STATE COLLEGE, Pa. -- Fifth-ranked Indiana had one of its flattest second halves of the season Monday night against host Penn State in the Bryce Jordan Center.
Still, the end result was another lopsided IU victory, a 74-51 win, the Hoosiers' 10th by at least 20 points this season.
The Hoosiers (14-1, 2-0 Big Ten) were sluggish for much of the final 20 minutes but used a sharp first half and a defense that flustered the Nittany Lions (8-6, 0-2).
Christian Watford led Indiana with 16 points. Cody Zeller had 15 and Jordan Hulls had 14. Ross Travis had 14 points for Penn State, which lost for just the second time at home this season, while Jermaine Marshall had 11.
Indiana sleepwalked out of the halftime locker room, scoring just one point while committing six turnovers in the first four minutes of the period. But Penn State could only shave one point off the Hoosiers' 17-point lead during that stretch.
A fast-break dunk by Zeller, who was 5 of 7 from the field, pushed the lead to 61-41 with just under eight minutes to play, sending many Penn State fans to the exits.
The Hoosiers wasted little time taking control of the game, jumping out to leads of 15-3 and 31-13. Indiana shot better than 50 percent for much of the first half, settling at 52 percent before the break, and the Hoosiers were able to generate easy baskets by forcing several Penn State turnovers with full-court pressure.
The Nittany Lions, who got nine first-half points from Marshall, could not put back a number of offensive rebounds at point-blank range.
Foul trouble, as it has often been for Penn State, was an early problem. Forward Brandon Taylor picked up two fouls in the first four minutes, and he played just seven minutes in the first half. Reserve Jon Graham had three personals in the half.
Watford had 13 points and Hulls had 10 at the break. Indiana, which hit six 3-pointers and 10 of 13 free throws in the first 20 minutes, took a 44-27 lead into halftime.
NOTES: Indiana, which leads the nation in scoring, has reached 90 points or more in six games this season. ... Indiana is the only Big Ten team to play its first two conference games on the road this season. ... Penn State guard D.J. Newbill is the Big Ten's only player to rank in the conference's top 15 in scoring, rebounding and assists.
