Morgan Frost scored twice, and Tippett had a goal and an assist for the Flyers (7-7-1), who were coming off a 6-3 victory at the Anaheim Ducks on Friday.
Cam Talbot allowed four goals on 26 shots for the Kings (8-3-3), who were 6-0-2 during the point streak.
“I don’t think there’s many nights so far this season where we’ve been outworked and, what’s the word I’m looking for, out-committed, and we were that tonight,” Los Angeles coach Todd McLellan said.
Tippet put Philadelphia ahead 1-0 at 14:59 of the first period, scoring with a backhand on a breakaway that trickled under the right arm of Talbot.
Frost made it 2-0 at 6:26 of the second period when his centering pass from behind the net deflected in off the skate of Kings defenseman Jordan Spence and Talbot’s glove. It was his first goal of the season.
“I’d like to say I tried to bank it off his feet on purpose, but no, definitely not,” Frost said. “Got a fortunate bounce there, and I’d like to think I’ve been working hard being in and out of the lineup, keeping a positive attitude. So maybe that’s the bounce that I got for that.”
Frost extended the lead to 3-0 at 16:30 when he redirected Nick Seeler’s shot from the blue line.
“It’s a weird game, hockey is, but I think if you don’t cheat it and stay honest with yourself and just keep working hard, I think those are the bounces you can get,” Frost said.
Carl Grundstrom cut it to 3-1 at 18:06 of the second with a wrist shot from the high slot.
“I think I’m shooting more and I try to be more in good spots to score as well, so I think that’s been key for me,” Grundstrom said.
Cam Atkinson pushed it to 4-1 at 7:04 of the third period, scoring with a one-timer from the low slot off a pass from Sean Couturier from the right post.
Adrian Kempe got Los Angeles to within 4-2 at 9:50, tapping in a touch pass from Quinton Byfield at the left post.
“They didn’t need a lot of chances, but the ones they got they scored on,” McLellan said. “We can beat our team up, which we have to a little bit, they deserve it, but I also have to tip my hat to their team. They played a real good game.”
