ST. LOUIS -- Jakub Voracek scored at 3:33 of overtime, and the Philadelphia Flyers ended the St. Louis Blues' home winning streak at nine with a 4-3 victory at Enterprise Center on Wednesday.
Voracek scored on a wrist shot from the slot to deny St. Louis its first sweep of a homestand of five or more games in its history.
"I think one guy changed, one guy got caught," Voracek said. "Usually when you have a bad change in overtime, it's on the rush. I thought it was going to be 2-on-1, then I had to slow down a little bit to have a little bit of time and space. I had nothing other than that, so obviously it worked out."

Brian Elliott made 30 saves, and Sean Couturier had two assists for the Flyers (25-16-6), who blew a 3-1 lead in the third period but won for the third time in four games.
"It was certainly a really solid game on our part," Flyers coach Alain Vigneault said. "We've played against some real tough opponents lately, Washington, Tampa Bay, and Boston, and to come in here tonight against the Stanley Cup champions, play the way we did, hard at both ends, there were some performers on the ice that were making it real challenging for us to keep our focus and our cool, but we did and we battled and we found a way to grind out and get a greasy road win against a real tough team."

Alexander Steen had a goal and an assist, Robert Thomas had two assists, and Jordan Binnington made 21 saves for St. Louis (30-10-8), which was trying to set a record for consecutive home wins. It won nine straight from Jan. 26-Feb. 26, 1991.
"It's a great homestand, no doubt about it," Blues coach Craig Berube said. "But listen, we want all of it. We're not happy with this performance, but I'm happy with the battle back and getting a point."
Ryan O'Reilly scored at 10:35 of the third period to cut the Flyers lead to 3-2, pouncing on a rebound of a Brayden Schenn shot, and Steen tied it 3-3 at 13:39 when he took a Thomas pass in the slot all alone and roofed a backhand.
"It was a great effort from us to battle back and get that point," Thomas said. "We would've liked to finish it off, but all in all, a good way to battle back."

Scott Laughton and Michael Raffl scored three minutes apart in the second period to give the Flyers a 2-1 lead.
Laughton scored after Tyler Pitlick's wraparound into the crease caromed off a Blues skate at 12:43 to tie it 1-1, and Raffl scored on a rebound of a Robert Hagg point shot at 15:43 to make it 2-1.
Travis Konecny increased the lead to 3-1 on the power play 26 seconds into the third period when he one-timed a James van Riemsdyk between-the-legs pass through the crease.
"When you come in playing a team like this on the road, we were definitely happy to take it into overtime," Konecny said. "To come out with a win is that much sweeter."

Justin Faulk's power-play goal, a one-timer at 14:24 of the first period, gave St. Louis a 1-0 lead.
Philadelphia killed off a 5-on-3 for 1:41 early in the third period to preserve its 3-1 lead.
They said it
"You could tell why they are so successful in the playoffs because I felt after we tied the game 1-1 they started playing physical and all 18 guys were finishing checks. They played really heavy for a while there. When they bring this kind of game in the playoffs, I see why they won last year." -- Flyers forward Jakub Voracek on the Blues
"I think we do a good job of staying in the moment and those things don't affect us in that manner. In saying that, we got a lot of big saves out of [Binnington] in the second period, probably could have been down more, and that kept us in it. We had a chance to get back." -- Blues forward Alexander Steen
