The Tommies (13-0-1 overall, 7-0-1 MIAC) took three of the four points on the weekend. They pushed their unbeaten streak to 27 games (21-0-6) dating back to last season.
The Purple remain alone in first place by two points over 6-1-1 Hamline, with 5-1-2 Concordia and 5-2-1 Gustavus also closely in the chase.
The Gusties scored just 28 seconds into the game and went ahead 2-0 with under 7:00 elapsed. But the Toms shut down GAC over the next 58:00 on the clock and killed off all five power-play tries.
The Tommies play Bethel next weekend.
