The Pittsburgh Penguins scored four unanswered goals, including three in the second period, to earn a 4-2 win over the host Boston Bruins on Tuesday night.

Former Bruin Danton Heinen scored twice in a 28-second span to turn a two-goal deficit into a tie game before Sidney Crosby tallied the winning goal on the power play for Pittsburgh, which ended a four-game losing streak and is 7-1-3 in its last 11 games.

Bruins captain Patrice Bergeron, who assisted on the first of two goals by David Pastrnak, hit his head on the boards in a collision with Crosby with less than 12 minutes to play. He didn't return from the locker room after skating off under his own power.

Metropolitan Division All-Star goalie Tristan Jarry made 43 saves for the Penguins, including a flashing glove stop on Tomas Nosek's shot through traffic that would have tied the score with 4:29 left. In the final minutes, Bruins star Brad Marchand was penalized for seven minutes for punching Jarry.

Penguins All-Star Jake Guentzel had two assists. Pastrnak scored both Boston goals in the first period, both assisted by Taylor Hall.

The Bruins peppered Jarry with 17 of their 45 shots in the opening frame, taking the lead just 2:01 in when Pastrnak pumped home a one-time feed from Hall on the power play. Boston has now scored at least one man-advantage goal in 10 of its last 11 games.

Pastrnak teamed up with Hall again to double Boston's lead at the 15:34 mark as the Czech winger batted a rebound out of mid-air at the right crease. The second goal ensured Pastrnak's 40th career two-goal game.

Heinen evened the score with Pittsburgh's first two goals, 28 seconds apart -- the fastest two tallies by a single Penguin since 2000.

Heinen finished a nifty backhand pass from Brock McGinn after driving to the net at 4:18. His game-tying shot from the bottom of the right circle bounced in off Boston goalie Jeremy Swayman's back.

Pittsburgh took its first lead with a power-play goal at 12:53. Crosby buried Bryan Rust's centering feed from behind the goal line. It was Crosby's 499th career goal.

Rust's empty-net goal capped the scoring with 1:29 to play.

Swayman finished with 21 saves.
