Seeding
The top six finishers from the regular season were seeded one through six based on conference winning percentage only. Only six teams participate, so Air Force was not in the field. New Mexico claimed the second seed over San Diego State by winning the season series. BYU claimed the fourth seed by winning the season series over Utah.| Team | W | L | Pct. | GB | Seed |
