OTTAWA (AP) – Slava Kozlov scored his second goal of the game 1:48 into overtime to lift the Atlanta Thrashers to a 3-2 win over the Ottawa Senators on Monday.

Kozlov, who gave Atlanta a 2-1 lead midway through the second period, beat Ray Emery with a backhander between the legs on a breakaway with a delayed penalty signalled against Ottawa.

Senators defenseman Tom Preissing scored Ottawa’s second power-play goal on a slap shot from the point 16:05 into the third to tie it at 2.

Thrashers leading scorer Marian Hossa got his third assist of the game on Kozlov’s overtime winner. He also set up second-period goals by Ilya Kovalchuk and Kozlov to end his former team’s four-game winning streak.

Hossa, traded by Ottawa to Atlanta prior to last season, assisted on Kovalchuk’s power-play goal 4:51 into the second period to tie the game at 1. Kozlov’s first goal came at 11:16.

Kari Lehtonen stopped 33 shots for the Thrashers, who have won six of seven. Atlanta lost 4-1 in Buffalo on Saturday to end its second five-game winning streak of the season.

Senators captain Daniel Alfredsson scored Ottawa’s other power-play goal in the opening minute of the second period.

Emery made 26 saves for the Senators, who lost for the first time in five games since losing high-scoring center Jason Spezza to a knee injury.

Atlanta had a potential goal waved off 14:18 into the third when the referees determined that Emery had been pushed into the net by Thrashers forward Jason Krog.

Ottawa, which also recently lost center Mike Fisher to a knee injury, was missing its top three centers. Antoine Vermette didn’t play because of a hip injury he suffered in Saturday’s 3-2 overtime win in Toronto.

Former Senators defenseman Shane Hnidy, whose holding penalty led to Preissing’s goal, prevented an Ottawa goal in the first when he stopped a loose puck from crossing the goal line with his stick and swiped it under Lehtonen.

After Alfredsson beat Lehtonen for his 11th goal, Kovalchuk scored his 21st goal when he one-timed a slap shot past Emery from the left point on a crisp passing play begun by Hossa and continued by defenseman Niclas Havelid.

Hossa also played a prominent role in giving Atlanta a 2-1 lead midway through the middle period. Kozlov got his 16th goal when he put a rebound of Hossa’s shot.

Notes: Hossa has recorded 27 of his 55 points on the power play. … C Serge Payer joined the Senators’ lineup after he was recalled from Binghamton of the AHL on an emergency basis earlier in the day. Ottawa C Josh Hennessy played his third straight game since also being an emergency callup Friday.
