The Islanders were ahead 3-1 midway through the third period when Colin McDonald fed Mouillierat in the slot. The rookie then proceeded to fire a shot past Mike Smith and into the net for his first National Hockey League goal. He also gave the Islanders the 4-1 lead.
"It's obviously a pretty unbelievable feeling," Mouillierat said about his first goal. "You play so long and especially at my age to get your first crack at the NHL. There's times in the minors when you think it's never going to happen and then when it does it's pretty incredible. It's obviously a great feeling."
Mouillierat's goal was one of four that the Islanders scored in the third period that helped lead them to a 5-1 victory over the struggling Coyotes. Matt Martin's eight goal of the season 3:18 into the third period gave the Islanders a 2-1 advantage.
A Johnny Boychuk shot 57 seconds later beat Mike Smith and gave the Isles a two goal advantage. Mouillierat's goal and Brock Nelson's goal at 9:10 all but sealed the win.
"We just kept doing the right things, we kept doing the same things and eventually we got some opportunities," Johnny Boychuk said about the explosive third period. "We capitalized on them. You have to work for everything and we worked tonight, and we got rewarded."
The Islanders and Yotes had been tied through two periods. The Islanders scored in the second period. but Arizona answered back when Mark Arcobello beat Chad Johnson stick side to tie the game. Johnson finished the game with 27 saves and the Isles outshot the visitors 39-28.
Mouillierat will send the puck he scored his first NHL goal with back home to his parents, who just missed seeing their son score Tuesday night.
"My parents were actually out for the firset two games then they had to catch a flight home today," Mouillierat explained. "So they missed tonight’s game. Came a game late, but I’ll send it back home."
