Islanders coach Jack Capuano has said there’s no time for waiting in these playoffs, and he made that crystal clear with some significant lineup changes.

For last night’s 4-3 win over the Penguins at Consol Energy Center, which tied the teams’ first-round playoff series 1-1, Capuano’s most drastic move was juggling his top two lines. For the first time since he joined the team in 2009, Matt Moulson was no longer on the left of John Tavares, but on a second line with Frans Nielsen and Kyle Okposo. Josh Bailey took Moulson’s regular spot next to Tavares and Brad Boyes.

“It’s something that we’ve been thinking about for a while,” Capuano said. “Sometimes it’s funny how things work [after] a little tweak. I thought they played well.”

Moulson scored a power-play goal 7:04 into the first period that cut the Penguins’ lead to 2-1, and got the first assist on Okposo’s game-winner with 7:37 to play.

Tavares was held mostly in check by the Pens again, but did have a team-high six shots after having none in Wednesday’s 5-0 Game 1 defeat.

“We felt our game was getting better and better as the game went on,” Tavares said. “We felt real comfortable. We felt like we got the lead and we were going to do what we needed to to hold on.”
