Purdue improved to 13-1 at home and extended its winning streak to eight games as the Boilermakers held on to a share of the lead in the Big Ten.
Penn State was led by senior Mike Walker who hit three second half threes on his way to 12 points. Freshman Talor Battle added 10 for his seventh double-digit scoring game in the Big Ten and Danny Morrissey had 11.
Purdue was led by freshmen Robbie Hummel and E'Twaun Moore. Hummel posted 17 points and Moore 16.
Penn State shot 47 percent from the floor, but committed 18 turnovers in the game off of which Purdue scored 19 points. The Lions struggled from the free throw line as well hitting just 5-of-14.
Penn State played all but six minutes of the second half without standout junior Jamelle Cornley who left the game after hitting his mouth on the floor and needed stitches following the game.
A Mike Walker three had Penn State within five, 46-41, with 10:58 to play, but Boilermakers used a nearly five minute scoreless stretch from Penn State to break open a close game and open up a 13-point lead, 56-43, with just over seven minutes to play. Penn State cut the lead back to 10 twice on Walker threes, but Purdue responded each time with a three from Marcus Green and a three from Hummel. Purdue eventually extended the lead to as much as 17 after a Chris Kramer dunk with 40 seconds to play.
Penn State trailed 33-30 at the half after a late 7-0 Nittany Lion run closed as much as a 10-point first half Boilermaker lead. Purdue used an early 7-0 run to take a 9-2 lead and eventually extended it to 14-4. Penn State got a pair of threes from Danny Morrissey in an 8-0 run of its own and closed the lead to 14-12 on a Jeff Brooks jumper as Purdue went scoreless for nearly five minutes.
Penn State tied the game at 17-17 on an Andrew Jones bucket and took the lead, 21-19, on a Cornley lay-in off a nice Brooks feed with 6:05 to play.
Purdue then went on a 10-0 run getting a pair of threes from Moore to take a 19-21 lead with 3:22 to play. Following a Stanley Pringle runner that ended the Purdue run, the Boiler stretched the lead to 33-23 on a bucket from JaJuan Johnson with 2:01 to play.
Penn State responded with a three from David Jackson off a nice Cornley pass, a Cornley bucket and a pair of free throws from Jones to slice seven points off the lead and go to the locker room down 33-30.
Morrissey and Cornley both had eight for the Nittany Lions in the half. Moore had 10 and Hummel nine for the Boilermakers. Penn State shot 57 percent from the floor in the half including 4-of-6 from three while holding Purdue to 41 percent and out-rebounding the Boilers 15-12. However, 12 first half Nittany Lion turnovers and 14 Purdue points off them kept the Boilers in front.
Penn State will continue a stretch of four of five games on the road Saturday at Michigan (5-17; 1-9 Big Ten), which fell, 65-55, at Ohio State Tuesday. Saturday's game is scheduled for a 4:00 p.m. tip on the Big Ten Network.
