For the Rangers, Monday’s six-hour flight to Vancouver should be a pleasant one.

The Blueshirts, coming off a 1-4-1 skid, rode a two-goal night from center Derick Brassard and toppled the Ottawa Senators, 4-1, Sunday night at Madison Square Garden.

With the Rangers leading 2-1 in the third period, Brassard raced ahead of the field to collect a bouncing pass, fired from the top of the left circle and beat goalie Craig Anderson at 10:08.

It certainly qualified as a breakout evening for Brassard, who had only one goal in the previous nine games.

“I just tried to go short side,’’ he said of his second goal of the game. “We knew the next goal was really important, We were just trying to push a little harder to get it.”

Jesper Fast added an empty-netter with 1:31 left.

Defenseman Ryan McDonagh also had a big night offensively with a goal and two assists, which tied a career high.

Said McDonagh, “We’re coming along with our puck management and our decision-making. Tonight was pretty close to a good 60 minutes, not turning pucks over, not giving them a lot of looks. It was great to see us come off of a couple days’ rest. We needed it, and came out rejuvenated and with speed.”

The Rangers (18-7-3) tightened their defense in the third, allowing Ottawa only three shots on Henrik Lundqvist in the final 20 minutes.

The Rangers are 12-4-1 at home but play the next three on the road in Western Canada. It also was a rare win here over the Senators, who came in 8-0-1 in their last nine games at the Garden.

Said Marc Staal: “We [the defensemen] weren’t forcing anything. When we get the pucks to the forwards, it makes their job easier. Definitely going into this road trip is a big three-game swing, so we’re excited to keep on improving.”

With the Rangers having scored only six goals in the previous four games, coach Alain Vigneault juggled his lines. The Rangers took a 2-0 lead in the first period, not five-on-five but on power-play goals.

Said Brassard, “We had a good first period, and the power play was the main reason. We tried to move the puck around. When the guys had shots, they’d take them, and we had some good screens in front.”

With Chris Kreider screening Anderson, McDonagh fired a high one-timer from the left point that opened the scoring at 8:40. The captain’s fourth goal of the season was the first by a Rangers defenseman in 10 games.

When the Senators’ bench drew an unsportsmanlike-conduct penalty, apparently for repeated chirping to an official, McDonagh’s wrister from near the same spot was deflected by Brassard, also above Anderson’s glove, at 13:47.

It was only the second game all season in which the Rangers had more than one power-play goal. They had two against Carolina on Nov. 30 during a stretch of nine games in 15 days in which they slumped, posting a 3-5-1 mark.

Lundqvist, who finished with 23 saves for his 14th win, had to be sharp, and a little fortunate, early in the second. He made an acrobatic stop on Bobby Ryan, whose rebound hit the side of the net. Ryan then was held and dumped by J.T. Miller, but the Rangers fended off the man-advantage.

Marc Methot’s shot, which deflected off Staal’s stick and past Lundqvist at 6:01 of the second, brought the visitors within one.

The Blueshirts had to thwart another power play stemming from a thoughtless interference penalty from Kreider on Alex Chiasson in neutral zone with 5:24 left.

With 57 seconds left in the second, Dylan McIlrath, who received more ice time than usual, blocked a shot and was prone with the puck under him, but David Dziurzynski scooped it out and whipped a shot that Lundqvist lunged at and snared with his glove.

In the third, Anderson, starting his 11th straight game, stopped two great opportunities by Oscar Lindberg and Kevin Hayes around the five-minute mark.
