Defenseman Tony DeAngelo scored on a breakaway 33 seconds into overtime as the New York Islanders extended the NHL's longest winning streak to seven games, edging the host Tampa Bay Lightning 3-2 on Saturday night.

After the Islanders won the faceoff, Bo Horvat skated deep into the defensive end. During a line change, DeAngelo hopped on the ice while the Lightning were also changing, took a three-quarters ice stretch pass from Horvat and beat Andrei Vasilevskiy (33 saves) for his first New York marker.

Another newcomer, defenseman Adam Boqvist, scored in his Islanders debut, and Kyle Palmieri notched a goal in his second consecutive match. Goalie Ilya Sorokin stopped 28 shots as the club secured its fifth straight road win.

Jake Guentzel and Nikita Kucherov scored for the Lightning, who dropped to 2-4-1 in their past seven outings.

Vasilevskiy made one of his 13 saves in the first period on Simon Holmstrom's wrister at 14:35 on an odd-man rush, and another on Maxim Tsyplakov's point-blank shot three minutes later.

Sorokin, who stopped 12 shots in the period, denied a sneaky shot by Kucherov from the left circle with just over two minutes left.

In the second, Guentzel broke the scoring drought at 5:39 when he clipped a long shot by Erik Cernak for a 1-0 lead, giving the big defenseman an assist and his 99th career point.

After killing off the third consecutive Lightning power play, the Islanders caught a break when Mathew Barzal blew past Cernak, who slipped and fell, on a breakaway that Vasilevskiy stuffed.

However, Boqvist, who was picked up Friday after being waived by the Florida Panthers, crashed in and potted the rebound at 18:16 for his third goal overall and first with his new club.

Just after the Lightning killed off the visitors' first man advantage in the third, Palmieri hit the net at 6:41 off a feed from Tsyplakov, who had the puck behind Vasilevskiy's net.

With Vasilevskiy off the ice for the extra skater in the final two minutes, Kucherov scored with 47 seconds remaining to force overtime.
