NEW YORK — Chris Kelly snapped a second-period tie, and Martin Gerber came back from a day off to lead the Ottawa Senators to a 3-1 victory over Sean Avery and the New York Rangers on Sunday night.

Gerber, who sat out the Senators' 4-3 overtime loss to Chicago at home on Saturday night, made 34 saves to earn his fourth win in five outings. He gave up Scott Gomez's goal 3:42 in and then held off New York the rest of the way.

Jason Spezza and Kelly wiped out an early deficit for the Senators, who lead the Eastern Conference with 50 points (23-8-4). Ottawa got back to its winning ways after going 0-1-1 following six straight victories.

Thrashers 3, Blues 2 (OT): At St. Louis, Marian Hossa scored on a break-in at 19 seconds of overtime after a defensive mistake, and Ilya Kovalchuk scored his NHL-leading 29th goal for Atlanta.

Hossa swept in alone on goalie Manny Legace after Jay McKee fumbled the puck in the air and then lost control after Eric Perrin flipped it into the St. Louis zone.

The Thrashers have won four in a row, beating Montreal by the same score in a shootout Saturday, after losing their previous four games, and won in St. Louis for the first time in franchise history.

Kovalchuk has 25 goals and 16 assists in the last 28 games for the Thrashers, who climbed above .500 at 18-17-1. Mark Recchi tied it in the third period with his fourth goal in seven games since being claimed off re-entry waivers on Dec. 8.
