Sharapova was all business in seeing off American 17th seed Sloane Stephens 6-4 6-3 yesterday to set up a meeting with Serbian 18th seed Jelena Jankovic, who thrashed US hope Jamie Hampton 6-0 6-2, while double Australian Open champion Azarenka swamped 2010 French Open champion Francesca Schiavone 6-3 6-0.
Sharapova, who in beating Sara Errani in last year's final became the sixth player in the Open era to complete a full collection of Grand Slams, was rarely troubled by Stephens, Australian Open semi-finalist last January, the Floridian 20-year, gifting her a final break by hitting long on match point.
"We had a few freaky points, a few shanks. But, overall, I was happy with the way I focused most of the match," said the Russian, who joked her father "thinks I can beat Rafael Nadal on clay."
Self-critically she added: "This tournament I don't think I have played, you know, my best level, especially in the first few rounds. I thought I needed to step it up today. Yet it only gets tougher from here."
"It will be a tough one - I will just try to play my best tennis," said the 28-year-old.
