ST. LOUIS — Teammates and friends in the minors, Los Angeles Kings rookies Calvin Peterson and Matt Luff pulled off NHL firsts in the same game.

Peterson earned his first shutout and Luff scored his first goal, leading the Kings to a 2-0 victory over St. Louis on Monday night — hours before the scuffling Blues fired coach Mike Yeo.

"It's unreal," Luff said. "We were talking when I gave him a hug on the ice about that. Couldn't have picked a better day for it to happen with him getting his first shutout. We talked about it on the plane. He's probably one of the best kids so I'm happy it happened for him."

Peterson, making his third start for the Kings, stopped 29 shots. He is the 24th rookie goaltender to start a game for Los Angeles. In college at Notre Dame and in the minor leagues, Peterson had 20 shutouts.

"On the personal side, to get the shutout was very cool," Peterson said. "And for Luffer to get his first (goal) was very cool, too. So it was an all-around great night."

Not for the Blues.

Following the team's latest defeat, St. Louis general manager Doug Armstrong named Craig Berube interim coach. At 7-9-3, the Blues are in last place in the Central Division, and their 17 points rank next-to-last in the NHL — ahead of only Los Angeles.

The 45-year-old Yeo joined the Blues as an assistant in 2016 after five seasons with Minnesota.

The Kings, last in the Pacific Division, had lost four of five before beating St. Louis in a game featuring teams with the worst records in the Western Conference.

Interim coach Willie Desjardins said it was a good win for the Kings.

"They're hard to play against," Desjardins said. "They had a few chances. I thought we played pretty good overall."

The Blues have lost four of their last five. This marked the third time they were shut out this season.

"It's hard to win if you don't score goals," Blues forward Vladimir Tarasenko said. "I have no words. We're trying hard, maybe too hard. If we don't score, it's zero in every game and it's really frustrating."

Los Angeles went up 1-0 at 8:18 of the second period. Luff, a 21-year-old right wing, scored his first goal on his sixth career shot when hit a wrister from the right circle. Adrian Kempe fed the wide-open Luff for the goal.

"It wasn't a perfect shot but luckily it went in," Luff said. "I thought about it a little bit in the previous games. Tonight it was in my head just don't think about it. I kind of just blocked it out and shot my shot and it went in."

Anze Kopitar added an empty-netter with 30 seconds left.

This was the first meeting this season between the teams. St. Louis won two of three last season and is 6-3-0 in the last nine matchups.

Blues goalie Jake Allen faced 26 shots in falling to 5-3 in his career against the Kings. Allen was pulled with 1:45 to play but the Blues were unable to score.

"You can't win hockey games without scoring goals," Blues defenseman Alex Pietrangelo said. "This has to be a harder place to play."
