LOS ANGELES -- Drew Doughty's goal with exactly two minutes left -- Los Angeles' third power-play goal of the night -- snapped a tie Saturday night and sent the Kings to a 4-2 win over the Buffalo Sabres before a sellout crowd of 18,230 in Staples Center.
The disheartening loss dropped the Sabres to 0-4-1 on the season. The Kings improved to 3-0-1.
Doughty's goal came four seconds after Evander Kane went off for tripping in the offensive zone. He took a pass from Alec Martinez and whizzed a quick shot home from the left point past Robin Lehner.
The Kings entered the game 0 for 16 on the power play for the season but were 3 for 3 in this one, including two conversions in the third period. The Sabres came in 13 of 14 on the penalty kill and went 0 for 3.
Los Angeles clinched its seventh straight home win over Buffalo on Tanner Pearson's empty-net goal with 14.9 seconds left.
Earlier in the third: Jack Eichel went off for a dubious interference penalty at 5:26 of the third period and the Kings took advantage to take a 2-1 lead as Tyler Toffoli beat Lehner high glove with a quick snapshot off a Jake Muzzin feed at 7:09.
Getting it back: Eichel tied the game at 9:06 with his second of the season, banging home his own rebound after taking a pass in the low slot from Kane. Eichel had his third multi-point game of the season in five attempts.
Breaking News: The Sabres actually scored a goal in the first period, with Zemgus Girgensons notching a tap-in on a 2-on-1 via a Eichel pass to give the Sabres a 1-0 lead at 15:45. It was Girgensons' first goal of the season and gave Buffalo its first lead since the season opener Oct. 5 against Montreal.
Advanced math: The Girgensons goal snapped the Sabres' shutout streak in Los Angeles at 279 minutes, 38 seconds, dating to a goal by former captain Craig Rivet in 2010. Buffalo had suffered four straight 2-0 losses here.
Taking advantage: The Kings got a power play in the second period when Josh Gorges went off for interference and it took them just 46 seconds to capitalize as Dustin Brown scored his fourth of the season by sliding a loose puck under Lehner.
Turn back the clock to 2012 and 2014: The goal was Brown assisted by Jeff Carter, who tapped the puck to him, and Doughty. All three players were key men on the Kings' Stanley Cup teams of '12 and '14.
First meeting with hometown team: Eden native Alex Iafallo made his debut against the Sabres and got nailed for a holding penalty against Eichel in the second period -- while also drawing the Sabres' ire when he got the puck and pumped it through Lehner at the whistle. Iafallo played 18:29, had three shots on goal and was minus-1.
Thank you, Sabres: During television timeouts during the first period, the Kings did video tributes to Buffalo forward Jordan Nolan and Sabres associate coach Davis Payne. Nolan won Stanley Cups here in 2012 and 2014 and got a huge ovation from the crowd while Payne won the '14 Cup.
Also on the big screen: The fans cheered before the game as the Dodgers' NLCS contest against the Chicago Cubs was shown on the jumbotron and gave a big roar when a replay of the hometown team's 5-2 victory was shown.
Up next: The Sabres hit the road for Anaheim right after the game and will meet the Ducks Sunday night at 9 p.m. in Honda Center. The road trip wraps up Tuesday night in Las Vegas.
