BOSTON — The Boston Bruins defeated the Arizona Coyotes 4-1 on Saturday night at TD Garden in the Original Six club’s final game before Monday’s NHL trade deadline.

The Bruins have a four-day break before returning to game action Thursday night against the Calgary Flames at TD Garden.

Here are three takeaways from Bruins-Coyotes:

1. Bruins Open Scoring In Excellent First Period Performance
The Bruins scored first for the fourth straight game after Coyotes goaltender Mike Smith mishandled the puck behind the net and allowed Milan Lucic to score his 13th goal of the season.

Boston doubled its lead when Brad Marchand scored his team-leading 18th goal of the campaign.

The Bruins finished the first period with a 20-12 advantage in shot attempts, a 13-9 edge in shots on goal and a 13-9 lead in scoring chances.

Here’s a first-period recap from the NESN broadcast.

2. Patrice Bergeron Line Dominates
Boston’s top line of Patrice Bergeron, Marchand and Reilly Smith dominated the game, and the Coyotes had no answer for them in all three zones.

Marchand and Bergeron each scored and earned an assist, while Smith tallied two assists. This trio also combined for 10 shots on goal and helped Boston control more than 60 percent of even-strength shot attempts when it was on the ice. Bergeron also won 60 percent of his faceoffs.

Many of the scoring chances this line created were the result of good work in the defensive zone followed by speed through the neutral zone.

3. Tuukka Rask Earns Win No. 25
Rask made his 52nd appearance of the season after missing Friday night’s game with an illness. He made 31 saves on 32 shots for a .933 save percentage. Veteran winger Martin Erat scored Arizona’s only goal on a beautiful tip in the low slot at 10:21 of the third period.

Rask, who owns a .932 adjusted save percentage since Jan. 8, has given up two goals or fewer in 11 of his last 15 starts (including three straight).
