Earlier, UST placed one foot inside the Final Four door after rallying back from a set down to repulse University of the Philippines (UP), 23-25, 25-21, 25-22, 25-19.
Angge Poyos spearheaded the Golden Tigresses’ charge to secure at least a playoff for a semifinals seat as they improved to an 8-5 win-loss record in solo fourth spot.
UST’s victory also created a separation to fifth-running Far Eastern University (FEU) (7-6) in the race for the remaining ticket to the next round.
La Salle, three-peat-seeking NU and Adamson University occupy the first three semis berths.
Poyos scored 24 of her 25 points on attacks and added 11 digs and eight excellent receptions for an all-around performance for UST, which can claim a semis seat and avoid complications with a win over NU on Wednesday at the Smart Araneta Coliseum.
“Well, we know how super important this game was for our campaign for the Final Four. It’s a virtual band-aid for the meantime for our ranking and standing,” Tigresses assistant coach Yani Fernandez said.
In the event of a two-way tie at 8-6 between UST and the Lady Tamaraws, a playoff takes place if FEU beats also-ran Ateneo de Manila University on Wednesday.
The two squads will play a sudden-death match next Saturday to decide which team will advance to the next stage.
“This game is very crucial and our mindset as a team is to give our best, leave nothing behind and just give our 100 percent. Give everything so there will be no regrets. Trust in our teammates and the system that we have,” said Poyos, who added 11 excellent digs, and eight excellent receptions.
Regina Jurado contributed 17 points and eight rebounds while Jonna Perdido had 13 points and nine excellent receives for UST.
The Tigresses were able to regroup after a sluggish start and denied the Fighting Maroons a chance to score in their final game of the season.
UP ended its campaign with a 5-9 slate.
Graduating middle blocker Nina Ytang finished with 19 points while outgoing Irah Jaboneta had a triple-double in her farewell game with 16 points, 17 excellent receptions and 11 digs for the Fighting Maroons.
Jelai Gajero and Kianne Olango had 12 and 10 points, respectively, for UP.
In men’s play, UST put itself in a good position to vie for a Final Four twice-to-beat advantage after sweeping UP, 25-14, 25-17, 25-16, for a third straight win and a 9-4 record.
The Golden Spikers can snatch a semis incentive and the No. 2 seeding with another victory over six-peat-seeking NU on Wednesday.
Fate favored UST in the chase for the last Final Four bonus after also-ran De La Salle University scored an end of elimination round upset over the Bulldogs in a gutsy 16-25, 26-24, 20-25, 26-24, 17-15, escape.
The Green Spikers’ win that snapped a three-game slide for a 6-8 finish, pulled NU down to a 10-3 slate and formally handed league-leading semis twice-to-beat FEU (12-1) the top-seeding in the next round against Ateneo.
A win by the Golden Spikers over the Bulldogs will force a playoff for a twice-to-beat advantage. If NU wins, it will occupy the No. 2 seed outright with a Final Four incentive against the same rival.
