Ramon Fernandez, who defied all his guard to unload 48 points, scored on a three-point shot, 99–103. Fabiosa came through with a pair of charities and Freddie Hubalde scored from under for a safe 107–101 lead with 23 ticks remaining.

Game 3
The Redmanizers were on their way to a 20-game sweep when they led by 13 points early in the third quarter. Sonny Jaworski, the focal point in the sideline incident between Don Pablo Carlos and coach Fort Acuña, was sent in the game by acting coach Carlos as the third quarter opened and the Big J welded the team together in its final thrust and with Ramon Fernandez and Arnie Tuadles pumping in the clutch hits, the Tamaraws finally got to turn the game around. Toyota was out front for the first time in the game, 75–73, in the first two minutes of the fourth quarter. After two ties and three lead changes, Crispa went up by five, 90–85. Ramon Fernandez and Abe King combined in a 10–0 run for a five-point Toyota margin, 95–90. Philip Cezar narrowed the gap but Fernandez again scored from the side for a 97–92 count. The last Crispa field goal was scored by Abet Guidaben, after which the Tamaraws ran the clock down. With 16 seconds left, the Redmanizers found itself with an opportunity to send the game into overtime, Philip Cezar committed a throw-in error and that turnover was what Toyota needed to put the game away as Crispa's winning streak was snapped.

Game 4
Crispa Redmanizers led by as much as 24 points in the second quarter and weathered the last-ditch stand by Toyota in the fourth quarter to prevail before a huge crowd turnout of 25,000 at the Big Dome. The Tamaraws managed to close the gap to within four points, 77–81, as the game moved into the homestretch, a 9–2 run by the Redmanizers behind Atoy Co, Freddie Hubalde, Joy Dionisio and Philip Cezar put them in front by 11 points, 90–79.
