The 30-year-old center, in his seventh season with the Senators, accomplished the feat with a slick short-handed goal, the go-ahead tally in the closing minutes of the third period, and an empty net score. The Senators, who hadn't scored in more than 200 minutes before Kelly's first goal, won for the third time in 11 games (3-7-1).
"I scored a hat trick this preseason but the guys said that didn't count, so I have to go back to juniors for my last one," said Kelly, who played for the London Knights and Sudbury Wolves in the Ontario Hockey League between 1997-2001. "It sure felt good to get one for real in the NHL."
Kelly, who doubled his season goal total to six, gave Ottawa a 1-0 lead in the second period with a short-handed score. His game-winner snapped a 1-1 tie off a feed from Jarkko Ruutu in front of the right post. The center flipped the puck over goalie Henrik Lundqvist's right shoulder with 2:24 remaining. Kelly completed the hat trick with an empty-net goal in the final second of the game.
Pascal Leclaire made 25 saves for his second win of the season (2-6-1). The struggling Senators (12-14-2) had been shut out in their previous two games at home.
"We played hard. I thought the guys persevered," Senators coach Cory Clouston said. "This is a building where it's hard to get momentum. The crowd gets into it. We wanted to make sure we got pucks in deep. We did that."
Brandon Prust scored a short-handed goal for the Rangers (16-12-1), who lost for only the third time in nine games. New York was 0 for 4 on the power play.
"New York is playing very well right now. It's a really good win," Clouston said.
Rangers coach John Tortorella was perplexed by his team's lethargic play in a rare 5 p.m. start.
"That better not be a reason for our slow start," Tortorella said. "We were off balance and asleep for the first 20 minutes. Even with that, this was a winnable game."
The Rangers were off on Saturday while the lost 1-0 at home in a shootout against Buffalo Sabres. New York swept a home-and-home series from the New York Islanders n Thursday and Friday.
Lundqvist finished with 22 saves for the Rangers, who will finish a home-and-home series against the Senators with a visit to Ottawa on Thursday night.
"They started a lot better than we did," said Lundqvist, just 3-6-1 at home, but 11-10-1 overall this season. "We were in this game. We worked ourselves back and we definitely had an opportunity to win it. We just came up short."
Kelly put the Senators ahead 4:27 into the second after Rangers forward Derek Stepan couldn't keep the puck in the Senators zone. He stole the puck and skated in alone on Lundqvist, beating him with a wrist shot from the left circle as Jesse Winchester served a penalty for tripping New York defenseman Steve Eminger.
It was the first goal in 202 minutes, 57 seconds for the Senators, who also lost 4-0 at home to San Jose on Thursday. Ottawa's previous goal was scored by Nick Foligno at 6:30 of the first period of a 4-1 home loss to Edmonton on Monday.
Prust got the Rangers even at 10:50 of the second, beating Leclaire with a wrist shot from the left circle on a 2-on-1 break with defenseman Marc Staal. It was Prust's third goal of the season and second in three games. It was also New York's sixth short-handed goal.
Rangers forward Ryan Callahan was also baffled and frustrated by the lack of offense.
"You go in and prepare the same way, but for whatever reason, we didn't get the start we need," he said "We had a better second and third, but our start definitely has to be better."
Kelly recalled that a 2-0 Ottawa victory at Madison Square Garden on Jan. 14 propelled the Senators on a team-record, 11-game winning streak last season.
"Hopefully this is the start of another good run for us," he said. "We've really struggled of late, so this win is very important."
