Kyle Turris scored at 2:42 of overtime to give Ottawa a 3-2 victory Wednesday night, the Senators' second extra-period win in the Eastern Conference series.
"I've just lived every kid's Stanley Cup dream," Turris said. "It was a great play by O'Brien. It was kind of a long shift in our zone and right when he got it I was actually thinking of changing, but I saw it was a 2-on-2. I just tried to use the (defenseman) as a screen to get it on net."
In Game 2 in New York, Chris Neil scored in overtime for Ottawa.
"It's frustrating to lose in overtime, but there were some good things," Rangers coach John Tortorella said. "I think we still need some more guys involved, but it was two overtimes, the series is 2-2 and we're going back home."
The Senators ended a seven-game home playoff winless streak.
"We've got so much character in this room and that led us through," Turris said. "We rallied and tried to put pressure on them and chip away at their lead. It's exciting. It's a confidence builder and something to move forward on."
Game 5 is Saturday night in New York.
"They had a good second period and we made it a little tougher on ourselves taking all the penalties," said Lundqvist, who made 28 saves. "They got some confidence on the power play and were moving the puck. They felt good about themselves and building their game from there. We regrouped and played really well in the third and did some good things but it wasn't enough."
"We've had good starts and they're a good team, but we just need to find a way to win in overtime. That's what it comes down to," Rangers defenseman Marc Staal said. "We took a string of penalties in the second and that hurt our momentum a little bit. They've got a good power play and we've got to stay out of the box. We let them back in, but I thought we rebounded and had a good third, but we just couldn't find a way in overtime."
Both teams had great opportunities to take the lead in the third period. Ottawa created a flurry of chances in the final minute, but was unable to beat Lundqvist. New York's best opportunity came with just over 5 minutes remaining when Nick Foligno was called for tripping, but the Senators killed the penalty.
"I thought (Anderson) was our best player," Ottawa coach Paul MacLean said. "I thought he was outstanding. I thought he showed great leadership and competitiveness for the team and thought he really tried."
The crowd of 20,340 at Scotiabank Place gave Ottawa a standing ovation for more than 3 minutes after the goal.
"That was huge," Carkner said. "That's momentum in the playoffs. The crowd was great. They were roaring after that and the guys got some energy on the bench and we continued to play our game."
With Ottawa on the power play late in the period, Staal caught Spezza in the face with a stick and then gave him an elbow to the head and no penalty was called. Spezza was hunched over when the hit took place, and he went down hard and left the game. He returned for the start of the third.
Ottawa tied it on the same power play, with Gonchar's shot from the top of the faceoff circle making it through traffic and past Lundqvist with 2:10 left in the period.
After going 1 for 11 on the power play in the first three games, the Rangers scored twice with the man advantage in the first period. Stralman opened the scoring at 49 seconds, and Callahan was left all alone at the side of the net to bang in a rebound at 6:10.
"Any time you have a lead, you don't want to lose it. But it doesn't matter right now," said Richards, who assisted on both New York goals. "It's over and it's time to move on to the next one. We'll take a look at it and build on the stuff we did well and see where we need to improve."
