Former Wimbledon champion Markéta Vondrousová has been handed a four-year suspension from professional tennis after refusing to submit to a doping test in December. The decision was announced by the International Tennis Integrity Agency (ITIA). The incident occurred during a doping control attempt, leading to the sanction. Vondrousová, age 26, achieved a career high by winning the Wimbledon title in 2023. Her last competitive appearance was at the Adelaide tournament earlier this year. The length of the suspension effectively sidelines her from major competitions for a significant period. The ITIA is responsible for safeguarding the integrity of professional tennis.
