In introducing Andre Agassi to a Palo Alto audience Friday, the moderator noted that the tennis star's autobiography recently hit No. 1 on the bestseller list.

Agassi smiled to the crowd at the Oshman Family Jewish Community Center.

"I finally did something my wife hasn't done," he said, referring to Steffi Graf, winner of 22 Grand Slam titles. "I can't stand it. I bring home a trophy and she brings home four."

Agassi likely will remain the literary leader in his own household. The famously private Graf has no plans for a tell-all — especially not loaded with blockbuster revelations like "Open."

The book chronicles his tumultuous childhood with a demanding father, Mike, and as well as Agassi's love-hate relationship with the sport that made him famous.

And, of course, there is the headline-making confession that he used the drug crystal meth and failed an ATP Tour drug test in 1997.

The confession has come at a price.

Martina Navratilova, among other critics, has blasted Agassi for lying to tournament officials.

Agassi responded Friday during a speaking engagement hosted by the Silicon Valley chapter of The Commonwealth Club.

"I understand her reaction. It's taken me years to process my own anger at myself," he said. "So to see someone else shocked or angered or disappointed doesn't surprise me."
