Pyotr Kochetkov made 17 saves for the Hurricanes (47-17-9), who have lost three of four (1-2-1) and remained three points ahead of the New Jersey Devils for first place in the Metropolitan Division with one game in hand.
"Not a lot of spark to our game. Didn't play it the way we'd like to play it," Carolina coach Rod Brind'Amour said. "It wasn't like we were giving up a boatload of chances, but we weren't getting enough to get a lot of emotion in the building."
Stamkos gave the Lightning a 1-0 lead at 5:58 of the second period, redirecting Mikhail Sergachev's slap pass five-hole on Kochetkov from near the left post.
"Just trying to get open there, and [Sergachev] had a good heads-up play and squeaked on through there," Stamkos said. "It was nice to get on the board. After that, we responded pretty well."
