TAMPA -- Steven Stamkos scored his first goal in almost a year, and Slater Koekkoek scored the first two goals of his NHL career to help the Tampa Bay Lightning defeat the Pittsburgh Penguins 5-4 at Amalie Arena on Thursday.
Stamkos' goal, his first since Nov. 15, came on a power play and gave the Lightning a 3-1 lead at 3:49 of the second period. The center missed 65 games last season with a lateral meniscus tear in his right knee.
"I knew it was a matter of time, so I wasn't losing any sleep over it," Stamkos said. "I'm just happy to be playing hockey again and glad to be part of some wins here. I thought we came out strong against [the Washington Capitals, a 4-3 overtime win Monday] and followed that up for the most part. That's two good teams that have come in here and we've gotten two wins, so we'll look to build on that."

"I was joking that if me, [Tyler] Johnson and Killorn were on a 3-on-1, who would want the puck, and I would probably be your last option," Koekkoek said. "I was looking for [Tyler] back door, but the goalie was right on me, so a little fake and then he opened up his five-hole."
Hunwick made it 5-4 when he scored on the rebound of a shot by Greg McKegg at 10:01 of the third period.
Sheary made it 3-2 at 8:58 of the second period when he broke into the zone off a pass from Chad Ruhwedel and beat Vasilevskiy with a wrist shot high on the stick side. Kucherov gave the Lightning a 4-2 lead at 9:49, and Rust scored a power-play goal at 14:24 on the rebound of a shot by Guentzel to make it 4-3.
Koekkoek's first NHL goal gave the Lightning a 1-0 lead at 6:07 of the first period. His slap shot from the point hit the stick of Penguins forward Tom Kuhnhackl and trickled past Niemi. The 23-year-old defenseman was playing his 43rd NHL game.

The Penguins tied the game 1-1 at 13:46 when Guentzel tipped in a centering pass from Kris Letang. It was Letang's 300th NHL assist in 608 games.
Hedman put the Lightning ahead 2-1 with a power-play goal that beat the buzzer at the end of the first period. Video review showed the shot crossed the goal line with 0.1 seconds remaining.
"We let them get out of range a couple of times, especially when they went up 5-3, I think that was a bit of a dagger for us," Sheary said. "We fought hard, especially in the third, had a lot of scoring chances, unfortunately we weren't able to put another one in."
Goal of the game
Kucherov took a feed from defenseman Braydon Coburn and his wrist shot from above the left circle beat Niemi over his glove to the far post.

They said it
"We tried hard to play a more disciplined game in a game that wasn't. We don't want to be a team that trades chance for chance because you can't control your destiny if you play that way. We have to be more of a team that controls territory, that controls the momentum, that has more of a defensive conscience in mind so that we have a better opportunity to control the outcome." -- Penguins coach Mike Sullivan
"These are good teams, so anytime you can beat a good team it's going to give you confidence, especially to respond the way we have after that tough effort [against the Florida Panthers, a 5-4 loss Saturday]. We've responded well and now we'll continue to work to get better." -- Lightning captain Steven Stamkos
