LEWISTON – If Monday is any indication of things to come, Lewiston sure picked the right time to find its old form again.

The Blue Devils marched methodically up and down the ice all night, systematically shutting down the Messalonskee offense while producing plenty of their own in a 5-0 quarterfinal win over the Eagles at the Androscoggin Bank Colisee.

“We know we can’t let up anymore,” Lewiston forward Jon Roy said. “We were letting up second, third period, and we know that no one can really skate with us if we put three solid periods together, and we just want to keep that going.”

Lewiston shot out of the gate this season, averaging nearly 10 goals per game. As the opponents got tougher, though, the offense sputtered a bit. Two weeks ago, Gagne changed his lines up, essentially creating two No. 1 lines.

His moves have paid off.

“You can’t key on three guys anymore,” Lewiston coach Norm Gagne said. “When you’ve got (Casey) Poussard on your second line, that’s dangerous.”

Roy, now playing alongside Jordan Bourgoin and Robbie Leeman, had a pair of goals to lead the Blue Devils on Monday. Bourgoin had a pair of assists on Roy’s goals, and Poussard, Sam Cloutier and Justin Nadeau had a goal each.

“We put in a new forecheck,” Gagne said. “We worked it against Brewer, and the kids are buying into it, and it’s working well. We’re spreading our opponent out because of it, and it’s creating chances.”

Freshman Cam Poussard turned aside 21 shots to earn a shutout in his first playoff game.

“Thank God Cam came up big in the first five minutes of this game, and to start the third,” Gagne said. “

Messalonskee held Lewiston to four goals the last time these two teams met, back in December on neutral ice at Ingersoll Arena in Auburn.

“Zach (Parent, Messalonskee’s netminder), I really believe, is one of the top three goalies in the state,” Messalonskee coach Mike Latendresse said. “He didn’t start all 20 games for nothing. He gives us a chance to win every time out.”

The Eagles’ lack of depth up front was apparent Monday. Beyond their top line, they struggled to keep pace with the Devils’ cycle down low, and their transition through center zone.

“They’re just a better, deeper team than we are, honestly,” Latendresse said. “Offensively, we just didn’t create enough. We had some opportunities, but it wasn’t consistent, and you’re not going to score a lot of goals that way.”

The teams played a quick-paced first period, trading shots for the first nine minutes. Roy put Lewiston on top at 9:40 when he finished a 2-on-1 with Bourgoin. Nadeau followed at 12:33 on a rush up the left side. His wrist shot hit Messalonskee goalie Zack Parent (32 saves) in the shoulder and fell into the cage.

Roy made it 3-0 at 6:36 of a Blue Devil-dominated second period on the power play, and Casey Poussard added another at 8:05 to widen the margin.

Cloutier batted his goal past Parent on a Poussard shot at 5:34 of the third to end the scoring.

Lewiston will play in the Eastern Class A semifinals Saturday at the Colisee against the winner of the Lawrence-Poland/Gray-New Gloucester game, scheduled for tonight at Sukee Arena in Winslow.
