Top seed Maria Sharapova cruised into the third round of the Australian Open on Thursday with a straightforward victory over Anastassia Rodionova.

US Open champion Sharapova was taken to three long sets by Camille Pin in blistering conditions on Tuesday but had no such problems against her countrywoman, romping home 6-0 6-3 in just 58 minutes to set up a meeting with 30th seed Tathiana Garbin.

The Italian earlier beat Renata Voracova of the Czech Republic 6-1 7-5.
