The Flyers outshot the Blues 20-6 in the third period and overtime. Philadelphia's best chance came when Sanheim had a breakaway with 12 seconds remaining in overtime, but Binnington made a blocker save.
"He kind of outwaited me," Sanheim said. "If I had just waited a second, he's sliding to his left, I probably had the far side. I was going at pretty good speed but a nice save by him."
It's the second straight game Binnington has allowed one goal; he made 21 saves in a 3-1 win against the Minnesota Wild on Saturday that ended a three-game skid (0-2-1).
"No question Binner was outstanding for us tonight," Blues coach Drew Bannister said. "I didn't think we were very good in front of him. We just mismanaged the puck, caused ourselves a lot of issues, especially in the first [period] and the third. I thought we were a little bit better in the second, but the first and the third, just not able to get pucks deep, forced us to have to defend and had to rely on our goalie a lot here tonight."
NOTES: Flyers defenseman Nick Seeler left the game with 9:22 remaining in the third period. Seeler had gone to the locker room after blocking a shot with his left foot with 3:00 remaining in the second period but returned for the start of the third. There was no update after the game. ...
