MANILA, Philippines — Faith Nisperos will take charge once more for National University (NU) when it begins its campaign for a fifth consecutive title in the UAAP Season 81 high school volleyball tournament at the Blue Eagle Gym. After drawing an opening day bye, the Bullpups will take on De La Salle-Zobel in the first of a three-game bill on Sunday at 1:30 p.m. The tournament officially opens on Saturday, with last season’s runner-up, University of Santo Tomas, battling UP Integrated School at 1:30 p.m. La Salle-Zobel takes on University of the East at 3 p.m., and Far Eastern University-Diliman and Adamson University wrap up the schedule at 4:30 p.m. Nisperos was the Finals MVP in Season 80, when the Bullpups swept the Junior Tigresses in the best-of-3 series. A two-time season MVP winner, Nisperos is now the team captain of NU after veteran Joyme Cagande moved up to the collegiate level. Meanwhile, UST opens its title-retention campaign in the boys division against NU at 12 noon. Other scheduled boys matches beginning at 7:30 a.m. are Ateneo-UPIS, FEU-UE and DLSZ-Adamson University.
