Victor Hedman scored the only goal in the shootout Friday night to lift the Lightning past the Islanders 1-0 after both goaltenders put on a spectacular display through 65 minutes.
Hedman beat Thomas Greiss on the first attempt for the league-best Lightning.
The Islanders had a power play at 3:23 of overtime when Tampa Bay’s Nikita Kucherov was called for cross-checking but couldn’t convert.
Greiss and Tampa Bay’s Andrei Vasilevskiy put on a save-for-save clinic before the shootout.
