Arizona State saw its third period lead, as well its biggest win in program history vanish on Friday night, due to late magic from the Penn State offense.
But it was able to pull out the victory in the end as Johnny Walker scored the overtime winner to give the Sun Devils a 4-3 win and hand the Nittany Lions their first loss of the season.
Coming into this series, the Sun Devils had never beat a Big Ten team, nor had they beaten a a top-15 team.
Arizona State again challenged the Nittany Lions, but this time they came out on top.
