It was Pittsburgh's NHL-leading 13th shorthanded goal allowed this season.
"To me, [shorthanded goals] don't really feel different," DeSmith said. "I was pretty happy with the play I made on it. I was kind of all over it and it just ramped up my stick and under my arm, and then off my knob and in, or something crazy. ... Obviously, I want to have those for the power-play guys and not give up those shorthanded goals in a game like that when we need the save."
Hertl scored his second power-play goal of the first period to extend the lead to 3-0 at 13:19. Joe Pavelski passed to Labanc, who quickly sent a pass off Penguins forward Matt Cullen to Hertl above the crease.
"[The Penguins] are a really tough team," said Hertl, who has scored nine goals in his past 10 games. "I'm just happy that we won. We just started a road trip, and it was a huge game for us. We need this game before we have the three tough games coming up."
Burns made it 4-0 with a one-timer on a 5-on-3 with 3:09 remaining in the third period.
