Josh Albelda, ABS-CBN Sports UP will next face defending champion Adamson in the Final Four.

MANILA, Philippines – The University of the Philippines (UP) routed De La Salle University, 10-3, to claim the last spot in the Final 4 of the UAAP Season 79 softball tournament on Thursday at the Rizal Memorial Baseball Stadium.

The Lady Maroons had two outs in the second frame, but still managed to unload eight runs, as the Lady Archers succumbed to a series of errors in what turned out to be the turning point of the game.

UP thus set up a semifinals meeting against defending six-time champion Adamson University on Saturday, also at the Rizal Memorial Baseball Stadium.

The other Final 4 pairing pits second seed National University (NU) against last season's losing finalist, University of Santo Tomas (UST).

The Lady Falcons and the Lady Bulldogs hold a win-once bonus over their respective opponents.

A semifinals decider, if necessary, will be played on Monday.

Last Wednesday, La Salle kept its bid for back-to-back baseball titles alive with an 8-5 win over early finalist Ateneo de Manila University.

UST and Adamson were tied at six after 11 innings, when their game was suspended due to darkness. The game will resume at a later date yet to be announced.

The Growling Tigers, who have a 6-2 win-loss record in second place, need to beat the Falcons in order to advance to the title round against Ateneo.

The Green Archers improved to 5-4 in the third spot. La Salle can force a playoff for the last championship berth if it beats UP on Sunday, and UP loses to Ateneo and Adamson in the resumption of their abandoned game.

NU defeated UP, 12-7, in a no-bearing game.
