Carey scored again at 13:00 of the middle frame. Desharnais stopped short near the hash marks and found Carey alone in the slot. Jimmy Vesey also assisted on the play.
Desharnais had been playing well on the top line while center Mika Zibanejad missed nine games with a concussion, but Zibanejad returned Tuesday. Rangers coach Alain Vigneault slid Desharnais to the fourth line, but he still contributed and has nine points in his last 10 games.
Grabner scored his 17th of the season at 16:37 of the third for a 4-1 lead. The speedy Austrian forward converted on his own rebound.
