Minnesota State Mankato scored three-power play goals in a penalty-filled second period to defeat host Alaska 6-1 on Friday night and clinch the MacNaughton Cup outright. This is the fourth time in five seasons the Mavericks have won the trophy, which goes to the WCHA regular-season champion.

There were 100 penalty minutes handed out and five ejections during that middle period.

Already ahead 1-0, the Mavericks scored three goals in 1 minute, 45 seconds on a major penalty called on the Nanooks at the start of the second for slashing. Parker Tuomie got the first of those goals at 2:29, followed by goals from Reggie Lutz and Marc Michaelis.

Michigan 4, No. 6 Ohio State 2: Michigan delayed Ohio State's celebration of a Big Ten regular-season title for at least one day, beating the visiting Buckeyes 4-2 on Friday night at Yost Arena with three goals in the third period.

No. 6 Ohio State needs just one win to clinch its title, but the Buckeyes have lost three in a row — they were swept at home by the Gophers last weekend. Nolan Moyle of the Wolverines tied the score at 2-all at 9 minutes, 30 seconds of the third and then got the game-winner at 16:49.

Mason Jobst and Tanner Laczynski had the OSU goals.

Strauss Mann had 29 saves for Michigan, Sean Romeo 21 for Ohio State.

No. 19 Penn State 8, Wisconsin 2: Denis Smirnov had two goals and two assists and Brandon Biro two goals as the host Nittany Lions routed the Badgers. It was 2-all when Smirnov got his second goal at 13:51 of the second to put Penn State ahead for good. Two Wisconsin goalies combined for 48 stops.

No. 15 Bowling Green 3, Bemidji St. 1: The Falcons took a 2-0 lead early in the second period and, with Ryan Bednard making 20 saves, that was enough goals to beat the host Beavers. Alex Ierullo scored Bemidji State's goal.
