The Fuel Masters took the lead for good at the end of the third quarter on a halfcourt three by LA Revilla, turning the momentum in Phoenix's favor before Calvin Abueva and Matthew Wright finished off the Elite.
Phoenix finished with an 8-3 (win-loss) record to clinch second spot behind Ginebra - the best elimination-round placing in the franchise’s young two-year history.
Ginebra also clinched the top seed owing to Phoenix’s win over Blackwater.
Blackwater slipped to 7-4 and ended the eliminations as the fifth seed. The Elite will now take on fourth-seed Magnolia in the round of eight.
Abueva finished with 25 points and eight rebounds while Matthew Wright added 23 points, including a clutch two-pointer with 41.8 seconds left in the fourth to secure the win for Phoenix.
Eugene Phelps had 16 points and 19 rebounds for Phoenix.
The Fuel Masters never let go of the lead and Abueva’s jumper with 2:22 left in the fourth quarter capped a 6-0 run that gave the team a 93-84 lead.
Phoenix was able to win after trailing by nine points in the contest.
“Maraming easy baskets nung first half, inaatake ‘yung mga guards namin. I told them na you have to take pride in your defense,” said Phoenix coach Louie Alas.
“I told them that for us to go to the next level, we need to make multiple stops at every possession,” he added.
Henry Walker scored 21 points while Nard Pinto had 17 points and 10 assists for Blackwater, which lost Mike DiGregorio after he was ejected for throwing the ball at Phelps in the second quarter.
