PITTSBURGH -- Kris Letang scored twice in the third period to help the Pittsburgh Penguins to their fifth straight win, 4-2 against the Dallas Stars at PPG Paints Arena on Friday.
Patric Hornqvist had a goal and two assists, and Matt Murray made 22 saves for the Penguins (6-2-0), who have outscored their opponents 23-11 during the winning streak. Each of the five wins has come without injured forwards Evgeni Malkin (lower body), Alex Galchenyuk (lower body), Nick Bjugstad (lower body) and Bryan Rust (upper body).
"I think every guy that's coming back from injuries is going to get in line and play the same way," Letang said. "We're trying to establish an identity for our team. I think that's what we're starting to build on right now."

Roope Hintz and John Klingberg scored, and Anton Khudobin made 29 saves for Dallas (1-7-1), which has lost five in a row and been outscored 17-7 in that stretch.
"You can't drive passion into people," Stars coach Jim Montgomery said. "You can try everything. You can try motivational tactics. You can try everything, but it has to come from within. Ultimately, if there's a puck between you and I, I'd bite your leg off to get it. That's the attitude you have to have. Anton had that competitive spirit tonight that we need to permeate throughout our lineup."
Letang, who has 10 points (four goals, six assists) in eight games, gave the Penguins a 2-1 lead at 6:34 of the third. He stick-handled around Joe Pavelski and waited for Tyler Seguin to slide by in an attempt at a blocked shot before shooting under Khudobin's right pad.
"Not much was working, as far as results," Seguin said. "[Pavelski] goes and slides. Then, for whatever reason, I go and slide too, and the guy just walks in on a breakaway. That just can't happen."
Hornqvist made it 3-1 when he deflected a shot from Brian Dumoulin at 10:20 of the third before Klingberg cut it to 3-2 with a wrist shot from along the right boards at 12:01.

Pavelski nearly tied the game with Khudobin pulled for the extra attacker when he redirected Andrej Sekera's wrist shot from the right point, but the puck hit the post with 1:08 remaining.
Letang scored into an empty net to make it 4-2 with 22 seconds left.
Hintz put the Stars ahead 1-0 at 5:10 of the second period. After a pass from Jamie Benn went off Penguins defenseman John Marino's stick, Hintz got to the puck for a breakaway and shot through Murray's five-hole.

Jared McCann tied it 1-1 at 17:36 of the second when he redirected a slap shot from Marcus Pettersson. McCann missed the previous game, a 3-2 overtime win against the Colorado Avalanche on Wednesday, with a lower-body injury.
"I thought Jared had a good game," Penguins coach Mike Sullivan said. "He's got a nose for the net. He can score. That goal was a big goal for us. I thought we were playing a pretty good hockey game, and we were down 1-0. I thought that was an important goal for us."
They said it
"I think we're not angry enough. That's what I think. I think we played the first two periods really good. We outhit them. Maybe we didn't outshoot them, but we outhit them. Played pretty good hockey. Something went wrong. ... What else can you say? We just got another 'L.' I don't know. We just have to keep going and do something." -- Stars goalie Anton Khudobin
"I think we've been playing great hockey. We're always five guys on the right side of the puck. We're playing against good teams too. It's hard. They want to transition fast, but we were always in their face. ... Playing for each other. It's fun right now." -- Penguins forward Patric Hornqvist
