(CNN) -- Australian Open champion Novak Djokovic got his preparations for this year's opening grand slam back on track with a commanding straight sets win over Frenchman Paul-Henri Mathieu in Sydney.
Djokovic made sure he continued his preparations for next week's grand slam with an emphatic win.
Djokovic was beaten in his first match of the season in Brisbane, but made no mistake against world number 29 Mathieu, winning 6-1 6-2 in just 54 minutes.
The world number three secured two breaks of service in each set and was also confident on his own delivery for a morale-boosting win.
"I served well throughout most of the match," the Serbian told the ATP Tour Web site.
"I was more or less happy with my consistency thought the match. I wasn't really having a lot of ups and downs. It was one high level of the game, and really didn't give him any chance to think that he can come back."
Djokovic, a late entry for Sydney after his earlier setback, will now play Mario Ancic.
The Croatian upset Spanish seventh-seed Tommy Robredo 6-2 6-1, showing the form that had made him a top 10 player.
Jo-Wilfried Tsonga, beaten by Djokovic in last year's Australian Open final, also went through with a 6-4 6-1 win over Italian Simone Bolelli in his second round match.
Another seeded winner on Wednesday was No.4 David Nalbandian of Argentina, sweeping past Frenchman Michael Llodra 6-1 6-3.
Next up for Nalbandian will be a mouthwatering clash with four-time Sydney champion Lleyton Hewitt, a 7-5 6-4 winner over Janko Tipsarevic of Serbia.
"We haven't played for a while," said Hewitt. "It's another step up in class, though," added the former world number one who has been training hard for his home grand slam.
