Czech Vondrousova appeals to CAS over four-year doping ban

Aug 25 : Former Wimbledon champion Marketa Vondrousova has appealed to the Court of Arbitration for Sport against her four-year ban for missing a doping test last year, the sport's highest judicial body said.Vondrousova was issued the suspension in June after the International Tennis Integrity Agency said the Czech did not submit her sample when notified by a doping control officer in an out-of-competition test attempt at her home in December.The 27-year-old said in April she had "reached a breaking point after months of physical and mental stress" and added that an officer arriving at 8:15 p.m. demanding an immediate test felt like a serious intrusion into her privacy.Vondrousova has said she never doped, and a test taken three days after the December 3 incident came back negative.
