WEST LAFAYETTE, Ind. (AP) -- Jaraan Cornell's ugliest shot was the one that hurt Indiana the most.

	Jaraan Cornell, who scored 25 points, rips down one of his six rebounds.

"It wasn't luck," Cornell said of the crucial shot. "I just had to adjust my body. I was backpedaling, trying to get open, and I saw Michael Lewis come out. He got a hand on one of my shots earlier, and I had to get more arc in it than normal and it just caught the glass.

"It definitely was one of my better games," said Cornell, whose scoring offset the 27 points by Indiana's A.J. Guyton.

"Their role is to get A.J. the ball, and they do a good job of it. We just had to counter the attack. With the seniors on the court, we didn't get discouraged, and I had a chance to get some nice looks."

The victory lifted Purdue (13-5, 4-1) to a first-place tie in the Big Ten.

"We're OK when we're patient," Purdue coach Gene Keady said. "They're playing hard on defense and running the offense with some smart decisions now. The fact they came back like this makes me feel like coaching is worthwhile."

Greg McQuay and Robinson added baskets, and Purdue hit six free throws to pull away in the final minute. Brian Cardinal, who had three of the late free throws, added 21 points and 11 rebounds for Purdue and Robinson scored 15.

Lewis added 13 points and Kirk Haston had 12 for Indiana, which shot 56 percent to Purdue's 45 percent but was hurt by 14 turnovers and poor blocking out on the defensive boards.

"When we got the lead, we had done a pretty good job coming from five down at the half. Then they made some really good offensive rebound plays," Indiana coach Bob Knight said.

"If anything really hurt us, it was the combination of their offensive rebounding and our poor blockouts," Knight said. "Their starting front line got 16 offensive rebounds and ours got two. That's just too big of a differential in a tight ball game."

Indiana outrebounded Purdue 33-32, but Purdue got 10 more shots at the basket in part because of its 19-10 advantage in offensive boards.

"We knew one of their weaknesses was rebounding, so we worked on that all week," Cornell said. "It was a matter of having the desire to do that, and we did."

Indiana has lost eight of the past 10 games in one of college basketball's most heated rivalries, and the Mackey Arena crowd threw repeated taunts at Knight. Several dozen fans in one student section wore bright orange hunting vests and caps, with one holding a sign, "Don't shoot, Bobby, we are unarmed," referring to an incident in October when Knight accidentally shot a hunting partner.

The Hoosiers weren't distracted, however, and three early baskets by Haston helped them to a 12-7 lead before Purdue took control. Cornell had eight points, including two 3-pointers, during a 17-4 run over the next six minutes.

Cornell's third 3-pointer put Purdue up 30-20, the biggest lead of the game.

Indiana closed within 35-34, but Robinson scored, stole the ball and fed Carson Cunningham on a fast break to push Purdue's lead back to five points. Offsetting baskets by Jeff Newton and Robinson gave the Boilermakers a 41-36 lead at halftime.

The second of three 3-pointers by Guyton cut Purdue's lead to two points, then a baseline drive by Lewis tied the game 56-56 midway through the second half. Indiana matched its biggest lead at 63-58 on a basket by Haston.
