Sharapova and Venus progress
Maria Sharapova and Venus Williams remained on course for an Australian Open third-round shoot-out after registering emphatic wins on Monday.
In an opening session free of shocks, Sharapova and Williams were the first women to advance after dropping just a solitary game between them in seeing off Olga Puchkova and Galina Voskoboeva respectively.
There was little Russian solidarity on show as the second seed enjoyed a 6-0 6-0 'double-bagel' against an opponent who gave a faultless impersonation of a rabbit trapped in the headlights on Rod Laver Arena.
The win moved Sharapova a step closer to a potential third-round shoot-out against five-time Wimbledon champion Venus Williams and also dispelled any doubts over the state of her collarbone which she injured shortly before Christmas.
Last year's beaten finalist said: "After a couple of close games I started to concentrate a bit better.
"I didn't want to focus on the fact I hadn't played a lot of matches but just focus on what was ahead of me and really be aggressive.
"Today was a good scoreline."
Although she didn't drop a game, Sharapova insisted there was still room for improvement.
"It's tough to feel completely satisfied," she said.
"You always want to improve on things and work on certain things that you feel will help you in the later rounds towards the end of the second week.
"But overall I was happy with the way I started considering I didn't play any matches coming in."
Sharapova may have been the first winner of the tournament but she was closely followed by Williams, who dropped just one game in brushing aside Galina Voskoboeva.
The American was pleased to have negotiated the first hurdle with the minimum of fuss.
She said: "It's nice to spend less time on court and not be in long sets.
"A win is a win no matter what the scoreline is, but it's nice when it's more routine."
There were also wins today for in-form fourth seed Agnieszka Radwanska, fifth seed Angelique Kerber, sixth seed Li Na and home favourite Sam Stosur.
Radwanska, the winner of the warm-up events in Auckland and Sydney, looked in danger of dropping her first set of 2013 when Australian wild card Bojana Bobusic served for the opener at 5-4 but the Pole upped her level and rattled off the next nine games to go through 7-5 6-0.
Li, the runner-up here in 2011, eased past Kazakhstan's Sesil Karatantcheva 6-1 6-3, Kerber had few problems in seeing off Elina Svitolina but Stosur was made to work harder by Chang Kai-Chen of Chinese Taipei.
Ninth seed Stosur has only got as far as the fourth round of her home grand slam - in 2006 and 2010 - and had her nervy moments once again before securing a 7-6 (7/3) 6-3 triumph.
Top seed and defending champion Victoria Azarenka and title favourite Serena Williams open their campaigns on Tuesday against Romanian opposition. Azarenka meets Monica Niculescu while Williams takes on Edina Gallovits-Hall.
