"The top guys need to put some goals in the net, and it's no secret that we've kind of struggled at that," Carter said. "For us to win games, we're going to have to get going here."
The five-game skid is the first since Jan. 2-12, 2011, for the Blues, who began the season 6-1. It's their first five-game losing streak at home since Jan. 23-Feb. 6, 2010.
"This is the homestand from hell," Hitchcock said. "We lost our goalie, we didn't play as well and now we've got to take this onto the road, and we've got to be much more accountable to each other."
Carter tapped in a backhander on a break-in with Slava Voynov at 8:31 of the first, just the Kings' fifth first-period goal of the season, then got behind defenseman Ian Cole for his sixth of the season early in the second. Drewiske was wide open in the slot off a feed from Dustin Brown.
The Kings are 89-1-10 their last 100 games when leading after two periods, and got insurance on Jarrett Stoll's second goal of the season that made it 4-1 early in the third. Voynov earned his second assist on the play.
Elliott entered the game 3-4-1 with a 3.51 goals-against average and Hitchcock said after a 6-5 shootout loss to the Ducks on Saturday that he'd start rookie Jake Allen against Los Angeles if Halak wasn't ready to go. Allen was assigned to Peoria, Ill., when Halak, 3-0 with a 2.10 goals-against average and two shutouts, was activated on Sunday.
The Kings entered as the NHL's lowest-scoring team and matched their season best for goals.
