Carl Tamayo and the Maroons take control in the third.
UP coach Goldwin Monteverde, though, remained dissatisfied particularly with the team's slow starts.
"We need to improve yung defense namin. I think they made 45 points noong first half," he said. "Habang nagpo-progress yung season, we need to work on that. I think yun pa rin, being consistent and not thinking about whatever standing we're at now. Ang importante is what to improve on pa rin going towards sa end ng season."
Jerom Lastimosa had 19 points, three rebounds, three assists, and three steals, but exited the game with a sprained right ankle with 5:33 left.
Cedrick Manzano had 10 points and three boards, as Joem Sabandal registered nine points, six assists, and three boards as the Soaring Falcons fell to a 3-5 card with their third loss in the last four outings.
