PacMan of boxing champion Manny Pacquiao and Coach Ramon Pido raced to a 16-point advantage in the second period, 43-27, behind enforcer Jaypee Locsin and Mindanao Division Most Valuable Player Louie Medalla.
M. Lhuillier then leaned on a nine-point explosion from guard Niño Ramirez to close in by halftime, 47-53.
With the momentum on their side, Woodrow Enriquez presided over M. Lhuillier's initial second half salvo, capped by a basket by Visayas Division MVP Jayford Rodriguez that gave them the lead for good with four minutes to go in the third canto, 65-64.
Mike Manigo then pushed the Jewelers further ahead entering the final quarter, 72-66. The Jewelers outscored PacMan in the pivotal third period, 25-13.
Manigo continued his heroics by pumping in two triples as part of a 10-2 opening run that gave the Jewelers of Coach Raul "Yayoy" Alcoseba their biggest lead of the game, 82-70.
PacMan would threaten for the last time, 83-86, on a Locsin basket with 3:50 to play.
Manigo and Enriquez eventually scored 10 markers each in the final quarter to preserve the win, M. Lhuillier's highest scoring output thus far in the five-month tournament supported by ML Kwarta Padala, Cokaliong Shipping Lines, Nature's Spring Drinking Water, Gameface.ph, Molten, Panasonic and Sulpicio Lines.
