About the film
The Battered Bastards of Baseball is a 2014 documentary film about the Portland Mavericks, a defunct minor league baseball team in Portland, Oregon. They played five seasons in the Class A-Short Season Northwest League, from 1973 through 1977. Owned by actor Bing Russell, the Mavericks were an independent team, without the affiliation of a parent team in the major leagues.
The title is from a line in Jim Bouton's 1970 book Ball Four: "Us battered bastards of baseball are the biggest customers of the U.S. Post Office, forwarding-address department."
