"We didn't lose a single puck battle and we didn't turn pucks over. We just did a great job of supporting each other," LaBarbera said after the Kings beat Nashville 6-0 Tuesday night to hand the Predators their sixth straight loss.
"I think earlier in the year, we were turning pucks over in bad spots and losing battles along the walls."
With his teammates playing solid defense in front of him, LaBarbera stopped 17 shots.
The Predators were shut out for the second game in a row. They have been outscored 29-9 during the losing streak, their longest in regulation since they dropped six straight March 10-21, 2002. They have scored only one goal in three games.
"I'm at a loss for words," Nashville forward Jason Arnott said. "We have a lot of soul searching to do.
"Until we come together as a team, we're not going to go anywhere. Tonight we were a totally different team, totally unacceptable. It wasn't the coach's fault, it's us 20 guys in this locker room."
Cammalleri capped the scoring on a power play with 1:20 remaining. Nagy, signed as a free agent over the summer, had made it 5-0 at 9:23 of the third.
Cammalleri opened the scoring 6:09 into the game. Lubomir Visnovsky made it 2-0 later in the period.
Raitis Ivanans and Alexander Frolov each scored in the second period to give Los Angeles a 4-0 lead, prompting Nashville coach Barry Trotz to replace goalie Chris Mason with Dan Ellis midway through the period.
Los Angeles coach Marc Crawford obviously was pleased to see LaBarbera get the shutout.
"Tonight gives Jason a great deal of confidence," Crawford said. "We definitely need our guys to have confidence in their goaltender. He played a strong game and moved the puck well behind the net."
Mason faced 19 shots, and the Kings had 17 against Ellis.
Nashville, which tied for the Western Conference lead with 51 victories last season, won its first two games this season before beginning the skid.
"I didn't expect this," Trotz said of the lopsided loss. "We're doing a lot of talking. We need to quit the talking and just do it.
"The first period set the tone of the game and after that, we just kept burying ourselves."
The Kings won for the third time in four games after slogging through their own five-game losing streak.
