Ryan Smyth scored the Kings' first power-play goal in eight games and Andrei Loktionov added a goal, helping Los Angeles beat Boston 2-0 on Monday night for its fifth straight victory over the Bruins.
The teams' previous four meetings had all gone to overtime or a shootout, including the Kings' 4-3 victory on Nov. 20 after they blew a 3-0 lead on the road.
Los Angeles has won two straight after going 3-13 in its previous 16 games, a plunge that dropped it from being one of the top teams in the West to a club fighting for a playoff berth.
Smyth gave the Kings a 1-0 lead at 10:50 of the first period, ending an 0-for-22 power-play drought that spanned the previous seven games. He scored his 18th goal on a rebound of Jarret Stoll's one-timer after Boston's Zdeno Chara was sent off for hooking.
The Kings outshot Boston 25-20 through the first two periods, but had only one goal to show for it.
That changed at 3:30 of the third, when Loktionov scored from up close off a rebound of Dustin Brown's shot for a 2-0 lead.
Jonathan Quick made 34 saves to earn his 21st victory of the season and 13th career shutout.
Better on the road than at home this season, the Bruins came in with a 6-2-0 record in their previous eight games, having scored at least six goals in four of their seven. But they went 0-for-3 on the power play.
Goalie Tim Thomas had been equally as good, with an 8-0-2 mark in his last 10 games. He made 32 saves before being pulled for an extra attacker with 1:57 remaining.
The Bruins got bad news earlier Monday, when center Marc Savard was diagnosed with a moderate concussion as the result of a hit by Colorado's Matt Hunwick on Saturday. The team said he flew back to Boston and there's no timetable for his return.
Savard sustained a concussion in a game against Pittsburgh last March, and the injury kept him out of the rest of the regular season. He returned for the second round of the Eastern Conference playoffs.
Because of post-concussion syndrome, Savard missed the first 23 games of this season and didn't play his first game until Dec. 2 against Tampa Bay. He has two goals and eight assists in 25 games.
Notes: It was the Bruins' first shutout loss since a 3-0 defeat to Anaheim on Dec. 20. ... The Kings earned their first shutout victory since beating San Jose 4-0 on Dec. 27.
