Mikhail Sergachev scored in the third period to put Utah ahead to stay, and the Mammoth held on for a 4-3 win over the Florida Panthers on Tuesday night. Nick Schmaltz, Sean Durzi and Barrett Hayton also scored goals for the Mammoth, who have won nine of their last 11 games and played without top goal-scorer Dylan Guenther, who has a lower-body injury. Vitek Vanecek made 25 saves and Durzi also had an assist.
