BUFFALO — This four-game road trip, which started with promise in California against two of the NHL’s weaker clubs, stalled once the Islanders started playing tougher competition. And it ended with a dud.

“We were flat tonight,” coach Patrick Roy said. “We didn’t play a good game.”

The Sabres, dominating in every way, sent the Islanders home with a 4-0 defeat on Thursday night at KeyBank Center. They’ve been shut out in back-toback games and have not scored a goal in 121:48.

The Islanders’ inability to connect on passes kept them from generating dangerous chances.

“If we want to be successful, we need to be connected,” Jean-Gabriel Pageau told Newsday. “We need the execution. We’re still in a good position. We need to get the job done, and for that to happen, we just need to execute and be better.”

The Islanders (29-22-14), who went 0-for-4 on the power play, ended the trip a disappointing 2-2-0 after opening with a 7-2 win over the hapless Sharks and a 6-1 victory over the slightly better Ducks. But Monday’s 3-0 loss to the playoff-bound Kings snapped the Islanders’ winning streak at a season-high six games.

Still, the Islanders retained the Eastern Conference’s second wild-card spot as the Red Wings — who have the same 72 points but have played one extra game — lost their seventh straight, falling to the visiting Coyotes, 4-1. The Islanders remained four points behind the third-place Flyers — who have played two extra games — in the Metropolitan Division after they lost to the visiting Maple Leafs, 6-2.

“It’s OK, two of four,” Roy said of the road trip. “Three of four would have been a great road trip. That’s the beauty of this league; it makes you humble pretty fast. You’re flying high, six in a row, you think you’re under control and boom, you lost two and now you’ve got to regroup.”

The Islanders will face the Senators, next-to-last in the conference, on Saturday afternoon at UBS Arena.

“Tonight we just weren’t as crisp as we needed to be,” Anders Lee said. “It just wasn’t a good game by us at all tonight. Let’s get home, let’s regroup a little bit.”

Ilya Sorokin made 33 saves and Ukko-Pekka Luukkonen stopped 21 shots for the Sabres (32-30-5), facing only 11 through the first two periods.

The Sabres, who swept their three-game homestand and moved within three points of a playoff spot, took control with a three-goal second period.

Victor Olofsson’s power-play one-timer from below the right circle with Lee off for interference opened the scoring at 4:28 of the second period.

Dylan Cozens, left wide open low in the slot to knock in the rebound of defenseman Connor Clifton’s initial shot, made it 2-0 at 8:15.

Zach Benson deflected defenseman Henri Jokiharju’s shot from the blue line to give the Sabres a three-goal edge at 9:41, with the goal surviving a challenge from Roy for goalie interference.

Benson added an empty-netter at 15:06 of the third period.

The Sabres also played a dominant first period, kept from taking the lead only by Sorokin’s early brilliance.

The Islanders did not get their first shot until defenseman Adam Pelech sent a wrister on Luukkonen from the blue line at 10:12. Sorokin made a stretching glove save on Peyton Krebs’ shot off an odd-man rush at 14:13 and also stopped Jordan Greenway on an odd-man rush at 17:39 after defenseman Noah Dobson whiffed on the puck at the right point in the Sabres’ zone.

The Islanders generated five power-play shots in 7:39 of man-advantage time. “I feel like we may be complicating things a little too much,” Roy said. “That was the message by Mac [assistant coach John MacLean] before the game. Have things simple and just move that puck quick. But tonight, for some reason, our legs were not there, our execution was not there.”
