Once his baseball career ended a second time, Bouton became one of the inventors of "Big League Chew", a shredded bubblegum designed to resemble chewing tobacco and sold in a tobacco-like pouch. He also co-authored "Strike Zone" (a baseball novel) and edited an anthology about managers, entitled "I Managed Good, But Boy Did They Play Bad" (published 1973). His most recent book is "Foul Ball" (published 2003), a non-fiction account of his attempt to save Wahconah Park, a historic minor league baseball stadium in Pittsfield, Massachusetts.
