Siegenthaler tied the game at 4-4 at 8:36 of the third period with a wrist shot from the left-wing boards. It was his first goal in two seasons with the Devils (60 games) and first in 95 games, since Dec. 20, 2019, with the Washington Capitals.
"It feels good; it's been a while," Siegenthaler said. "I'm happy, but it's not the same if you lose."
Kirby Dach scored on a backhand at 14:04 for a 5-4 Chicago lead.
"It was huge," Blackhawks coach Derek King said. "That was real big. I think just for the fans. I mean, we're competing, we're trying and it just wasn't working, and then it was an exciting game. Got the fans out of their seats. Great to see [Lankinen] hang in there and survive it and get us a win. We had contributions from a lot of bodies."
