It was another frustrating night for the Canucks, who are all but assured of missing the playoffs for the first time in six seasons.
Coming off a demoralizing 5-1 loss to the Anaheim Ducks on Saturday, the Vancouver players showed the fight they have been preaching in the locker room but were unable to translate that effort into a result on the scoreboard.
"I thought we should have won this game, but it doesn't matter right now," Canucks forward Daniel Sedin said. "We are where we are because we've been on the wrong side of these kind of games throughout the season."
The game marked the regular-season return of Rangers coach Alain Vigneault to Rogers Arena. Vigneault coached in Vancouver for seven seasons, winning six division titles and leading the Canucks to within a victory of the 2011 Stanley Cup.
The Canucks fired Vigneault last summer after the club's first-round playoff exit and replaced him with John Tortorella after the latter was axed by the Rangers. The flip flop of coaches has worked out much better for New York, with Vancouver limping toward an uncertain offseason.
The Rangers led 2-1 after two periods, and St. Louis, who was acquired at the trade deadline from the Lightning, put the game out of reach while killing a penalty at 10:15 of the third.
Vancouver defenseman Yannick Weber dove trying to keep the puck in at New York's blue line but failed to do so, allowing Rick Nash and St. Louis to race the other way on a 2-on-1. Nash fed a perfect pass to St. Louis, who ripped his 30th of the season.
"There is a lot of things playing against you a little bit with a new team and new environment, but you try to stay the course, play the right way, and find that fine line of anticipating and not cheating," St. Louis said. "I feel like I am getting more comfortable finding that line."
Vigneault said the commitment to defense shown by star players such as St. Louis and Nash allows him to put them on a penalty kill that has 10 short-handed goals this season and three in the past two games.
"Those guys are willing to do what it takes to kill penalties, which is get in lanes and block shots and have good sticks, and it's paid off," Vigneault said.
The Canucks trailed 2-0 after the first period but showed fight in the second for the embattled Tortorella, with Kesler cutting the Rangers' lead in half at 6:21.
"I thought it was a good hockey game. I thought we played better through the game than the other night (against Anaheim)," Tortorella said. "I thought our team played hard. We don't score. They score three, we score one."
The Rangers grabbed a 1-0 lead at 4:59 of the first when Carcillo banged home his fourth of the season on a play that had the Canucks fuming. Lack appeared to have the puck covered, but Rangers forward Brian Boyle jarred it loose moments before the goal.
"I felt like I had it under my glove and then I get a pitchfork and I lost it and they scored," Lack said. "(The ref) said that he was going to look at it after."
New York stretched the lead to 2-0 at 14:43 on the power play. Lack made a great blocker save on Rangers forward Mats Zuccarello, but the puck bounced to Derick Brassard, who in turn fed a wide-open Pouliot for his 13th.
"No whining. We lost. We're losing," Tortorella said. "We've just got to keep on trying to get better."
Burrows was assessed a five-minute penalty for elbowing on Rangers defenseman Ryan McDonagh late in the third period. McDonagh appeared to be in some discomfort as he left the ice. Vigneault did not provide an update after the game. ... New York set a franchise record with its 25th road victory of the season.
