OTTAWA - Colin Greening scored 7:39 into double overtime, and the Ottawa Senators rallied for a 2-1 victory over the Pittsburgh Penguins that cut their series deficit to 2-1 on Sunday night.
Daniel Alfredsson got Ottawa even 1-1 by scoring a short-handed goal with 29 seconds left in regulation just after the Senators pulled goalie Craig Anderson for an extra skater.
"We were just calm," Anderson said of the Senators' mood heading into overtime. "We had tied it up. We had momentum. We felt like the fans really rallied behind us.
"Going into overtime, we knew we just had to build off the momentum and keep the pressure on."
Anderson made 49 saves, including 18 after regulation. Tomas Vokoun stopped 46 shots for Pittsburgh and took his first loss (4-1) since taking over for No. 1 Penguins goalie Marc-Andre Fleury.
Game 4 of the Eastern Conference semifinal series will be in Ottawa on Wednesday.
Tyler Kennedy scored with just over a minute to play in the second period to give the Penguins a 1-0 lead. That stood up until Alfredsson tied it in the closing seconds of the third.
"Just praying that we get something to the net," Anderson said of the tying goal. "We practice that drill all the time in practice. Guy drops it off and goes to the net.
"It was just the way we practiced. Alfie is one of the best guys in the game. We want the puck on his stick at all times."
Ottawa forward Jason Spezza, who hadn't played since Jan. 27 - after undergoing back surgery to repair a herniated disc - lined up alongside Milan Michalek and Cory Conacher.
• Bruins 5, Rangers 2: In Boston, Johnny Boychuk broke a tie midway through the second period, and the Bruins scored two goals in the third to take a 2-0 lead in the Eastern Conference semifinal series.
Boychuk put a 40-foot shot from the right inside the near post for his third playoff goal to make it 3-2 at 12:08. Brad Marchand, whose overtime goal won the opener, and Milan Lucic stretched the Bruins' lead in the final period.
Boston never trailed as rookie Torey Krug scored the first goal before Ryan Callahan tied it. Gregory Campbell made it 2-1, and New York pulled even again on Rick Nash's goal.
"Some games you're going to get more goals, some maybe less," Bruins captain Zdeno Chara said, "but the important thing was we were trying to focus on playing hard until the end."
Games 3 and 4 of the best-of-seven series will be played in New York on Tuesday and Thursday, respectively.
New York goalie Henrik Lundqvist, last year's Vezina Trophy winner, had his second straight tough game after posting consecutive shutouts in Games 6 and 7 of the first round against Washington when the Rangers faced elimination.
"We gave it to them," said Lundqvist, last year's Vezina Trophy winner as the NHL's top goalie
Tuukka Rask was solid again for Boston, stopping 35 shots.
