Marc-Andre Fleury stopped 26 shots for his first shutout with Vegas, William Karlsson scored during a three-goal first period and the Golden Knights beat the Washington Capitals 3-0 on Saturday night.

Fleury was perfect in his 699th career game and eighth since being selected by Vegas in the expansion draft.

Alex Tuch and Oscar Lindberg also scored in the first period for Vegas, which went 4-0-1 on this homestand and has a point in nine straight games.

Washington was 4-0-1 in its past five games and 8-1-1 in its last 10, but the Capitals lost their second in two nights, including a defeat to the Coyotes.

The Capitals had scored at least four goals in six of their previous nine games and hadn’t been shut out since a 2-0 home loss to Toronto on Oct. 17 — the only other time they’ve been blanked this season.

Tuch opened the scoring by tapping in Brendan Leipsic’s rebound for his eighth of the season. Lindberg then took a pass from Tomas Nosek and punched in his seventh. AP
