They played hockey on Saturday night at 33rd Street and 7th Avenue in the big city. For the Rangers, it was a good thing.

New additions Jack Roslovic and Alex Wennberg fit in well in a 4-0 home win over the Blues at Madison Square Garden.

Roslovic showed off his speed while playing up on the top line with Mika Zibanejad and Chris Kreider. Wennberg played responsibly, even getting a shorthanded breakaway that drew a penalty. He would later record his first point as a Ranger by assisting on a Kaapo Kakko tally in the third period.

Without captain Jacob Trouba, who’s expected to be sidelined from two to three weeks, Zac Jones stepped into the lineup and did a good job. The extra defenseman proved again that he could come back in and be dependable. In 17:17 of ice time, he paired up with Erik Gustafsson and finished a plus-one.

Jones was called upon by Rangers coach Peter Laviolette to play a key role on the blue line. So. They went with four lefty defensemen and two right defensemen. Chad Ruhwedel sat out. He’s just insurance.

The Blues were no match for the Blueshirts. They got first period goals from Vincent Trocheck (power-play) and Jimmy Vesey (even strength) to roll to a 2-0 lead.

Trocheck’s came in his 700th career game. He continues to pile up the points. He has 13 points (8-5-13) over the last 10 games. It’s been his consistency that’s overshadowed an off year for Zibanejad. He’s gone six consecutive games without a point. With 19 games left on the schedule, he needs to find his game.

Even without Zibanejad doing much, sidekick Chris Kreider added his 32nd goal of the season on the power play in the third period. It was career goal number 297. Kreider continues to produce despite Zibanejad’s struggles. He needs eight goals to reach 40 for the second time in three years.

Looking more comfortable playing on the third line, Kakko had a strong game. Wennberg fit in seamlessly with Will Cuylle and Kakko. They were effective OK the cycle at five-on-five.

Even better, Kakko converted an Erik Gustafsson rebound on the power play for his eighth goal to put the contest out of reach. It came on the second unit, which included Wennberg. He helped set it up. Perhaps adding the center can make the second unit better. He was part of it with Kakko, Alexis Lafreniere, Gustafsson, and Roslovic. Roslovic hit the goalpost off a faceoff win.

Igor Shesterkin continued his turnaround. He stopped 14 shots in a busy first period en route to a 26-save shutout. It was his second of the season. Things are looking up for the Rangers. Now that Shesterkin is back in form, they have to feel good about their chances.

If there was a player who was a factor in last night’s win, it was Matt Rempe. The 21-year-old rookie continued to impress in his ninth NHL game.

Playing on the fourth line with Vesey and Barclay Goodrow, the tower of power was effective again during shifts. He got in on the forecheck and used his size to screen Blues goalie Jordan Binnington.

The lovable gentle giant even almost had a goal in the second period. Replays on MSG Network were inconclusive. If the puck didn’t completely the goal line, it was about as close it gets.

Rempe’s reaction by the Rangers bench was how everyone felt watching the replay. The enthusiasm he brings is one of his best attributes. He is always smiling.

When the crowd chants his name, he loves it. Whether it’s before the game or during it, Rempe is the people’s champ. A fan favorite whose jersey will be selling like hotcakes. Number 73 is number 1 in Garden hearts. Only Shesterkin gets this kind of love. He’s supposed to.

The play of the checking line was so good that Laviolette rewarded them with extra shifts. Rempe played over 11 minutes. That included a 37-second shift on a late power play with time winding down. His teammates tried to feed him in front.

How much do they appreciate him? Ask ace defenseman Adam Fox.

“I think people have been talking about Linsanity and stuff like that, but I think he’s playing good hockey too. He’s not some sideshow. He plays his game hard, gets in on the forecheck and if you’re on the other side – you feel his presence,” Fox told reporters after picking up a pair of assists on power-play goals.

“I’m sure it’s not fun taking hits from him. He’s able to step up when he has to. He fought early. I don’t know if he needs to do that every game, we’re starting to see that.

He’s playing good hockey and I think that’s the biggest thing. The crowd appreciates how much he loves it too – he has a smile mid shift when he’s getting chances at the other end there. He’s a great kid and he’s come in and worked hard.”

It’s impossible not to admire the way Rempe approaches each shift. He puts in an honest effort like most gritty New Yorkers. That is something they identify with. It’s why the chant is “Rem-pe, Rem-pe!!”

If Laviolette likes what he brings, then we’ll continue to see Rempe in the lineup. However, Jonny Brodzinski has been a reliable player. He also deserves to get back in. That’ll depend on what the coach decides game to game.

He also had to be pleased with the play of Braden Schneider. He moved up to the second pair to play with K’Andre Miller. Without Trouba, Schneider should continue to take on a bigger role on the back end. When they have been paired up, Miller and Schneider work well together. It’s a tandem that could be the future of the club.

The Rangers are back in action Monday night when they host the Devils. They’ll play a back-to-back on Tuesday against the second place Hurricanes, who are hot on the trail. It’ll be a busy week with stops at Tampa this Thursday and Pittsburgh next Saturday.

It’s five games in seven days with a visit to Elmont to face the Islanders on Saint Patty’s Day.

With a schedule that includes Winnipeg, Boston, Florida, and Colorado, March doesn’t let up.
