Holtby blamed himself for the goal and the loss, as he was dented for four or more goals for the third time in as many starts for just the sixth time in his NHL career.
"I have to make a save on the fourth goal," sways Holtby. "It's as simple as that. I thought we played well in most areas. It just can't happen."
The Caps vied hard for the equalizer in the third, but weren't able to get another puck past Varlamov, despite outshooting the Isles 17-4 in the final frame and out-attempting New York by a whopping 36-10. But Varlamov stopped all 17, and his teammates got in the way of 10 more Washington bids, blocking 27 shots in the game, five more than the Islanders managed to get on net themselves.
"I didn't mind our first two periods; [the Caps] didn't have very many chances," says Isles bench boss Barry Trotz. "The third period, we were on our heels a little bit, but we jammed it up and got some big blocks."
With Tuesday's win, the Islanders head home with a 2-1 mark for a three-game road trip. They also pulled to within six points of Washington in the Metro standings. The Isles have three games in hand, and could make up that difference merely by winning those games in hand.
"It's pretty tough to play 82 games the way you want to play," says Kuznetsov. "Sometimes the games will be like that. We just have to think about the future and focus on the next game.
"Sometimes we're going to get two points when we do not deserve [them], but sometimes we're going to lose when we deserve a point or even more. But it's hockey, right? We just have to think about the future."
