BOSTON – The Sabres have looked good on the road. The Bruins have looked bad at home.
It was time for a role reversal.
Boston gave the TD Garden crowd plenty of reasons to get loud Monday night, scoring three power-play goals to easily dispatch Buffalo, 4-0. The Sabres dropped to 4-2-2 on the road, while Boston improved to 2-3 in front of their fans.
The Bruins scored three times during the second period to put the game away. They improved to 120-1-2 when taking a three-goal lead since the start of the 2011-12 season.
Boston entered the game ranked 29th on the power play at 7.9 percent, but it became the second team this season to beat Buffalo with three power-play goals. Philadelphia also did it.
Tuukka Rask had a 32-save shutout.
Power Play I: The Bruins opened the scoring with the man-advantage with 5:44 gone in the second period. David Pastrnak stopped Zemgus Girgensons from clearing the puck, and Brad Marchand played pinball to continue his torment of the Sabres. Marchand’s shot hit Robin Lehner’s mask, bounced off the goalie’s stick and caromed into the net.
Marchand has 16 goals in 32 games against Buffalo.
Power Play II: The Bruins were set to have a five-on-three for 2:34 after double-minors to Girgensons (high-sticking) and Jake McCabe (tripping, unsportsmanlike conduct). Boston needed less than one minute to make it 2-0. David Krejci teed up a blast from the left circle with 9:48 to go in the second.
When it rains …: The Sabres’ luck continued to flow downhill with 5:19 left in the second. Boston’s Riley Nash sent a pass to the front of the net, where it hit the skate of Dmitry Kulikov and slipped past Lehner. The Sabres defenseman smashed his stick on the glass in disgust.
Power Play III: The Bruins added another celebration with 10:15 remaining. Pastrnak got the rebound of a power-play point shot and easily deposited it for his eighth goal and a 4-0 lead.
One-sided period: With major help from their five power plays, the Bruins outshot the Sabres, 15-5, during the second period.
Unfamiliar trips: Ryan O’Reilly took only four penalties in 71 games last year and had just one in 80 games for Colorado in 2013-14. He went to the box twice in Boston, tying his career high. He hadn’t been so penalized in one game since Jan. 2, 2012. He left the ice for tripping with 11:29 gone and had a high-sticking call 4:03 into the second period.
Toothpick alert: For at least the third time this season, Sabres defenseman Rasmus Ristolainen wound up for a power-play slap shot only to have his stick snap in half. He fanned on another point shot during the second period.
Swing and a miss: David Backes had Kulikov in his sights. Instead, he said hello to his Bruins teammates. Backes zoomed toward the boards to hit Kulikov late in the first, but the Sabres defenseman stopped and Backes went headfirst into his bench.
Drop 'em: Derek Grant's first NHL fight was a short one. He pushed Marchand into the net, then answered Matt Beleskey's call for revenge. Grant, who had six fights in the minors, ducked two Beleskey blows and landed one while falling to the ice in the third.
Bad start: Former Sabres center Dominic Moore had the first scoring chance of the game, getting alone at the top of the crease. With time to shoot, he fired high over the net. Three minutes later, he took the first penalty of the game.
He shoots, he doesn’t score: The Sabres (13) and Bruins (12) combined for 25 shots in a back-and-forth first period, but they ended it scoreless. In 12 games this season, the Sabres have scored seven times in the first period and given up seven.
Zero to 100: Sabres right wing Sam Reinhart played in the 100th game of his career. Reinhart recorded 25 goals, 24 assists and 49 points in his first 99 appearances.
Counting the house: The Bruins announced their 299th straight sellout of 17,565. The building was only about 75 percent full, but it sounded like 100 percent.
Next: The Sabres flew home following the game and are scheduled to take Tuesday off. They’ll return to the ice Wednesday when they host the Ottawa Senators at 7:30 p.m. in KeyBank Center. It will be the second of three meetings this month. Buffalo won in Ottawa on Saturday and returns to Canada’s capital Nov. 29.
