The Hoosiers (15-12, 5-9 Big Ten) held Wisconsin (23-5, 10-5) to its lowest point production in the first half this season, taking a 29-19 lead.
But Wisconsin outscored Indiana 9-2 over the first 3 minutes of the second half as the shots started to fall. The Badgers shot 26 percent in the first half, they hit 62 percent of their shots in the second. They went 6 of 11 from the 3-point line after making just 1 of 10 in the first half.
For Indiana, it was another blown double-digit lead. This one was more of a slow burn compared to losing to Penn State at home two weeks ago after leading by 12 points with just over 3 minutes to go.
A few late scores helped Indiana finish a respectable 42 percent from the field for the game. But after Indiana's Stanford Robinson converted a three-point play with more than 14 minutes to go, the Badgers went on a 22-5 run to put the game away.
Yogi Ferrell scored 21 points to lead Indiana, while freshman Noah Vonleh added 18.
Traevon Jackson scored 14 points for the Badgers, Ben Brust added 12, Josh Gasser 11 and Frank Kaminsky had 10 to go along with nine rebounds.
Indiana's Hanner Mosquera-Perea ended a two-game suspension after his Feb. 14 arrest for two Class A misdemeanors stemming from a drunk driving arrest. He didn't score in 2 minutes of action.
