When Ball Four was published in 1970, it created a firestorm. Bouton was called a Judas, a Benedict Arnold, and a “social leper” for having violated the “sanctity of the clubhouse.” Baseball commissioner Bowie Kuhn tried to force Bouton to sign a statement saying the book wasn’t true. Ballplayers, most of whom hadn’t read it, denounced the book. It was even banned by a few libraries.
