LEWISTON — There is a reason why the Lewiston High girls’ hockey team is undefeated. The Blue Devils played a complete game in beating Yarmouth/Freeport/Gray-New Gloucester 4-0 Monday night in the Eastern semifinals at the Colisee.

Top-seeded Lewiston outshot the No. 4 Clippers 47-21 and all-state goalie Paige Fontaine made 21 saves. Corinne Laberge scored two goals. Lauren DeBlois had a goal and two assists.

“They’re a machine,” Yarmouth Coach Jeff Haley said. “And that’s an absolute confidence. The way they run their system …. They are who they are.”

The Blue Devils (18-0-1) move on to play No. 2 Edward Little/Leavitt (15-2-1) Wednesday in the East final at the Colisee.

The West final between Falmouth and Scarborough will also be Wednesday at the Colisee. Times will be announced later.

The state championship is Saturday night at the Colisee.

Lewiston has handed Edward Little its two losses this year. The Blue Devils also had beaten Yarmouth (11-8-1) twice during the regular season, but in their last meeting on Jan. 24, the Clippers played Lewiston close in a 5-3 loss.

On Monday, Lewiston had a 2-0 lead going into the third period. The Blue Devils scored twice in the first 3½ minutes of the period to seal it.

“Good job,” Lewiston Coach Ron Dumont said. “I’m real proud of what we did.”

Despite the overwhelming edge in shots, the Clippers did have their chances. Emily Johnson, Katie Clemmer, Jenny Holmquist and Michelle Robichaud all had quality shots, but Fontaine was there.

“They were getting that quick break on the far wing, and they got some shots off of that,” Dumont said. “But (Fontaine) has just been solid as a rock.

“What you like with any goalie – and she has proven it before – once it’s time for the playoffs, she gets really focused.”

The Blue Devils recorded their 12th shutout of the season Monday.

“We couldn’t get people in front of the net for tips, screens and rebounds,” Haley said.

On the other end of the ice, Yarmouth goalie Hannah Williams made 43 saves.

Lewiston took a 1-0 lead in the first period with a power-play goal. The Clippers had killed a five-on-three advantage. Lewiston kept feeding DeBlois, who features a cannon shot.

With the five-on-four advantage, DeBlois finally broke through at 8:57.

Laberge scored in the second period, skating around a defender and wristing in a shot at 4:57.

In the third, defenseman Mikaela Brown scored 46 seconds into the period on a wrister. Then Laberge scored on a rebound at 3:30.

On Wednesday, Lewiston will be trying to reach the state title game for the second straight season and the fourth time overall. The Blue Devils lost to Scarborough in last year’s championship game.

This was the Clippers’ second straight trip to the East semifinals.

After the game, Haley had to say goodbye to four seniors: Robichaud, Williams, Johnson and Katie Brown.

“These girls have really moved this program in the right direction,” Haley said.
