Tkachuk and Jonah Gadjovich then scored 34 seconds apart to give Florida a 2-0 lead, each goal coming in the 40 seconds following a successful penalty kill.
“A three-goal swing in a very, very short period of time, critically important,” Maurice said. “It's such a dangerous team. ... Their plus-10 [goal] differential, I think they're the only team on the outside (of the Stanley Cup Playoffs) with that. They're hard to play against.”
Tkachuk scored at 4:28 on a wrist shot from the left face-off circle off a pass from Rodrigues. Gadjovich extended the lead at 5:02, deflecting a shot from Brandon Montour.
“You get one disallowed and then they score two right off the top,” Penguins captain Sidney Crosby said. “So that’s probably not what you’re looking for. But there’s a lot of time left to get back in the game and we were unable to do that.”
Aaron Ekblad made it 3-0 on the power play at 8:27 with a wrist shot from the right circle.
Lundell pushed it to 4-0 at 13:02, redirecting a pass from Tkachuk at the left post.
“When you get that lead like that, it's never easy to keep it,” Ekblad said. “We did a really good job of being resilient and finding a way."
