Baseball commissioner Bowie Kuhn called "Ball Four" "detrimental to baseball," and tried to force Bouton to sign a statement saying that the book was completely fictional. Bouton refused to deny any of "Ball Four"'s revelations. Many of Bouton's teammates never forgave him for publicly airing what he had learned in private about their flaws and foibles. The book made Bouton unpopular with many players, coaches and officials on other teams as well, as they felt he had betrayed the long-standing rule: "What you see here, what you say here, what you do here, let it stay here." Pete Rose took to yelling "Fuck you, Shakespeare!" from the dugout whenever Bouton was pitching. Many of the day's sportswriters also denounced Bouton, with Dick Young leading the way, calling Bouton and Shecter "social lepers".
