Qualified to the Finals
Ateneo abandoned its game against the University of the Philippines (UP) with the Fighting Maroons leading 83–69 1:21 left in the game when a melee broke out involving Ateneo's Joseph Canlas and UP's Joseph Marata. The referees ejected Canlas after he tripped Marata, then the two players traded punches that led to a bench-clearing situation. An unidentified spectator fired a gun, who was escorted out of the Rizal Memorial Coliseum by UP baseball coach and police officer Boy Codiñera.
With the system currently in place, Ateneo would've forfeited the game and received no points (a loss under ordinary circumstances merited one point, two points for a win); however, Ateneo coach Fritz Gaston appealed the decision to the UAAP Board which was granted, ruling the game as an ordinary loss for Ateneo and giving them one point.
Ateneo clinched the twice-to-beat advantage in the elimination round finale which served as a de facto Game 1 of a best-of-3 series with a win against La Salle.
La Salle, led by Dindo Pumaren, had a ten-point advantage midway through the first half, 21–11. However, Ateneo caught up with them and kept the score close until the final deadlock at 66–all when Ateneo started an 8–2 run. Joseph Canlas scored four of Ateneo's eight points in the run, which ended with a Gilbert Reyes conversion off a steal from Joey Santa Maria. Pumaren closed the gap to four points at 74–70, with two free throws off Joseph Kenneth Nieto, but the Blue Eagles prevented further scoring opportunities for La Salle; Santa Maria fouled Daniel Francisco, who converted his two free-throws to give Ateneo the win, and a successful defense of their championship. Their back-to-back title run was their first successful title defense since the 1975 and 1976 NCAA seasons.
