The boys’ hockey team ended its four-game losing streak with a solid 4-1 win over Greater Boston League entry Medford High School, on Saturday afternoon at The Bog. After an ugly blowout loss to Archbishop Williams last Monday night, the Dragons (5-5-1) got back in the win column behind the goaltending of sophomore Derek Williams and the play of senior captain Pat Charland, who scored two goals and added a pair of assists in beating the Mustangs (5-4). It was Williams’ first varsity victory in his debut.

The Dragons thought they had grabbed an early 1-0 lead just over a minute into the game when a power-play goal was disallowed with the net coming off its post. The bad news didn’t seem to stop Duxbury’s offense, as sophomore Connor Doyle had a pair of scoring bids stopped by Medford’s Mike Gendreau over the next couple of minutes.

Williams had his first big save of the game with 8:23 to go, as he flicked his stick at a redirected shot to keep the game scoreless.

The Dragons had their second power play with 4:05 left in the period, but Medford captain Nick Squillaciotti did an outstanding job of pinning the puck in the corner for close to 30 seconds and killing Duxbury’s momentum.

Both teams played shorthanded to start the middle period. However, with the Mustangs on the power play, the hard work of Charland paid off. The senior forward stole the puck on the forecheck and beat Gendreau for a 1-0 lead.

Williams made a spectacular save right off the faceoff to keep the lead intact. However, the Mustangs kept coming and scored at the 5:26 mark when Guy Leone finished off a two-on-one break to knot the game.

Duxbury went on the power play in the first two minutes of the final period, but they gave the advantage back 22 seconds later with both teams playing even for 1:08.

Sophomore Will Siefert finally got his team the lead for good when he found himself in the left faceoff circle where he blistered a shot past Gendreau’s stick side for a 2-1 lead with Charland and Doyle registering assists.

The undisciplined Mustangs put themselves in a hole less than a minute later, when the Dragons went on the power play and broke the game open with Charland connecting for his second goal with assists to sophomore defenseman Mitch Barrington and junior captain Bryan Barry.

Williams was at his best in the final seven minutes, stopping a point blank shot from the slot with 6:22 to go, and holding the Mustangs off the scoreboard while killing two power-plays back to back with less than four minutes left in the game.

Medford would rattle two shots off the post after pulling their goalie in the final 1:30, allowing Barry to finish the scoring for the Dragons with 59 seconds remaining.

“We felt comfortable out there and just wore them down,” said Blake. “We needed this game and I told the kids we needed to stay disciplined because Medford had a reputation as an undisciplined team.”

Duxbury now gets it toughest test of the season this Saturday when it hosts its annual battle with Hingham at 4 p.m. at The Bog.
