Lars Eller got the last stick on a puck that bounced off him and Columbus defenseman Zach Werenski before rolling past Sergei Bobrovsky, and Washington got the 3-2 victory nine minutes into the second overtime Tuesday night.
The Capitals won at Nationwide Arena after Columbus won the first two games -- both in overtime -- in Washington. It was the Capitals' turn to prevail in OT, this time on the Blue Jackets' home ice, to pull to 2-1 in the best-of-seven series.
"It means a ton, a win like this after playing for that long," Eller said. "I'm sure they feel a lot more tired in that room than we are feeling right now. It gives you a lot of energy. It's going to be a battle again in Game 4."
"We got some good fortune, but we also executed and we were committed today," Capitals coach Barry Trotz said.
Game 4 is Thursday night back here with Game 5 set for Washington on Saturday.
"We got a break, it's what we needed," Capitals forward John Connolly said. "You need breaks, every team is so good now, you need to keep pressing and pressing. "
Panarin knotted the score 4:12 into the third period after he and Cam Atkinson went back and forth with pinpoint passes before he swiped it past Holtby from the left circle.
That's the way it stayed until the second overtime.
After a scoreless first period, Wilson got credit for the first Washington goal when he deflected Matt Niskanen's rising shot 5:52 into the second. The Blue Jackets got a break two minutes later when a goal by Connolly was waved off after a video replay showed he was offside bringing the puck down the ice.
Dubois tied it with 8:42 left in the second when he rifled a shot past Holtby's glove from the right circle.
After feasting on the power play in the first two games, the Blue Jackets failed to score on four tries with a man advantage. The Capitals whiffed on three of their four power plays.
"It's a hell of a series," Columbus coach John Tortorella said.
