Leading by two goals with a little more than three minutes to play, the Mavericks coughed up their lead, allowing two goals in a span of 40 seconds.
Minnesota State had some great chances to win the game in overtime with chances by Max Gaede, Zach Palmquist and Johnny McInnis, but they ended up with just one point and extended their winless streak to three games (four games in WCHA play).
Jean-Paul LaFontaine scored two goals for the Mavericks, and Teddy Blueger had the other.
Blueger got the scoring started just 55 seconds into the first period, getting an assist from Eriah Hayes. LaFontaine made it 2-0 with an unassisted goal with 2:41 remaining in the opening period.
Anchorage cut MSU's lead in half at 3:48 of the second period on a goal by Hayden Trupp, but LaFontaine built the advantage back up midway through the frame on during a power play.
The puck went off LaFontaine's skate, and the goal was reviewed, but LaFontaine did not kick the puck into the net. Before this season rules were clarified to allow goals off skates provided there is no distinct kicking motion by the player who scores. Zach Lehrke and Palmquist assisted on the goal.
Anchorage's comeback, which ended an eight-game losing streak, included goals by Blake Tatchell (power play) and Bobby Murphy.
Anchorage outshot MSU 24-22.
