PHILADELPHIA -- Nick Leddy scored at 2:44 of overtime to give the New York Islanders a 5-4 win against the Philadelphia Flyers at Wells Fargo Center on Friday.
Joshua Ho-Sang took the puck behind the net before skating back in front and feeding Leddy in the slot. Leddy's wrist shot beat Brian Elliott to give New York (13-7-2) its fifth win in six games.

"[Ho-Sang] made a great play at the end and I just tried to put it back far side," Leddy said.
Philadelphia (8-9-6) blew a two-goal lead in the third period and lost its seventh straight game (0-3-4). It's the Flyers' longest losing streak since going 0-8-2 from Feb. 6-23, 2008.
"We have to find a way to get confidence, especially in the third," Flyers captain Claude Giroux said. "We have to believe in what we're doing and what we're doing is going to work.
"When we start believing that we're a good team and we can finish games and the way we play is going to win us games, we're going to start winning. Until then, stuff like this can happen."
Jordan Eberle began the comeback for New York when he scored on the power play at 4:12 of the third period to make it 4-3. Andrew Ladd tied it at 12:11 when he jammed home Eberle's feed from behind the net.

"I didn't say a word between the second and third (periods)," Islanders coach Doug Weight said. "Generally, that's when you're mad. But I think they felt at the end of the second that they were going to win the game."
Mathew Barzal had a goal and an assist, and Cal Clutterbuck also scored for the Islanders, who completed a home-and-home sweep of the Flyers. New York defeated Philadelphia 4-3 in overtime at Barclays Center on Wednesday.
Scott Mayfield had two assists and Thomas Greiss made 12 of his 26 saves in the third period, including knocking away Jakub Voracek's shot in the final seconds.
"Finding a way to get the game tied and get it into overtime and then get two points out of the game is pretty huge for us," Ladd said.
Shayne Gostisbehere and Sean Couturier scored 19 seconds apart in the second period to give the Flyers a 4-2 lead. Gostisbehere and Couturier also had one assist each.

Giroux had a goal and an assist, Wayne Simmonds scored and Voracek had two assists for the Flyers. Elliott made 32 saves.
Philadelphia has blown two-goal leads in three of its past five games.
"Seven of our last 10 that we've gotten a point," Flyers coach Dave Hakstol said. "So five of those are OT or shootout losses. Again today, a close hockey game all the way through, and we have to find a way to finish the games in overtime."
Philadelphia used a four-goal second period to take the lead. Gostisbehere scored on a delayed penalty at 12:11 to make it 3-2. Couturier chipped a shot over Greiss on a feed from Voracek at 12:30 to make it 4-2.
Giroux scored on a slap shot between the circles at 3:49 to tie it 1-1, and Wayne Simmonds ended a 14-game goal drought when he knocked in Gostisbehere's shot off the post at 6:28 to make it 2-1.
Clutterbuck deflected in Dennis Seidenberg's shot at 7:56 of the second period to make it 2-2.

Barzal extended his point streak to five games when he poked in a bouncing puck with 16.9 seconds left in the first period to give the Islanders a 1-0 lead.

They said it
"It's huge. It's a couple extra points that they don't get, and every game is so tight within the (Metropolitan) Division. You look at all the teams and they're all so close, so every point is huge." -- Islanders defenseman Nick Leddy
"Right now, it's a tough time. There's still growth going on during this time and that always doesn't come easy. We've got to be up to that challenge, mentally, physically, to come back and do a little bit better." -- Flyers coach Dave Hakstol
