PHILADELPHIA -- The Anaheim Ducks had a good road trip, but rookie forward William Karlsson will remember it for a long time.
In his third NHL game, Karlsson scored the deciding goal in the fourth round of the shootout to lift the Ducks to a 4-3 win against the Philadelphia Flyers on Tuesday.
Karlsson started down the right side of the ice, cut toward the middle and snapped a wrist shot from the hash marks that beat Flyers goalie Steve Mason past his glove.
"You just have to smile about the situation," Karlsson said. "You've got to think you're going to be the hero. You can't go out there and think, ‘What if I miss it?’ You have to stay positive."
Karlsson’s shootout-deciding goal Tuesday came one day after he scored his first two NHL goals, including the game-winner, in the Ducks' 5-1 defeat of the Buffalo Sabres.
"I can't complain," Karlsson said. "Hopefully I can just keep it going."
Jakob Silfverberg also scored for the Ducks in the shootout, and goaltender Frederik Andersen stopped three of four Flyers shooters, in addition to making 39 saves in regulation and overtime in his third straight start.
Tim Jackman, Devante Smith-Pelly and Matt Beleskey scored in regulation for the Ducks.
Anaheim returns home with wins in the final three games of its season-opening four-game road trip. After losing to the Pittsburgh Penguins to open the season, the Ducks defeated the Detroit Red Wings, Sabres and Flyers in a four-day span.
"To win the last three on the road was something that we thought we didn't know if we could do, but it was a great goal to have, and we did it," Ducks coach Bruce Boudreau said.
Claude Giroux scored the Flyers' only goal in the shootout. It's the second straight shootout loss for the Flyers; they lost 4-3 to the Montreal Canadiens in the tiebreaker Saturday.
The Flyers have lost seven straight shootouts; their last win in the tiebreaker was Dec. 30, 2013, at the Vancouver Canucks. The Flyers' 27 shootout wins are the second-fewest since the League adopted the shootout in 2005.
"They're big points," Giroux said. "Maybe they don't look like it right now, but the end of the season those two points are going to be crucial probably. We just have to make sure next time we get it done."
Wayne Simmonds had a goal and an assist, and Mark Streit and Jakub Voracek had goals for Philadelphia. Mason made 25 saves.
The Flyers forced overtime on Voracek's first goal of the season with 5:20 left in the third, at the end of a strong shift by the line of Giroux, Voracek and Michael Raffl. They had the Ducks pinned deep in their zone, and when the Ducks' Andrew Cogliano tried to clear the puck, Flyers defenseman Michael Del Zotto held it in at the point. He spun it deep for Voracek, who walked out from behind the Anaheim net to Andersen's right and beat him to the far side, over his glove.
The Ducks led 2-0 after one period, but the Flyers answered with two power-play goals late in the second. Anaheim stole back the momentum on Beleskey's goal with 16.7 seconds remaining in the period.
Elevated to the top line Monday after Patrick Maroon was injured in the second period, Beleskey has scored in three straight games.
Beleskey carried the puck into the Philadelphia zone along the right side and dropped a pass for Ryan Getzlaf. The Anaheim captain lost the puck but regained it along the wall. He spun away from Flyers forward Matt Read and spotted Beleskey cutting to the net behind the Flyers' Nick Schultz and Sean Couturier, who collided, leaving a lane for Getzlaf to thread a pass. Beleskey made one deke and lifted the puck over lunging Mason.
"That was big," Getzlaf said. "We hadn't had the best game either as a line. We were scrambling around the whole time. It was nice to get a little possession time and make some plays out there."
The Flyers had worked hard to tie the game in the second. They took advantage of three Anaheim penalties, including a 5-on-3 power play that led to Streit's goal at 12:43 of the second.
Despite playing the second game of a back-to-back against a Philadelphia team that had two days off, Anaheim opened the scoring on Jackman's goal at 12:20 of the first, then doubled their lead on Smith-Pelly's power-play goal at 16:53.
The Flyers are winless in their first four games for the fourth time in franchise history, first since 2008-09, when they started 0-3-1. The longest the Flyers have gone into a season without a win is six games, and that's happened twice -- in 1999-2000, when they started 0-5-1 before recovering to advance to the Eastern Conference Final, and in 2008-09, when they started 0-3-3.
Flyers coach Craig Berube was happy with the effort he saw.
"We played a solid game all game pretty much," he said. "We made a couple of mistakes, and they capitalized. The third goal is a mistake that can't be made. But other than that the guys played hard and did a lot of good stuff. In the end we don't win, [so] obviously it wasn't good enough, and we know that. But there were a lot of good things to build off of. We're going to go practice and get better."
The Ducks head home with six of a possible eight points on their trip. They're off until Friday, when they open a five-game homestand against the Minnesota Wild.
"It's not easy," Getzlaf said. "Makes the flight a lot easier when you battle back and get the two points you needed."
