As reported in the Sydney Morning Herald Agassi says father gave him speed before match A SEQUEL to Andre Agassi's explosive drugs revelation has emerged in a second extract from his coming book, with the suggestion that his father, Mike, supplied amphetamines to Agassi before a match in a tournament in Chicago. German newspaper Bild has published a passage from the former tennis champion's memoir, Open, in which Phil Agassi warned his brother against taking the pills supplied by Mike Agassi, a former Iranian Olympic boxer. The suggestion is the substance was speed and Andre Agassi played while under its influence. The exchange is reproduced as follows: 'One night, Philly asked me to promise him something: ''Don't ever let Paps give you any pills to take.'' ''Pills?'' ''Next time you go to the nationals and Paps gives you pills, don't take them.'' ''He always gives me Exedrin, Philly. He gives me Exedrin before every match, because there's a load of caffeine in each one.'' ''Yeah, I know. But the pills I'm talking about are something else. They are really tiny, white and round. Don't swallow them, no matter what happens.'' ''Okay, but what kind of pills are they, Philly?'' ''Speed.'' As predicted by Philly, my father gives me a pill at the national tournament in Chicago. ''Hold out your hand,'' he said. ''This will help you. Swallow it.'' He puts a pill in my hand. Tiny. White. Round. I swallow it and I feel good. Not much different. A bit more alert …' In last week's book extract, Agassi admitted to taking crystal methamphetamine, or ''ice'', in 1997, and then lying to the ATP in an attempt to explain a positive test. Speed, too, is a stimulant banned under the World Anti-Doping Agency code administered by the International Tennis Federation, while caffeine - not prohibited since 2004 - remains on the monitoring list. In a separate development, David Howman, the director-general of WADA, told London's Sunday Telegraph he would be writing to the tennis authorities to ask them to investigate ''the possibility of perjury'' or ''a breach of the law'' following Agassi's admission he explained his positive test for crystal meth in 1997 by sending the ATP a signed letter claiming he had ''unwittingly'' taken the drug in a ''spiked soda''.
