Last week, Roseau scored four third-period goals to erase a 4-1 deficit in a comeback win over rival Warroad.
On Tuesday night, East Grand Forks was aware of the Rams' recent late heroics.
"After the second, we talked about it," Green Wave coach Tyler Palmiscno said. "The third period has been their best this year. They were big in the third period against Moorhead and Warroad, which are two teams we haven't beat."
This time, there would be no comeback magic for the Rams.
East Grand Forks snapped Roseau's eight-game winning streak with a 3-1 win at the Civic Center.
"Other teams have been outplaying us in first periods, then we've figured it out after that," Roseau coach Andy Lundbohm said. "But we never got that next gear. Credit East Grand for keeping us on our heels all night long."
The Green Wave started hot, outshooting Roseau 21-5 in the first period.
A terrific stretch pass by EGF defender Logan Spencer sent Nathaniel Emery on a breakaway. Emery scored his second goal of the season at 13:45 of the first period for a 1-0 lead.
The only downside to the opening period for the Wave (11-3-2) was that they didn't build any larger cushion with the dominant effort against the Rams (12-4-0).
"We got outplayed in pretty much every area of the ice except our goaltender did extremely well," Lundbohm said. "In the first period, they were winning every battle and making every play."
Roseau goalie Andrew Tuttle made 33 stops, while East Grand Forks' Austin Cooley had 18.
Despite the lopsided shots on goal in the first, Roseau weathered the storm and tied the score at 1 at 5:18 of the second. Brendan Lund scored on a similar play to EGF's first goal, as he received a long pass to come in on a clean breakaway.
The Wave reclaimed the lead at 15:25 of the second by striking on the power play. Setting up on the right side of the power play, Landon Parker fed Jaksen Panzer in the slot. Panzer immediately tapped the pass back to Parker, who blasted a one-timer for the go-ahead goal.
East Grand Forks gained breathing room early in the third period. Spencer, who had a goal and two assists, scored from the blue line when his seemingly harmless chance navigated through traffic for the insurance goal in the first 30 seconds of the period.
"I liked the energy and intensity," Palmiscno said. "In the second and third periods, the game kind of evened out a bit but we were really tough defensively. They never had extended zone time because we were dialed in defensively. We played a really smart third period. We didn't force it and chipped pucks when we needed to."
