Gabriel Tiamson put one over top seed Miko Eala, hacking out a 6-4, 6-2 decision to capture the boys’ 12-and-under title in the 2012 Age-Group Tennis Championships at the Rizal Memorial Tennis Center.

The second seeded Tiamson, playing out of De La Salle-Zobel, broke the fancied Eala once in the opening set then used a variety of shots to dominate the second en route to the straight-set victory.

Eala, however, salvaged the 10-unisex crown, blanking Juan Miguel Jugo, 6-0, 6-0.

Jan Godfrey Seno took the boys’ 14-under diadem with 6-2, 6-0 win over Justine Prulla, while Betto Orendain repulsed Stefan Suarez, 6-4, 3-6, 6-4, to cop the 16-under plum.

John Maverick Victoria, however, foiled Orendain’s bid for a second title as he fashioned out a 7-6 (2), 6-4 win in the 18-under finals to share the honors with Roxanne Resma, who took the girls’ premier crown with a 6-0, 6-1 rout of Ma. Dominique Ong.
