After Tarasenko scored, the emphasis became getting the win for Binnington, the Blues said.
"Right when we got that second goal, we know they're going to be coming, throwing everything at the net," said forward Ryan O'Reilly, who had two assists. "You could tell on the bench, guys are talking, we got to get this one for him, it's his first one. He played a great game all night. Do whatever you can to keep the puck out of the net."
Binnington was called up from San Antonio of the American Hockey League on Saturday. The 25-year-old, a third-round pick (No. 87) by St. Louis in the 2011 NHL Draft, was named AHL player of the week earlier Monday.
"I was definitely excited to finally get the call, and it was a long road," he said. "I'm happy where I'm at right now and I'm hoping to get some more action and be a part of the solution on the rise of the Blues."
The Flyers had 11 shots on goal in the first period but 14 in the second and third.
