Mike Fisher assisted on Alex Kovalev's first-period goal and added a power-play goal in the second, leading the Ottawa Senators to a 4-2 victory over the Atlanta Thrashers on Saturday night.

Fisher, who had scored 32 seconds into overtime Thursday night for a 3-2 win over the New York Islanders, restored Ottawa's lead 3:44 into the second when he put a backhander past Ondrej Pavelec.

New Senator Kovalev scored his first Ottawa goal 43 seconds in, and Jarkko Ruutu added Ottawa's second goal 1:42 later to open up a 2-0 lead 2:25 into the game.

Chris Neil also scored, and Brian Elliott made 27 saves in his first start of the season for Ottawa (3-1).

Atlanta's Ilya Kovalchuk scored his fifth goal in three games midway through the first. Ron Hainsey scored late in the period to draw the Thrashers even at 2.

Pavelec made his third straight start and stopped 30 shots.

Vyacheslav Kozlov appeared to have drawn Atlanta (2-1-0) within one midway through the third, but the goal was immediately waved off. A video review supported the referee's ruling that Kozlov had deflected the puck with a high stick.

Zach Bogosian recovered from a solid bodycheck by Senators defenseman Anton Volchenkov in the second period to level Ottawa captain Daniel Alfredsson immediately afterward with an open-ice hit of his own.

Chris Phillips drew a roughing minor at 13:27 as a number of Senators came to Alfredsson's defence after Bogosian knocked him to the ice in the neutral zone.

Kovalev, who left Montreal to sign a two-year, $10-million deal with Ottawa, got his first goal in four games with a shot into a gaping net 43 seconds in. Ruutu got his first of the season at 2:25 to make it 2-0.
