Anton Forsberg took over in net for the rest of the night, allowing three goals on 20 shots for Los Angeles, which has lost three straight (0-1-2).
“I thought we played a good 40 minutes,” Kings defenseman Drew Doughty said. “Third period, just gave up a little too much, obviously. Got to put a 60-minute game together.”
Back gave the Stars a 2-1 lead at 6:12 of the third period by redirecting Radek Faksa’s shot from the blue line. The goal was Back's first since his season debut on Oct. 26 (23 games).
“Great to see ‘Backer’ get one, too,” Duchene said. “I mean, that’s a guy that works so hard every night. Huge on the kill. That whole line chips in with the game-winner, that’s huge for us.”
Rantanen made it 3-1 at 16:11 with a snap shot from the slot off a rush before Johnston scored an empty-net goal at 19:28 for the 4-1 final.
Andrei Kuzmenko put the Kings ahead 1-0 during a 5-on-3 power play at 11:03 of the second period. DeSmith hesitated playing the puck after it came back to him off the face-off, allowing Kuzmenko to race in and score from close range.
“He’s just been so rock-solid all year, and those things happen,” Dallas coach Glen Gulutzan said of DeSmith. “He just rebounds right away. I love his mental toughness.”
Duchene tied it 1-1 at 15:42, charging the crease and getting behind Los Angeles forward Alex Turcotte and Doughty to put in a pass from Rantanen.
It was Duchene’s first point in five games after missing 24 because of a concussion.
“You could see his timing is getting back, and he created some offense,” Gulutzan said. “That’s what ‘Dutchie’ is going to bring for us when he gets his motor up and running completely, is just against these teams who play man-on-man, he can hold on to pucks. He’s a heavy body, and he can twist and turn and buy time and make little plays in tight spaces, so it’s going to help increase our O-zone time.”
