After trailing 27-25 at the half, the Badgers endured a scoreless drought that lasted over four minutes in the second half. However, with stout defense and turnovers by Michigan, Wisconsin was able to pull away down the stretch.
Wisconsin hounded Michigan into 16 turnovers on the game, the worst mark of the season for the Wolverines.
Wisconsin got nine points each from Nate Reuvers and Aleem Ford, eight points from Brad Davison, and six points from D'Mitrik Trice and Kobe King to round out their scoring.
Michigan had three players reach double figures, including Milwaukee native Jordan Poole.
