The Crimson fell behind early when Guest beat Boe to a rebound and buried the puck into the back of the net, giving the Bulldogs a 1-0 lead with just over four minutes elapsed in the first period.
Harvard struck back quickly, scoring its first of two power-play goals on the evening. At 15:12 of the first period, sophomore forward Jennifer Raimondi found some room to the left of the goal and fired a slap-shot by Schaublin.
Despite a flurry of offense from the Bulldogs, Boe and the Crimson defense managed to keep the game tied at one until Potter’s goal late in the second period.
“Duluth played a very good game offensively,” Boe said. “But the [Harvard] defense did a good job not allowing second-chance opportunities.”
Harvard returns to action next year for a two-game homestand against Vermont and rival No. 2 Dartmouth Jan. 10-11.
