Slava Kozlov and Hossa, the first two shooters for Atlanta, beat Martin Brodeur. At the other end, Kari Lehtonen stopped Zach Parise and Brian Gionta. In regulation, Hossa broke out of a mild scoring slump by setting an Atlanta record for short-handed goals in a game. Jon Sim also scored, and the Thrashers extended their win streak over the Devils to five.
Sergei Brylin and Jamie Langenbrunner replied on the power play for New Jersey while defenceman Johnny Oduya scored his first career NHL goal.
The Devils outshot the Thrashers 3-1 in overtime. New Jersey's Brian Rafalski had the best chance with two minutes remaining.
Langenbrunner put New Jersey up 3-2 with a 5-on-3 power-play goal at 6:43 of the third. The celebration was short lived, though, because Hossa got his second short-handed goal only 19 seconds later.
Vitaly Vishnevski threw the puck ahead and Hossa grabbed it at centre ice before beating Brodeur from the top of the left circle.
Hossa wasn't done. Seconds later, he had another short-handed breakaway that Brodeur stopped with a sprawling save.
In the second, Brylin and Oduya scored to give the Devils a 2-1 lead before Sim got the tying goal for the Thrashers.
Brylin got his third goal in two games by backhanding the rebound from Parise's shot past Lehtonen at 6:37. Oduya scored at 9:09 on a slapshot from the left point.
Sim tied it 2-2 on a delayed penalty, converting Ilya Kovalchuk's rebound at 16:25.
Hossa gave the Thrashers the lead with his first short-handed goal at 7:59 of the first. Atlanta's top scorer picked up the puck in his own end, knocked over Rafalski as he gathered momentum in the New Jersey zone before cutting to the net to beat Brodeur unassisted.
