MADISON, Wis. (AP) _ Christian Hackenberg threw for 339 yards and four touchdowns, and Penn State pounced on a slew of blunders before holding off a late rally to upset No. 14 Wisconsin 31-24 on Saturday.
Hackenberg, a freshman, showed the poise of a veteran in dissecting a tough defense. Eugene Lewis caught two touchdowns, including a 59-yarder for a 17-point lead with 13 minutes to go.
The Nittany Lions (7-5, 4-4 Big Ten) secured a statement win against a team that had been dominant all year at home. Joel Stave threw for three touchdowns for Wisconsin (9-3, 6-2), though Penn State capitalized on second-half interceptions, turning one into Lewis' long TD.
The Badgers got within a touchdown late, but were picked off in the end zone with 1 second left.
