Seeds

Of the 11 conference teams, 10 were eligible for the tournament. UC San Diego was ineligible for this year's tournament, as they were in the first year of the four-year transition required for teams transferring to Division I from Division II. Teams were seeded by record within the conference, with a tiebreaker system to seed teams with identical conference records. Unlike previous years, reseeding teams after the quarterfinals did not take place for this year's tournament.
