Big West Conference

The Big West Conference was formed as the Pacific Coast Athletic Association on July 1, 1969. Cal State LA, Fresno State, Long Beach State and San Diego State University were joined by San Jose State University, UC Santa Barbara and University of the Pacific in the original line-up. In 1974, Cal State Fullerton moved into the conference. By 1977, UC Irvine joined the conference and UCSB was back in while Utah State University became the first non-California member of the circuit, transforming the PCAA into a regional conference. UNLV (1981) and New Mexico State University (1984) soon followed suit, bringing the league's membership to 10 universities. The PCAA began its 20th year of existence in 1988 by changing its name to the Big West Conference.

From 1977 to 1984 the conference's teams played in two different conferences for their baseball season. Half the teams played in the Northern California Baseball Association, while the others were in the Southern California Baseball Association.

Long Beach State and UC Santa Barbara are the conference's longest tenured members, both being original charter institutions. Long Beach State is the only school that has held membership every year in the conference since its inaugural season in 1969, with UC Santa Barbara leavng the conference for two years in the 1970s. Cal State Northridge and UC Riverside joined the conference in 2001-02. In 2013, the University of Hawaii would join the Big West, followed by both; Cal State Bakersfield and UC San Diego for the 2021 season.

University of Hawaii and UC Davis are planning to join the Mountain West Conference after the 2026 baseball season. California Baptist University, Utah Valley University, & California State University, Sacramento are slated to join the Big West in the 2026-2027 school year. UC San Diego and UC Santa Barbara are slated to leave the Big West following the 2026-2027 school year for the West Coast Conference.
