The Pointers took a 1-0 lead 2:18 into the game as Henegar scored on the power play after an elbowing call on Superior gave the Pointers the man advantage.
Superior evened the score at 1-1 midway through the second period, recording a power play goal at 12:06.
UWSP responded just two minutes later when, coming off a 'Jacket power play, Freismuth tallied an even strength goal, putting the Pointers back on top, 2-1.
In the third, Brandon Jaeger (Champlin, MN/Champlin Park) and the Pointers defense turned away each Superior scoring opportunity to hold on for the one-goal victory.
Jaeger stopped 13 saves on the night while his counterpart Drew Strandberg tallied 15.
