ST. LOUIS (AP) Jaden Schwartz and Alex Pietrangelo scored second-period power-play goals and Jake Allen made 23 saves to help the St. Louis Blues beat the Calgary Flames 5-2 on Wednesday night.

St. Louis has won three of its last four, losing only to red-hot Las Vegas in overtime.

Calgary had won its first four road games this season. Mikael Backlund scored twice for the Flames.

Schwartz and Pietrangelo scored in a span of 2:46 to break a 1-1 tie. The Blues had come up empty on their previous 18 power-play chances.

LAS VEGAS (AP) Oscar Dansk stopped 29 shots for his second career win in two appearances, and the Vegas Golden Knights beat the Chicago Blackhawks 4-2 on Tuesday night for their fourth straight victory.

Dansk made his first NHL start after replacing injured Malcolm Subban during a 3-2 win over the St. Louis Blues on Saturday. The 23-year-old gave up goals to John Hayden and Patrick Kane, but was otherwise stellar for the Golden Knights.

Vegas is the 10th expansion team to put together a four-game winning streak. The Golden Knights are 7-1-0 in their inaugural season.

This one didn't start so promising. Hayden stuffed one past Dansk just 3:33 minutes into the game for a short-handed goal.

The Golden Knights didn't take long to answer. William Karlsson tipped Colin Millers' shot from the point past Chicago's Corey Crawford.

A little over a minute later, Tomas Nosek pushed Deryk Engelland's rebound under Crawford's pads to give the Golden Knights a 2-1 lead.

Pierre-Edourard Bellemare extended the lead to 3-1 late in the second when he smacked Nosek's pass from behind the net past Crawford.

Activated from the injured reserve list hours before the game, Jonathan Marchessault took a pass from Nate Schmidt and hit the upper left corner of the goal with a shot Crawford never saw, making it 4-1 with 9:40 left in the game.

Kane finished the scoring with 1:05 left, extending his point streak to six games, the longest this season by a Blackhawks player.

Crawford stopped 29 of 33 shots on goal.

NOTES: Nationals star and Las Vegas High School grad Bryce Harper was at the game. ... The Golden Knights came into the game allowing 2.43 goals per game, fourth-best in the league, with the Blackhawks right behind them at 2.44. ... Vegas reassigned Vadim Shipachyov to the AHL's Chicago Wolves to make room for Marchessault, who has enjoyed success against Chicago, recording a hat trick last season, in March. He has two 3-point games against the Blackhawks in his career. ... Though he didn't register a point Tuesday, Golden Knights left wing James Neal has 20 points (14 goals, six assists) in 28 games against Chicago. The Blackhawks are one of four teams Neal has recorded at least 20 career points against. ... Chicago came into the game having killed 22 of 25 penalites over its previous six games. It killed four of five against Vegas. ... Duncan Keith leads the Hawks with seven assists but has yet to score a goal.

PITTSBURGH -- A game between the Pittsburgh Penguins and Edmonton Oilers can be circled on the calendar well in advance for the matchup between stars Sidney Crosby and Connor McDavid.

Perhaps it will play out that the centers who are widely considered the top two players in the world -- Crosby, 30, who has captained Pittsburgh to three Stanley Cups, including the past two; and McDavid, 20, who won the NHL scoring title and the Hart Trophy as league MVP last season -- will steal the show Tuesday night when the teams meet at PPG Paints Arena.

The teams, however, are more interested in getting on the right track.

The Penguins (5-3-1) are coming off their second blowout loss, 7-1 at Tampa Bay on Saturday. The Oilers (2-5-0) are trying to better fill out the win column.

"Obviously, there's some added interest because of the statures of the players," Pittsburgh coach Mike Sullivan said Monday. "That's always exciting for everybody involved. We understand that.

"But our focus right now is on our team and trying to get better each and every day so that we're playing the game more consistently."

Edmonton coach Todd McLellan is on the same hunt for his club.

"We've had good practices. It's transferring it over to the game (that has been a problem)," he said. "We worked hard (Monday). We got a lot done."

So while the teams have game-planned for each other, their focus is primarily turned inward.

"I don't think we can elevate our play right now based on our opponent," McLellan said. "We have to elevate our play based on our standard. Is there a bit more of a motivating factor because these guys are back-to-back champs? I'd like to think so, but that shouldn't be what's driving our team.

"I'm sure their team and their leaders and their coach weren't very happy with what happened in Tampa and they want to make amends for it. We should be the exact same way for where we're at."

Edmonton could get a boost with the potential return of center Leon Draisaitl (concussion) and winger Drake Caggiula (undisclosed injury). Both practiced but still need medical clearance to play.

For Pittsburgh, center Riley Sheahan is expected to play after being acquired from the Detroit Red Wings in a trade Saturday.

In addition, the Penguins could dress freshly recalled rookie Casey DeSmith as the backup to goaltender Matt Murray. Antti Niemi, who has struggled and gave up all seven goals Saturday, was placed on waivers Monday. He was 0-3-0 with a 7.50 goals-against average this season.

Club officials did not disclose their plans regardless of whether Niemi is claimed by another team.

Those things could all be overshadowed if Crosby, McDavid or both put on a show.

McDavid leads the Oilers with eight points. Crosby leads Pittsburgh with five goals and is tied with Evgeni Malkin for the team lead with 10 points.

"When you're watching him, you're hoping he'll do something cool, and when you're playing against him you're not hoping that," McDavid said of Crosby.

Crosby downplayed the matchup.

"There are always matchups, story lines, things like that," he said. "We sit here and we talk about them, but our job is to go out there and play. That's what I try to do."

DETROIT (AP) Sven Baertschi scored twice, and the Vancouver Canucks used a dominant second period to pull away for a 4-1 victory over the Detroit Red Wings on Sunday night.

Vancouver scored three times in the second, outshooting the Red Wings 18-6 in the period. Baertschi, Derek Dorsett and Jake Virtanen scored in the second for the Canucks, who are 3-1 so far on a five-game trip.

Detroit has lost four in a row. Anthony Mantha scored the only goal for the Red Wings, tying it at 1 late in the first.

Vancouver opened the scoring when Bo Horvat's shot was deflected and trickled right to Baertschi in front of the net. He stickhandled around goalie Jimmy Howard and backhanded the puck in.

Mantha's equalizer came on a wrist shot from the top of the left circle.

Dorsett gave Vancouver the lead back with his fifth goal in the past five games. Horvat found him in front of the net with a pass, and Dorsett's shot bounced in the air off Howard before coming down behind him and going in the goal.

Baertschi's second goal came on a wrist shot from the top of the slot, then the Canucks added another in the final minute of the period.

Detroit's Mike Green was unable to control the puck entering the Vancouver zone and ended up knocking it backward to Daniel Sedin, who went the other way on a 2-on-1. Sedin passed to Virtanen, whose initial shot was stopped before he put away the rebound.

Sedin's assist on that goal brought his career point total to 990.

NEW YORK (AP) Kevin Hayes and Jimmy Vesey each had a goal and an assist to help the New York Rangers snap a five-game skid with a 4-2 win over the Nashville Predators on Saturday.

Chris Kreider added a power-play goal and David Desharnais extended his point streak to four games as the Rangers picked up their second victory of the season.

Mattias Ekholm and Fillip Forsberg each scored for Nashville, and Juuse Saros made 11 saves for the Predators.

The Rangers, who have struggled in first periods this season by allowing 13 goals in nine games, earned a two-goal advantage at the end of the first 20 minutes.

Jesper Fast tallied his first of the season just 5:12 into the game as New York scored the first goal for only the fourth time in nine games. Predators defenseman Alexei Emelin had trouble controlling a bouncing puck and Hayes was able to race up ice for a breakaway opportunity. Fast trailed the play and cashed in on the rebound.

After killing off three penalties of their own in the first 20 minutes, the Rangers power-play unit doubled their lead at 19:34. J.T. Miller was able to slip out of the corner with control of the puck and fed a wide-open Chris Kreider in front. It was only the second time this season that the Rangers have had a multi-goal lead.

Henrik Lundqvist made 23 saves for New York and picked up career victory No. 407. He is now tied with Glenn Hall for ninth place on the NHL's all-time wins list.

Early in the middle period, the Predators were able to cut the deficit in half. Defenseman Mattias Ekholm was able to walk into the slot all alone and blasted a slap shot past Lundqvist at the 1:44 mark of the second period.

Later in the second period, Filip Forsberg scored his sixth goal of the season when he deflected a soft Roman Josi wrist shot at 15:30.

However, later in the middle period, Hayes danced around defenseman Matt Irwin, and beat Saros on the short side with a pretty backhand, forehand maneuver to help the Rangers regain a two-goal advantage. Vesey and Brady Skjei assisted on the play.

With 4:30 remaining in the second period the Predators cut the Rangers lead in half once again. Filip Forsberg deflected a soft Roman Josi wrister as he tallied his sixth of the season, Ryan Johansen and Josi assisted on the play.

Vesey added an empty-netter in the final minute to secure the victory for New York. It was Vesey's first goal of the season.

The Predators have lost four consecutive games at MSG with their last win coming December 10, 2013.

NOTES:

Lundqvist became the 20th NHL goalie to appear in 750 games and became the third to accomplish that feat with one team (Martin Brodeur, Devils and Tony Esposito, Blackhawks). ... Alternate captain Marc Staal skated in his 698th game, tying Mark Messier and Steve Vickers for 12th on the franchise's all-time games played list. ... New York scratched F Paul Carey, F Adam Cracknell and D Steven Kampfer. ... Nashville placed C Nick Bonino on injured reserve Friday with a lower-body injury. ... D Yanick Weber was activated from injured reserve Friday, and skated in his first game since suffering an upper-body injury on October 12th against the Stars. ... Predators scratched F Pontus Aberg, D Anthony Bitetto and D Samuel Girard.

OTTAWA -- Looking for their first home victory of the season, the Ottawa Senators will face a monumental task when they entertain the Toronto Maple Leafs at Canadian Tire Centre on Saturday night.

They will have to slay a dragon -- or at least what some people view as the hottest team in the NHL.

On Friday, the Maple Leafs (6-1-0) were declared 8-1 favorites to win the Stanley Cup by Bodog, an online gambling site that had them at 14-1 on Oct. 4. The Tampa Bay Lightning were next on the updated list at 9-1.

"All that stuff is fluff," Maple Leafs coach Mike Babcock told the Toronto Sun. "I have coached lots of good teams that were (No. 1) in the ranking, that won the Presidents' Trophy, that tied for the Presidents' Trophy and didn't win the Cup. It's hard to win the Cup. It's darn near impossible. Let's not worry about that, let's try to get in the playoffs. Let's do that by winning the game in Ottawa."

The Senators (3-1-3) are trying to catch the Maple Leafs and the Lightning, who they trail by three and four points, respectively, in the Atlantic Division standings.

After sweeping their three-game road trip to western Canada for the first time in franchise history, the Senators thought they'd have a chance to gain some traction with a five-game homestand. But after losing the first two, Ottawa's record at Canadian Tire Centre is 0-1-3.

The most recent loss, a 5-4 overtime setback at the hands of the New Jersey Devils on Thursday, was the second time the Senators have thrown away a two-goal, third-period lead in their own building.

Coach Guy Boucher blamed turnovers for both losses.

"We've just got to manage the puck," Boucher said Friday. "We know at the beginning of the year it's harder. Every coach is talking about that. That's normal. Having said that, if you look at last year after seven games, and you look at this year, we're ahead in every department.

"The process starts back at zero, and we have to understand that the bad habits that were engrained are still there, but they're just going away faster than last year."

Boucher said that winger Zack Smith, who suffered an upper-body injury against the Devils, will be lost for "at least" a week. He added that defenseman Mark Borowiecki, who is also dealing with an upper-body injury, is doubtful for Saturday's game.

Making his seventh start of the season in goal for the Senators will be Craig Anderson, who has a career record of 13-6-3 against the Maple Leafs.

Toronto, which has won its last three games, is expected to counter with Frederik Andersen, who is 3-1-2 against the Senators.

The Senators held a 3-1-0 record against their provincial rivals last season, back when the young Maple Leafs were followed by only modest expectations.

"Sometimes in life when things go too good, you get a little complacent," said Babcock. "That's my job to make sure that doesn't happen, to do everything I can about that. But our players have to understand that if you get ahead of yourselves, you don't win. You just have to be diligent, but solution-based and get better every day and then you have a chance to be successful."
