John Tavares scored two power-play goals 30 seconds apart in the third period as the New York Islanders closed out a seven-game homestand by beating the Washington Capitals 5-2 on Saturday.

Tavares broke a 2-2- tie with 7:47 remaining when he fired a rebound past rookie goaltender Philipp Grubauer, who was making his first NHL start. He then rocketed a wrister past Grubauer 30 seconds later on a shot that originally was ruled no goal. Play went on for more than two minutes until Matt Moulson scored – only to have his goal taken away.

Tavares now has 16 goals, tying him for second in the NHL with Jeff Carter of the Los Angeles Kings. Both trail Steven Stamkos of the Tampa Bay Lightning, who leads the League with 18 goals.

Frans Nielsen added a shorthanded breakaway goal with 3:01 to play. Josh Bailey and Casey Cizikas also scored as New York (11-11-3) finished the long homestand with a 3-2-2 record, including 3-0-2 in their last five games.

The Capitals got goals from Joel Ward and Nicklas Backstrom but had their three-game winning streak snapped and lost for just the second time in their last nine visits to the Nassau Coliseum.

Grubauer finished with 40 saves while Evgeni Nabokov, who is 16 years older than his Washington counterpart, made 22 saves.

For a moment, it looked like the Islanders might fritter away another third-period lead. They led 2-1 after two periods, but the Capitals tied it at 7:09 when Backstrom took a pass from Eric Fehr and one-timed a rocket past Nabokov for this third of the season.
