LOS ANGELES — Tampa Bay's spectacular start to the season hasn't been slowed one bit out West.

On back-to-back nights at either end of California, Steven Stamkos and Nikita Kucherov led the speedy Lightning to blowout wins over two NHL contenders.

Stamkos, Kucherov and Alex Killorn each had a goal and an assist during Tampa Bay's four-goal first period, and the NHL-leading Lightning beat the Los Angeles Kings 5-2 late Thursday in an early meeting of division leaders.

One night after a 5-1 win in San Jose, the Lightning were just as good in LA. Kucherov started the Lightning's avalanche of goals during 4-on-4 play midway through the opening period at Staples Center when he slipped out on a breakaway to accept a pass from Stamkos.

Before they were done, the Lightning had four goals in 2:02.

"I can't remember the last time we came in here and played this well against these two teams back-to-back," Killorn said. "There's a ton of confidence in this room. We realize our top guys are doing really well, and they help to feed our whole team. Everything seems to be clicking right now."

Victor Hedman also scored during a surge that buried Jonathan Quick and the Pacific Division-leading Kings, who lost at home in regulation for the first time this season.

"Usually in San Jose and here, we've had some really tough nights," said Hedman, who also had an assist in his third multi-point performance in five games. "To come in here and play the way we've played the last two games, it's really satisfying. It says a lot about the character of this team."

Vladislav Namestnikov added a third-period goal and Peter Budaj made 22 saves against his former Los Angeles teammates. The Lightning improved the NHL's best record to 13-2-2 with their third straight victory overall.

Stamkos kept the overall NHL scoring lead with 30 points, but Kucherov is right behind with 29. The Russian forward leads the NHL with 16 goals in 17 games.

"It reminds me of the team we had in the (Stanley Cup) Final year (in 2015)," said Kucherov, who has eight points in the last three games. "We have a lot of similarities, and we're playing fast. We play with a lot of toughness and a lot of fun, and are fun to watch."
