Alain Vigneault is trying to improve his chances at ending the slump.
Vigneault is expected to shuffle the lines as St. Louis and the Rangers go for a bounce-back performance Sunday night against the last-place Edmonton Oilers.
New York (41-30-4) acquired St. Louis from Tampa Bay earlier this month, adding what it hoped was another bona fide offensive threat to make a deep run in the playoffs.
Instead, the Rangers are dealing with a struggling All-Star, who led the NHL with 60 points in 48 games last season. St. Louis, who was leading the Lightning with 29 goals and 61 points, has just three assists in 13 games since moving to New York.
He's been held without a point in five straight games, while mustering just four shots. He had only one attempt on goal Friday, when the Rangers fell 4-3 at Calgary to snap their five-game winning streak in the opener of this four-game Western Conference road trip.
"It's a little bit of unchartered territory, meaning I haven't experienced that kind of adversity. I haven't gone through something like this before really," St. Louis told the team's official website. "It's easier said than done to get out of this."
Vigneault is hoping he's found a solution. He's expected to move St. Louis back to a line with former teammate and center Brad Richards and left wing Carl Hagelin. The shift would put St. Louis back at his natural right wing position after playing on the left with Rick Nash and Derek Stepan.
"I know Hags and Richie have gotten some good chemistry, so by putting Marty back in there - and I know we've tried that before - we still keep that duo and continuity on the line," Vigneault told the team's official website. "I'm hoping that's going to work.
"Marty expects more from himself, obviously, as far as point production. He's working extremely hard, and when players work as hard as he does they usually find their way; and I am confident he will."
A visit to Edmonton may not help since St. Louis hasn't scored in eight career games at Rexall Place, and he's pointless in the past three overall versus the Oilers (26-39-9).
The Rangers haven't fared well against them either, losing 2-1 at home Feb. 6, and dropping their last visit to Edmonton 2-0 on Oct. 22, 2011.
Derick Brassard had the goal in the most recent meeting with the Oilers. The center has failed to generate a point over the last two games after totaling four goals and one assist during the previous four contests.
Edmonton, which occupies the Western Conference basement, is trying to conclude a six-game homestand at .500.
The Oilers ended a three-game slide by beating Anaheim 4-3 on Friday behind Ben Scrivens' 48 saves and David Perron's career high-tying three assists.
"That's what we have a good goalie for, so it's nice to see him come up big," captain Andrew Ference said. "We're not going to get picky about having some positive feelings in here."
Scrivens will likely be back in net, and he's won both of his career meetings with the Rangers, stopping 72 of 73 shots. He made 35 saves for the Oilers on Feb. 6.
Oscar Klefbom is looking to build on his first career goal after coming up empty in his first eight games. The 20-year-old defenseman was the 19th overall selection in the 2011 draft.
