WEST LAFAYETTE, Ind. -- Three years removed from back-to-back losing seasons, No. 16 Purdue is back on top in the Big Ten Conference.

Caleb Swanigan had 21 points and 10 rebounds, Dakota Mathias added 19 points and seven rebounds and No. 16 Purdue clinched at least a share of the Big Ten championship with an 86-75 victory over Indiana on Tuesday night.

Vince Edwards added 15 points and seven rebounds for Purdue.

The Boilermakers now have 23 Big Ten championships, one more than Indiana. The victory also clinched the No. 1 seed in next week's Big Ten tournament in Washington, D.C.

"There were a lot of good things going on out on the court tonight," Purdue coach Matt Painter. "We honored our seniors and won a championship. I can remember not long ago that we were in last place in the Big Ten.

"Three years later with a really good junior class and with Caleb, we won it. We added guys who wanted to win and guys who have lots of skill."

Purdue (24-6, 13-4) will claim the title outright by winning Sunday at Northwestern, or if Wisconsin loses either of its final two games -- at home Thursday against Iowa or at home Sunday against Minnesota.

"This feels really good," Mathias said. "To come this far and improve this much is quite an accomplishment. For me, I didn't think I was cutting very hard in our loss Saturday at Michigan, so in the first half tonight, I wanted to do that and get open. I did, and I made shots."

Indiana, which has lost eight of 10, got 16 points from James Blackmon Jr. and 13 each from Josh Newkirk and Devonte Green.

"This is a close team that has played well on the road," Swanigan said. "I think that's why we achieved this."

A three-point play by Swanigan and a 3-pointer from P.J. Thompson gave the Boilermakers a 51-41 lead with 15:55 remaining. Indiana (16-14, 6-11) closed within 57-51, but Purdue countered with an 11-4 run to take a 68-55 lead with 7:28 left.

After Indiana big man Thomas Bryant fouled out with 5:45 remaining, Purdue's Vincent Edwards made a 3-pointer and Ryan Cline hit a driving runner to give the Boilermakers a 76-60 lead with3:42 left.

Purdue outscored Indiana 28-13 from the free throw line and limited the foul-plagued Bryant to eight points and five rebounds.

"We outscored them in the paint (30-24), but we didn't shoot a free throw until 11 minutes were left in the game," Indiana coach Tom Crean said. "I think Mathias is the key to their team, and he was the key to the game tonight.

"We did a good job on him at our place, but we lost him a couple of times tonight, and he hurt us. It's obvious the free throw difference hurt us. I am happy for Matt. He is a great coach with a great program."

Mathias' 17 first-half points led Purdue to a 40-32 lead through 20 minutes, although Indiana scored the final seven points of the half after trailing 40-25 on Cline 3-pointer with 2:41 remaining.

Mathias sank 7 of 9 shots from the field in the first half, including 3 of 5 from beyond the arc. He also had five rebounds, two steals and no turnovers before intermission.

Newkirk led Indiana with seven first-half points and Green added six.

The Hoosiers had 11 turnovers during the first 20 minutes but outrebounded the Boilermakers 19-13.
