Mike Sullivan said that he didn't "think the score was an indication of how close the game was."
The scoreboard read 5-1 in the Lightning's favor on Tuesday night at PPG Paints Arena, the Penguins' first regulation loss of the season.
The game was tightly-contested and hard-fought for much of the 60 minutes, but it took just a few seconds for the momentum to swing in the Lightning's direction just enough to put the game out of reach for the Penguins.
The Lightning came into the game on a three-game losing streak, including a tough 5-1 loss to Buffalo on Monday night.
