BOSTON -- Even without their newest defensive acquisition, the Boston Bruins were able to stifle the Washington Capitals' high-octane offense.
The Bruins outshot the Capitals 43-16 and earned their third straight win with a 3-0 victory, ending a four-game losing streak against Washington at TD Garden.
The Bruins acquired defenseman Andrej Meszaros from the Philadelphia Flyers before the NHL Trade Deadline on Wednesday. But they scratched Meszaros and went with their incumbent sextet on defense. That group allowed the fewest shots against by a Boston opponent since the Columbus Blue Jackets had 14 in the Bruins' 3-1 win Nov. 30, 2013.
Tuukka Rask earned his League-leading sixth shutout. Gregory Campbell, Loui Eriksson and Brad Marchand (into an empty net) provided the offense for the Bruins (40-17-5), who've won six of their past nine games.
The Capitals (29-25-10) are 0-2-1 in their past three games after a four-game winning streak. Their 16 shots were a season-low.
After a scoreless first period, the Bruins showed more urgency in the second; they outshot Washington 17-4 and scored twice.
Campbell opened the scoring on a tip-in from in front at 3:05. The Bruins had Rask off the ice for an extra attacker during a delayed penalty, and Campbell got a piece of Patrice Bergeron's one-timer from the top of the left circle.
Carl Soderberg's work down low resulted in the Bruins' second goal at 8:20. Kevan Miller fired a shot from the right point that Braden Holtby from stopped, but Soderberg picked up the rebound, circled the net and found Eriksson with a backhand pass.
The Bruins outshot Washington 27-8 through two periods.
The Capitals had their best chance to get on the board in the first minute of the third period. Nicklas Backstrom found Alex Ovechkin with a back-door pass and the League's leading goal-scorer actually had put puck behind Rask. But Ovechkin's shot hit the outside of the net as he pumped his fist because he thought he had scored.
Marchand hit the empty net with 1:34 remaining after the Capitals pulled Holtby, who finished with 40 saves.
Boston will play on the road against the Tampa Bay Lightning on Saturday, the same night the Capitals host the Columbus Blue Jackets.
