"If you look at a team like Arizona, they have a ton of shorthanded goals (10), and it just shows if the opportunity is there, you can take it," said Hanifin, whose goals were his first two with Calgary.
Hanifin scored on a power play at 8:34 of the second period to make it 3-0. James Neal had an assist on the play for his 500th NHL point.
"We had a good start and we progressed as the game went on and started playing faster and faster," Hanifin said.
Jankowski extended the lead to 4-0 at 11:25, scoring into an open net at the right post off a cross-crease pass from Brodie.
Brodie scored a shorthanded goal to make it 5-0 at 3:39 of the third period, and Jankowski scored another shorthanded goal 24 seconds later on a backhand from in front to make it 6-0.
