BOSTON — After letting a pair of two-goal leads slip away in the second period, the Bruins got the break they needed early in the third and put an end to the Penguins' rallies.
David Pastrnak scored on a breakaway 5:06 into the third, snapping a 3-all tie and giving Boston the lead for good in a 4-3 win Friday.
"Maybe we were a little sleepy, but we get a good break," Pastrnak said. "When you're playing a good way, you get the lucky bounces, and (Friday) went our way. I think we deserved it."
The Bruins extended their winning streak to four straight, their longest of the season. Anton Khudobin, who has been in goal for all four wins, had 17 saves.
Sidney Crosby had a goal and an assist for Pittsburgh, which rallied from deficits of 2-0 and 3-1 to tie it with three goals in the second period. Matt Murray had 30 saves for the Penguins, who lost their third straight and face the Lightning in Pittsburgh tonight.
"I think everybody could be better," Pittsburgh coach Mike Sullivan said. "We can't show up after the first 20 minutes of the game and expect to win games consistently."

Language patrol: The league is trying to get players to clean up their language on the ice at a time sensibilities are heightened, microphones are everywhere and things spread quickly on social media, NHL senior vice president Colin Campbell told the Toronto Star. On-ice officials have been told to remind players about what they say.
"And, giving the players credit, they are much more in touch with what they can and can't say today," Campbell said. "They know that they are being monitored in every possible way today."
Said Lightning GM and Hall of Fame player Steve Yzerman: "What was said 20 years ago isn't acceptable. Not that it was acceptable then; it was tolerated. You have to watch what you say (now). That's probably a good thing."
