LOS ANGELES -- The Los Angeles Kings jumped all over the Toronto Maple Leafs early but had to hold on late to match the best start in their history.
Tyler Toffoli scored twice, Tanner Pearson had three assists, and Michael Amadio scored his first NHL goal to help Los Angeles to a 5-3 win against the Maple Leafs at Staples Center on Thursday.
Michael Cammalleri had a goal and an assist, and Trevor Lewis scored for the Kings (10-2-1), who equaled the 21 points Los Angeles had through 13 games in 1980-81. Jonathan Quick made 33 saves.

The Kings took a 5-0 lead when Toffoli scored his second goal of the second period at 16:32.
"I think we came out right away and we played really hard and played fast and played our game," said Los Angeles forward Adrian Kempe, who had an assist.
Auston Matthews scored his 10th goal on his first NHL penalty shot, and Curtis McElhinney made 23 saves for the Maple Leafs (8-6-0), who have lost four of their past five games. Morgan Rielly and Connor Brown each had a goal.
Matthews shot over the net on a second penalty shot with 1:19 remaining after Kings defenseman Jake Muzzin was called for delay of game for intentionally dislodging the net. Matthews is the fourth player in NHL history to attempt two penalty shots in one game.
The Maple Leafs, who were coming off a 3-1 win at the Anaheim Ducks on Wednesday, allowed three goals in the first period.

"You just got to be ready," Toronto coach Mike Babcock said. "It's a back-to-back night. We got in early, we ate, we should've been fresh. There should have been no issue, and yet we made those mistakes in the first period."
Defenseman Jake Gardiner lost his footing trying to control a pass in the Maple Leafs zone and turned over the puck to Pearson, who found Amadio for a wrist shot past McElhinney and a 1-0 Kings lead at 2:34.
It was Amadio's first NHL point in his fourth game.
"It was a pretty indescribable feeling, but there was a lot of emotion going through my body," Amadio said. "Great pass by [Pearson]."
Cammalleri put the Kings ahead 2-0 with a power-play goal at 4:58.

Lewis scored his fourth goal with 36 seconds remaining to make it 3-0. The Kings got a sustained push from the line of Lewis, Cammalleri and Nick Shore, who returned after missing three games with an undisclosed injury. Shore eventually found Lewis for a sharp-angled shot that beat McElhinney.
"The play at the end of the period where they cycle, cycle, cycle and end up scoring a goal, those to me are big momentum-builders for you," Kings coach John Stevens said.
Toffoli scored on the power play at 14:31 of the second period to make it 4-0. After scoring 2:01 later, he has five goals in his past four games.
On his first penalty shot, Matthews beat Quick over his glove with a backhand to cut the Kings lead to 5-1 with 2:10 remaining in the second. Anze Kopitar was called for hooking Matthews on a breakaway.
Rielly scored with 1.5 seconds left in the second to make it 5-2.
Brown redirected Gardiner's shot past Quick eight minutes into the third period on the power play to get the Maple Leafs within 5-3. Stevens challenged that Toronto forward Patrick Marleau interfered with Quick, but the goal was upheld after video review.
Brown has scored a goal in two straight games.
"They had a great start, and turning the puck over like that in the first and second is not going to get it done," Gardiner said.
