Clayton Keller and Nick Schmaltz each had a goal and an assist, sparking the Arizona Coyotes to a 6-2 victory Thursday night against the St. Louis Blues. “I think they work extremely hard. Today, they had their execution,” Coyotes coach Andre Tourigny said about Keller and Schmaltz. “I don’t think they had that since the beginning of the season. They weren’t connecting like they did tonight. They connected and they made plays. They were good.”
