CHICAGO — Brent Seabrook and Jonathan Toews each scored a goal and added an assist to help lead the Chicago Blackhawks over the Los Angeles Kings 3-2 Sunday, extending their season-opening points streak to 15 games. Patrick Sharp also scored for the Blackhawks (12-0-3), who matched the 1984-85 Edmonton Oilers for the second-longest season-opening points streak in NHL history. Chicago is one away from the league record, set by Anaheim in 2006-07, and will try to match the mark Tuesday against Vancouver. Mike Richards scored two power-play goals in the third period to pull the Kings within one after Chicago had built a 3-0 lead. Blackhawks backup goalie Ray Emery made 25 saves. He lost a bid for his first shutout in more than three years when Richards connected 56 seconds into the third period. Sharp, who led Chicago with 33 goals last season, ended a 10-game drought without a score. Penguins 4, Sabres 3: Defenseman Paul Martin scored with 2:04 left and Pascal Dupuis had two goals and an assist to lift Pittsburgh to a victory over Buffalo. Sidney Crosby also scored and had two assists, including a pass that set up Martin's goal. Pittsburgh (11-5-0) won its third straight and improved to 8-2 in its past 10 games to move ahead of idle New Jersey atop the Eastern Conference standings. The Penguins were forced to rally after squandering a 2-0 lead. Dupuis tied it at 3 with 5:17 left before Martin got his second of the season off a deflection in front of the net. Thomas Vanek had a goal and an assist, and Steve Ott and Cody Hodgson also scored for Buffalo. Blues 4, Canucks 3, SO: T.J. Oshie and Andy McDonald each scored in regulation and in the shootout to lead St. Louis over Vancouver. Patrik Berglund also scored for the Blues, who closed a 3-0 road swing after a five-game skid. Blues rookie goaltender Jake Allen made 28 saves and stopped the Canucks' Ryan Kesler and Alex Burrows in the shootout. Kesler and Henrik Sedin had their first goals of the season, and Mason Raymond also scored in regulation for Vancouver, which has lost two straight after winning six in a row. The Blues led 3-2 lead early in the third before Raymond tied it on a power play with 1:47 left. Rangers 2, Capitals 1: Derek Stepan's power-play goal early in the third period snapped a tie and completed New York's rally past Washington. Washington, which lost to New York in the second round of last year's playoffs, had been 11-5-2 in its last 18 regular-season games against the Rangers. New York is 5-1-1 in its past seven games. Carl Hagelin tied it for the Rangers in the second period after defenseman John Carlson put Washington ahead in the first. Henrik Lundqvist stopped 27 shots for his seventh win. Braden Holtby was busier for Washington and made 38 saves. Wild 3, Red Wings 2: Dany Heatley, Jason Zucker and Torrey Mitchell all scored in the second period to rally Minnesota over Detroit. It was Minnesota's first regulation win since Jan. 29 and just the second time it scored at least three goals in regulation over the last nine games. Damien Brunner and Pavel Datsyuk scored for Detroit, which has lost three straight for the first time since March 10-21 of last season. After Heatley snapped a nine-game scoring drought to make it 2-1, Zucker went coast-to-coast and scored his first NHL goal to tie it. Mitchell scored off a faceoff 30 seconds later. Bruins 3, Jets 2: Brad Marchand scored 36 seconds into the third period to lift Boston to a win over Winnipeg. Tyler Seguin and Daniel Paille also scored, and Patrice Bergeron had two assists for the Bruins (9-2-2). Tuukka Rask stopped 22 for Boston to earn his seventh win of the season. Alexandre Burmistrov had a goal and an assist for Winnipeg (5-8-1), while Evander Kane recorded his fourth goal of the season and first in nine games. Ondrej Pavelec made 23 saves for the Jets, who lost their third straight and fourth in a row at home — the longest home losing streak for the team moved from Atlanta prior to last season. Flames 4, Stars 3: Steve Begin, Matt Stajan and Roman Horak each scored their first goals of the season in the third period and Calgary overcame a two-goal deficit to beat Dallas. Begin snapped a 3-3 tie with 9:30 remaining. After Chris Butler's slap shot from the left point was blocked in front, Begin outbattled two Stars defenders to get to the loose puck and fire a wrister that beat goaltender Richard Bachman. Michael Cammalleri also scored for Calgary and Joey MacDonald made 27 saves. Antoine Roussel, Reilly Smith and Ryan Garbutt scored second-period goals for Dallas, while Bachman stopped 22 shots four days after he gave up six goals on 22 shots in Calgary. — Agencies
