Michael Mersch's second goal was the game-winner Saturday as Wisconsin beat St. Cloud State to spoil the Huskies' hopes of winning the MacNaughton Cup title outright.
With the victory, Wisconsin secured home ice to open the WCHA playoffs March 15.
St. Cloud State will settle for a co-championship with Minnesota, which beat Bemidji State on Saturday.
Mersch scored his first goal in the first period. Frankie Simonelli also scored for the Badgers (17-12-7, 13-8-7), who got 18 saves from Joel Rumpel.
The Badgers outshot St. Cloud State 31-20.
Andrew Prochno scored both goals for the Huskies (21-14-1, 18-10-1).
The Huskies will have the top seed for the WCHA playoffs.
