PITTSBURGH — Evgeni Malkin returned and woke up the Pittsburgh Penguins' slumbering offense.

Playing for the first time in eight games following a shoulder injury, Malkin had three assists. Pascal Dupuis scored his second goal of the game 1:24 into overtime and Pittsburgh snapped its four-game losing streak with a 6-5 win over the Boston Bruins on Saturday night.

"We were missing Geno," Dupuis said. "He played great for us. Obviously, it was a big boost for us for him to come back. He played well. It looked like he didn't miss a shift."

Dupuis scored when goalie Tim Thomas mistakenly left a puck along the boards, miscommunicating with defenseman Dennis Wideman. Pittsburgh's Jordan Staal picked up the puck and fed it to Dupuis, who tucked in his 100th NHL goal and fifth this season.

"I don't know what happened behind the net, but I ended up with the puck in the slot and basically just tapped it in," Dupuis said. "One-hundredth goal of my career, game-winner, overtime, I'll take it."

The Penguins' Bill Guerin sent the game to overtime when he scored with 0.4 seconds left in regulation off a feed from Malkin.

The Bruins, 2-0-3 in their past five, scored twice during the final 5:47 of regulation to take their only lead. David Krejci's 5-on-3 goal tied it, and Marco Sturm put Boston ahead with 2:29 left.

Sidney Crosby had a goal and two assists, and Jay McKee and Mark Eaton also scored for the Penguins, who netted only three goals during their skid. Pittsburgh scored once in the 209 minutes, 9 seconds before Saturday's game.

Penguins coach Dan Bylsma put Malkin on a line with Crosby, something the Penguins rarely do. Pittsburgh responded by matching a season high for goals.

"I know we get the message when we're together," Crosby said. "We know we have to create things. It's hard for them to key on one of us when we're together. Geno did a great job."

"I think after the last four games, this was a big moment for me and the team," Malkin said.

The Bruins had scored 11 goals in their previous eight games and were shut out in their last two road games.

This game turned into a shootout, capped by a frantic final 13 minutes in regulation and overtime.

"We scored goals, yeah," Boston defenseman Derek Morris said, "and we got a point, which was nice, but that's not our system we're going to play. We did things we don't normally do and we did them all in one game. We're lucky to get a point."

Eaton gave the Penguins their fourth lead when he finished a setup from Crosby with 11 minutes left.

The Penguins went 0 for 3 on the power play and are 0-for-29 in eight games.
