Atlanta looks to match a franchise-record, four-game win streak when it visits the surging Ottawa Senators.
"I thought we played really well defensively," Atlanta coach Bob Hartley said. "We didn't generate as many chances as we would have liked, but we still played hard and we still played smart."
Kovalchuk assisted on Robitaille's goal, giving him eight points -- including three goals -- during Atlanta's current three-game win streak. Kovalchuk, second in the NHL with 21 goals and 43 points, did not record a point in the previous three games as the Thrashers were shut out in three straight losses.
Directly before their three-game skid, the Thrashers had won four in a row for the second time this season to match a franchise record.
With Dany Heatley -- Atlanta's other star forward -- still out of the lineup, Marc Savard is on pace for the best season of his career. Savard has one goal and six assists in his last three games and is among the league leaders with 37 points.
Ottawa has rebounded from a disappointing November with a very strong December, losing just two of 13 games (7-2-4).
The Senators skated to their second straight tie Friday, 3-3 against visiting Pittsburgh.
"We didn't get off to a good start," White said. "We weren't working hard defensively. The start of the game was key. We battled hard but the bottom line is we didn't do enough to win."
