Binnington, who was drafted by the Blues in the third round in 2011 and had played 157 games in the OHL, 40 in the ECHL and 164 in the AHL, waited a long time for the moment.
"It feels good, for sure," Binnington said. "I was definitely excited to finally get the call. It was a long road, and I'm happy where I'm at right now and I'm hoping to get some more action and be part of the solution on the rise with the Blues.
