TEMPE, Ariz. — Gavin McKenna had two first-period assists in his Penn State debut, helping the Nittany Lions beat Arizona State, 6-3, on Friday night. McKenna left the Western Hockey League champion Medicine Hat Tigers to play for Penn State after the NCAA lifted its ban on Canadian Hockey League players. He was the WHL’s player of the year last season, finishing with 41 goals and 88 assists in 56 regular-season games. After Arizona State took a 3-2 lead in the second period, Matt DiMarsico had a hat trick in the third for Penn State, the last into an empty net. Cerrato also had a late goal for his fifth point of the night.
