Big West Conference baseball tournament

In 1985, the Pacific Coast Athletic Association staged the Baseball Championship Series, a best-of-three championship at Pete Beiden Field in Fresno, California. The Fresno State Bulldogs, the regular season winners of the conference's north division, defeated the Cal State Fullerton Titans, south division winners, in two games. The conference did not renew the championship series for the next season.^[1]

In 1995, the Big West introduced a four-team double elimination tournament, with the first edition being won by the Cal State Fullerton Titans, eventual national champions that year. The iteration of the tournament lasted for four consecutive years, with two editions at Blair Field and two at Titan Field, and it was scrapped after the 1998 season.^[2]

The Big West reintroduced the tournament for the 2025 season, held at Goodwin Field (formerly Titan Field) and a rotating slate of venues in the years after. Anteater Ballpark will host in 2026 and Blair Field will host in 2027.^[3] They were the last major conference without a conference tournament.^[4]

The current iteration of the tournament see the top five finishers from the regular season seeded one through five based on conference winning percentage. Seeds No. 1, No. 2, and No. 3 received a bye into the double elimination bracket, while No. 4 and No. 5 battled in a single elimination the first round.
