Alex Compton and Eric dela Cuesta each fired 15 points while Ken Bono added 13 but it was Al Magpayos clutch shooting that carried the Jewels past the Snack Masters for their second straight victory.
Magpayo scored five of his 11 points in the final quarter, including a crucial triple in the stretch that secured the win for the Jewels while dealing the Snack Masters their first loss in two starts.
Magpayo, an ex-pro, was 0-of-6 before sinking that crucial trey.
"The reason why were here is to win, nothing personal," said Montana interim coach Nel Parado, alluding to the grudge match with Granny Goose coach Robert Sison.
Earlier, Heroes Cup champion Magnolia Ice Cream drew big games from Kelly Williams and Arwind Santos as it waylaid Teletech, 57-46, to even its record to 1-1.
Williams, the finals MVP last conference, dished out a double-double job with 22 points and 18 rebounds while Santos had nine points, 11 rebounds and three shot blocks that erased the stigma of the Spinners sorry 55-64 loss to the Snack Masters.
"All the guys came out with their A-game. Our earlier loss was really a wake-up call for us," said Magnolia coach Koy Banal.
Former pro Nino Gelig fired 16 points but it wasnt enough to prevent the Jerry Codiñera-mentored Titans from absorbing their second straight setback.
Down, 46-47, early in the last canto, the Jewels held the Snack Masters scoreless while scoring six points of their own to take a 52-47 advantage.
