The victory moves the Gophers into the quarterfinals on Thursday where they will meet Ohio State.
Joey King picked up the slack for Minnesota. He knocked down 6-of-9 three-pointers and scored a game-high 20 points in leading the Gophers to the victory.
Carlos Morris added 16, Nate Mason chipped in 15 and Maurice Walker had a quiet double-double with 10 points and 10 rebounds. DeAndre Mathieu also was solid. He contributed eight points and eight assists off the bench.
Hollins, who averaged more than 14 points a game in the regular season, was 0-for-6 from the floor.
Minnesota hasn't won back-to-back games in the Big Ten Tournament since 2010. They will need to win four more games over the next four days to qualify for the NCAA Tournament.
