The second-seeded Badgers (26-6) have won nine of 10 and will face No. 22 Michigan State or 11th-seeded Northwestern in Saturday's semifinals.
Minnesota (20-13) was led by Deandre Mathieu with 18 points and Joey King with 14 but lost for the sixth time in their last eight tries against the Badgers. The Gophers now must wait to see if the NCAA tournament selection committee thinks they have done enough to get one of the precious 36 at-large bids.
The Badgers scored the last eight points of the first half to take a 34-22 lead, then fended off Minnesota's second-half charge with 10-2 run that made it 50-33. The Gophers couldn't get closer than 10 the rest of the game.
