Thanks to tiebreakers, the Devils are still in the No. 7 spot, but the Islanders and Rangers are catching up fast.
The Caps, keyed by Alexander Ovechkin's three-point game, crept to within three points of the eighth spot, and are only two points back of No. 3 Winnipeg for the Southeast Division lead.
Carolina still has one game in hand on the Caps -- two on the Jets -- and are only four points behind Winnipeg.
Another huge night comes tonight, starting with the Rangers and Penguins. New York, with a win, would create a three-way tie for eighth.
The Penguins, who had their 15-game win streak snapped Tuesday, will inch closer to the postseason with a win.
The Flyers, not pictured but six points back of New Jersey and the Isles, will host Montreal in a game they need. Philadelphia has two games in hand on the eighth-placed Islanders.
The Canadiens, with a win and Pittsburgh loss, will move to within three points of the Pens for No. 1 in the East.
The full slate of Eastern Conference games:
Pittsburgh at N.Y. Rangers, 7
Montreal at Philadelphia, 7:30
