The Wolverines (18-7, 10-3 Big Ten) cut an 18-point deficit to three in the second half, but Kaminsky personally went on a 7-2 run after that, helping Wisconsin regain control. The Badgers (21-5, 8-5) have won four straight — and they committed only two turnovers.
Caris LeVert scored 17 of his 25 points in the second half for Michigan.
Sam Dekker had 15 points for Wisconsin.
The Badgers led 34-19 at halftime after holding Michigan without an assist in the first half.
Michigan entered the day tied atop the Big Ten with rival Michigan State — the Spartans played later Sunday against Nebraska. Michigan now has a week off before hosting Michigan State next Sunday.
The Wolverines won at Wisconsin last month, but they looked out of sorts from the start in the rematch. The Badgers opened the game with a 12-2 run, and Michigan's normally fluid offense was totally out of rhythm. Wisconsin forced seven turnovers in the first half and hardly allowed an open shot.
It was 34-16 near the end of the half, and as the game progressed, the Wolverines seemed to become increasingly reliant on long jumpers from just inside the 3-point line.
They made a decent number of them, and LeVert's two free throws capped a 9-0 run that made it 52-49. Then Kaminsky went back to work. He scored inside, drove for a layup and then added a three-point play that made it 59-51 with 3:48 remaining.
Kaminsky later stepped outside and made a 3-pointer to push the lead to 13 at 65-52. He finished 11 of 16 from the field against a Michigan front line that is without Mitch McGary, who is recovering from a back injury.
Wisconsin hit a rough patch after a 16-0 start, but now the Badgers again look like one of the Big Ten's best teams. This was the second time this season they've committed only two turnovers in a game.
Wisconsin has now won five of its last six in Ann Arbor.
Josh Gasser had 13 points for Wisconsin. Nik Stauskas scored 11 for Michigan and Glenn Robinson III added 10.
Wisconsin is now 9-2 away from home this season, and this may have been the most impressive road win for the Badgers.
Wisconsin beats Michigan 75-62
