The Toyota Tamaraws were the top qualifier in the Group A standings with nine wins and five losses in the All-Filipino Conference. The Tamaraws missed out a finals stint for the first time in seven conferences and settled for a third-place finish via 3–0 sweep off Tanduay.
In the Open Conference, the Tamaraws came up with the best imports seemingly - Bruce "Sky" King and John "Dr.I" Irving. Toyota wound up again with a 9-5 win-loss card after the two-round eliminations. In the semifinal round, Toyota forced a playoff game with arch rival Crispa for the second finals berth following a 104–92 victory, but fell short in the do-or-die game, 87–90. The Tamaraws clinch third place at the expense of Seven-Up.
Toyota came back with a vengeance in the Invitational championship, snapping Crispa's dynastic rule while claiming the league's first three-game title-romp. The visiting Emtex Sacronels (a guest team composed of players from the Brazil national basketball team, including Oscar Schmidt) had a clean seven-game sweep in the elimination round and sealed a titular meeting with the Tamaraws. King and Irving displayed an overwhelming show of power in Toyota's three-game sweep over the Brazilians. The championship was the first for coach Dante Silverio in the third conference.
