Bunting gave Pittsburgh a 1-0 lead at 2:45 in the first period on a wraparound from the right post.
Joe Pavelski tied it 1-1 at 7:16 when his rebound attempt deflected in off of Pittsburgh defenseman Marcus Pettersson at the top of the crease.
“They were opportunistic around the net,” Bunting said. “We knew that was going to be a tough area to defend. They scored a few goals there. I think that’s what hurt us. On the rush as well, they were good in transition. I think we could have done a better job of slowing them down.”
After Benn’s two goals, Sam Steel extended the Dallas lead to 4-1 at 4:37 of the third period on a shot from the high slot, chasing Jarry.
“I think it’s just little things we’ve been trying to build all year. Really grinding them in the [offensive] zone and working teams down,” Steel said of his line (with Craig Smith and Radek Faksa), which has scored in seven of the past nine games. “It seems like the last couple of games, we’ve been getting goals late in the game. That comes from us doing the little things right and grinding them down and capitalizing. It’s been a nice little stretch, and we’re just trying to create momentum.”
Rickard Rakell cut it to 4-2 at 11:03 when Malkin fed him at the top of the crease from behind the net.
“I don’t think anyone was quitting. We had our effort there, had some chances [that] just weren’t necessarily going to the net,” Bunting said. “[Rakell] had a big one, we just couldn’t find the next one.”
