Northfield cut into Red Wing's 3-1 lead in the second period, but the Wingers responded with two third-period goals for a 5-2 win over the Raiders on Tuesday.
Mack and Jack Maroushek scored goals around Carson Van Zulien's in the first, with Cam Blue adding a third for Red Wing at the 16-minute, 33-second mark.
Northfield's Josh Kruger made it 3-2 with a goal at 9:22 of the second.
Blue (4:27) and Michael Stoffel (10:44) put the game out of reach in the third.
Zach Harding faced just 17 shots in the victory, stopping 15. Will Fink wasn't all that busy, either, saving 16 of Red Wing's 21 shots.
