Jordan Bohannon hit the game-winning three-pointer with 9 seconds left, and Iowa capitalized on No. 22 Wisconsin's sloppy final few minutes with a 7-0 run to beat the Badgers, 59-57, on Thursday night.
The Badgers (22-8, 11-6) lost their third straight game, going scoreless for the final 3:12. Iowa forced turnovers on consecutive Wisconsin inbounds passes in that stretch, converting each mistake into baskets to set up Bohannon's game-winner.
After Ethan Happ missed two free throws that could have sealed the win for Wisconsin, Iowa's Peter Jok missed a jumper in the lane.
But Cordell Pemsl corralled the offensive rebound and Bohannon hit the three-pointer from the left wing, stunning the crowd at the Kohl Center after Wisconsin led by nine with 4:15 left.
