Playing with a decidedly shorthanded lineup and with some new faces for the third straight game, the Caps came out with a great deal of verve in the first. They played quick and spent a good deal of time in the New York end of the ice. Better still, they maintained that jump throughout most of the 60 minutes.
The offensive-zone time paid off when Sprong drew a tripping call on Matt Martin at 10:12 of the opening period, giving the Caps the first man advantage of the evening. Just under a minute later, Washington grabbed the lead.
From center point, Justin Schultz took a Nicklas Backstrom feed and put a shot on net. Varlamov made the stop but lost track of the rebound. John Carlson found it first and buried it, giving the Caps a 1-0 lead at 11:06 of the first.
New York struck back before the end of the first, drawing even when a Noah Dobson right point shot glanced off Dillon's toe cap and went in at 15:33 to make it a 1-1 game.
Early in the second, Backstrom caught a puck up high and immediately went off for repairs. He returned and skated half a dozen shifts in both the second and third periods, but wasn't on the bench at game's end, and didn't play in the final 4:22 of the contest.
Midway through the second period, New York's Mathew Barzal gave the Isles their only lead of the night. Zdeno Chara's pass from behind the Washington net went straight Barzal's tape, and the Isles pivot put a backhander behind Vitek Vanecek at 10:01 to make it a 2-1 game.
Washington has yet to trail at the end of any period this season, and Sprong's first goal as a Capital came off the rush late in the second, keeping that streak alive. Playing his first game as a Capital, Carr gained the New York line on the left side and fed Sprong on the middle of the ice. From the high slot and out of a cluster of players from both sides, Sprong let it rip, beating Varlamov high to the blocker side with 2:39 left in the frame.
