Azarenka begins in style
The defending Australian Open champion made light work of the German to set up a quarterfinal clash against qualifier Ksenia Pervak.
"I'm such a picky person that I probably never will be satisfied," Azarenka told reporters.
"That's a good thing because I have a lot more matches to play and I can always improve. But it was pretty good. I felt like the things that I've been working on are there. I'm getting into the competitive groove and I'm happy where I'm at right now,’’ she added.
Azarenka faces a challenge to her top ranking from world No 2 Maria Sharapova and No 3 Serena Williams when the Australian Open begins at Melbourne Park on January 14.
Williams will follow Azarenka on to Pat Rafter Arena on Thursday when she plays fellow countrywoman Sloane Stephens.
