The beloved baseball classic now available in paperback, with a new prologue by Jim Bouton. When Ball Four was first published in 1970, it hit the sports world like a lightning bolt. Commissioners, executives, and players were shocked. Sportswriters called author Jim Bouton a traitor and social leper. Commissioner Bowie Kuhn tried to force him to declare the book untrue. Fans, however, loved the book. And serious critics called it an important social document. Today, Jim Bouton is still not invited to Oldtimer's Days at Yankee Stadium. But his landmark book is still being read by people who don't ordinarily follow baseball. For the updated edition of this historic book, Bouton has written a new prologue, detailing his perspective on how baseball has changed since the last edition was released.
