Observations: Bruins 4, Islanders 1

The Boston Bruins concluded a five-game road trip with a 4-1 win over the New York Islanders on Tuesday night at Nassau Veterans Memorial Coliseum. The Bruins have won four straight since losing at Buffalo on Feb. 15.

BruinsIslandersBoston received its goals from Adam McQuaid, Brad Marchand, David Krejci and Gregory Campbell (empty net) en route to victory. Bruins goaltender Tuukka Rask made a season-high 36 saves in a solid performance between the pipes.

The Bruins gained a 1-0 lead at 6:43 of the first period when McQuaid scored his first goal of the season. His slap shot from the top of the right faceoff circle snuck by Islanders goaltender Evgeni Nabokov.

New York knotted the game at 1-1 when Casey Cizikas scored at 15:49 of the first period after the Islanders capitalized on Boston's defensive breakdown.

It didn't take long for the Bruins to regain the lead as Marchand scored 38 seconds into the second period for a 2-1 advantage. He has 10 goals on only 29 shots this season, and he now has 13 points in 15 games.

Boston's top line gave the Bruins a 3-1 lead at 5:16 of the second period. Krejci finished off a terrific puck-moving attack, which began on a heads-up breakout pass by defenseman Zdeno Chara. Milan Lucic and Nathan Horton assisted on the goal.

Campbell added the Bruins' fourth goal, an empty-net tally, at 18:55 of the third period.

SAVES OF THE GAME: With Boston holding a 1-0 lead early in the first period, the Islanders' Michael Grabner created a breakaway at 8:07, but Rask made a huge right-pad save to stifle New York's scoring opportunity. The Bruins had a 3-1 lead in the second period when Grabner had a short-handed breakaway at 7:04, but again Rask came up with the save. He was outstanding the entire game, but those two saves were pivotal for the Bruins.

MILESTONE: Tyler Seguin increased his point streak to five games when he assisted on McQuaid's goal in the first period. Seguin, who has one goal and five assists in the last five games, produced a solid forecheck, gained control of the puck and fed the defenseman for the goal. The assist was Seguin's 100th career NHL point.

SPECIAL TEAMS: The Bruins entered Tuesday's game having killed off 21 consecutive penalties and they continued that streak against the Islanders. Boston went 3-for-3 on the PK. The Bruins went 0-for-4 on the power play.

LIFE OF PI: Forward Daniel Paille played his 200th career game with the Bruins Tuesday night. Boston acquired him from the Buffalo Sabres in exchange for a pair of draft picks on Oct. 20, 2009. Paille has been a key member of the Bruins, a mainstay on the team's energy line, and one of the best penalty killers, too. The 28-year-old veteran has played a total of 395 games in the NHL for the Sabres and the Bruins. This season, he has three goals and three assists for six points in 14 games.

NO RYDER: If Bruins fans were hoping for a triumphant return of forward Michael Ryder, that's not going to happen. A member of the 2011 Stanley Cup team in Boston, Ryder was traded Tuesday from the Dallas Stars to the Montreal Canadiens in exchange for forward Erik Cole and a 2013 third-round draft pick.

UP NEXT: After concluding their five-game road trip with Tuesday's victory over the Islanders, the Bruins return home and will host the Senators on Thursday (7 p.m.), the Tampa Bay Lightning (1 p.m.) on Saturday and the Montreal Canadiens (7:30 p.m.) on Sunday.
