Three Tigresses finished in double digits as Judy Caballejo finished with 13 points while guest players Mary Jane Balse and Utaiwan Kaensing chipped in 14 and 12 points, in that order.
A service error from the Lady Stags sealed the victory for the Tigresses in a tight-decision set, which was a stark contrast from the first two.
The Tigresses had a huge advantage all throughout, but allowed the Lady Stags to come within three points, 21-24, in the final frame.
UST handed San Sebastian, which only had veteran Thai import Jeng Bualee grinding out double time, its first loss of the tournament.
Bualee, who’s been with San Sebastian for several years now, finished with 14 points while the rest of the squad combined for 13 points.
