NOVAK Djokovic's bid to become the first man to take three consecutive Australian Open singles crowns is off and running after a straight-sets win over Frenchman Paul-Henry Mathieu 6-2, 6-4, 7-5.
The Serb will now take on big-serving American Ryan Harrison who took four sets to defeat Colombian Santiago Giraldo 2-6 6-4 7-5 6-4.
The world No.1 said he was pleased with his rhythm in his first outing.
"There are some few adjustments that I need to make and get a little bit sharper on the court," Djokovic said.
"But, you know, it's expected in the first match you're still not, you know, being a 100% on the court. You're trying to, but it's going to get better with matches that I play."
Djokovic said he was looking forward to playing Harrison and knew what to expect.
"He's one of these up-andcoming young talents who has been playing well on the tour for the last few years," he said.
"He has a big serve which he likes to use and big forehand.
"I played him few times before on different surfaces. I know what it takes to win that match."
