BOSTON -- The Boston Bruins extended their lead for the second wild card into the Stanley Cup Playoffs from the Eastern Conference with a 4-1 win against the Nashville Predators at TD Garden on Tuesday.
The Bruins (40-30-6) are three points ahead of the Tampa Bay Lightning and four ahead of the New York Islanders and Carolina Hurricanes in the wild-card race. Boston has six games remaining, and Tampa Bay, New York and Carolina each has seven.
Noel Acciari scored his first NHL goal, and Patrice Bergeron, David Krejci and David Backes also scored for the Bruins, who are one point behind the Toronto Maple Leafs for third in the Atlantic Division. Toronto, which has one game in hand on Boston, defeated the Florida Panthers 3-2 on Tuesday.

Tuukka Rask made 24 saves in his return to the Bruins net after he missed a 2-1 win at the New York Islanders on Saturday because of a lower-body injury. He was 0-4-0 with 15 goals-against in his previous four games.
"We needed it," Rask said. "Personally, I've lost four games, but I played a couple good games there and we just didn't get the bounces. But we kind of got on the winning habit there on Long Island, and me stepping in there I just wanted to make sure that I gave us a chance to win, and the guys did the rest. It was a great team effort, I think, because we blocked  shots, which is huge."
Pekka Rinne made 27 saves, and Craig Smith scored for the Predators, who had won four in a row.
"To be honest with you, I feel like we can elevate our game and be better than that," said Rinne, whose season-high five-game winning streak ended. "It was a playoff atmosphere, but I think playing-wise I think we can do a better job and I know we will."

They said it
"You know, we made mistakes early on and gave them the lead. From there, we're chasing the game. I thought we got better as [the game] went on, but I thought they jumped us in the first." -- Predators coach Peter Laviolette
"It feels pretty good. Couldn't have done it without a good D zone and Riley Nash with an unbelievable pass, so he left me with the easy part there." -- Bruins forward Noel Acciari on scoring his first NHL goal
"He really worked hard to find pucks in traffic. They created some good opportunities, and even the goal against, he found it. They just tipped it at eye level, so it was going to be a tough one, and we need to be better in the shooting lane on that one. But I thought he was terrific, very pleased with his performance." -- Bruins coach Bruce Cassidy on goaltender Tuukka Rask
