Vladimir Tarasenko scored twice and Chris Stewart tied it with 6:27 remaining in regulation for St. Louis, which entered tied for the fewest regulation losses in the league with six and have now won three straight and four of five. Brenden Morrow added two assists and Jaroslav Halak made 30 saves for the Blues.
On the winner, Columbus lost the puck at its blue line. Backes took it, fended off Fedor Tyutin on a delayed penalty call then deked Mike McKenna and calmly scored with a high shot.
He's only 17 but he can see the ice so well and he moves the puck and goes to the open ice all the time, so I just think he's a player that is ready to play in the NHL. I'm really looking forward to coaching someone like this.
