Ottawa: Colin Greening scored 7:39 into double overtime as the Ottawa Senators rallied for a 2-1 victory over the Pittsburgh Penguins that cut their deficit in the Eastern Conference semi-final series to 2-1 on Sunday night.

Tyler Kennedy scored late in the second period to give the Penguins a 1-0 lead, which stood up until Daniel Alfredsson equalised with 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.

The Senators and Pittsburgh resume their semi-final series at Ottawa on Wednesday.

In the other play-off match on Sunday, Johnny Boychuk broke the deadlock midway through the second period and Boston scored two goals in the third to beat the New York Rangers 5-2 and take a 2-0 lead in their series.

Boychuk’s third play-off goal made it 3-2 at 12:08 of the second. Brad Marchand and Milan Lucic stretched the Bruins’ lead in the final period.

Games 3 and 4 of the best-of-seven series will be played in New York.
