GLENDALE, Ariz. - David Backes scored four goals to lead the St. Louis Blues to a 6-0 win over the Arizona Coyotes on Tuesday night.
Paul Stastny and Jayden Schwartz also scored for St. Louis and Brian Elliott stopped 23 shots. The Blues outshot the Coyotes 39-23 and won in Arizona for the sixth straight time with a 29-8 scoring in those games.
Backes notched his 10th, 11th, 12th and 13th goals of the season over a 17-minute span between the second and third periods. It was the second time Backes has scored four goals in a game and he became the second Blues player in two nights to score at least three goals, following T.J. Oshie's hat trick in St. Louis' 7-2 win at San Jose on Saturday.
Mike Smith finished with 33 saves for the Coyotes, who were shut out for the seventh time this season ? the fourth time at home.
Backes' first goal came after the Blues finished three passes with the puck coming to him for the shot, giving St. Louis a 2-0 lead. Just over a minute later at the 7:21 mark, Backes finished a breakaway after a pass from Oshie, also on a power play.
Backes scored again with a wrist shot past Smith with 5:07 left in the second period, and completed his night by putting in a centring pass from Alexander Steen at 3:15 of the third period. Backes has three career hat tricks, with Oshie recording a point for the sixth straight game after his two assists.
Patrik Berglund and Steen added two assists for St. Louis.
Stastny opened the scoring at 7:57 of the first period, putting in a loss puck after Smith came out of the net to stop a shot. Smith passed the puck to Lauri Korpikoski, who lost the puck to Stastny.
Schwartz capped the scoring with a power-play goal ??? St. Louis' third of the game ??? at 5:53 of the third.
The Blues scored on their first two power plays of the night. That led to a fight between St. Louis' Ryan Reaves and Arizona's B.J. Crombeen, which resulted in 5-minute penalties for both at 8:48 of the period.
Korpikoski had a good chance for a goal with just under 6 minutes left in the second, but couldn't corral a loose puck that Elliott couldn't find.
