Slafkovsky hat trick stuns Lightning

The Montreal Canadiens opened their first-round series with a dramatic upset win against the favored Tampa Bay Lightning.

Juraj Slafkovsky, the former number one overall pick, dominated the game with three power-play goals, including the overtime winner.

The victory gives Montreal an early lead in their quest for a first playoff series win in five years.

Tampa Bay, who have struggled at home in recent postseasons, will look to even the series in Game 2.
