Carolina built a three-goal lead before defenseman Jake Walman - the Blues' third round pick (No. 82 overall) in the 2014 NHL Draft - put St. Louis on the scoreboard midway through the third period.
Robert Thomas, a 2017 first-round pick who is expected to compete for a roster spot in training camp this season, recorded an assist on Walman's goal.
"A broken play in the neutral zone, just good instincts by both players," Blues Head Coach Mike Yeo told stlouisblues.com of Walman's goal. "Robby, as far as the way he picks up the puck and moves his feet to create the 2-on-1, and then that's what the skating ability of a guy like Walman can do. When you get your defenseman involved in the rush and the attack, and obviously with his shot and the ability to finish... it was a great play by both guys."
Carolina had a 2-0 lead after the first 20 minutes of play on goals from Morgan Geekie and Julien Gauthier. The Blues responded in the second period by getting the better of the play, but were stymied with some big saves from Hurricanes goaltender Jeremy Helvig.
After Walman cut the 'Canes lead to 3-1, Janne Kuokkanen sealed the win for Carolina with a late goal.
