OTTAWA, Ontario — Maxime Lagace was relieved to pick up his first NHL victory after allowing 11 goals in his first three appearances. The 24-year-old goalie made 24 saves for the Golden Knights in a 5-4 victory over the Senators on Saturday. "It's good to have the first one finally," Lagace said. "The guys played really well, so I have them to thank for that win." The game was all the more special with Lagace's parents and other family members in attendance. "It's a really special moment, and I'm pretty excited," Lagace said. "I got nervous a little bit, but not nervous to the point where it could affect my game."Expansion Vegas snapped a three game-losing streak to improve to 9-4-0. "They are the hardest-working team in the league," Ottawa coach Guy Boucher said of the Golden Knights. "That's how they win. They're relentless. They have four lines of guys who work hard, and if you don't have four lines and six D that are working as hard, then sooner or later they're going to hurt you." Erik Haula had two goals and an assist for Vegas. Alex Tuch, William Karlsson and Jonathan Marchessault also scored, and Marchessault, a former Lightning forward, added two assists. "They didn't surprise us," said Senators captain Erik Karlsson, who had a goal. "They played a well-structured game and did the things they needed to do to be successful. We couldn't find a way to break their pattern and find our own way to be successful for long enough." Mark Stone, Alex Burrows and Ryan Dzingel also scored for Ottawa, and Craig Anderson stopped 29 shots. The Senators leave Monday for Sweden for two games against the Avalanche. Marchessault gave Vegas a 3-2 lead on a power player with 7:21 left in the second. William Karlsson scored on a wraparound to make it 4-2 at 3:29 of the third, and Haula had a power-play goal at 6:47. Dzingel's fifth of the season for Ottawa made it 5-3 at 7:52, and Erik Karlsson scored his first of the season in the final minute of play.
