Valimaki, who also had two assists, scored off Clayton Keller's backdoor pass. Matias Maccelli then scored an empty-net goal at 19:21 for the 4-2 final, completing a three-goal rally in the third period for Arizona.
"Some of those plays [Keller's] making right now, it's unbelievable," Valimaki said of his first goal in 39 games since Dec. 21. "All of a sudden, the puck was on my stick tape, and I just tried to slop it in and it went in, and about time I'd say."
Keller also had a goal and two assists, and Ivan Prosvetov made 32 saves for the Coyotes (27-32-11), who won their fourth straight and are 6-0-2 in their past eight. They've won six in a row at Mullett Arena, their longest streak at home since an eight-game run from Oct. 19-Nov. 16, 2013 at Gila River Arena.
"When you win you want to do it again, and then you want to do it again and you just come in and work," Valimaki said. "Obviously, everyone's playing really well. I think we're pretty confident in we're doing right now … and our goalies are playing really well."
