BYU defeated rival Utah in the championship game, 51–49, to clinch their first WAC men's tournament championship.

Format

The tournament field remained fixed at nine teams, and teams were again seeded based on regular season conference records. All teams were entered into the quarterfinal round with the exception of the two lowest-seeded teams, who played in the preliminary first round to determine who would then play against the tournament's top seed.
