WAHIAWA — Kaiser won its first O'ahu Interscholastic Association boys wrestling championship since 1984 last night, edging four-time defending champ Kahuku, 163.5 points to 157, before a crowd of about 1,100 at Leilehua Gym.

The Cougars were led by individual champions Jason Spiker, a sophomore who won the 103-pound title, and senior C.J. Criado, who captured the crown at 171 pounds.

Kaiser also had two runners-up (Kevin Tomita at 135 and Shane Yakabe, 140), one third-place finish (Byron Apo, 125), one fourth (Blake Ling, 130), one fifth (Roland Fernandez, 112), one sixth (Stanley Good, 189), one seventh (Brian Freeman, 152) and two eighths (Sean Harkin at 215 and Tuapasi Teotu'u, 285).

The Cougars dominated the OIA in the late 1970s and early '80s, winning five straight league championships from 1978 to 1982 and another in 1984. But they had been shut out since, until last night.

"It feels awesome," said Criado, who wrestled as a freshman but sat out his sophomore season with a pinched nerve and skipped last year to concentrate on football. "We had a good group this year, a lot of tough wrestlers. I knew we had a good JV team last year, and they all stepped up this season and a lot of them placed."

Criado defeated Pearl City's Christian Pavo, 5-1, in an intense final last night after they split their previous two meetings this year. Spiker, whose brother Jonathan was Hawai'i's second four-time state champion at Saint Louis (2000 through 2003), pinned Kalani's Michael Nakagawa in the semifinals and Kahuku's Roger Ramones in the title match.

"Jason had a huge day, taking out the top two guys with pins," Kaiser coach Mike Kim said. "He had a slow start the first half of the year, but he's really come into his own. With it being so close, every point that every kid scored for us was crucial."

The girls team competition also was closely contested, with Kahuku edging defending champion Farrington, 164.5 points to 158.5, for its fourth title in the past five years.

The Red Raiders had three individual champions — Danica Auna (125 pounds), Amanda Keli'iho'omalu (130) and Amanda Soliai (155) — and one runner-up (Cianah Hee, 120). Kahuku also had two third-place finishes (Kalae Johnson at 108 and Chelsy Eugenio, 114), one fourth (Phoebe Arnett, 103) and two fifths (Andrina Ramos at 98 and Erin Ah Sue, 140).

"(Auna and Soliai) beat people who they lost to last week, so those were eight big points right there," Kahuku coach Reggie Torres said.

'Aiea senior Ren Yamashita won at 103 pounds and sister Joy, a freshman, won at 114. They are believed to be the first sisters to win OIA titles in the same year.
