Travis Konecny also scored, and Samuel Ersson made 17 saves and had an assist on Zegras’ goal for Philadelphia (37-24-12), which also won 5-3 at the Detroit Red Wings on Saturday and is 8-1-1 in its past 10 games.

With the win, the Flyers are tied with the Red Wings and the Ottawa Senators at 86 points each, and are just two points out of the second wild-card spot in the Eastern Conference. They’re also two points behind the Pittsburgh Penguins for third place in the Metropolitan Division.

“The belief and confidence is pretty high right now,” Flyers defenseman Rasmus Ristolainen said. “… It’s really fun playing extremely meaningful games at this time of year. Obviously, every night is a big one. So very, very exciting.”

Arttu Hyry scored, and DeSmith made 28 saves for Dallas (44-18-12), which has lost five of its past six games; the Stars’ only victory in that span was 6-3 at the Pittsburgh Penguins on Saturday. They’ve already clinched a spot in the Stanley Cup Playoffs and with the point they received tonight, became the second team to reach 100 points for the season.

“One hundred points is not something you take lightly in the League,” Dallas coach Glen Gulutzan said. “Tonight was a hard game, symbolic of how hard it is to get here. But they’re playing hard. I thought it was a really stingy contest. I thought both teams looked pretty tired too. I thought it was a pretty even affair. They got the extra point, so we’ll just move on.”

After a scoreless first period, Konecny gave the Flyers a 1-0 lead with a power-play goal at 9:48 of the second. Konecny and Matvei Michkov passed the puck back-and-forth deep on the left side of the Stars zone. Konecny drove the puck to the net from below the goal line, wrapped around and deposited it past DeSmith’s left pad.

Hyry scored short-handed for his first NHL goal at 17:53. Flyers defenseman Jamie Drysdale tracked back into the Philadelphia zone to play a puck but fell, and Hyry snapped a shot far side, over Ersson’s glove, from the left face-off dot.

“I saw their guy kind of struggling with the puck and with his balance,” Hyry said. “Kind of guessed on that and got the puck. It’s just nice. Shoot it as hard as you can and hope it goes in.”
