After only seven seasons, UC San Diego’s time in the Big West is coming to an end. UCSD will join the West Coast Conference for the 2027-28 season, as first reported by Jon Rothstein of CBS Sports on Tuesday morning, Sept. 2. The shocking news comes after the Tritons’ first year of Division-I postseason eligibility, which saw both UCSD men’s and women’s basketball teams win their respective Big West Championships. The WCC does not sponsor six UCSD sports currently participating in the Big West: men’s volleyball, women’s water polo, men’s and women’s swimming, and men’s and women’s track and field. Other Triton sports not sponsored by the Big West nor the WCC, such as fencing, already participate in other conferences.
