The No. 1-ranked Gophers held a one-goal lead for about the last 23 minutes of their border battle with Wisconsin.
And then, with their goalie pulled, the No. 3 Badgers tied the score at 3-all on Britta Curl's goal with 10 seconds left. After a scoreless five-minute overtime, Saturday's game at LaBahn Arena in Madison, Wis., will officially count as a tie.
Minnesota, however did with the shootout — Abbey Murphy was the only shooter of six to score — for an extra point in the WCHA women's hockey standings.
Peyton Hemp scored the first two goals for the Gophers (9-1-2, 9-0-2) and Grace Zumwinkle the third.
Zumwinkle's eighth goal of the season at 16 minutes, 44 seconds of the second period broke a 2-all tie. Minnesota now has a five-game unbeaten streak (3-0-2) against the Badgers going back to last season.
Zumwinkle, a fifth-year senior forward from Breck, has at least one point in 11 of Minnesota's 12 games this season. She has a team-high 18 points.
Wisconsin (10-2-1, 7-1-1) took leads of 1-0 in the first period and 2-1 in the second on goals by Vivian Jungels and Laila Edwards.
Hemp answered each time, scoring shorthanded at 15:55 of the first and at 6:53 of the second. The sophomore forward who played at Andover, has six goals this season.
