In 1903, a small league in California defied Organized Baseball by adding teams in Portland and Seattle to become the strongest minor league of the twentieth century. Calling itself the Pacific Coast League, this outlaw association frequently outdrew its major league counterparts and continued to challenge the authority of Organized Baseball until the majors expanded into California in 1958.

The Pacific Coast League introduced the world to Joe, Vince and Dom DiMaggio, Paul and Lloyd Waner, Ted Williams, Tony Lazzeri, Lefty O’Doul, Mickey Cochrane, Bobby Doerr, and many other baseball stars, all of whom originally signed with PCL teams. This thorough history of the Pacific Coast League chronicles its foremost personalities, governance, and contentious relationship with the majors, proving that the history of the game involves far more than the happenings in the American and National leagues.
