MADISON, Wis. (AP) — Staying close to his man on the perimeter, Ethan Happ anticipated Josh Newkirk's pass and maneuvered his 6-foot-10 frame right around Indiana forward De'Ron Davis for a steal.

A fluid big man, Happ converted the turnover into a layup on the break for one of the few easy looks that No. 10 Wisconsin had down the stretch in a 65-60 win on Sunday over the Hoosiers.

Happ scored 20 points and gave his team a defensive spark, while Nigel Hayes added 15 and 10 rebounds.

"When it gets late in the game, you're going to dig deep," Happ said.

Happ was 8 of 10 from the field to help the Badgers (20-3, 9-1 Big Ten) win their seventh straight game and take sole possession of first place in the league. Maryland's loss to Purdue on Saturday allowed Wisconsin to take a one-game lead in the conference over the Terrapins.

The steal with 3:33 left was one of two critical defensive plays by Happ late in the game. About a minute later, Happ blocked a shot, corralled the rebound and called timeout just before falling out of bounds to save the possession.

"Thank goodness there are two sides of a basketball (game). We were able to make up some things on the defensive end," Hayes said.

The 6-8 Hayes joined Happ to give Indiana problems up front. But the Badgers were plagued by mistakes or missed foul shots earlier in the game after building a 12-point lead midway through the first half.

"We wanted to be aggressive, there's no question about that," Indiana coach Tom Crean said.

Indiana (15-9, 5-6) stayed within two or three possessions of Wisconsin for much of the final 30 minutes. Newkirk's two foul shots with 28.6 seconds left got Indiana within 60-57, but Wisconsin went 5 of 6 from the foul line from that point to seal the win.

"When it doesn't go your way, you can still find a way," Wisconsin coach Greg Gard said. "That's what good, experienced teams will find -- find another way to scratch and claw, and get it done."

Newkirk led the Hoosiers with 22 points. Thomas Bryant tried to provide balance but was plagued by foul trouble. He scored nine of his 11 points in the first half.

Wisconsin is poised to make a jump in the next AP Top 25 poll on Monday after six top 10 squads lost on Saturday.

"We know it's hard to win," Hayes said. "The scary thing is, the smaller the number is next to your name, the harder that games get."

The Badgers were most effective when the ball went through Happ in the post or Hayes in the lane. Sloppy ball-handling and a cold stretch from 3-point range helped Indiana get back in the game. Shooting 35 percent from 3-point range for the season entering the afternoon, Wisconsin was held to 24 percent (4 of 17) from behind the arc.

Up next, Wisconsin visits Nebraska on Thursday for an 8 p.m. (CT) game on BTN.
