Tampa Bay's Victor Hedman rattled in the game-winning goal in the shootout as the visiting Lightning won their third straight game, nipping the Washington Capitals 2-1 on Saturday night.
In the fourth round, the Lightning defenseman lost control of the puck slightly on approach, collected it and beat Washington goaltender Charlie Lindgren (19 saves) on the stick side for the game-winner as Tampa Bay moved to 7-3-0 in its past 10 matches.
Luke Glendening scored the game's first goal, while goalie Andrei Vasilevskiy made 33 saves to win in his seventh straight start (5-2-0) by stopping Dylan Strome, Alex Ovechkin and Connor McMichael in the shootout.
Anthony Mantha scored for the Capitals, whose three-game win streak ended. Washington played its fourth consecutive game that went beyond regulation.
Lightning defenseman Mikhail Sergachev (lower body) was scratched and missed his second straight game.
After earning home wins over the St. Louis Blues and Vegas Golden Knights earlier in the week, the Lightning started on the right foot in their first of three matchups against Washington.
Less than a minute after failing to score during the game's first power play, Tampa Bay went ahead 1-0 at 7:29 when its third line cashed in on a deflection. Glendening was credited with his fifth goal, with Hedman registering the only assist.
The Capitals successfully denied Tampa Bay on two power-play opportunities but could not score on their lone power play. Washington held a 13-11 edge in shots over 20 minutes.
In the second period, some quick passing near the blue line between Joel Edmundson, Aliaksei Protas and Nick Jensen led to a shot by Jensen toward traffic. The puck struck Mantha's leg, went in and tied the score at 2:01 for his 10th goal of the season.
Washington brought the crowd to its feet at 11:21 when Jensen appeared to score his first goal of the season with a fake at the blue line and high shot over Vasilevskiy.
But the Lightning challenged the goal occurred after an offside. The review determined that it was, erasing the Capitals' first lead.
In a defensive-oriented third, Washington held a 6-2 shot advantage over the Lightning, who had a fine chance snuffed when Lindren denied Nicholas Paul in close on a rush with less than two minutes remaining before heading to overtime.
