Pittsburgh Penguins' Evgeni Malkin (71) changes direction in front of New York Islanders' Keith Aucoin (10) during the second period of Game 1.
Pascal Dupuis scored twice, Marc-Andre Fleury made 26 saves, and the top-seeded Pittsburgh Penguins opened the playoffs with a 5-0 romp over the New York Islanders on Wednesday night.
Beau Bennett, Kris Letang and Tanner Glass also scored for the Penguins, who had no trouble against the upstart Islanders even with star Sidney Crosby sidelined by a broken jaw. Crosby has been out since he was struck by a puck on March 30 in a game against the Islanders.
Fleury earned his sixth career playoff shutout.
The Penguins, the No. 1 seed in the Eastern Conference, beat Evgeni Nabokov four times in the game's first 22 minutes, including goals by Letang and Dupuis 32 seconds apart early in the second period to send Nabokov to the bench after he stopped just 11 shots.
Kevin Poulin came on in relief and surrendered a soft goal to Glass.
Game 2 is Friday in Pittsburgh.
BRUINS 4, MAPLE LEAFS 1
Nathan Horton scored the go-ahead goal late in the first period, and Boston used a revived offense to beat Toronto in the playoff series opener.
The Bruins scored more than three goals for the first time in 10 games. They closed the regular season on a 2-7 skid that dropped them to the No. 4 seed in the Eastern Conference.
That set up a first-round matchup with fifth-seeded Toronto, the first time the teams have met in the postseason since 1974. The Maple Leafs, who are in the playoffs for the first time since 2004, lost four of their last six regular-season games.
Wade Redden also scored in the first period for Boston, and David Krejci and Johnny Boychuk added goals in the second.
James van Riemsdyk had given Toronto a 1-0 lead with a power play just 1:54 into the game.
Game 2 is scheduled for Saturday night in Boston, where the Bruins have won six straight against the Maple Leafs.
SHARKS 3, CANUCKS 1
Dan Boyle and Patrick Marleau scored in the third period for San Jose, which rallied to beat Vancouver in the first-round Western Conference series opener.
Boyle and Logan Couture both had a goal and an assist, and Marleau pushed San Jose's lead to 3-1. Antti Niemi made 28 saves for the Sharks, who were outshot 30-28.
Kevin Bieksa scored for the Canucks before a disappointed white-towel-waving sellout crowd. The loss spoiled a strong effort from goalie Roberto Luongo, who earned the start after Cory Schneider didn't recover in time from an undisclosed injury.
The Canucks were the first home team to lose in the first six games of this year's playoffs.
