BILLERICA — There easily could have been plenty of panic in the Burlington locker room during the second intermission of Thursday’s Division 2 boys hockey quarterfinal at the Chelmsford Forum after Concord-Carlisle tied the game at one in the final minute.

Instead of panic, it was sticking to its game plan that paid off in the third as the Red Devils scored three unanswered goals to defeat the Patriots, 4-1, to earn their Final Four spot.

“We played really well in the third,” Burlington coach Bob Conceison said. “We knew that this was gonna be a battle. We played against a good team, and a good goalie and just kind of stuck with it.”

It didn’t take long for Burlington to break the tie in the third.

Sam Griswold, who made 25 stops in his swan song, lost his stick in the crease, and before he could retrieve it, Jake Griffin made a perfect feed to a wide-open Avery Shanahan for a one-time between the pads at 2:01.

Less than a minute and a half later, the Patriots were caught with too many men on the ice, handing Burlington its first power play of the game.

Less than 20 seconds later, junior Nick Tulipano had his second goal of the night off a perfect cross-ice pass from James Gordon when his shot went between Griswold’s arm and the post.

“That goal was huge. Continuing to capitalize on that momentum was really big,” Conceison said.

Concord-Carlisle called timeout to try and calm the momentum but on the very next shift, the Red Devils delivered the knockout punch.

A scramble in front of the Patriots’ net eventually ended with Ryan McWhinnie tapping home a loose biscuit for Burlington’s third goal on only six shots in the first 4:28 of the third.

From there on, it was clean sailing for Burlington as Colin MacLeod only had to make five saves in the third period.

“Concord played really hard. And we just found a way in the third period to persevere and put a couple in,” Conceison said.

Neither team scored in the first before Tulipano opened the scoring five minutes into the second, scoring on a wraparound off a scramble in front of Griswold.

C-C had a pair of power plays go by the board before a whiffed Alex Fivek shot with :56 left turned into a wide open net for Chris Bono to tie the game.
