EDMONTON -- Jonathan Marchessault had two goals and an assist for the Vegas Golden Knights in a 6-3 win against Edmonton Oilers at Rogers Place on Sunday.
Reilly Smith had a goal and two assists and defenseman Colin Miller had three assists for Vegas (9-11-1). Marc-Andre Fleury made 29 saves.
"My past 10 games were not good and neither was my last game (a 4-1 loss against the St. Louis Blues on Friday), so I definitely needed to pick it up," Marchessault said. "Everyone is important on our team and we need to do what we do best to be successful and that's what we did tonight, I think."

Leon Draisaitl had a goal and assist for Edmonton (9-10-1), which has lost two straight and six of its past seven games (1-6-0). Forward Drake Caggiula had two assists and Cam Talbot made 25 saves.
"We had a couple of breakdowns that shouldn't happen at this point in the season," Draisaitl said. "It seems like every time we get scored on, we change our game or something. That is something we have to work on, stop doing and get better at."

Connor McDavid scored 52 seconds into the game to give the Oilers a 1-0 lead, tipping in a point shot from defenseman Matt Benning.
Golden Knights center William Karlsson scored at 12:57 to tie it 1-1, redirecting defenseman Shea Theodore's point shot over Talbot's shoulder.
Oilers forward Alex Chiasson scored on the power play at 16:33 of the first period when he lifted a rebound over Fleury to give Edmonton a 2-1 lead.
"We weren't very happy with our first period and then we made some really good adjustments inside the dressing room with players taking control of the situation and making sure everybody was contributing," Golden Knights assistant coach Ryan McGill said. "I think in the last 40 minutes, everybody did contribute."
The Golden Knights tied it when forward Cody Eakin scored shorthanded at 2:21 of the second period. Eakin collected a loose puck at center ice, skated into the Oilers zone and snapped a shot over Talbot's blocker.
"There was a turnover and then a bad pass and I was able to get the puck and it was a 2-on-1 and I shot through a screen," Eakin said. "It was a good way to tie it up. We came out strong in the second, one thing led to another and we had a few in the back of the net. That's what we needed."
Golden Knights forward Max Pacioretty made it 3-2 at 3:53 when his centering pass banked in off Benning's skate.
Marchessault extended the lead to 4-2 with a power-play goal at 4:33. He scored again 34 seconds into the third period off a pass from Miller.
"We did a lot wrong," Oilers coach Todd McLellan said of Eakin's shorthanded goal. "We were sloppy breaking out, we fell behind the net, we turned it over from there, put it in the feet of one of our players, didn't challenge the rush and didn't get the save, so that's five mistakes in about 10 seconds of play.
"Unacceptable. That changed the momentum and I think triggered a five or six-shot barrage where four of them went in, and it's tough to recover from that."
Smith gave the Golden Knights a 6-2 lead at 3:04 of the third before Draisaitl scored at 3:44 for the 6-3 final score.
Golden Knights defenseman Nate Schmidt returned from a 20-game suspension for violating the NHL/NHLPA Performance Enhancing Substances Program and was plus-1 in 19:38 of ice time.
"It was just fun to be back," Schmidt said. "I thought we skated really well in this game and I haven't been here in the last little while, but I felt like our room was good between periods."

"The two in a row in the second, we got a little momentum and then after that we were able to get pucks in deep and we were able to play below their goal line a lot. That was nice. The two quick ones changed the momentum a bit." -- Golden Knights forward Cody Eakin

"We have to focus on playing a consistent 60 minutes. We have stretches where we dominate games and teams can't even get in our zone and then we have stretches where we can't even get out of our own zone." -- Oilers center Connor McDavid
