Three years ago, a bleached-blond Shimatsu wearing No. 21 scored to lead the Mililani boys soccer team to the O'ahu Interscholastic Association title.

It happened again yesterday as Dustin Shimatsu scored a first-half goal to lead the Trojans to their fifth straight OIA title in a 1-0 win over Kapolei at Kaiser High.

"Me and my brother are always competitive," Dustin Shimatsu said of his older brother, Whitney, who was The Advertiser State Player of the Year in 2003 after scoring clutch goals for the Trojans. "I just try to keep up and strive to be better than him."

Mililani (10-1-1), Kapolei (11-1-0), Moanalua (10-2-1), Leilehua (8-4-1) and Kaiser (10-2-2) earned the league's berths for the state tournament that begins next week. As the OIA champion, Mililani will likely receive a first-round bye.

Like the girls game played just before, the teams dealt with windy conditions.

"We knew the wind was going to be a factor," Mililani co-head coach Jeff Yamamoto said. "We wanted to make sure we pressed."

Shimatsu, a senior forward, used the strong gusts to his advantage. He scored in the 12th minute after he dribbled to the left corner, held two defenders off before beating one, took a touch and sent a ball curling to the far right post.

"I just tried to cross and I was hoping somebody would get it," Shimatsu said. "The wind carried it and I put too much spin on it, and it went in."

Both Kapolei coach Bryce Kaneshiro and Yamamoto credited Trojans goalkeeper Michael Smith with keeping the Trojans in the game.

"He just came over and made the stops," Kaneshiro said.

Kapolei's best chance of the first half was on a free kick by junior midfielder Curtis Kiyabu, whose low driven shot skirted around the wall and was saved by Smith.

"We were still in high spirits at halftime because we knew we would have the wind at our back," Kaneshiro said.

Kapolei had a chance to tie in the 55th minute on a shot by junior midfielder Kainoa Bryant, who tracked a long clear after the Trojans defense pulled up to try to catch the Hurricanes offside. But Bryant's one-on-one shot was blocked by Smith.

Another Hurricanes' chance was thwarted when junior midfielder Kelsey Kikugawa cleared a ball off the goal line in the 70th minute.
