Tennis star Rafael Nadal, tired of being dogged by doping accusations, has requested that the International Tennis Federation make all his drug-testing results public.
Nadal made the request in a letter to ITF president David Haggerty on Monday, the same day he filed a defamation suit against Roselyne Bachelot, France's former minister for health and sport, for comments that suggested he had been doping.
"I know how many times I am tested, on and off competition," Nadal wrote in the letter obtained by the Associated Press. "Please make all my information public. Please make public my biological passport, my complete history of anti-doping controls and tests."
Nadal went on to request that the ITF "start filing lawsuits if there is any misinformation spread by anyone."
The ITF said that Nadal has the right to make his test results publicly available.
"The ITF can confirm that Mr. Nadal has never failed a test under the (Tennis Anti-Doping Program) and has not been suspended at any time for an anti-doping rule violation or for any other reason related to the TADP," the ITF said in a statement sent to the Associated Press.
Nadal's suit against Bachelot stems from comments she made on a French television show last month. Bachelot suggested Nadal's seven-month injury absence in 2012 was "probably due to a positive doping test."
"It is unacceptable and mostly unfair that someone that should have knowledge of sports to a certain point and degree can publicly say something like this with no proof or evidence," Nadal wrote in the letter.
Nadal's strong anti-doping stance comes three months after women's tennis player Maria Sharapova failed a drug taken for the banned substance meldonium at the Australian Open. Sharapova was provisionally suspended on March 8 and has an upcoming hearing with the ITF.
Nadal won his 49th clay-court tournament on Sunday to match the record set by Hall of Famer Guillermo Vilas, who finished his career in 1992.
