Compton scattered seven of his 15 points in the fourth quarter as the Jewels held off the Tortillos to claim their fifth win against four losses in a tie for third with the Hapee-PCU Teeth Sparklers.
But it was Ken Bono, who keyed Montana’s fiery start as he exploded for 10 points in the first quarter and went on to finish with a career-high 18-point performance.
"Ken (Bono) was just great today, he really stepped up for us," said Montana coach Robert Sison.
The Tortillos actually came to within five at 50-55 but Compton came through with two jumpers — one from the right baseline and the other from the right flank to seal the win.
The Joe Lipa-mentored Tortillos slid to a share of fifth place with the Harbour Centre Port Masters on 5-5 (win-loss) records but still remained in the hunt for a semis slot.
Earlier, Rain or Shine outgunned Far Eastern Insurance, 83-75, to likewise inch closer to the semifinals with six wins in nine outings.
