Brock McGinn scored 11:05 into the second overtime to lift the Carolina Hurricanes to a 4-3 victory, eliminating the defending Stanley Cup Champions.
Carolina trailed 2-0, and 3-1 during the game but fought back to advance to the second round for the first time since 2009 and will play the New York Islanders.
They are now 5-0 in Game 7s.
Washington took a 3-2 lead in to the third period, thanks to goals from Andre Burakovsky, Tom Wilson and Evgeny Kuznetsov.
It was Burakovsky‘s first Stanley Cup Playoff goal since he scored twice in Game 7 of the 2018 Eastern Conference Final against Tampa.
Sebastian Aho put Carolina on the scoreboard with a shorthanded goal at 9:51 of the second period, before Teuvo Teravainen and Jordan Staal scored in the second and third periods respectively.
Aho scored his second of the playoffs at 9:51 of the second period, knocking in his own rebound after Braden Holtby failed to glove the puck.
Overtime was difficult for both sides, with the Hurricanes having to kill a penalty after forward Saku Maenalanen was called for a delay of game at 2:02 of the second overtime
Petr Mrazek made 34 saves for Carolina, who were playing their eight Game 7, and Holtby made 38 saves for Washington, who were partaking in their 17th Game 7.
Three Hurricanes players had a multi-point game – McGinn scored one and assisted another, Brett Pesce had two assists, and Jaccob Slavin had three on the night taking his playoffs total to nine.
The result sees both of last years’ finalists out of the competition after the First Round – the Vegas Golden Knights were eliminated in overtime against the San Jose Sharks on Tuesday Night.
Carolina will travel to New York, where they’ll face the Islanders on Friday.
These 2019 Stanley Cup Playoffs mark the first time in NHL history that every division leader has been eliminated in the opening round.
