The Cats, on the heels of consecutive losses to Creighton and Ohio State, started out sluggish again, as they shot just 36.8-percent from the field and were out-rebounded 25-15 by the Nittany Lions at the break.
However, NU turned around in the second half to shoot a blistering 71.4-percent from the floor and out-rebound PSU 13-11. The Cats also shot 60-percent from three in the second half, helping to end a drought of poor shooting from beyond the arc.
John Shurna got back on track, scoring-wise, after struggling against Creighton and Ohio State, as he scored 17 points to finish third on the team in scoring behind Drew Crawford's 21 and Dave Sobolewski's career-high of 20.
NU struggled to score down low, as center Luka Mirkovic has just four points and Davide Curletti had none off the bench. The Cats struggled in general off the bench, with just six total points, all coming from Alex Marcotullio.
Tim Frazier led Penn State with 16 points, and Jermaine Marshall and Cammeron Woodyard joined him in double-figures, with 14 and 11 points, respectively.
However, the Nittany Lions also struggled to score down low — a problem that has plagued them all season — as lone starting forward Billy Oliver had just two points.
Like Northwestern, PSU struggled to score in the first half, shooting 25.8-percent from the floor, and couldn't keep up with NU after the break, despite shooting 45.5-percent from the floor over the final 20 minutes.
The loss dropped the Nittany Lions to 8-7 on the season and 0-2 in the Big Ten. They face Purdue at home on Thursday, while the Wildcats play in-state rival Illinois Wednesday in Evanston
