Ovechkin's power-play goal with 16 seconds left in the second tied the game 1-1. He scored on a one-timer from the top of the left circle after a pass from John Carlson.
"A little bit of a playoff feel out there," Oshie said. "Obviously, we have history with these guys from a couple of years ago in the playoffs (2016). It had that same feel. I think that's important for us, to get used to that. It's never too early to start playing playoff hockey."
The Flyers killed a tripping penalty on Raffl at 14:40 of the third to keep the game tied.
Elliott made several key saves, including one on Ovechkin at 10:57 of the first period and a follow-up chance by Evgeny Kuznetsov. Elliott's pad save on Nicklas Backstrom at 18:58 of the second period kept Philadelphia in front 1-0.
"[Elliott] was sure sharp tonight," Flyers coach Dave Hakstol said. "As much as it is rest, sometimes it's just a day or two of maintenance work. When you play as much hockey as he's played for us, you don't get those quality practice days. You forget the value of one or two days of good simple work."
Konecny, 20, and in his second NHL season, scored for the second game in a row and has four goals and six assists in his past 11 games. He moved to the top line with Claude Giroux and Sean Couturier on Dec. 23 after he had 10 points (four goals, six assists) in his first 35 games this season.
"We're talking a lot on the bench," Konecny said. "[Couturier is] teaching me a lot. [Giroux is] teaching me a lot. Like when to take off and the proper moments to not cheat, but take advantage of space. And also when I make little mistakes, they make me realize what I'm doing and capitalize on it."
