June 21, 2030.
Background & Context
In December 3, an International Tennis Integrity Agency (ITIA) anti-doping officer arrived at Vondrousova’s residence to conduct a scheduled test. The officer knocked at 8:15 p.m. (20:00) and, according to the player, failed to properly identify themselves or follow established protocol. Vondrousova declined to open the door, later signing a refusal form while walking her dog. An independent tribunal subsequently ruled that she provided “no compelling justification” for the refusal. Under anti-doping rules, players must maintain a daily one-hour whereabouts window for such tests.
Vondrousova, the 2023 Wimbledon champion and 2021 Olympic silver medalist, has not competed on the WTA Tour since skipping the Adelaide International in January due to a shoulder injury. Her world ranking has fallen from inside the top 50 to No. 153.

Criticism & Opposition
American world No. 3 Jessica Pegula described the punishment as “harsh,” contrasting it with the three-month ban accepted by Jannik Sinner in 2024 after a WADA agreement and the one-month sanction imposed on Iga Swiatek the same year. Pegula questioned the disparity in disciplinary outcomes, suggesting the rules were applied inconsistently.

- “I just don’t think that’s fair. I think the sentencing is so harsh,” — Jessica Pegula
- “So I don’t quite understand the difference between that and then obviously what happened with Sinner and Iga. They justified what the rules were and why it was the way it was,” — Jessica Pegula
What’s Next
CAS has not set a hearing date; the case is expected to be heard in the coming months, with a final ruling to follow several months thereafter. The outcome will determine whether Vondrousova’s suspension is upheld, reduced, or overturned.
