Barzal made it 2-0 with 6:14 left as he got the rebound of a shot by Clutterbuck from the right point and quickly put it into the open net from the left side with Kyle Palmieri screening Vasilevskiy in front. It was Barzal's sixth of the playoffs, all coming in the last nine games.

Game 5 is Monday night in Tampa, Florida, with Game 6 back at Nassau Coliseum on Wednesday night.

The Lightning pulled Vasilevskiy for an extra skater with about 1:50 left, but he returned to the ice 38 seconds later when Victor Hedman was called for tripping Clutterbuck to give the Islanders a power play.

Tampa Bay’s Ryan McDonagh had the puck on the left side in the waning seconds, spun around to get away from Brock Nelson and drew Varlamov forward before sending the puck at the open net. But Pulock's dive kept the puck out and preserved the win.

Vasilevskiy gave up his most goals since he allowed four in Game 4 of the second round against Carolina. He had a shutout in the series-clinching Game 5 and then had limited the Islanders to five goals in the first three games of this series.

Point got the Lightning on the scoreboard 3:45 into the third as he brought the puck up the right side and beat Varlamov with a shot from nearly 50 feet out. It was Point's league-best 12th of the postseason and tied Claude Lemieux (1997), Joe Sakic (1996), Mario Lemieux (1996), Pat LaFontaine (1992) and Mario Lemieux (1991) for the longest streak in the last 30 years.

Johnson made it 3-2 nearly 3 minutes later as he got the puck in the corner, skated around one Islanders player, moved toward the net and beat Varlamov up high on the right side with teammate Ross Colton and Pulock screening the goalie.

Varlamov had six saves over the first 3 minutes of the second, including consecutive tries in close by Point that drew chants of “Var-ly! Var-ly!” from the home crowd.

The Lightning were outshooting the Islanders 17-4 at the time, but New York dominated the rest of the period as it scored three times while outworking Tampa Bay with a 17-3 edge on shots on goal.

The Islanders got on the scoreboard at 5 1/2 minutes on their third shot on goal of the period — and seventh of the game. Nelson brought the puck up the left side, drew a couple of Lightning players to him as he spun around and sent a cross-ice pass to Bailey, who quickly beat Vasilevskiy high on the glove side from right circle for his sixth of the postseason.

Pelech sent a shot toward the net from the left side that was stopped by Vasilevskiy. The rebound went to the right side, where Martin backhanded it into the top left corner to make it 3-0 with 2:03 left. The Lightning challenged for offside on the entry into the offensive zone, but the play was upheld after a video review — confirming the Islanders' seventh three-goal period in 16 games this postseason.
