Islanders 2, Panthers 1 (2OT)

Alan Quine was a newborn when the New York Islanders last won a playoff series. He spent most of this season in the minors. His NHL debut was a mere two weeks ago, the team adding him to the roster as an emergency callup.

And now he's a playoff hero.

The 23-year-old Quine put the Islanders in position to end a 23-year drought between playoff series wins. His slap shot at 16 minutes of the second overtime — 96 minutes into the game — narrowly beat Florida goalie Roberto Luongo, and New York topped the Panthers 2-1 in Game 5 of their Eastern Conference quarterfinal series.

The game started Friday, ended Saturday at 12:16 a.m., and the Islanders — now up 3-2 in the series — will try for the clincher in Brooklyn on Sunday.

"Right in my wheelhouse," Quine said of the power-play winner, "and I just ripped it."

Thomas Greiss' spectacular series continued, stopping 47 shots for the Islanders. He's saved 92 of the last 95 shots he's faced.

"I think we're playing great hockey," Panthers coach Gerard Gallant said. "We're getting great scoring chances. The kid's playing really well. ... Hopefully, sooner or later, we're going to get some breaks."

Luongo made 40 saves for Florida, which missed a penalty shot in the first overtime, then was whistled for two penalties in the second overtime.

The Isles' second OT power play came when Derek Mackenzie was called for slashing at 14:31, and Florida succumbed. Quine took a pass out of the high slot from Marek Zidlicky — who didn't play in any of the series' first four games — and fired a blast from the right side that beat Luongo.

The Islanders swarmed the ice in celebration. Luongo fell onto his back, and Gallant's frustration with the call was evident.

"Definitely disappointing," Gallant said. "But what do you do? They call penalties and penalties are part of the game. Make a great shot, they score the winning goal. It was a great hockey game."

Frans Nielsen scored in the first period for the Islanders. Aleksander Barkov tied it early in the third for the Panthers, and had a chance for an NHL first — an overtime penalty shot goal.

The Islanders' Calvin De Haan closed his hand on the puck in the crease 7:19 into the first overtime and Barkov was awarded the third OT penalty shot in league history as a result. And like the other two, it missed.

Barkov's backhander was handled by Greiss, and play continued.

Said Barkov: "The goalie made a great save."

Said Greiss: "I'm lucky I got it."

It was the second overtime game of the series, the other New York's home win in Game 3. Exclude Florida's empty-net goal that sealed Game 2, and all five games of this matchup between 100-plus-point regular-season clubs has been of the one-goal variety.

"We'll be ready for Sunday," Panthers defenseman Brian Campbell said.

Florida tied it 1:59 into the third. Jonathan Huberdeau got knocked down in the left circle but Jaromir Jagr retrieved the puck, played it back toward the right point, and Barkov scored off Alex Petrovic's pass to knot the game at 1-1.

Nielsen put New York on top with 6:29 left in the opening period, putting home the rebound of a shot by Thomas Hickey.

About four hours later, Quine entered Islanders' lore.

"We got the bounce on the power play," Islanders coach Jack Capuano said, "from a guy that was in the American Hockey League a month ago."

Sharks 6, Kings 3

The Sharks had just blown a three-goal lead in a potential series-clinching playoff game. Staples Center rocked with the combined power of the Kings' rally and the looming specters of San Jose's postseason failures.

Joonas Donskoi wasn't around for any of that tawdry teal history, and the tenacious rookie scored the goal that sent the Sharks roaring into the second round.

Donskoi broke a tie with his second goal early in the third period, and the Sharks charged back to wrap up their first-round playoff series with a victory over Los Angeles in Game 5.

Chris Tierney and Matt Nieto scored early goals and Joe Pavelski got another late score for the Sharks, who stared down the ghosts of their past playoff failures against Los Angeles and advanced to the second round for just the second time since 2011.

The Sharks had to overcome more than the current Kings, who looked outclassed for most of the series. San Jose has an unpleasant history against its downstate rivals, who rallied from an 0-3 series deficit to eliminate the Sharks in humiliating fashion in 2014.

"I'm sure for some guys, they felt like we exorcized some demons tonight," said San Jose coach Peter DeBoer, also a rookie in teal. "For the group in general, it was a well-earned victory. To win three games in this building is a great testament to the character of our group."

The Sharks didn't do it easily. San Jose led 3-0 early in the second period of Game 5 before the Kings scored three goals in nine electric minutes.

But after Donskoi jumped on a rebound and broke the tie with the second playoff goal of his rookie season with 16:02 to play, Pavelski added his fifth goal of the series and the Sharks cruised.

"Of course we were disappointed with what happened in the second period," said Donskoi, the 24-year-old Finn. "We tried to forget that. The game was still tied, and we had a chance to beat LA."

Anze Kopitar, Jeff Carter and Kris Versteeg scored for the Kings, who won only Game 3 in overtime in this series after eliminating the Sharks in 2013 and 2014. Their run at a third Stanley Cup title in five years ended abruptly, with losses in all three of their home playoff games.

And the Sharks left little doubt that this California rivalry is heated after four postseason series meetings in six years.

"Throughout the last couple of years, things have been said by players on that team that to me, personally, I take it as disrespectful," said Logan Couture, who had three assists. "So it was nice to stick it back to them and beat them in this series. Even this series, someone was saying on their team that they had us right where they wanted us. I wonder if they've got us where they want us right now? So it was nice to beat them."

Martin Jones made 19 saves, Brent Burns had three assists and Melker Karlsson added an empty-net goal for the Sharks, who will next face the winner of the Anaheim Ducks' series with the Nashville Predators. The clubs are even heading to Game 5 in Anaheim on Saturday.

Jonathan Quick stopped 22 shots while losing to his former backup again.

The loss was a disheartening finish for the playoff-tested Kings, who won two titles and 10 postseason series from 2012-14. After missing the playoffs entirely last spring, Los Angeles returned with renewed energy and reigned atop the Pacific Division for most of this season, but blew the division title in its final home game before getting bounced by the Sharks.

"It's definitely disappointing (after) how hard we worked in the season to clinch a (playoff) spot as fast as we could, that we didn't make the most of it," said Milan Lucic, a free agent this summer. "We can make excuses all we want ... but we didn't play the right way when we needed to"

Nieto made it 3-0 early in the second period for San Jose. The lead could have been even bigger, but the Sharks failed to score during a 5-on-3 advantage for 1:45, and Patrick Marleau couldn't score on a penalty shot.

The Kings finally awoke when Drew Doughty's shot ricocheted off Dwight King and Kopitar midway through the second. Carter got his second goal of the series a few minutes later, and Versteeg tied it with his first playoff goal for his new team, batting home a rebound of Kyle Clifford's shot off the post.

"We didn't deserve to win this series," Kopitar said.

Wild 5, Stars 4 (OT)

Mikko Koivu and Minnesota are going home and hoping for another trip to Dallas.

Koivu scored the tying goal with 3:09 left in regulation, then redirected Ryan Suter's shot from the left point 4:55 in the overtime as Minnesota beat the Stars to stay alive in their first-round series.

"We felt confident, we thought we were going to come out and play a good game. Games 2, 3, 4 and 5, I've liked," Wild interim coach John Torchetti said. "Now we got to go home and try and find a way to get back to Dallas."

Dallas, the top seed in the Western Conference, still has a 3-2 lead in the best-of-seven series. Game 6 is Sunday in Minnesota.

If the Wild can force a Game 7, that would be Tuesday night back in Dallas.

Jason Spezza and Alex Goligoski scored 28 seconds apart almost midway through the third period, giving the Stars their first lead of the game.

"We still knew there was a lot of time left. I thought we played a good hockey game. That momentum can switch real quick and it did," Koivu said. "But I thought we stuck with it."

The Wild forced overtime when Koivu went top shelf for the tying goal. Koivu, the Wild's leading scorer in the regular season with 56 points, had only one goal without an assist in the series until then.

Asked what the game meant to Koivu, his coach responded, "Well, I think that he really wanted it, that's for sure. I don't know all the stat stuff and all that, I just know that his leadership, that's what it's all about."

Dallas fell behind 2-0 in the first 5 1/2 minutes and didn't lead until Goligoski's goal with 11:04 left in regulation that hit the back of defenseman Marco Scandella on the way into the net and made it 4-3.

That came right after Spezza's third goal of the series. With a defender tugging along, Spezza sent a shot that slid in front of Devan Dubnyk and hit the far post before ricocheting past the line to tie it.

Dubnyk stopped 37 shots.

Antti Niemi stopped 19 of 24 shots in his second consecutive start in the series for Dallas after Kari Lehtonen was in goal for the first three games.

"Tough goals, most of them. Hard stops," Niemi said. "Obviously, you don't want to give up five."

After a scoreless, sometimes lethargic second period, the third period started with Minnesota up 2-1. The teams then almost immediately traded goals in a span of 50 seconds.

Stars captain Jamie Benn tied it at 2 with some nifty stick work, guiding the puck around Dubnyk and into the net only a minute into the third period.

The Wild didn't stay down long, with Nino Niederreiter scoring to put them back up.

"They came out pretty high and kind of back and forth in the third there," Benn said. "It's just a tough one to lose. ... You score four, you should probably win the hockey game. But it's just one of those games where it was back and forth. And I think we can clean it up a bit in the defensive zone."

Like he has all season, Stars coach Lindy Ruff has gone with both goalies in the playoffs.

Lehtonen was in net when the Stars won the first two games at home, and for the 5-3 loss in Game 3 at Minnesota. Niemi then stopped 28 shots in their 3-2 win in Game 4, but gave up two goals in less than 5 1/2 minutes Friday night.

The Wild took advantage when Goligoski turned over the puck right in front of Niemi. Mikael Granlund initial's shot was stopped but the loose puck was to the left of the net, and Granlund poked it in with David Jones getting an assist after getting his stick in the fray.

Less than 2 minutes later, Jordon Schroeder, playing his first game in the series, scored on a pass from Ryan Suter.

Johnny Oduya scored his first goal for Dallas since Dec. 17 — a span of 55 games, including the playoffs — to get the Stars to 2-1 before the first intermission with his one-timer from above the left circle.

Flyers 2, Capitals 0

Standing in the same crease that Steve Mason allowed a goal from 101 feet out, Philadelphia goalie Michal Neuvirth saw shots from every angle and didn't crack. Not even once.

Neuvirth stopped all 44 shots Washington threw his way, carrying the Flyers to a victory and sending the first-round playoff series back to Philadelphia for Game 6 on Sunday.

"They came at us pretty hard and if it's not for Neuvy, we're not winning this game," Flyers captain Claude Giroux said.

After the Capitals took a 3-0 series lead, Neuvirth has been the difference since replacing Mason for Game 4 on Wednesday. Neuvirth has stopped 75 of 76 shots against the team that drafted and developed him after Mason allowed 12 goals on 81 shots.

It didn't matter that Washington outshot Philadelphia 44-11 and an almost unbelievable 35-6 at 5-on-5. It's the first time a team won a Stanley Cup playoff game with 11 shots since the Capitals beat the Ottawa Senators in 1998, and that total is the fewest shots in Flyers history counting the regular season and playoffs.

Neuvirth said he got used to heavy shot totals by playing with the lowly Buffalo Sabres last season, though this tied the second-biggest disparity by a losing playoff team since 1989-90, according to STATS.

"I like to face a lot of shots. It keeps me in the game," said Neuvirth, who set a franchise records for saves in a playoff shutout and saves in a regulation playoff game. "I enjoy it. Guys did a really good job in front of me. I was seeing the puck well. We didn't take any bad penalties, and we stuck to our system and big win for us."

It's the biggest win yet for the Flyers, who are still feeling the emotions of the death of founder Ed Snider, whose public memorial service they attended Thursday before travelling to Washington. Yet they were not at their sharpest in Game 5, which Giroux called the Capitals' "best game of the series."

The Flyers went 0 for 6 on the power play to fall to 1 for 21 in the series. Ryan White scored three seconds after a penalty expired as the puck bounced off Capitals defenseman Taylor Chorney's left skate and past Braden Holtby 7:52 into the second period.

"To get it by that guy, they're not going to be pretty on him," White said about Holtby, who made nine saves. "Doesn't matter how they go in."

It matters to the Capitals, who lost back-to-back games in regulation after not doing so the entire regular season on the way to the Presidents' Trophy. They chalked the loss up almost entirely to Neuvirth, who stopped eight shots from superstar Alex Ovechkin and five each from defensemen John Carlson and Karl Alzner.

"We have lots of perimeter shots, but we don't have traffic in front of the net," Ovechkin said. "You see all these shots that he makes, he sees everything."

Washington coach Barry Trotz pointed to the 82 shot attempts as an indication of his team's dominant play. There's no arguing the Capitals were the better team.

"We had a couple good looks and we didn't finish them," Trotz said. "They got a little bit of a lucky goal. You put the puck to the net, sometimes, it goes in. It did. I went off, I think it was Chorney's toe and went in, and it was really a nothing play. If we play like that, next game, we should be fine."

Game 6 is noon Sunday at Wells Fargo Center. Even the thought of a Game 6 earlier in the week would have been unfathomable, but thanks to Neuvirth it's a reality.

"Neuvy stole us a game," Flyers forward Sam Gagner said. "He's made a lot of big, timely saves for us and kept us alive."

Relying on Neuvirth to withstand onslaught after onslaught is not the Flyers' plan moving forward, but there is some history to that in Washington. A handful of Capitals players need only think back to 2010 when Jaroslav Halak stopped 217 of 231 shots and the Montreal Canadiens erased a 3-1 series deficit to pull off the upset.

That same year, the Flyers erased a 3-0 deficit to beat the Boston Bruins.
