Since winning five of eight at home to begin the season, Atlanta hasn't found the same success there lately.
But on Sunday night, the Thrashers go for their second straight win at Philips Arena and seventh straight at home versus Southeast Division rival Tampa Bay.
Atlanta (13-21-5) defeated Vancouver 4-3 in a shootout on Friday to snap a four-game losing streak. Erik Christensen scored the game-winner in the fourth round as the Thrashers won their first home game since defeating the Lightning 4-3 on Dec. 20.
"I don't know what it is with a shootout," said Christensen, a fourth-year center with 16 career shootout goals. "I'm always calm, which is different than during the game."
Christensen has 36 goals in 178 career games, including only one in 25 contests this season.
Ilya Kovalchuk, Slava Kozlov and Joey Crabb scored in regulation for Atlanta, which has outscored Tampa Bay 22-12 while winning the last six matchups at Philips Arena.
Kovalchuk has nine goals and five assists in his last 11 games against the Lightning.
Kozlov's goal was his first since he scored 18 seconds into the win versus the Lightning last month that snapped Atlanta's 0-5-2 skid at home.
Kari Lehtonen stopped 35 shots on Friday, picking up his first win since making 36 saves in the Thrashers' victory over the Lightning on Dec. 20.
"This is a game we can build on," said Lehtonen, 7-0-1 with a 1.60 GAA in his last eight starts against Tampa Bay. "We played well in the third (period). It's too bad (the Canucks) were able to tie the game."
While Atlanta looks for back-to-back victories at home for the first time since winning three straight from Nov. 2-14, the Lightning open their five-game road trip on a three-game losing streak.
Tampa Bay (10-18-10) lost 3-2 to Carolina on Saturday night after it was staked to a 2-0 lead on first-period goals from Ryan Craig and Vaclav Prospal. This was the second time in the past 11 games that Tampa Bay let a 2-0 first-period lead slip away. The Lightning lost 4-2 to Buffalo on Dec. 10 after holding a two-goal edge in the opening period.
"Everybody's frustrated," said Tampa Bay's Martin St. Louis. "But nobody's going to feel sorry for us. We've just got to keep plugging."
Tampa Bay has dropped 11 of its last 12 one-goal games.
Mike Smith, who made 25 saves on Saturday, is 1-3-0 with a 2.51 goals-against average in his career against Atlanta. In the Lightning's 3-2 overtime victory over the Thrashers on Oct. 21, Smith made 31 saves.
