ATLANTA -- Ilya Kovalchuk couldn't let Dany Heatley, his friend and former teammate, have all the fun.
Kovalchuk scored a career-high four goals -- all in a row -- and the Atlanta Thrashers rallied from an early deficit to beat the Tampa Bay Lightning 5-2 Friday night, sending the defending Stanley Cup champions to their sixth straight loss.
"Yeah, Dany scored four goals earlier for Ottawa," Kovalchuk said, "so I wanted to do the same thing."
After Atlanta fell behind 2-0 late in the first period, Kovalchuk cut Tampa Bay's lead in half with 1:49 remaining. He then scored all three goals of the second period to notch his fourth career hat trick and give the Thrashers a 4-2 advantage.
Marian Hossa, acquired from Ottawa on Aug. 23 when Thrashers general manager Don Waddell granted Heatley's request for a trade, added a short-handed goal with 6:29 remaining and helped set up Kovalchuk's first. Marc Savard had three assists, and Niclas Havelid had two for Atlanta, which won two straight for the first time in 34 days.
Heatley scored four consecutive goals in Ottawa's 8-0 victory over Toronto on Oct. 29. Kovalchuk, the No. 1 pick in the 2001 draft, and Heatley, the second overall pick the year before, rank 1-2 on Atlanta's career scoring list.
"The most important thing is for us to win," Kovalchuk said. "We've got a really good chance to make the playoffs this year, so that's the biggest challenge for us."
Improving to 3-1-1 in their last five games, the Thrashers took the lead on the second of Kovalchuk's three power-play goals at 14:02 of the second. He stood in the slot with a defender between him and goaltender John Grahame and used a backhanded redirect on Havelid's slap shot from outside the top of the left circle.
Lightning coach John Tortorella pulled Grahame after the three-goal second period, and Gerald Coleman made his NHL debut.
Hossa scored after taking Andy Sutton's long pass inside the Atlanta blue line and beating Coleman at the right post.
Grahame saved 19 of 23 shots, including a glove stop on Savard's wrister near the left side of the crease, and fell to 5-8-1. The Thrashers were 1:22 into a two-man disadvantage when Kovalchuk scored his final goal.
"He's a pretty dangerous player on the power play," Tampa Bay forward Martin St. Louis said. "He finds a way to get open."
Kovalchuk, who tied Calgary's Jarome Iginla and Columbus' Rick Nash with an NHL-high 41 goals in 2003-04, was at the bottom of the left circle when he took Peter Bondra's pass and fired the puck between Grahame's legs to make it 4-2 at 19:43 of the second period.
"Kovalchuk -- he was worth the price of admission," Atlanta coach Bob Hartley said. "It's nice to see. Let's remember that he missed training camp. The history of guys in the NHL missing camp is never an easy start."
Tampa Bay has lost two straight to the Thrashers. But the Lightning's last victory was Oct. 29 in Atlanta.
"It's definitely frustrating," Grahame said. "We're doing everything we can to get out of it. We had a two-goal lead, but they were able to fight back."
Dan Boyle's slashing penalty wiped out Brad Richards' goal with 18:26 remaining that would have cut Tampa Bay's deficit to 4-3.
Atlanta's Andy Berkhoel made 34 saves.
Vaclav Prospal's slap shot from inside the blue line and near the left boards gave Tampa the lead with 6:36 left in the first.
The Lightning went ahead 2-0 when Ruslan Fedotenko took his own rebound and easily beat Berkhoel by faking a wrister in the slot and then scoring wide of the goalie's stick at 16:12. Prospal earned an assist on Fedotenko's third of the season.
Kovalchuk, who has nine goals this season, made it 2-1 just two minutes later with a slap shot from the top of the slot. He tied it 12:33 into the second.
- The only other Atlanta player with a four-goal game was Pascal Rheaume, who did it Jan. 19, 2002, at Florida. Kovalchuk had a goal and four assists in that contest.
- Bondra played in his 1,000th NHL game.
- Cory Sarich gave the Thrashers a two-man advantage in the second when he pushed Slava Kozlov and drew a boarding penalty.
