Seals Stadium was a minor league baseball stadium on the west coast of the United States, located in San Francisco, California; it later became the first home of the major league San Francisco Giants. Opened in the Mission District in 1931, Seals Stadium was the longtime home of the San Francisco Seals (1931–57) of the Pacific Coast League. The PCL's Mission Reds (1931–37) shared the ballpark with the Seals for the first seven years, then moved to Los Angeles and became the Hollywood Stars.
