D.J. Newbill scored 19 points on 6-of-18 from the field for No. 13 seed Penn State (18-16), which lost for the first time in four games despite committing only three turnovers – half of its previous season low.

After a back-and-forth opening six minutes, Newbill knocked down the second of back-to-back 3-pointers and Brandon Taylor scored five straight points as Penn State held Purdue to three field goals from Hammons over a 9 1/2-minute stretch to build an 11-point lead. Hammons scored the rest of his 14 first-half points over the remaining 3:35 and the Boilermakers closed within 37-32 at intermission on a late triple by Kendall Stephens.

Purdue scored 10 of the first 14 points of the second half to pull ahead by one and answered the Nittany Lions’ subsequent 9-2 burst with the next 13 points until Newbill drained a long 3-pointer over Hammons to make it 57-53 with 40 seconds remaining, ending an 8 1/2-minute scoreless drought. Newbill added four free throws and late bucket over the remainder of the contest, but the Boilermakers countered with six foul shots to seal it.
