Jordan Kyrou had two goals and two assists, and the St. Louis Blues scored five times in a 5:07 span of the second period for a 7-4 victory over Arizona in the Coyotes' home opener Monday night.
Kyrou and Klim Kostin had two goals apiece during the second-period flurry, which began when Justin Faulk scored on a power play to tie it 2-all at 11:10 after goalie Carter Hutton lost his stick during a scramble in the crease.
Kyrou scored his first goal after a Coyotes giveaway at 12:46 to give the Blues a 3-2 lead, and Kostin got two goals 47 seconds apart to make it 5-2 as Arizona had trouble getting the puck out of its own end.
Hutton was pulled for Karel Vejmelka after Kyrou skated in alone to cap the scoring burst for a 6-2 lead at 16:17.
Pavel Buchnevich and Ivan Barbashev also scored for the Blues, who have won the first two games of a season-opening three-game road trip.
Jordan Binnington made 22 saves for the Blues.
Buchnevich was given a five-minute major penalty and ejected with 1:07 remaining in the first period for headbutting Lawson Crouse, whose goal gave the Coyotes a 2-1 lead early in the second.
The Blues play at Vegas on Wednesday. They have not opened with three straight on the road since 2006.
