"We were down 4-3 there and two big goals, first shift, second shift," said Gaudreau, who is the first player to record six points in a game since Jamie Benn of the Dallas Stars did it against Calgary on Nov. 14, 2013. "Next thing you know, we're playing with the lead in the third and we kind of ran away with it."
Ryan scored his second on a tap-in off a pass from Gaudreau on a 2-on-1 to extend the lead to 6-4 at 2:37, and Gaudreau completed the hat trick with a backhand five-hole at 12:01 to make it 7-4.
Monahan converted from in front with 1:19 remaining to make it 8-4, and Matthew Tkachuk scored his 30th goals of the season 16 seconds later to push the lead to 9-4.
"Sometimes you're fighting the puck, sometimes you're feeling good, you're getting looks, you're making plays up and down the ice," Gaudreau said. "Our line was clicking tonight. We knew we had some jump in there from warm-ups, and we came in the locker room and we knew we were going to have a good night."
Gaudreau scored five-hole off a backhand deke to put Calgary up 1-0 at 5:05 of the first period.
