New York— Keith Yandle set up two first-period power-play goals and Henrik Lundqvist made 39 saves and the New York Rangers beat Boston 5-2 on Wednesday night, sending the Bruins to a season-high fourth straight loss.

Mats Zuccarello, Derek Stepan, Derick Brassard, J.T. Miller and Rick Nash scored for New York, which won its second straight and inched a little closer to securing a spot in the playoffs with eight games left in the regular season.

Lee Stempniak, who had a first-period tally disallowed after an offside review and another shot gloved off the line by Lundqvist in the third period, scored for the Bruins along with Frank Vatrano. The Bruins have five goals in their skid.

The Bruins could not catch a break in this one, either with the replays or the officials. They gave the Rangers the first five man-power advantages, and New York converted on two of the first three in a game in which it was outshot 41-24.

Yandle was the key on both goals, making pinpoint passes to set up Zuccarello’s 24th at 8:37 and Stepan’s 17th a little more than three minutes later.

The turning point for Boston came between the goals. Stempniak seemly tied the game at 9:05, putting a rebound past Lundqvist.

The Rangers asked for a review and it showed Brad Marchand preceding the puck into the zone, nullifying the tally.

Fans entering the game at Madison Square Garden got a ‘Zucc Gnome’ in a Rangers’ giveaway, and the forward didn’t disappointment them. He beat Tuukka Rask from low in the right circle after taking a great pass from Yandle with Jimmy Hayes off for slashing.

Boston coach Claude Julien felt a deflection by Chris Kreider on the power play hit the netting, but the officials didn’t see it.

Stepan had an empty net to shoot at for a 2-0 lead after Yandle beat both Zdeno Chara and Patrice Bergeron and found him alone at the right side of the net.

Brassard scored his 26th of the season at 5:26 of the second period with a slap shot into the top corner of the net against Jonas Gustavsson, who replaced Rask at the start of the second period.

Stempniak got his good goal at 9:34 of the second period on a 2-on-0 with Marchand, but Miller iced the game early in the third on a nice setup by Stepan.

Islanders 3, Senators 1

New York — Brock Nelson and Matt Martin scored 21 seconds apart in the second period and New York beat Ottawa to snap a season-high four-game losing streak.

John Tavares also scored in the Islanders’ three-goal second period and rookie goalie Jean-Francois Berube, making just his fourth career start, stopped 22 shots.

New York, holding the first wild-card spot in the Eastern Conference, got a needed victory in its playoff push after going 1-4-2 in its previous seven games while getting outscored 22-11.

The Islanders pulled within one point of Pittsburgh for third place in the Metropolitan Division and moved four points ahead of Philadelphia and Detroit, who are tied for the East’s second and final wild card.

Mark Stone scored and Andrew Hammond finished with 20 saves for Ottawa, which lost its second straight after winning three of four.
