In their first three games together, the Jake Voracek-Sean Couturier-Wayne Simmonds line was extremely productive, combining for 10 points and a plus-13 rating.

"They seem to have some chemistry, regardless of who's in what spot," coach Dave Hakstol said Monday before the game against visiting St. Louis. "They're finding each other, using each other pretty well, and in the [offensive] zone there's a little more puck possession with three guys that protect it pretty well and they generate some offense that way."

Heading into Monday, Voracek had five points (two goals, three assists) and Couturier had four points (two goals, two assists) in their three games together. Simmonds - whose production was curtailed because of 34 penalty minutes in that span - had an assist.

Voracek, playing left wing for the first time in four years, said each of the players has accepted his role.

"Everybody is doing their own job. . . . We all understand each other," he said.

"We're supporting each other all over the ice, especially offensively," Couturier said.

Simmonds on guard

Simmonds has two instigator penalties this season, both in fights that started after he came to the aid of a teammate who was kneed. The next instigator penalty would trigger a game misconduct for that matchup and an automatic two-game suspension.

Hakstol was asked if Simmonds needs to show restraint the next time one of his teammates needs assistance.

"That one is for the rest of his teammates to realize. I'll leave it at that," Hakstol said. "They have to get in and take care of it. If something needs to be addressed, somebody else needs to address it. We can't afford to have him out for a couple of games."

Simmonds entered Monday third on the Flyers with 17 points.

Breakaways

The Flyers' next game at the Wells Fargo Center isn't until Jan. 5 against Montreal. . . . Claude Giroux began the night fifth in the NHL in faceoff percentage (58.2 percent). . . . The Flyers could have seven of their prospects play in the IIHF World Junior Championships: winger Travis Konecny and defenseman Travis Sanheim for Canada; defenseman Ivan Provorov and left winger Radel Fazleev for Russia; goalie Felix Sandstom and forward Oskar Lindblom for Sweden; and forward David Kase (Czech Republic). The competition will be held in Helsinki, Finland, from Saturday to Jan. 5, and GM Ron Hextall plans to attend.
