So much of Andre Agassi’s life has been spent in the public eye - the various highs and lows, on and off the court, during his transformation from tennis brat to elder statesman - that it was possible to wonder how much more there was to be said about it all.

Plenty, it turns out. Excerpts of Agassi’s upcoming autobiography published by Sports Illustrated and the Times of London contain graphic depictions of his use of crystal meth, an account of how he wriggled his way out of a suspension by lying to the ATP Tour after failing a 1997 drug test, and the jarring contention that he always hated tennis “with a dark and secret passion” because of his overbearing father.

If image is indeed everything, as Agassi used to say to sell a sponsor’s cameras, he has provided new, indelible, behind-the-scenes images - along with raising questions about why he chose to reveal his crystal meth habit.

“Is it cathartic? I don’t know. I think it’s strictly from the heart. That’s the way he has operated in my view, going back to the latter portion of his playing career,” said Arlen Kantarian, who ran the U.S. Open from 2000-08. “I’m sure he feels good about getting it out on the table.”

Agassi, who won eight Grand Slam singles titles before retiring in 2006, is not explaining himself at the moment. His representative referred interview requests to his publishing company, which has set up a “60 Minutes” appearance on November 8, the day before the book’s scheduled release.

After an exhibition match on Sunday in China against long-time rival Pete Sampras, Agassi was asked if the book contains major revelations.

“I think I had to learn a lot about myself through the process,” Agassi said. “There was a lot that even surprised me. So to think that one won’t be surprised by it, it would be an understatement.

“Whatever revelations exist, you’ll get to see in full glory,” he added. “But the truth is, my hope is that somebody doesn’t just learn more about me, what it is I’ve been through, but somehow through those lessons, they can learn a lot about themselves. And I think it’s fair to say that they will.”

SI and the Times of London are among four publications that paid for the rights to print parts of Open: An Autobiography.

Excerpts from the book

Agassi calls his father “violent by nature,” and recalls being in the car when his father pointed a handgun at another driver.

He writes about making money by hustling people on tennis courts and remembers when, at 9 years old, he beat NFL great Jim Brown in a match to win a $500 bet for his father.

He poignantly recalls a telephone conversation with his father after winning Grand Slam title No. 1 at Wimbledon in 1992. Dad’s initial reaction? “You had no business losing that fourth set,” Agassi writes.

He writes about using crystal meth “a lot” and in sometimes-positive terms, including reference to “a tidal wave of euphoria that sweeps away every negative thought in my head. I’ve never felt so alive, so hopeful - and I’ve never felt such energy.”

“Apart from the buzz of getting high,” he says, “I get an undeniable satisfaction from harming myself and shortening my career,” he writes. “But the physical aftermath is hideous. After two days of being high, of not sleeping, I’m an alien. I have the audacity to wonder why I feel so rotten. I’m an athlete, my body should be able to handle this.”

Agassi says he wrote to the ATP Tour to explain the 1997 positive test and that “the central lie of the letter” was that he claimed he accidentally drank from a soda spiked with meth by his assistant “Slim.”

U.S. Fed Cup captain Mary Joe Fernandez, a former player who was a contemporary of Agassi’s, described the drug revelations as disappointing and “a bit of a shock.”

“It takes a lot of guts and courage to come out and say something that nobody would have really known about,” Fernandez said. “I’ve always admired Andre. He was a huge part of inspiring my generation, and he did a lot of great things and continues to do a lot of great things. He’s opening up now, and that’s his choice. Maybe people can learn from it and not make the same mistakes.”

“It fits in with the story arc of his redemption,” said Gene Grabowski, who guides high-profile figures through public relations crises.

“It’s going to make Andre Agassi even richer. This is going to help him sell his book, which is why he wrote it,” Grabowski said.

Agassi reportedly received at least $5 million for the book; the first printing is a half-million copies, a relatively high number in publishing.

“His book will probably sell. It seems very interesting, to say the least,” seven-time Grand Slam singles champion Venus Williams said.

Calling Agassi “an icon of his sport,” IOC president Jacques Rogge said, “If his admission would go together with the message to young athletes that it should not be repeated, then that would be useful.”

The International Tennis Federation said the reference to the 1997 drug test was surprising but noted that it did not oversee anti-doping efforts on the men’s tour back then. The ATP, which did, issued a statement on Wednesday about its rules, in general, noting an independent panel makes the final decision on a doping violation. Jim Fahey, president of the World Anti-Doping Agency, called on the ATP to “shed light on this allegation.”
