West Lafayette, Ind. — Rapheal Davis had just enough going his way to be a nuisance for No. 25 Iowa, but he isn't looking for the credit.

Davis scored 16 of his 24 points in the first half to lead the Purdue Boilermakers to a 67-63 victory over the Hawkeyes on Saturday.

"I made some baskets," Davis said. "But without Basil (Smotherman) playing the game he did, I don't think we win."

Smotherman and A.J. Hammons each scored 13 points for the Boilermakers (12-8, 4-3 Big Ten), who have won two of three.

Smotherman made a couple of free throws with under a minute to play to help keep the Boilers ahead. And after Wednesday's 66-57 loss at Illinois, he wanted to find ways to be effective.

"The practices we had after the Illinois game, we were hustling," Smotherman said. "At Illinois, we really didn't hustle. We made the hustle plays today."

He finished with six rebounds and had no problem throwing himself after loose balls, including one that sent him into the Purdue bench and another on which he landed on the scorer's table.

Mike Gesell scored 18 points and Gabriel Olaseni finished with nine points and 16 rebounds for the Hawkeyes (13-7, 4-3).

Davis made the go-ahead 3-pointer to give Purdue a 65-63 lead with less than a minute remaining and the Boilermakers held on the rest of the way.

Gesell scored to give the Hawkeyes a 63-62 lead at the 1:18 mark before Purdue took the lead for good.

The Hawkeyes played much of the game without Aaron White, who left the game with a right shoulder injury in the first half.

White said it felt like he broke his collar bone when he collided with Smotherman while going after a loose ball at the 15:48 mark.

He returned to the bench when he was knocked in the shoulder again a few minutes after returning to the game.

"I was in a lot of pain," he said. "I tried to go back in after it happened, thinking that if I got back loose it would loosen up and I could help the team. But I reached for the ball and had a popping feeling and pain down my neck, but I'll be alright."

Gesell scored 10 points in a row for Iowa late in the second half, including a shot to make it 62-61 late in the game before he scored to give Iowa the lead.

"In the second half, I was just looking to be aggressive," Gesell said. "I think we did a great job down the stretch. Davis just hit a big-time shot."

Not much has been going Iowa's way lately, starting with Tuesday's 82-50 loss at Wisconsin.

And on Saturday, Purdue took advantage.

The Boilermakers went on an 8-1 run to jump to a 30-20 lead when Smotherman scored on a breakaway dunk with 3:19 remaining in the opening half.

They led by 12 in the first half and had a 34-24 halftime lead.

(At) Penn State 79, Rutgers 51: D.J. Newbill scored 23 points and Brandon Taylor 16 to lead Penn State to its first conference victory of the season. The Nittany Lions (13-7, 1-6), losers of six straight, never trailed after taking a 16-15 lead with just over 10 minutes to play in the opening half. The 28-point spread was Penn State's largest margin of victory since December 2011 against Mount St. Mary's (29).

Shep Garner added 13 points for Penn State, including three 3-pointers. Penn State shot 10 of 20 from 3-point range and its first 12 points were on 3-pointers.

Rutgers (10-11, 2-6) was led by 19 points from Kadeem Jack, the only Scarlet Knight in double figures. Rutgers shot just 10 of 27 in the second half after going 11 of 21 in the first half. The Knights were 3 of 13 from 3-point range.

(At) Minnesota 79, Illinois 71: Andre Hollins helped Minnesota pull away with 17 of his 28 points in the second half. Hollins finished 10 for 15 from the field, including 5 for 7 from 3-point range, and grabbed five rebounds for the Golden Gophers (13-8, 2-6 Big Ten). Carlos Morris had 13 of his 16 points in the first half, Mo Walker chipped in 12 points and 13 rebounds and Nate Mason added 10 points and six assists.

Hollins has 80 points in his last three games, an average of 26.7.

Malcolm Hill and Kendrick Nunn each scored 18 points for the depleted Fighting Illini (13-8, 3-5), who played their third game in the last seven days. Jaylon Tate added 11 points and nine assists, but the Illini ran out of steam down the stretch with a rotation that's only seven deep right now.
