Barry Bonds' lawyer plans to sue the authors and publisher of a book alleging the outfielder used steroids, a newspaper reported Thursday. Bonds' attorney, Michael Rains, sent a letter to the agent for the authors of "Game of Shadows" informing them of his plans to sue the writers, publisher Gotham Books, the San Francisco Chronicle and Sports Illustrated, which published excerpts earlier this month. The book, released Thursday, was written by Mark Fainaru-Wada and Lance Williams, both Chronicle reporters. It claims Bonds used an array of performance-enhancing drugs, including steroids, human growth hormone and insulin, for at least five seasons beginning in 1998. The Chronicle reported Thursday on its Web site that that Rains will ask a judge Friday to issue a temporary restraining order forfeiting all profits from publication and distribution. Rains said he will file the suit under California's unfair competition law. The letter does not describe the basis of the suit. Williams told The Associated Press Thursday that the book will stand up to a court challenge. "I don't know what the legal action they contemplate is," he said. "Gotham can speak to the legal issues but the facts in our book are true and they will stand up to scrutiny."
