ATLANTA — Mikhail Grabovski's tip-in 39 seconds into overtime gave the Toronto Maple Leafs a 2-1 victory over Atlanta on Thursday night, damaging the Thrashers' playoff hopes.
Toronto rookie Jonas Gustavsson stopped 19 shots for his sixth straight win.
Ondrej Pavelec stopped 28 shots for Atlanta, but couldn't prevent Grabovski's winning shot. Grabovski punched in a shot by Dion Phaneuf past Pavelec's catching glove.
Atlanta's Zach Bogosian and Toronto's Phil Kessel traded goals midway through the first period. The 1-1 tie lasted through regulation.
The Thrashers remained three points behind eighth-place Boston for the final playoff spot in the Eastern Conference.
The Thrashers have scored only one goal in two straight losses following a four-game winning streak. Atlanta suffered a crucial 4-0 loss to the Bruins on Tuesday night.
Toronto is in last place in the Eastern Conference but has won seven of nine, including the rare road victory. The Maple Leafs improved to only 5-15-3 in their last 23 road games.
Bogosian gave the Thrashers a 1-0 lead with a power-play goal 10:40 into the first period. Bogosian's goal was his first since Jan. 16 at Carolina. He had eight goals through Nov. 15 and now has 10 for the season.
Kessel answered for the Maple Leafs about minute late with a shot past Pavelec.
