MONTREAL -- Brayden Schenn scored three goals to help the St. Louis Blues end a three-game losing streak with a 4-3 victory against the Montreal Canadiens at Bell Centre on Tuesday, ending the Canadiens' five-game winning streak.
Scottie Upshall also scored for the Blues (18-8-2) and Jake Allen made 22 saves.
Shea Weber scored two goals, including the 500th point of his career, and Jordie Benn scored for the Canadiens (13-13-3). Carey Price made 26 saves. It was Price's first loss since returning from a lower body injury six games ago.
Schenn's third goal at 12:11 of the third period, which deflected off the skate of Montreal defenseman David Schlemko, broke a 3-3 tie and gave the Blues the win.
After the Blues scored goals seven seconds apart by Upshall and Schenn early in the second period for a 3-1 lead, Weber cut it to 3-2 with 2:56 left in the second period when he scored off a faceoff won by center Andrew Shaw. His shot sent the puck rolling on its edge, starting outside the right post and curling by Allen's skate.
Weber tied it at 6:34 of the third period on a similar play: a Shaw faceoff win in the right wing circle back to Weber, who scored on a slap shot through Allen's pads.
The Blues sliced through the Montreal defense to take the 3-1 lead early in the second period.
First it was Dmitrij Jaskin skating down the right wing against Benn and finding room to slip a backhand pass across the slot to Upshall, who beat the check of Montreal wing Brendan Gallagher to get a shot off and score his fourth goal of the season.
Schenn scored his second goal of the game when he took a pass from Alex Pietrangelo in the neutral zone, split the Montreal defense and scored to the glove side on Price.
Benn had tied the game 1-1 at 15:28 of the first period when his rising shot from the right point went in over Allen's right shoulder with Canadiens forward Daniel Carr providing a screen. It was Benn who drew the penalty that led to the power play when he was hooked by Blues left wing Alexander Steen.
Schenn ended a five-game streak without a point when he made it 1-0 at the five-minute mark, snapping home a pass from behind the net by Jaden Schwartz after Schwartz had chased down Schenn's rebound at the right post.
