The Pacific Coast League had emerged from the Depression of the 1930s in fairly good condition. There were four new ball parks: Seals Stadium in San Francisco in 1931, Lane Field in San Diego in 1936, Sick's Stadium in Seattle in 1938 and Gilmore Field in Hollywood in 1939. But after the attack on Pearl Harbor, there was some doubt that baseball would be allowed to operate during the war.

This work focuses on the 1942 to 1945 seasons offering final standings and details associated with the ballparks as well as the players. The appendix includes records of individual players listed by club and by year. The clubs are listed in order of finish.
