Defending champions UNLV defeated fourth-seeded Long Beach State in the final, 92–72, and captured their sixth PCAA/Big West championship. This was the Runnin' Rebels' sixth title in eight seasons.
There were no changes to the tournament format from 1989. All ten conference members participated in the field, with teams seeded in the bracket based on regular season conference records.
The top six seeds were given a bye into the quarterfinal round while the four lowest-seeded teams were placed into an initial preliminary round.
