Jonathan Bernier was solid with 21 saves in just his second start of the season for the Kings. Los Angeles outscored the Blues, 15-6, while eliminating them in five games in the second round of the playoffs last spring en route to the Stanley Cup finals.
Carter tapped in a backhander on a break-in with Slava Voynov at 8:31 of the first period, 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. Davis Drewiske was wide-open in the slot off a feed from Dustin Brown and made it 3-0 in the second period.
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.
Carter's last two-goal game during the regular season was March 3 against Anaheim.
