The defending Australian Open champions have advanced to the second round of this year's tournament. No surprise there, as there haven't been any major upsets in the opening round just yet.
Djokovic cruised into the second round after a 6-2, 6-0, 6-0 victory in which the third set was 10 minutes shorter than the 33-minute second set.
Clijsters first-round match wasn't a breeze like Djokovic's, but she did win 7-5, 6-1 against Maria Joao Koehler. The match took an hour and eight minutes.
Then there's Petra Kvitova. The Czech player started making headlines last year when she ousted Sam Stosur in the third round before making it to the final eight. A year later, Kvitova is the tournament's No. 2 seed and breezed through her first match 6-2, 6-0.
From the Australian Open's official site:
"It was [a] surprise for me what I did last year, nobody knows that I could be No.2 in the world," she said.
"Everybody [is] saying soon I'll be No.1 in the WTA ranking, but you never know."
No. 4 seeded Maria Sharapova also won easily in a 58-minute 6-0, 6-1 victory over Gisela Dulko.
