Oshie, whose father died this week, completed his hat trick with an empty net goal at 18:20 of the third.
Rangers rookie Alexis Lafreniere ruined Vanecek’s shuout bid at 1:15 of the third period with his 11th goal of the season. Fellow rookie forward Morgan Barron scored his first NHL goal at 18:44 to complete the scoring.
The Capitals moved into a first-place tie with idle Pittsburgh in the East Division. Washington has three games left while the Penguins have two.
The dismal loss — the Rangers’ fourth straight — came in their home finale and on the same day the organization stunningly fired President John Davidson and General Manager Jeff Gorton. The team said former Ranger Chris Drury would take over both jobs.
The contest also followed Monday’s 6-3 loss to the Capitals in which Washington forward Tom Wilson pummeled Rangers top scorer Artemi Panarin after Wilson had punched Buchnevich during a scrum near the Capitals net. The loss eliminated the Rangers from the playoffs for the fourth straight season.
Wilson was assessed 14 minutes in penalties but not tossed from the game. On Tuesday, the NHL fined the Capitals agitator $5,000 leading the Rangers to issue a scathing statement criticizing the league and director of player safety George Parros.
