Freshman netminder James Offner stopped a career-high 30 shots on Monday night to pick up his fourth career win, as the Sachems (8-7-4) knocked off No. 4 Hingham, 1-0, in Winchester.
The win is the second in row over a ranked opponent for Offner and the Sachems, who defeated No. 13 Woburn, 3-2, on Saturday.
"James is on the small side," said Winchester coach Matt Stang. "He likes to come out and cut down on the angles and is a quick kid. He plays with a lot of poise for freshman and has been on a role as of late."
Senior winger Michael Marx netted the game-winner on the power-play midway through the first period, when he cleaned up the rebound on a shot from the point by Alex Sharp.
Midway through the third period Offner showed his poise, making his best save of the night, sliding to stop a Harbormen (13-4-1) two-on-one attempt.
"That was pretty much Hingham's only quality scoring chance in the third," said Stang. "We did a nice job limiting their scoring chances and clearing the puck out from in front of our net.
"It's nice to finally have some momentum," continued Stang. "We had a couple of tough losses early on and couldn't get over the hump, but in the last few weeks we've kind of figured things out."
The goal was the sixth of the season for Marx, whose team won despite being outshot, 30-16. Offner now has 57 saves in his last two games.
The Sachems must win one of their three remaining games to earn a spot in the state tournament.
