Freshman goaltender Christine Dufour gave up her only goal in the first period, as Bemidji State freshman forward Kelly Hart got an unassisted goal at just more than three minutes into the contest, giving the Beavers a 1-0 lead they protected for most of the game.
Senior forward Meghan Hunter kept the Badgers in the game with a goal five minutes into the third period. Less than two minutes later, freshman forward Meaghan Mikkelson scored the game-winning goal for Wisconsin.
Dufour had 15 saves while Bemidji State senior goalie Anik Cote had 34 saves.
The Badgers finish the regular season 24-5-3 overall and 18-5-1 in the Western Collegiate Hockey Association, setting a record for the program's best finishes in both conference play and overall. Wisconsin finished runner up to Minnesota in the WCHA standings.
"I'm happy for our seniors," head coach Mark Johnson said. "They had great careers. Some of their roles changed over four years, but they won a lot of hockey games. They won 20-plus games a year for four years and that's been a tough task for a lot of players that are here for four years to accomplish."
The team is not finished, however, and these seniors have more tasks to accomplish before they exit the ice. The second seeded Badgers travel to Minneapolis for the WCHA Final Five next weekend, where they will face off against No. 3 seed Minnesota-Duluth in a conference semifinal Saturday.
"To finish the regular season the way that we did, it was a great year for these kids," Johnson said. "They won more games than any other team in the school's history, so they have a lot to be proud of and now it's going to come down to a one-game showdown in Minneapolis next Saturday against Minnesota-Duluth."
Wisconsin may need to win the WCHA tournament in order to secure one of only four slots in the NCAA tournament. The Badgers are currently ranked fifth in the PairWise rankings.
