Sophomore attack Amanda Roper had a season-high five goals, including the go-ahead score in the second half as the Lions beat Lake Sammamish 13-7.

MERCER ISLAND — Lakeside scored eight second-half goals to win its ninth state girls lacrosse championship with a 13-7 defeat of Lake Sammamish Friday night before nearly 1,000 at Islander Stadium.

Sophomore attack Amanda Roper had a season-high five goals for the Lions (15-1), including the go-ahead score in the second half.

It was the first trip back to the podium for coach Jamie Asaka’s Lions since winning five straight titles from 2006 to 2011. Lake Sammamish (14-3), made up of students from eight Eastside high schools, was denied a title for the second time in two years.

After falling behind 6-5 at the half, the Lions took advantage of a yellow card issued to Lake Sammamish attack Claire Monsaas with just 30 seconds to go in the first.

With Lake Sammamish’s top scorer out early in the second, the Lions converted the player-advantage into back-to-back scores by Roper and senior Kaylee Best.

“(The win) felt great. I’m so proud of this team,” said Asaka, who made several matchup adjustments at the half that helped turn the game’s momentum.

“We said before the game that if we’re even or close to even on draw controls we’ll be successful,” said Asaka. Her Lions controlled 15 draws to just eight by Lake Sammamish.

“We switched up the matchups. Once we were able to do that, we were able to get into more of a rhythm,” she said.

Roper also had an assist for six points, while goaltender Amerra Scheckles came up with seven saves to earn co-MVP honors.

“We moved the ball really well,” said Roper, who tallied four of her five scores in the second half. “The lanes just opened up, so I really was the only one available. But honestly, I feel that everyone on our attack could have done that.”

After Lakeside took its second lead of the night on a Best score just 1:13 into the second, Emily Sokol connected for Lake Sammamish’s seventh to knot the game for the fifth time at 7-7.

That was all the scoring for Lake Sammamish, as Roper struck again at 13:52 to make it 8-7 and give the Lions the lead for good.

While Roper’s goal launched a six-goal run, it was Sheckles’ performance in goal that shut down a Lake Sammamish team averaging more than 11 goals per game during the regular season.

“I was just trying to save as many as I could for my team,” said Sheckles, who had four critical stops in the second half. “The saves were just a matter of my team having my back.”

Along with Roper’s six points, Best, Natalie Fox and Rebecca Long each had two goals to lead the Lions.

For Lake Sammamish, Alexandra Johnson led the way with four goals and one caused turnover.
