The Indiana Hoosiers beat previously unbeaten Wisconsin 75-72 at Assembly Hall Tuesday night.
Yogi Ferrell had 25 points to lead all scorers. Stanford Robinson and Will Sheehey added 13 for the Hoosiers.
The third-ranked Badgers (16-1, 3-1 Big Ten) were trying to become the first team ever to win 13 straight games over the Hoosiers (12-5, 2-2).
Wisconsin started the night as one of Division I's four remaining unbeaten teams and it looked like it would stay that way when the Badgers took a 10-point lead with 13:27 to play.
But the Hoosiers, playing their best game of the season, answered with 12 straight points to take a 54-52 lead with 9 minutes left.
Indiana led 70-65 with 2:03 remaining but still had to fend off Wisconsin's late challenge. Ferrell made two free throws with 18.3 seconds left to give Indiana the three-point lead and both of Wisconsin's potentially tying 3-pointers came up short.
Traevon Jackson led the third-ranked Badgers with 21 points in the loss.
