Panarin raced up the left wing, worked his way past Dmitry Orlov and flicked a quick wrist shot past goalie Philipp Grubauer just under the crossbar for the game-winning goal. Ian Cole and Pierre-Luc Dubois got assists on the winning play.
Panarin finished with one goal and two assists, and Thomas Vanek added one goal and one assist.
For Washington, Evgeny Kuznetsov scored power-play goals just 29 seconds apart late in the first period, and John Carlson finished with three assists while Nicklas Backstrom added two. Game 2 is set for Sunday.
Sharks 3, Ducks 0
Kane, who was skating in his first career Stanley Cup playoff game — after 574 regular-season contests over nine campaigns — broke a scoreless deadlock at the 7:07 mark of the second period at Honda Center. He scored again with 6:09 remaining in the second period on a feed from Joe Pavelski.
Kane, who collected nine goals and 14 points in 17 games with the Sharks after a trade-deadline swap with the Buffalo Sabres, is the first player in Sharks history to score twice in his NHL playoff debut.
Lightning 5, Devils 2
Ondrej Palat recorded a goal and two assists as top-seeded Tampa Bay beat visiting New Jersey in Game 1 of their Eastern Conference quarterfinal.
Palat notched his second career postseason game with three points and first since Game 3 of the Eastern Conference finals against the New York Rangers in 2015.
He scored Tampa Bay’s first goal and then recorded the primary assist on tallies by Tyler Johnson and rookie Yanni Gourde. Alex Killorn scored the fourth goal and Nikita Kucherov added an empty-netter. Andrei Vasilevskiy made 29 saves. Game 2 is Saturday afternoon in Tampa Bay.
Bruins 5, Maple Leafs 1
David Backes and David Pastrnak scored second-period goals to break a 1-all tie and spark Boston to a rout of visiting Toronto in Game 1 of their Eastern Conference quarterfinal.
Brad Marchand, Sean Kuraly and David Krejci also scored, and Tuukka Rask made 26 saves. Game 2 of the series takes place Saturday night in Boston.
Zach Hyman had the Maple Leafs’ only goal and Frederik Andersen had 35 saves. Toronto’s Nazem Kadri was sent off with a game misconduct and match penalty with 11:42 remaining in the third after slamming the head of Boston’s Tommy Wingels into the boards while he was already down on the ice. Wingels left the game and did not return.
Predators 5, Avalanche 2
Filip Forsberg scored two third-period goals as host Nashville dumped Colorado to take a 1-0 lead in their best-of-seven Western Conference first-round series.
Forsberg, who has 13 goals and 11 assists in 20 regular-season matches against Colorado, snapped a 2-2 tie at 6:08 of the third period by deflecting Roman Josi’s point blast past a helpless Jonathan Bernier. He then doubled the lead at 12:10 with an unassisted marker.
Colton Sissons sealed the outcome with an empty-netter at 18:03 as the Predators notched their 11th straight win over the Avalanche, dating to April 2016. Game 2 of the series is Saturday in Nashville.
