LAS VEGAS _ The New York Islanders lost a game they absolutely deserved to lose on Thursday night.
The Vegas Golden Knights controlled play for all but the final 1:30 of the first period and rallied from a two-goal deficit to snap the Islanders' three-game winning streak with a 4-2 victory at T-Mobile Arena.
"The last 40 minutes, we were all kind of fighting the puck a little bit, trying to fight the game," captain Anders Lee said. "We're pretty frustrated, to be honest."
An under-siege Thomas Greiss made 43 saves for the Islanders (17-13-4), who conclude this four-game road trip Sunday night at Dallas. Marc-Andre Fleury needed to make just 19 saves for Vegas.
"I'd say we weren't committed as we were in the first period," Islanders coach Barry Trotz said. "Our bench wasn't as focused as it needed to be. That's on me and the group. I've got to settle it down."
The Golden Knights (20-15-2), who have won six straight at home, finally took control on the scoreboard in the third period as William Karlsson, on a four-on-four goal, tied the score at 2 at 6:22. Paul Stastny made it 3-2 at 7:25.
Oscar Lindberg caught Islanders defenseman Johnny Boychuk with an illegal check to the head _ Boychuk missed time as he cleared concussion protocol in the third period _ but it became a four-on-four at 5:21 as Anthony Beauvillier confronted Lindberg. Nate Schmidt's empty-netter clinched it.
