Van Riemsdyk scored his first goal in 13 games to give the Flyers a 4-1 lead at 8:09 of the third period, getting to the net during a power play and tipping Claude Giroux's shot.
It was van Riemsdyk's first three-point game since Oct. 26. He had four assists in his previous 12 games.
"When you're not scoring you've got to try to make sure you're solid with the other aspects of your game," van Riemsdyk said. "I think I've been trying to focus on that and do a good job of being strong on the walls, not turning pucks over, being responsible in my own end, things like that."
Van Riemsdyk set up Konecny's first goal, which gave the Flyers a 1-0 lead at 3:48 of the first period. In the second period, he won the puck behind the net, skated toward the corner and found Konecny open at the hash marks, where he made it 2-0 at 3:44.
"He makes those [plays] all the time," Konecny said. "They may go unnoticed, but he's an incredible passer. Thankfully, we could capitalize on a few of them tonight. He was in his office and scored a goal too."
