WADA wants answers from tennis authorities

The head of the World Anti-Doping Agency, WADA, wants tennis authorities to shed light on Andre Agassi\'s admission that he used a banned drug and escaped a suspension by blaming his positive test on a spiked drink.



WADA president John Fahey says he was disappointed by the revelations in Agassi\'s upcoming autobiography that he used crystal methamphetamine in 1997 and lied to ATP tour officials to avoid a ban.



Agassi, an eight-time Grand Slam champion, writes in his autobiography \"Open\" that he was introduced to crystal meth by his assistant at a time when his form was falling and he was having doubts about his impending marriage to actress Brooke Shields.



In excerpts from the book published in The Times of London, Agassi says he was informed by the ATP later that year that he had tested positive for the drug and could face a three-month ban for use of a recreational substance.



He said he sent a letter to the ATP tour claiming he accidentally drank from a soda spiked with meth and asking for leniency.



Agassi said the ATP reviewed the case, accepted his explanation and threw it out.



Agassi, who married tennis star Steffi Graf eight years ago and has two children, retired in 2006.
