Wilson cut it to 4-1 at 10:32 of the third period with a twirling forehanded shot from the bottom of the left circle that went through Carolina defenseman Brady Skjei's legs.
But the Andersen and the Hurricanes locked it down from there to put the finishing touches on one of the most memorable nights in team history.
"The weather was unbelievable," Staal said, "the venue and the lights, it was just really cool and something I'll never forget being a part of. Just an amazing night."
NOTES: Capitals forward Lars Eller played his 926th NHL game, the most among Denmark-born players. He passed Frans Nielsen. … The Hurricanes are the 15th team to win in their first outdoor game. … North Carolina is the ninth U.S. state to host a Stadium Series game (California, Colorado, New York and Pennsylvania twice each; Illinois, Maryland, Minnesota and Tennessee once each). … Necas has 12 points (five goals, seven assists) in his past 11 games. … Kotkaniemi has goals in back-to-back games and three in his past four. … Hurricanes video coach Chris Huffine, who has been with the team since it arrived in North Carolina from Hartford, Connecticut, in 1997-98, joined the coaching staff on the bench for the third period at the request of Brind'Amour. Huffine typically watches and documents the games from a video room, never from the bench. … It was 43.5 degrees at puck drop.
