Kahuku’s domination of Oahu Interscholastic League girls water polo continues.

Led by senior Brooke Roy, who scored seven goals, and the tenacious defense of her twin sister, Tahnei Roy, and senior goalie Penn Anderson, the Red Raiders defeated Mililani 14-7 yesterday at the Kaimuki High School pool to win their second consecutive OIA championship and seventh since girls water polo began as a sanctioned sport eight years ago.

Roosevelt took third place with a 14-10 win over Leilehua, and Kaiser finished fifth after beating Kapolei 7-2. Every team that played yesterday had already qualified for the state tournament, which will be held May 4-7 at Kamehameha-Hawaii on the Big Island.

Throughout the regular season and the OIA championship tournament, Kahuku’s potent offense, stifling pressure defense, precision passing and signature depth of talent were on display as the team compiled a perfect 14-0 record.

During the regular season, the Raiders led the OIA in team offense and defense, scoring an average of 15.5 goals a game and limiting opponents to 1.8. In the championship tournament, it also was the leader in both categories, scoring an average of 17.7 goals, while allowing an average of 5.0.

And of its 17 position players, 13 scored during the tournament.

Coach Makana Leiataua said if her squad was broken down into A and B units, they would probably be two of the top three teams in the OIA.

But for Leiataua and her team, their league achievements are a steppingstone to a more challenging goal: returning Kahuku to the state championship match for the first time since 2007, and winning its first state championship. Punahou has won five of the past seven.

"We’re not done. We got two more weeks to go," said Leiataua, who in her first three years at Kahuku’s helm has guided the Red Raiders to two third-place finishes and one fourth at states. Her team needs to stay focused and motivated, and remain healthy, she added. "We haven’t reached our potential yet."

Leiataua had her team scrimmage Punahou three times this season.

Anderson and Brooke Roy said those scrimmages have helped the Raiders. "You play better, you improve, when you play against the best," Anderson said.

Brooke Roy, who led all OIA tournament scorers with 14 goals and who finished fifth in the regular season with 39, added: "They’re a good team, but we’re not afraid of them. We feel we can give them a run for their money."

Both Roys and Anderson will be playing water polo collegiately at Golden West College in Huntington Beach, Calif. The school is known for having one of the best water polo programs among small colleges.

Punahou led the Interscholastic League of Honolulu with a 6-0 record. It is widely favored to win the ILH title during this week’s championship tournament, and return to the state meet in a quest for its fourth consecutive state crown.
