Brandon Tanev scored a short-handed goal with 1:03 left in overtime Wednesday to give the host Pittsburgh Penguins a 3-2 win and hand the Colorado Avalanche their first loss of the season.
Tanev's shot from the bottom of the left circle was inadvertently knocked across the goal line by Colorado's Gabriel Landeskog near the far post.
Sidney Crosby had a goal and an assist, Jake Guentzel scored and Matt Murray made 26 saves for Pittsburgh, which won its fourth straight.
Matt Calvert and Nathan MacKinnon scored for the Avalanche, who entered the game 5-0-0, the last remaining NHL team without a loss. Philipp Grubauer made 30 saves for Colorado.
Sharks 5, Hurricanes 2
Evander Kane scored a hat trick in the first period, and Martin Jones made it stand up with 36 saves as host San Jose picked up its third consecutive win with a victory over Carolina.
Kane became the first San Jose player to complete a hat trick in an opening period. He also became the ninth Sharks player to score three-plus goals in a single period, the first since Patrick Marleau had four goals in the third period at Colorado on Jan. 23, 2017.
His only other hat trick was a four-goal game for the Sharks at Calgary on March 16, 2018. Kane also had an assist Wednesday. Barclay Goodrow and Tomas Hertl also scored goals, and Brent Burns and Hertl each had two assists for San Jose.
Oilers 6, Flyers 3
Connor McDavid scored once in a five-point game, and Leon Draisaitl scored twice and added an assist as host Edmonton made quick work of Philadelphia with their sixth win in seven games this season.
McDavid has 17 points through seven games this season, a feat equaled by in franchise history only by Wayne Gretzky.
Mikko Koskinen stopped 49 shots for the Oilers, who have won six of their seven contests. Ryan Nugent-Hopkins had a goal and an assist for Edmonton, which also got goals from Ethan Bear and Brandon Manning.
Ducks 5, Sabres 2
Rickard Rakell, Ryan Getzlaf and Adam Henrique scored second-period goals as host Anaheim rallied to hand Buffalo its first regulation defeat of the season.
The Ducks, returning from a 2-2-0 road trip, won at home for the third time in three tries. The Sabres had their three-game winning streak snapped.
Victor Olofsson scored his sixth goal of the season on the man advantage in the second period for Buffalo, extending his own record by becoming the first player in NHL history to score the first eight goals of his career all on the power play.
Capitals 4, Maple Leafs 3
John Carlson finished with one goal and two assists and host Washington used a three-goal burst over 78 seconds in the second period to top Toronto and pick up its first home win in four tries this season.
Carlson now has three goals and 11 assists to rank among the NHL scoring leaders. The defenseman assisted on Washington's first two goals and scored the fourth one, while Nicklas Backstrom added a goal and an assist, and Jakub Vrana and Evgeny Kuznetsov also scored for the Capitals.
Toronto got first-period goals from Kasperi Kapanen and Ilya Mikheyev, seemingly taking charge with a 2-0 lead. But rookie Ilya Samsonov, starting in goal for Washington, recovered to make 29 saves. Michael Hutchinson made 28 saves for Toronto.
Blue Jackets 3, Stars 2
Zach Werenski and Alexander Wennberg each had first-period goals, and host Columbus added to Dallas' early-season misery.
Sonny Milano added a highlight-reel, third-period goal, and Joonas Korpisalo stopped 30 shots as the Blue Jackets posted back-to-back wins for the first time on the young season. Columbus also extended its winning streak over Dallas to eight games.
The Stars fell to 1-6-1 and continue to struggle on offense. Miro Heiskanen scored near the end of the first period, and Joe Pavelski finally got his first goal with Dallas, which has totaled just 15 goals and is a paltry 1-for-24 on the power play.
