NEW YORK — Brian Boyle scored at 2:48 of overtime to lift the Tampa Bay Lightning to a 5-4 victory over the New York Islanders on Tuesday night for a 2-1 lead in their second-round series.

Nikita Kucherov tied it in the final minute of regulation, and Ryan Callahan, Victor Hedman and Vladislav Namestnikov also scored for the Lightning. Ben Bishop stopped 35 shots.

On the winning goal, the Lightning were on an odd-man rush and Hedman fired a shot from the left side that was wide, but the rebound came off the boards and right to Boyle in front at the right side of the goal and he tapped it in for the win.
