The Lady Panthers never gave Iloilo's bet, Passi National High School a chance to win a set, 25-16, 25-15, 25-21.
They banked on strong spikers, Frika Verano and Ma. Teresa Caballero, who combined for 18 kills.
Passi tried to prolong the game behind the effort of Passi's team captain Cindy Optana, who scored 12 kills. But she missed her targets.

Monserrat earlier bowed down to reigning UAAP Champion University of the East, 25-18, 25-16, 25-22, behind Giza Yumang, one of the candidates for the League's MVP.
