ST. LOUIS -- Oskar Sundqvist had his first multigoal game in the NHL for the St. Louis Blues in a 5-3 win against the Vegas Golden Knights at Enterprise Center on Thursday.
Sundqvist scored twice, Tyler Bozak had a goal and an assist, and Robert Thomas had two assists for St. Louis (4-4-3), which has won two straight and is 3-1-1 in its past five. Jake Allen made 31 saves.
"That's the thing that we've seen in training camp," Blues coach Mike Yeo said of Sundqvist. "Last year, we knew every single game that he was going to be good defensively and be reliable. You can match him up against anybody. You could put him on the ice and feel confident that you weren't going to be scored on. This year in training camp, what we've seen is there's more offense to his game."

Alex Tuch had a goal and an assist, and Marc-Andre Fleury made 21 saves for Vegas (5-7-1), which has lost four of its past five games.
"We had some good moments tonight, then again we end up losing the hockey game, but it's a group thing," Golden Knights coach Gerard Gallant said. "It's the whole group and that's the way we are as a team, and we win as a team, we lose as a team, and we've got to get better. Everybody's got to get better."

Sundqvist, who entered the game with two goals in 72 NHL games, gave the Blues a 3-2 lead at 6:29 of the second period, beating Fleury above his shoulder from the left circle.
"I actually thought it was going to hit the (Golden Knights defenseman Deryk Engelland)," Sundqvist said. "I was happy that it went in."
Colton Parayko extended the lead to 4-2 at 14:49 with a one-timer from the left circle.
Tuch cut it to 4-3 at 8:02 of the third period with a power-play goal, but Bozak beat Fleury glove side from the left hash marks to make it 5-3 at 11:47.
"I think [Joel Edmundson] made a great play," Bozak said. "If it was a pass or shot, either way, he got it past the guy to the net towards me, so it was a great play by him. The goalie kind of went down thinking it was a shot, so I had quite a bit to shoot at."
Sundqvist gave the Blues a 1-0 lead at 2:02 of the first period, holding off Golden Knights defenseman Brayden McNabb and scoring into an open net. Pierre-Edouard Bellemare tied it 1-1 at 6:29.
Vladimir Tarasenko scored a power-play goal to make it 2-1 at 3:11 of the second period, but Erik Haula scored 23 seconds later to tie it 2-2.
Blues forward Robby Fabbri had an assist in his first NHL game since Feb. 4, 2017. He was medically cleared this offseason following his second ACL surgery.
"I felt like I wasn't nervous," Fabbri said. "I felt like I was able to play my game and I think those three games in San Antonio (of the American Hockey League) helped with my legs and get my legs underneath me and it felt good tonight.
"It was exciting. It was exciting for me and my family. They were all together watching tonight. It's just great to get back in the lineup with the guys. It makes it even more special. We got a big win tonight."

"It was not a complete game. We have times of the game where we play the right way and other times where we don't, and it ended up costing us big time. We're going to have to figure out to play a full 60 minutes because 40 is nowhere near close enough." -- Golden Knights center Pierre-Edouard Bellemare

"I was glad to be back for this game. I was close to not playing, but I was glad to be back and be with the guys. It was a big win for us. Try to get some momentum here." -- Blues goalie Jake Allen, who left St. Louis' game against the Chicago Blackhawks last Saturday in the second period following a collision
