LAS VEGAS — The historically successful start for the expansion Vegas Golden Knights got even more rich Thursday night as they beat the two-time defending Stanley Cup champion Pittsburgh Penguins 2-1. Vegas’ Marc-Andre Fleury made 24 saves against his former team and defenseman Jon Merrill scored the game-winner at 8:17 of the third period for his first goal of the season. The Golden Knights improve to 20-9-2, reaching the 20-win plateau the fastest for an expansion team in NHL history. The sellout crowd included a strong contingent of Penguins fans, who along with the Golden Knights backers gave Fleury a loud round of applause when he was introduced. Fleury played his previous 13 seasons with Pittsburgh before he was taken by Vegas in the expansion draft in June. Murray also made 24 saves for the Penguins, who have lost three consecutive games. Capitals 5, Bruins 3 Alex Chiasson scored two third-period goals — the second short-handed — to help Washington defeat Boston for the 11th straight time. The Capitals’ Braden Holtby stopped 34 shots to raise his career record against the Bruins to 13-2-0. Rookie Jakub Vrana, Nicklas Backstrom and Alex Ovechkin (empty net) also scored for Washington, which has won nine of its last 11 games. Patrice Bergeron scored twice — including a power-play goal 4:22 into the second period to tie the game for Boston, which had its three-game winning streak snapped and lost for only the third time in its last 11 games. Brad Marchand set up Bergeron’s first goal, notching his 400th NHL point and extending his points streak to seven straight games (four goals, seven assists). Lightning 4, Coyotes 1 Nikita Kucherov scored for a third consecutive game and set up one of two goals in a 41-second span of the first period, and league-leading Tampa Bay won its season-high sixth straight game. Kucherov took over the NHL scoring lead by one point (44-43) over teammate Steven Stamkos, who had an assist, and the Lightning improved to an NHL-best 23-6-2 while dropping Arizona to a league-worst 7-22-5. The Coyotes lost their fifth in a row and eighth in nine games. Tyler Johnson and Brayden Point also had a goal and an assist each to support goalie Andrei Vasilevskiy, who excelled again by stopping 32 shots. Vasilevskiy has given up only eight goals while winning his last five starts, and is a league-best 21-4-1. Predators 4, Oilers 0 Juuse Saros stopped 46 shots as Nashville improved to 15-2-2 in its last 19 games despite recording only 23 shots. Pontus Aberg, Kevin Fiala, Kyle Turris and Roman Josi scored in the second period for the Predators. Aberg scored on their first shot of the second period and Nashville’s fifth of the game. Laurent Brossoit made 19 saves in his sixth straight start for Edmonton. It has been a maddening four-game stretch for the Oilers, who scored 13 goals in defeating Montreal’s Carey Price and Columbus’ Sergei Bobrovsky, but were stymied by backups Saros and Toronto’s Curtis McElhinney, who beat them 1-0. Flyers 2, Sabres 1 Valtteri Filppula scored the go-ahead goal late in the second period and Brian Elliott turned aside 19 shots to help Philadelphia win its fifth straight game. Blackhawks 5, Jets 1 Vinnie Hinostroza and Tommy Wingels scored on Chicago’s first two shots as the Blackhawks routed Winnipeg. Patrick Kane, Nick Schmaltz and Michal Kempny also scored for the Blackhawks, who won their fourth straight game. Corey Crawford stopped 27 shots in the Chicago net. Wild 2, Maple Leafs 0 Goals by Tyler Ennis and Mikael Granlund supplemented a 28-save performance by goaltender Alex Stalock as Minnesota defeated Toronto. Ducks 3, Blues 1 Kevin Roy scored a pair of goals and John Gibson stopped 29 shots to lead Anaheim past St. Louis. Blue Jackets 6, Islanders 4 Columbus gave away a three-goal lead but recovered by scoring twice in the second period and holding on to defeat New York. Sharks 3, Flames 2 Joonas Donskoi scored at 17:12 of the third period to lead San Jose over Calgary. Canadiens 2, Devils 1 (OT) Carey Price made 31 saves and Tomas Plekanec scored at 1:52 of overtime as Montreal snapped a three-game losing streak. Avalanche 2, Panthers 1 Nathan MacKinnon had two goals and Semyon Varlamov made 32 saves as Colorado defeated Florida. — Reuters
