The Tampa Bay Lightning moved first in the NHL's Eastern Conference with a 4-1 win over the Vancouver Canucks on Tuesday.

Alex Killorn struck a double for Tampa Bay, while Ben Bishop made 27 saves as the Atlantic division leaders climbed to the top of the East.

The win - the Lightning's eighth in a row at their Amalie Arena - came after a goalless first period.

Valtteri Filppula broke the deadlock in the 14th minute of the second period before Killorn and Brian Boyle scored in the early stages of the third.

That meant Frank Corrado's goal was little more than a consolation for the Canucks, before Killorn struck again to seal an important win for the Lightning heading into the league's All-Star break.

Defeat for Vancouver ended their three-game winning streak.
