The Ottawa Senators know there is little margin for error if they want to upset the Pittsburgh Penguins.
If they don’t slow down Pittsburgh’s potent power play, they'll have a difficult time against Sidney Crosby and the rest of the Penguins.
Paul Martin and Chris Kunitz scored power-play goals and Pascal Dupuis added his sixth goal of the playoffs and the Penguins beat the Senators 4-1 in Game 1 of the Eastern Conference semifinals Tuesday night in Pittsburgh.
‘‘We know it’s a good start, but it’s just like the rest of the playoffs we know it’s just the start,’’ Pittsburgh forward Jarome Iginla said.
A promising one at that.
Evgeni Malkin extended his points streak to seven games with a goal and an assist for the Penguins while Tomas Vokoun stopped 35 shots to win his third straight game since replacing struggling starter Marc-Andre Fleury.
Colin Greening scored for the Senators. Craig Anderson made 26 saves, but Ottawa had no answer for Pittsburgh’s power play.
‘‘Their power play is good,’’ Anderson said. ‘‘We knew that going in and if we want to have good chance to win a game we’re going to have to shoot down their special teams. It’s huge for them. If we’re able to kill those off, it’s a different game.’’
It wasn’t in the opener.
The Senators had the NHL’s best penalty kill during the regular season and turned aside 16 of 19 penalties against Montreal in the first round.
Yet they couldn’t stop the Penguins from going 2 for 4 on the power play to improve to 9 of 24 with the man advantage in the playoffs, the best of the eight teams remaining.
‘‘This power play that they have with all those players, they’re dangerous,’’ Ottawa defenseman Marc Methot said. ‘‘Whether we've got to play with more discipline, whatever that is, whatever the answer is it’s something we have to focus in on.’’
Better hurry up. Game 2 is on Friday night and the Penguins appear to be hitting their stride after needing six games to get by the New York Islanders in the opening round.
‘‘I love the way our team came out and played that game,’’ Pittsburgh coach Dan Bylsma said. ‘‘We’re not just counting on one guy to carry a load . . . we were able to do a lot of good things.’’
The 36-year-old Vokoun made his 713th NHL start on Tuesday, but his first with the stakes this big. Despite admitting to some butterflies when told he would get the starting assignment for Game 1, Vokoun overcame some shaky moments early to settle down.
Having the lead most of the night certainly helped.
Pittsburgh didn’t need to wait long to get a chance to put the power play to work. Ottawa’s Kyle Turris drew a high-sticking penalty before the game was 90 seconds old, and barely a minute later, Pittsburgh jumped in front.
Malkin worked his way into the corner then threaded a pass between two Ottawa defenders to Martin at the point. Martin’s slap shot from the point deflected off Ottawa defenseman Jared Cowen and scooted past Anderson just 2:41 into the game.
The Senators didn’t take long to tie it, evening things at 1 on the kind of soft goal Vokoun had avoided during his two stellar starts against the Islanders.
Kings 2, Sharks 0 — Jonathan Quick made 35 saves in his sixth career playoff shutout, and Los Angeles opened its second-round series with a victory in San Jose.
Slava Voynov and Mike Richards each had a goal and an assist in the defending Stanley Cup champions’ 11th straight victory at Staples Center since March.
With yet another dominant playoff performance by Quick, Los Angeles opened the NHL’s fourth all-California playoff series with its fifth straight victory after an 0-2 start to its title defense.
The Kings’ Conn Smythe Trophy winner allowed just 10 goals in the six-game first round against St. Louis before frustrating the Sharks, whose superior speed and passing produced nothing.
Antti Niemi stopped 18 shots for the Sharks, who swept Vancouver out of the first round.
Game 2 is Thursday.
