WADA want answers from ATP over Agassi

Andre Agassi has admitted his life has veered close to "catastrophe" more than once as anti-doping chiefs urged tennis authorities to explain why the American avoided a drugs suspension.

Agassi's revelation that he used crystal meth during 1997, the worst year of his career when he slumped to 141st in the world rankings, was followed by his explanation of how he skipped a ban after failing a test.

He wrote a letter protesting his innocence, and detailing how crystal meth came to be in his system because he drank a friend's spiked drink. Agassi was spared punishment.

In his autobiography, Agassi admits that his story was a lie, and the World Anti Doping Agency are urging the ATP to explain the circumstances behind Agassi being let off.

WADA president John Fahey said: "We would expect the ATP, which administered its own anti-doping programme at that time, to shed light on this allegation."

Agassi, now 39, explained the rationale behind telling all, three years after retiring from the sport.

"I was brutally honest about myself," he said.

"I detailed my misguided rebellions, my frustrations and distractions, and bad decision which in a few instances almost ended in catastrophe.

"I wasn't keen on embarrassing myself, but I felt that my story was one from which many people could learn."
