All 11 MW schools were eligible to participate in the tournament. Teams were seeded by conference record. Ties were broken by record between the tied teams, followed by record against the regular-season champion, if necessary. As a result, the top five teams (Utah State, Nevada, Fresno State, San Diego State and UNLV) received byes into the tournament quarterfinals. The remaining teams will play in the first round. Tie-breaking procedures will remain unchanged from the 2018 tournament:
Head-to-head record between the tied teams
Record against the highest-seeded team not involved in the tie, going down through the seedings as necessary
