Claude Julien wanted his Bruins to play more aggressively in the third period. The Boston coach got his wish with the help of some shaky defense by the New York Rangers on Sunday in Boston.
A rare rough day for goalie Henrik Lundqvist certainly helped, too.
Brad Marchand and Milan Lucic scored in the final period after Johnny Boychuk broke a tie in the second, Lundqvist gave up more than four goals for the first time in 152 games, and Boston beat New York, 5-2, to take a two-goals-to-none lead in the Eastern Conference semifinal series.
"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."
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 minutes, 8 seconds.
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.
New York's best period was the second, when it outshot Boston, 16-9. The Rangers then allowed two goals in the third.
"We gave it to them," said Lundqvist, last year's Vezina Trophy winner as the NHL's top goalie. "I thought we played great. I didn't think they had to work really hard to get a couple of goals there. We just made it really tough on ourselves."
Colin Greening scored 7:39 into double overtime, and the host Ottawa Senators rallied for a 2-1 victory over the Pittsburgh Penguins that cut their series deficit to 2-1.
Daniel Alfredsson got Ottawa even at 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.
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.
