MADISON, Wis. (AP) — In a season of upheaval, Wisconsin has finally found its groove.

The frontcourt is leading the way.

Nigel Hayes scored 31 points, Ethan Happ added 25 and the Badgers snapped No. 19 Indiana's 12-game winning streak with an 82-79 victory in overtime on Tuesday night.

"It wasn't the prettiest of fashions, but they kept finding a way, they kept battling," interim coach Greg Gard said.

The Badgers (12-9, 4-4 Big Ten) have won three straight games, each by six points or less, after having lost three straight by five points or less.

They're learning how to win close games, and Gard said that was in part due to the chemistry that has developed of late.

It can be quite a shock when a team loses its coach at midseason, like what happened to the Badgers when Bo Ryan retired last month.

"The chemistry and culture in the locker room has grown tighter and tighter," Gard said. "The cohesiveness and togetherness and how these guys are growing together is something that makes me extremely proud to be their coach."

Wisconsin missed several chances in the closing minutes of overtime to put the game out of reach after Bronson Koenig and Jordan Hill each went 1 of 2 at the free throw line.

Kevin "Yogi" Ferrell's 3 with 5 seconds left pulled the Hoosiers within 80-79 before Hayes stretched the lead back to three with two free throws.

But Indiana (17-4, 7-1) never had a chance to give Ferrell one last shot to tie after Hayes tipped away OG Anunoby's inbounds pass as time expired.

Ferrell finished with 30 points on 12-of-20 shooting. He was 5 of 6 from 3-point range.

"All things considered, I'm proud with the way my team battled," Indiana coach Tom Crean said. "But at the same time, there were too many mistakes to win the game."

Indiana had 19 turnovers and 31 fouls, giving Wisconsin 19 more opportunities at the free throw line.

Wisconsin extended its home winning streak against Indiana to 14 games.
