ITIA bans Marketa Vondrousova four years over missed doping test

Former Wimbledon champion Marketa Vondrousova has been handed a four-year suspension after refusing to submit to an out-of-competition anti-doping test, officials said on Monday. The International Tennis Integrity Agency (ITIA) said the ban runs until June 21, 2030. The Czech player is 26.

According to the ruling, a doping control officer attempted to conduct the test at Vondrousova’s home last December, but she did not provide a sample. Vondrousova said the officer approached her door late in the evening and that she was scared because she felt proper identification and protocol were not followed.

An independent tribunal reviewed her explanation, along with testimony from the doping control officer, and concluded the evidence offered “no compelling justification” for refusing the test. Under anti-doping rules, a refusal to submit to sample collection can be treated as an anti-doping rule violation.

What the suspension means

The ITIA said Vondrousova is barred from playing in, coaching at, or attending any events organised or sanctioned by the International Tennis Federation (ITF), the WTA, the ATP, the Grand Slams, or any national association during the suspension period. The ban is scheduled to end on June 21, 2030.

ITIA chief executive Karen Moorhouse said the agency recognises the testing process can be uncomfortable, but described it as essential for protecting fair competition. She also said player and tester safety is a priority and that testers carry identification, while players can verify identity by other means if they are unsure.

Player background and possible appeal

Vondrousova won the Wimbledon women’s singles title in 2023 and reached a career-high No. 6 in the WTA rankings that year. The tribunal decision noted she was ranked No. 122 at the time of the ruling.

Her lawyer said Vondrousova will review the written decision before deciding whether to appeal to the Court of Arbitration for Sport (CAS). Any appeal would be handled under the sport’s established arbitration process.

The case comes as tennis continues to rely on out-of-competition testing, which requires players to provide daily whereabouts information so doping control officers can attempt tests during an allotted time window.

Attention will now turn to whether Vondrousova files an appeal and whether the sanction is modified or upheld ahead of the 2030 expiry date.
