ST. LOUIS -- On the outside, Los Angeles goaltender Jonathan Bernier appeared calm, cool and collected Monday night.
But on the inside, the butterflies were dancing around as he made his first start of the season.
"That's my game, I may look not stressed -- but sometimes inside I am," he said.
Bernier certainly didn't show the nerves. He had 21 saves and Jeff Carter scored twice to lead the Kings to a 4-1 win over the St. Louis Blues before 14,498 at Scottrade Center.
Los Angeles (4-5-2) won for the second time in four games and completed a five-game road trip with a 2-3 record.
St. Louis (6-5-1) lost for the fifth time in a row, its longest losing streak since dropping five straight from Jan. 2 to Jan. 12, 2011. The Blues have been outscored 26-11 during the skid.
Bernier stopped 10 shots in the third period and protected a 3-1 lead. He gave up a power-play goal to Alex Steen with 43 seconds left in the second period but buckled down to post his first win since March 17, 2012, when he beat Nashville 4-2.
"He was solid, he didn't give up any second opportunities," Los Angeles coach Darryl Sutter said.
Bernier surrendered four goals on 21 shots in a relief appearance on Feb. 2 -- his only action before Monday night.
This time, he knew well in advance that he would be spelling regular goalie Jonathan Quick, who was given the night off.
Bernier made the most of the rare opportunity.
"He's been itching to get in there," Carter said. "He swallowed up pucks and did a great job for us."
Carter took care of the offensive chores with his first multi-goal effort since scoring twice in the Stanley Cup-clinching Game 6 win over New Jersey last season.
"I remember that game," he said with a smile.
Carter scored in the first eight minutes of the first period and then again in the first three minutes of the second period to stake the Kings to a 2-0 lead. Los Angeles grabbed the early jump and never let up on the gas pedal.
"It's something we've kind of been talking about, playing with a lead," Carter said. "We haven't done it much this year."
Davis Drewiske and Jarret Stoll also scored for the defending Stanley Cup champions.
Carter converted on a two-on-one off a perfect pass from Slava Voynov to make it 1-0. Carter scored again on a backhand shot along the ice in the second period for his sixth of the season.
Drewiske scored less than six minutes later to make it 3-0.
St. Louis goalie Brian Elliott gave up four goals in the first 18 shots and has surrendered 18 goals on 86 shots in his last four games. He led the NHL in goals-against (1.56) and save percentage (.940) last season. He currently sits at 3.57 and .849.
The Blues activated Jaroslav Halak from injured reserve on Sunday, but coach Ken Hitchcock elected to start the slumping Elliott.
"I don't want to make any excuses," Elliott said. "It starts from the goaltending out. Once you start doing things on a high level, that's when things start turning around."
The Blues, who have scored at least one power-play goal in each of the last six games, begin a three-game road trip Wednesday in Detroit.
St. Louis, which won six of its first seven this season, has lost four successive home games for the first time since Jan. 23-Feb. 6, 2010.
"This was the homestand from hell," Hitchcock said. "Now, we've got to take this on the road and be more accountable."
