Alex Iafallo gave the University of Minnesota Duluth its only lead of the afternoon, but it was the one that counted the most.

The senior left winger scored with 15.6 seconds remaining in the third period to break and 3-3 deadlock and lift the No. 6 Buldogs past No. 17 Michigan Tech University in a rare Sunday matinee at AMSOIL Arena. The 4-3 victory, which followed up a 6-0 triumph Saturday night, gave UMD its first season-opening series sweep since the 1995-96 season.

Michigan Tech twice held two-goal leads, the first coming in the opening period when Reid Sturos and Tyler Heinonen scored five minutes apart in the first 8:21 of the game. Senior left winger Kyle Osterberg cut the Bulldog deficit in half with a redirect off of senior defenseman Dan Molenaar's shot with 29 seconds to go before the intermission. That goal, which was Osterberg's second of the weekend, was answered by the Huskies at 9:29 of the second period but a little under eight minutes later, sophomore Neal Pionk brought the Bulldogs to within one by blasting a shot from the left point past Michigan Tech goaltender Devin Kero while UMD was on a 5-on-3 power play. Sophomore right winger Billy Excell then stuffed in a puck off a scrum in front of the Michigan Tech goalmouth for his first collegiate goal midway through the third period before Iafallo capped off the comeback, converting a nifty feed from Pionk, who led all Bulldogs with two points.

"We got off to a slow start and we were probably thinking about last night rather than the game today," said Iafallo, who leads all active Bulldogs in career scoring with 72 points. "We just kind of came together in the third period and we were able to put one in."

Rookie Hunter Miska, who one day earlier became just the second Bulldog to post a shutout in his collegiate debut, finished with 18 saves and played a key part in holding Michigan Tech scoreless on all six of its power play opportunities Sunday -- and all 10 chances over the weekend. The Bulldogs were 1-for-7 with the man advantage and 4-for-13 during the two-game series. UMD received points from 11 different players, including sophomore right winger Adam Johnson, who had a team-leading seven of UMD's 31 shots.

"It was a good team character win, for sure," said Osterberg. "Good teams find a way to win and we just stuck with our game and it was a big goal at the end for Al (Iafallo)."

The Bulldogs will take its show on the road next Friday and Saturday for a two-game set against No. 8 University of Massachusetts-Lowell.
