Henrik Lundqvist stopped 29 shots for New York (8-3-3), which hit the road for the first time since a 4-1-1 homestand. The Rangers haven’t lost since Oct. 29 when Ottawa rallied from three goals down in the third period and won 5-4 in a shootout.
Gaborik, who extended his point streak to four games, and Stepan scored 2:17 apart to put the Rangers up 2-1 midway through the second period.
Stepan assisted on both of Gaborik’s goals, including the Slovakian right wing’s second of the game that gave New York a short-lived, two-goal lead 8:30 into the third. Artem Anisimov earned his second assist of the game on the goal.
Nick Foligno drew Ottawa within one 1:18 later, but the Senators’ comeback attempt fell short. Milan Michalek scored his 10th goal and Craig Anderson made 16 saves for Ottawa, which lost its fourth in a row.
Senators captain Daniel Alfredsson missed his fifth consecutive game because of a concussion.
Ottawa is 1-3-1 since losing Alfredsson, who was injured on a hit to the head by Rangers forward Wojtek Wolski in the previous meeting between the teams.
LIGHTNING 2, FLYERS 1 (OT)
In Tampa, Fla., Brett Connolly scored 2:30 into overtime to lift the Lightning.
Connolly won it after Dominic Moore skated into the Flyers’ zone and got the puck past a Philadelphia defender into the low slot, from where Connolly beat goalie Ilya Bryzgalov.
Marc-Andre Bergeron netted the tying goal in the third period for the Lightning, who have won seven of nine.
Scott Hartnell had the lone goal for the Flyers. Philadelphia routed Columbus 9-2 on Saturday but was shut down by Tampa Bay, which outshot the Flyers 24-15.
Philadelphia defenseman Chris Pronger returned after missing six games because of a right eye injury.
