MANILA -- Adamson University took care of business against UP Integrated School, 21-8, 21-15, and secured the remaining girls' Final Four berth in the UAAP Season 87 high school beach volleyball tournament Friday at Sands SM By The Bay.

Ella Gonzalvo and Maegan Pineda made sure that the Junior Fighting Maroons pair of Janella Guarino and Anya Capus won't pull another reversal by controlling the do-or-die match early to power the Baby Falcons to finish fourth in the eliminations with a 2-3 record.

Adamson's entry ensured the same Final Four cast from last season.

National University Nazareth School completed a five-match elimination round sweep and clinched the No. 1 ranking in the Final Four after Vilmarie Toos and Faith Mangyao overwhelmed De La Salle-Zobel's Aislinn Alemaña and Kylie Celada, 21-5, 21-2, in the 24-minute early morning duel.

The Bullpups will play the Baby Falcons in Sunday's semifinal.

Defending champion University of Santo Tomas took the No. 2 ranking with a 4-1 record as Cheng Dadang and Angelica Del Mar subdued Far Eastern University-Diliman's Sheena Cafe and Sheila Pascual, 21-15, 21-10, in a Final Four preview.

The Baby Tamaraws finished third with a 3-2 slate, and hope to get back against the three-peat-seeking Tiger Sands in Sunday's Final Four.

UPIS, which earned its first-ever beach volleyball victory by beating De La Salle-Zobel last Sunday, wound up fifth with a 1-4 record. The Junior Lady Spikers, meanwhile, went without a win to show in five matches.

In the boys' division, league-leading UST and back-to-back title-seeking NUNS secured the two Final Four berths.

The Tiger Sands extended their perfect run to five matches after JM Lagaran and Lance Malinao defeated University of the East's Clarence Gianan and Buenaventura Limpin, 21-11, 21-13.

The Bullpups climbed to 5-1 in second place as Wayne Dionela and Kian Tan defeated Ateneo's Santiago Avila and Kevin Gabia, 21-5, 21-9, before returning in the afternoon with a dominant 21-1, 21-13 victory over UPIS' Terren Villanueva and Marcus Bamba in the 23-minute match.

The Bullpups scored the first 20 points of the match before finishing the first set in just nine points.

Adamson moved to within a distance of NUNS at 4-1 after Brice Malinao and Gian Ygot made short work of De La Salle-Zobel's Antonio Papa and Mario Roxas, 21-10, 21-16.

FEU-D rose to 3-2 after Zedrick Calimlim and Coronel overpowered UPIS' Villanueva and Bamba, 21-6, 21-7.

The Junior Green Spikers fell to 2-3, while the Junior Warriors and the Junior Fighting Maroons slipped to 1-4 and 1-5, respectively.

The Blue Eagles have lost five in a row.
