Local ace Samantha Ortega upended top seed Mary Brigoli in a grueling three-set quarterfinal battle then went to capture the girls' 18-and-under singles crown with a 6-0, 6-2 romp over Vinz Penalosa and complete a 'double' in the PPS-PEPP Mayor Aljun Diamante national juniors tennis tournament in Tuburan, Cebu over the weekend.

After besting Donna Mae Diamante, 6-4, 6-1, in the 16-U finals at the Roy Tabotabo clay courts, Ortega got past Gesellyn Constancio. 4-1, 4-1, in the first round in 18-U play then pulled off a 4-0, 2-4, 10-7 victory over Brigoli before ripping Jamie Carmona, 6-1, 6-2, in the semis. She then dominated Penalosa in a duel of unranked bets after the latter bundled out second seed Cheska Mamac, 6-4, 6-2, in their side of the semis duel.
