OTTAWA: Erik Karlsson's two goals and an assist led the Ottawa Senators to a 3-1 win over Pittsburgh Sunday night, despite Penguins star Sidney Crosby extending his points streak to 24 games. Jason Spezza also scored three points for Ottawa, but left in the second with an upper-body injury. Crosby's 30th goal spoiled Brian Elliott's shutout bid. But Crosby, the NHL's leading scorer with 61 points, also conceded a couple of costly penalties. Mike Fisher scored the first of Ottawa's two power-play goals midway through the first after Crosby was sent off for hooking. Karlsson made it 2-0 at 13:42 during a delayed slashing call against Crosby, who also hooked Chris Phillips late in the second to negate a Penguins power play. Elliott turned aside 44 shots, including 22 in the second period, as Ottawa won consecutive games for the first time since a season-high four-game winning streak in early November. Marc-Andre Fleury made 21 saves for Pittsburgh, which had won 16 of 18, including three in a row. Capitals 3, Hurricanes 2: In Raleigh, North Carolina, Alex Ovechkin ended an eight-game drought without a goal and added an assist for Washington, which held on for the win. Mathieu Perreault and David Steckel also scored for the Capitals. They have won three of four and swept the Hurricanes on their home ice for the first time since the 1997-98 season. Tuomo Ruutu and Jussi Jokinen each had a goal and an assist, and Cam Ward made 27 saves for the Hurricanes. Carolina has lost three straight in regulation for the first time this season. Blackhawks 4, Blue Jackets 1: In Chicago, Patrick Sharp scored two goals and Marty Turco made 26 saves to lead the Blackhawks to their fourth straight win. Turco lost a bid for his second shutout this season when Derick Brassard scored on a screened power-play goal with 2:26 left in the third period. Tomas Kopecky and Dave Bolland also scored for Chicago, which has allowed just five goals during its winning streak. Lightning 3, Thrashers 2, OT: In Atlanta, Vincent Lecavalier's second goal of the game – a power-play 1:13 into overtime – gave Tampa Bay victory. Red Wings 4, Wild 1: In St. Paul, Minnesota, Henrik Zetterberg scored a goal and an assist to power the Red Wings to victory. Coyotes 1, Stars 0: In Dallas, Jason LaBarbera stopped 29 shots for his fifth career shutout and Kyle Turris scored in the second period, leading Phoenix to the win.
