Penn State dropped its second straight in-conference matchup Friday night.
The Nittany Lions moved to 10-8 on the season after dropping the first game of a two-game series to a struggling Wisconsin 4-1 in Madison.
The first period ended scoreless, but Wisconsin was able to take control of the contest in the second period.
The red and white scored three goals in the second 20 minutes, with two coming on a single three-minute power play.
Penn State struggled to find offensive production for most of the night, but junior forward Tyler Gratton was able to cut the lead to 3-1 in the third, but it wasn’t enough for Penn State.
