Phoenix Super LPG made just enough free throws in the end game to beat TNT Tropang Giga 91-88 and keep its winning streak alive in the Commissioner's Cup at Ynares Center-Antipolo on Sunday.

The Fuel Masters, who led by as many as 17 points in the first half before TNT made it a game, upped their record to 5-3 for solo fourth in the standings.

TNT, meanwhile, fell to 3-4, tying Rain Or Shine and NorthPort for joint seventh to ninth places.

A cold start by the Tropang Giga saw them score just 7 points in the first quarter, as Phoenix raced to a 17-7 lead, which the Fuel Masters extended to as many as 16 points in the second quarter.

After an anemic offense in the opening period, TNT dumped 31 and 33 points, respectively, in the second and third to narrow the deficit to 74-71.

After a Kib Montalbo 3-pointer put TNT up 88-85 with 4:25 left in the game, Phoenix had a chance to even the score but RJ Jazul could only sink one out of three free throws, after Montalbo fouled Jazul from behind the arc.

Kaleb Wesson's layup tied the game heading into the final 2 minutes, then Encho Serrano split his free throws after a foul by Jayson Castro, pushing Phoenix in front 89-88.

The Tropang Giga squandered their chance to grab the lead back after Calvin Oftana's turnover on a Tyler Tio steal and Roger Pogoy missed on a layup.

Tio then iced the game with two free throws after Castro was forced to foul.

Wesson finished with 23 points and 17 rebounds, Serrano added 16 points off the bench, and Javee Mocon chipped in 13 points and 5 steals for Phoenix, which overcame TNT's 14-of-35 shooting clip from 3-point territory.

Oftana scored 27 points, Pogoy had 22, and Cameron Oliver tallied 22 points and 10 rebounds for TNT.
