Cal (39-10) takes flight to the Louisville Regional, where the Bears will play Jacksonville State (39-19) on Friday, May 20 at 2 p.m. PT. Host Louisville (36-18) and Illinois-Chicago (25-22) follow with a 4:30 p.m. PT match.

How Does This Work?

The Bears are one of 64 teams who will be competing at 16 regional sites in the first round double-elimination Regionals. The top 16 teams were seeded in order, and the remaining teams were placed in regional brackets to create balanced competition and avoid conference match-ups, when possible. The regional winners will advance to super regional competition for a best-of-three series at eight campus sites. The eight teams that win the Super Regionals will advance to the WCWS, an eight-team, double-elimination tournament. The championship final will be a best-of-three-series. The WCWS will be conducted June 2-8 at the ASA Hall of Fame Stadium in Oklahoma City.
