"Our fight on the puck was not at a playoff level if you expect to win this time of year, so it's a little concerning," Kings coach John Stevens said. "We've just got to decide as a group where we're going to go from here. It's tough hockey this time of year."
Robert Bortuzzo gave St. Louis a 1-0 lead at 3:03 of the first period during a 4-on-4.
"It helps to get that first goal, get a big boost," Schwartz said. "We just never looked back and we stayed aggressive."
Colton Parayko made it 2-0 at 8:53. Jonathan Quick poke checked the puck away from Patrik Berglund, but Parayko gathered it in the right circle and scored into an open net.
Doughty made it 2-1 at 13:13 of the second period. Pietrangelo gave the Blues a 3-1 lead at 17:08, scoring from in close after the getting the puck off a poke check from Quick.

"When we're jumping on the back end, it pushes teams back because they know we're coming, we're an extra threat," Pietrangelo said of the Blues defensemen. "Those forwards [have] to keep an eye on us, and, a lot of times, that opens up more space for the forwards."
Barbashev scored to make it 4-1 at 19:34, splitting Doughty and Derek Forbort before scoring five-hole on Quick.
Quick, who made 25 saves, was replaced by Jack Campbell to start the third period. Campbell made 11 saves.
Tarasenko (at 26 seconds) and Brodziak (at 58 seconds) scored on the first two shots Campbell faced to give the Blues a 6-1 lead before Schwartz made it 7-1 at 12:11.
Brown scored to make it 7-2 with a power-play goal with 15 seconds left.
"I think it gave us a good boost," Allen said. "You could tell in the third period. It was impressive. It was impressive to watch against a really good team who's playing really well. From the start of the game to the end, it was a job well done."

"What you hope now is that some guys can build some confidence off of that and carry a little bit of momentum into our next one. We know our next one is going to be a real tough challenge, but it's nice with an afternoon game; we have the rest of the night to enjoy this one." -- Blues coach Mike Yeo

"You're not going to take anything positive out of that hockey game. The only thing you're going to take out of that hockey game is how tough it is this time of year. Lot of guys here know that, and there's lots of guys that've got to learn that, but as a group, we've certainly got to acknowledge it." -- Kings coach John Stevens
