Bortuzzo's current contract was set to expire at the end of the 2016-17 season. The extension will now keep Bortuzzo in St. Louis through the 2018-19 season.

"I wanted to be here and it sounded like they wanted me here, so we got it done," Bortuzzo said. "The town, the team, the organization, they're all world-class. It's been great. There's a great core here, and I feel like I can be part of it moving forward."

"He's the glue to the team," added Blues Head Coach Ken Hitchcock. "He's able to get along with everybody, he brings an energy into the game. He's eliminated all those mistakes (in his game) and now he's just flat a good player. When he's playing, our team plays really well... his enthusiasm for his teammates really invigorates the locker room. When he's not here, there's a noticeable difference."

Bortuzzo has played in 64 career games with the Blues, registering four goals, three assists and a plus-5 rating.
