Chris Kelly scored all three goals for Ottawa, including the tiebreaking tally late in the third period of the Senators' 3-1 victory over the New York Rangers on Sunday night.
Kelly snapped a 1-1 tie off a feed from Jarko Ruutu in front of the right post. The center flipped the puck over goalie Henrik Lundqvist's right shoulder with 2 minutes, 24 seconds remaining. Kelly completed the hat trick with an empty-net goal in the final second of the game.
