Gophers at Penn State. 5:30 p.m. Friday; 7 p.m. Saturday (BTN, 1500-AM both games)

Preview: The No. 5 Gophers (18-8-2, 9-3 Big Ten), in first place in the Big Ten standings with 27 points, open a crucial four-game stretch in league play with a series at third-place Penn State. The ninth-ranked Nittany Lions (18-6-2, 7-4-1) were swept by the Gophers two weeks ago at Mariucci Arena and have cooled considerably after rising to the top of the national rankings for the first time in program history. Penn State is 5-4-1 in its past 10 games, while the Gophers are 7-3. The Gophers, who are shooting for their fourth consecutive Big Ten title, play second-place Wisconsin at Mariucci Arena next weekend.

The game will feature the two top-scoring defensemen in the Big Ten: the Gophers’ Jake Bischoff (24 points) and the Nittany Lions’ Trevor Hamilton (23).
