The clause would ensure that future books are "positive in tone" and "do not breach the sanctity of our clubhouse," an unnamed Yankees official told Newsday in its Thursday editions.
Torre's book, "The Yankee Years," reveals that Yankees teammates called third baseman Alex Rodriguez "A-Fraud" in the clubhouse, and that he was viewed as having a "Single White Female" obsession with Derek Jeter. Torre also directly criticizes several players, including Carl Pavano and Gary Sheffield.
The Yankees have never before included a confidentiality agreement in the contract of a player or manager.
"Up to now, we have always operated our employer-employee relationships on a basis of trust," the Yankees official told Newsday. "But we never expected what we got from Joe. We may have to get a little tougher on this issue."
