UST took the first two sets before La Salle found their rhythm in the third frame to eventually force a do-or-die fifth set.
In Set 5, however, it was the Tigresses who showed championship poise as they raced to a 11-4 lead behind the effort of Maru Banaticla, who bucked a lethargic start to the game and kept the La Salle defense guessing with her varied attacks.
Plays by Ara Galang, Kim Fajardo and Season 74 MVP Abby Maraño kept the door open for La Salle, but a cross court attack by Judy Caballejo put the Tigresses at match point, 14-7.
25-22, 25-13, 12-25, 21-25 and 15-9
