Sophomore attackman Matt Shields registered a game-high six points on five goals and one assist to lead No. 9 Mercer Island to a 19-4 victory over Curtis in a Washington High School Boys Lacrosse Association Division I semifinal Wednesday night.

Senior middie Steven Caditz added five points on four goals and one assist to help the Islanders (18-4) easily advance to the Division I state championship game.

Mercer Island, which has won 12 straight, will next face No. 15 Issaquah on Saturday night, May 30, at Memorial Stadium at 7:30 p.m., PDT. In the teams’ only regular-season meeting, the Islanders beat the Eagles, 6-4, on April 24.

The Islanders will be going for their fifth state title and first since 2006.

“We’re excited,” Mercer Island head coach Ian O’Hearn said. “We’re just going to come out and keep playing the way we’ve been playing. It’s going to come down to who gets the most possession.”

On Wednesday, the Islanders won despite playing without U.S. Lacrosse All-American selection Daniel Shields, who broke his ankle in practice Monday and is out for the season. However, his absence hardly mattered.

Junior middie Jonathan Wettack finished with five points on three goals and two assists, freshman attackman Connor Bernal had four points on three goals and one assist and junior attackman Michael Black added four points on a goal and three assists for Mercer Island.

Other offensive contributors included junior middie Steven Taylor, who had three points on two goals and one assist, sophomore middie Doug Mahony, who dished a pair of assists, and sophomore middie Peter Iani, who scored once.

Defensively, junior goalie Hap Giraud saved six shots.

In defeat, Landon Carr and Taylor Dean each scored twice for Curtis, which finished the season 12-5.

Mercer Island led 6-0 at the end of the first quarter, 13-3 at halftime and 18-4 at the end of the third quarter.

“Everybody stepped up,” O’Hearn said. “I think, if anything, losing Daniel really motivated everybody.”
