LAS VEGAS -- The Vegas Golden Knights clinched the Pacific Division in their inaugural season after defeating the San Jose Sharks 3-2 at T-Mobile Arena on Saturday.
Vegas is the third team this season to win 50 games (50-22-7) and is guaranteed home-ice advantage for the first two rounds of the Stanley Cup Playoffs.
"It's great. It's a great feeling to win our division," Golden Knights coach Gerard Gallant said. "Obviously, nobody had those expectations at the beginning of the season, but as we know, our team grew on everybody. We've worked hard all season long, but we all know what the real accomplishment is supposed to be. It's all about the playoffs."

The Golden Knights became the first modern-era expansion team from any of the four North American professional sports leagues to start from scratch and finish first in its division (excluding mergers and all-expansion divisions), according to the Elias Sports Bureau.
William Karlsson scored the go-ahead goal shorthanded at 8:35 of the third period, his 42nd of the season, tying him with Pittsburgh Penguins forward Evgeni Malkin for third in the NHL. Shea Theodore and Oscar Lindberg also scored for Vegas, which is four points behind the Nashville Predators for first place in the Western Conference. Nashville has one game in hand.
Marc-Andre Fleury made 29 saves for his 403rd NHL win, moving him into 11th place on the League's all-time list.
Karlsson's highlight-reel goal gave Vegas a 3-2 lead when he skated in alone, put the puck between his skates and roofed a shot over Martin Jones.
"I don't really look at it that way," Karlsson said on his goal clinching the division. "It was more of getting the two points. To do it on a special night like this, it's good timing.
"I was more focused on me, putting myself in a great position. [Jones] pulled, luckily, so he kind of let his guard down on the short side and gave me room to shoot."

Joe Pavelski and Marc-Edouard Vlasic scored for the Sharks (44-25-10), who needed a win to clinch a playoff berth. San Jose holds a four-point lead on the Los Angeles Kings for second place in the Pacific.
"The good news is we've set ourselves up to finish this season off with three home games and an opportunity to clinch home-ice advantage, which is something that's been a goal of ours from Day One," Sharks coach Peter DeBoer said. "So, we'll sweep this one under the rug and get ready for the next one."
Theodore scored at 2:21 of the first period to give the Golden Knights a 1-0 lead.
Pavelski tied it 1-1 at 7:14 of the first period.
Lindberg scored for the first time since Dec. 23, his third game back from an undisclosed injury, at 3:03 of the second period to give Vegas a 2-1 lead.
San Jose tied it 2-2 at 9:50 of the second, when Vlasic scored.
"Just not a good enough game to win," DeBoer said. "If you're going to come in here and win at this rink this time of year, you're going to have to bring your 'A-plus' game, and I thought we played a 'B' game. We probably got what we deserved."
Jones made 35 saves.
"The fans deserve it," Golden Knights forward Alex Tuch said. "They've been unbelievable all year. They've supported us no matter what the outcome is. It's been really fun to play in front of them, and I wouldn't want to do it any other way."
