Rene Bourque had two goals and David Desharnais and Brendan Gallagher also scored Friday night, helping the Montreal Canadiens beat the host Tampa Bay Lightning, 4-1, in Game 2 of their Eastern Conference quarterfinal series.
Carey Price stopped 26 shots for Montreal, redeeming himself following a less than stellar performance during a 5-4 overtime win in Game 1.
A second road victory in three nights sends the Canadiens home with a two-games-to-none lead in the best-of-seven series. Game 3 is Sunday.
Bourque and Desharnais scored in the second period after defensive breakdowns left Tampa Bay goaltender Anders Lindback in tough situations. Gallagher made it 3-0 with an unassisted goal in the third period.
Red Wings 1, Bruins 0 - Pavel Datsyuk scored at 16:59 of the third period, moments after Jimmy Howard's best save of the game, and Detroit beat top-seeded Boston Bruins in the opener of their Eastern Conference playoff series.
The Bruins won the Presidents' Trophy for the best record in the regular season but were locked in a tight game in which neither team had many solid scoring opportunities.
The winning goal came when Datsyuk carried the puck from the right side to the left in Boston's zone and put a 30-footer from near the left circle past goalie Tuukka Rask's left glove.
Blues 4, Blackhawks 3 -
Buckle up, Blackhawks fans, this has the makings of some kind of thrill ride.
Trailing the defending Stanley Cup champions late in regulation, St. Louis rallied for a triple-overtime victory in Game 1 of the first round of the NHL playoffs night at Scottrade Center.
Chicago was within 1 minute, 45 seconds of seizing home-ice advantage in the best-of-seven series when Jaden Schwartz scored to tie it up and Alexander Steen eventually notched the game-winner 26 seconds into the third extra period as the Blues snapped a six-game losing skid that ended their regular season.
In a game that pretty much had everything from highlight-reel goals to crunching hits to acrobatic saves, the Blues drew first blood - literally - in the series that will continue Saturday with Game 2 in St. Louis.
"It's not fun to lose those ones," Hawks captain Jonathan Toews said afterward, blood flowing from above his right eye. "When you go the length of a game like that you want to find a way to win. It's disappointing but it's a long series."
Sharks 6, Kings 3 - Host San Jose scored five times during a blistering first two periods to beat Los Angeles in the opener of their first-round playoff series at SAP Center.
Forwards Joe Thornton, Tomas Hertl, Patrick Marleau, Raffi Torres and defensemen Marc-Edouard Vlasic and Brent Burns scored, chasing Los Angeles goalie and playoff nemesis Jonathan Quick in the process.
