UNIONDALE, N.Y. — Matt Martin capped New York’s three-goal second period, Ryan Pulock made a diving stop in front of an open goal in the closing seconds and the Islanders held on to beat the Tampa Bay Lightning 3-2 Saturday night to even their Stanley Cup semifinal series at two games apiece.

Josh Bailey and Mathew Barzal also scored, and Cal Clutterbuck and Adam Pelech each had two assists. Semyon Varlamov finished with 28 saves to help the Islanders win a Game 4 to tie a series after dropping the previous game at home for the third time this postseason.

Brayden Point scored for the seventh straight game, and Tyler Johnson also scored for the defending champion Lightning. Andrei Vasilevskiy finished with 27 saves.

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.
