STATE COLLEGE, Pa. (AP) — A rally to close the first half enabled Purdue to ultimately pull away from Penn State in the second half as the Boilermakers evened their Big Ten Conference record at 5-5 with a 58-49 victory Tuesday night over Penn State.

The Nittany Lions (8-14) are now 0-10 in conference play despite outrebounding the league's top rebounding team 42-37 and watching Purdue (12-11) shoot 0 for 10 from 3-point range.

Ronnie Johnson scored 16 points, 12 of them in the second half for Purdue. A.J. Hammons, a 7-foot freshman center, added 15 for the Boilermakers, who took control of a back-and-forth game with about 9 minutes to play after a first-half rally from a nine-point deficit.

"We need to keep it simple," Purdue coach Matt Painter said. "We get ahead of ourselves a bit too much and we force and we try to take on the world."

Both coaches agreed on two things: Johnson was the spark behind the Boilermakers' victory and the game turned during the final 4 minutes of the first half and opening 4 minutes of the second.

"We played a great 32 minutes," said Penn State coach Patrick Chambers. "We had a couple of great looks and the shots just didn't fall."

The Boilermakers (12-11) struggled through shooting woes, going 20 for 49 overall. But it was considerably better than Penn State's 19 for 62 (30.6 percent) performance.

Combined, the two teams were 2 for 30 from 3-point range.

Johnson was 7 for 12 from the field and also managed four defensive rebounds.

Penn State's leading scorers, D.J. Newbill and Jermaine Marshall, average 18 points per game but Newbill had 17 and Purdue limited Marshall to just seven.

"If Jermaine has an average night maybe we're sitting here with a win," Chambers said. "He had a tough day, but he's doing everything he can for us."

Purdue's game plan, Painter said, was to "not let Penn State get any action off the ball screen with their four man. So we switched a lot (and) we wanted to make sure he (Marshall) didn't get an angle. We wanted to keep the ball out of his hands."

Both teams struggled from the perimeter, Painter said, and 11 of Hammons' 15 points came from the free-throw line (11 for 12).

Purdue and Penn State had been on opposite schedules as the Boilermakers were playing their fifth game in 13 days while Penn State was involved in just its second game in 10 days with a four-day break around each game.

Purdue struggled early but found the energy to close the first half with a flurry.

Penn State tied the game at 31 behind baskets by Newbill and Ross Travis but Purdue quickly went on an 18-6 run, building a 49-39 lead and forcing a Penn State timeout.

Newbill scored six straight points for Penn State to breathe a little life into the Lions but, Sasa Borovnjak (5:56) and Jon Graham (4:53) fouled out as Purdue led 52-45.

"It's real simple," Chambers said. "When you go through adversity and challenges, when you're losing, it's really easy to start pointing fingers and not stick together.

"You've got to have each other's backs, we have to stick together through thick and thin. Maybe we won't see that but you're going to see it in the future because that's how this program is going to handle it."
