( CNN ) -- World No . 1 Caroline Wozniacki began her latest bid for a first grand slam title with a 6-2 6-1 win over Anastasia Rodionova on Monday , joining last year 's finalists Kim Clijsters and Li Na in the second round of the Australian Open . Top seed Wozniacki looked in good shape as she wrapped up victory against the Russia-born Australian in 76 minutes , but the Dane admitted she was worried about a wrist injury she suffered during last week 's quarterfinal defeat at the Sydney International . `` I was a bit nervous before the match . I did n't know exactly what to expect . But it feels better , '' the 21-year-old told the WTA Tour website . `` I 'm very happy about the way I felt out there today . I got into the rhythm as the match went on tonight . '' Who will be the 2012 Australian Open victors ? Wozniacki will next play Georgia 's 83rd-ranked Anna Tatishvili , who beat Australia 's Ashleigh Barty 6-2 7-6 ( 7-4 ) . Former No . 1 Clijsters made a strong start to the defense of her crown with a 7-5 6-1 defeat of Portuguese qualifier Maria Joao Koehler . The Belgian 11th seed , who will play France 's world No . 98 Stephanie Foretz Gacon in the last 64 , showed little sign of the hip injury which forced her out of the Brisbane International 10 days ago . `` I wanted to go out there and I wanted to start playing , '' the 28-year-old told the tournament 's official website . `` I 've had that ever since we came to Australia . `` I had a good off-season where we worked obviously to try to be in good shape for Australia , then you want to put that to the test and play those matches again . '' Clijsters is on course for a fourth-round rematch with Chinese fifth seed Li , who eased through by beating Kazakhstan 's world No . 40 Ksenia Pervak 6-3 6-1 . Li , who became Asia 's first grand slam singles champion with her French Open triumph last year , struggled to handle the intense heat on court but emerged victorious to set up a clash with Australia 's 168th-ranked 20-year-old Olivia Rogowska . `` I was feeling at end of the first set really hot on the court. , '' she said . `` Also I was feeling no air . I could n't breathe . '' Third seed Victoria Azarenka of Belarus is through after an impressive 6-1 6-0 victory over Heather Watson of Britain in the opening match of the tournament . The victory continued Azarenka 's fine form coming into the tournament , having beaten Li in the final of the Sydney International on Friday . Her next opponent is Australia 's Casey Dellacqua , who beat Serbia 's Bojana Jovanovski 6-3 6-2 . Eighth seed Agnieszka Radwanska , a quarterfinalist in 2011 , came from behind to eliminate American Bethanie Mattek-Sands . The Pole 's reward for a 6-7 ( 10-12 ) 6-4 6-2 success is a match with Argentine qualifier Paula Ormaechea , who claimed the first WTA Tour level match win of her career by beating 50th-ranked Romanian Simona Halep 6-1 3-6 7-5 . Italian 10th seed Francesca Schiavone also booked her place in the next round . The 2010 French Open champion disposed of Spain 's world No . 72 Laura Pous-Tio 6-1 6-3 , and will next play Romina Oprandi . But their compatriot Flavia Pennetta made a shock early exit as the 19th seed lost 6-3 1-6 6-2 against Russian qualifier Nina Bratchikova . China 's 16th seed Peng Shuai is safely through thanks to a 6-3 6-4 win against world No . 120 Aravane Rezai . Peng will next play the Czech Republic 's Iveta Benesova , who beat Rezai 's fellow Frenchwoman Mathilde Johansson 6-3 2-6 6-4 . Former world No . 1 and 13th seed Jelena Jankovic progressed with a 6-2 6-0 demolition of Laura Robson , who was one of five British players to be eliminated in the men 's and women 's draws . American Christina McHale earned a surprise 6-2 6-4 win over Czech 24th seed and 2007 Australian Open quarterfinal Lucie Safarova . Belgian 28th seed Yanina Wickmayer , who won the the Hobart International title last week , lost 7-5 6-2 to Kazakhstan 's 62nd-ranked Galina Voskoboeva . Spanish 26th seed Anabel Medina Garrigues went through 6-3 6-3 against Czech Eva Birnerova , while Slovakian 20th seed Daniela Hantuchova recovering from dropping the opening set to Uzbekistan-born American Varvara Lepchenko to win 4-6 6-3 6-2 .
