BOSTON -- The Boston Bruins clinched a berth in the Stanley Cup Playoffs for the first time in three seasons with a 4-0 win against the Tampa Bay Lightning at TD Garden on Tuesday.
The Bruins (44-30-6) are tied with the Ottawa Senators for second place in the Atlantic Division. The Senators defeated the Detroit Red Wings 2-0 and have one game in hand. The Toronto Maple Leafs trail the Bruins and Senators by one point after a 4-1 loss to the Washington Capitals.
"Obviously a new feeling for me," Bruins forward David Pastrnak said. "I'm really enjoying it, it's a lot of fun and it's exciting. Now we've got ourselves in a spot we can actually fight for home ice and a good spot in the playoffs. We can play a little more relaxed knowing that we made it and it's a lot of fun."

"What hurt was we had a [4:21] power play to start the second period and we did nothing with it," Lightning coach Jon Cooper said. "And we weren't even really a threat, so instead of being an energy boost for us ... now you don't' have to score on it but you've got to turn the tide of the game and we didn't."
Stafford gave the Bruins a 1-0 lead with a backhand from the slot at 5:56. Pastrnak extended the lead to 2-0 at 16:06. Chara scored on a power play at 9:12 of the third to make it 3-0.

They said it
"It's a game-changer. If they get momentum there then all of a sudden doubt creeps into your head for a number of different reasons. So we'll just keep it to the simple fact that we've been good on the kill all year, it's come through us in crucial times, and tonight there was no bigger time for us. And I thought we did a real good job, moved people through, mixed up the pairs up front, [defensemen] got our clears, Tuukka made the saves when he had to. But the most part we kept ourselves fresh." -- Bruins coach Bruce Cassidy on killing Brad Marchand's five-minute major
"We're not out of it; obviously a tough ladder to climb, obviously need some results to go our way but we're obviously disappointed with the game tonight. But we got to turn around quickly." -- Lightning defenseman Victor Hedman
