Entering her third-round matchup today, Serena Williams knew who she was facing in Belgium’s Kirsten Flipkens, the same woman who ousted her sister Venus in the opening round of this tournament. Serena needn’t have worried.

After a convincing 6-1, 6-2 victory yesterday to advance to face the Belgian, it was more of the same from the American today who made short of work of Flipkens, winning 6-0 6-3 to advance to tomorrow’s quarter-final.

While she was confident of her performance today, “I think I played really well. I think I played really well,” Serena wasn’t afraid to admit that there are areas of her game which she can improve on.

“So I wasn’t really happy with the way I was returning,” the 31-year-old stated at her post-match press conference. “I made a lot of unforced errors on the return. I have been returning really well and I just wanted to hit more returns.”

With Flipkens now behind her, Serena Williams is now focusing on her quarter-final opponent Magdalena Rybarikova, whom she will square off against Friday evening after the Slovakian advanced after an undisclosed injury forced her third-round opponent Marion Bartoli to retire during their match on Thursday.

When asked if she ever played Rybarikova before, Serena curtly answered, “I don’t think I have. I’m pretty sure I haven’t.” Unfortunately, confusion set in as the American continued, “With me I never know. I have played so many players.”

It certainly isn’t a shock to suggest that Serena Williams is slated as the heavy favourite in her quarter-final matchup. Of course, with Serena’s uncertainty of any past competition with the 24-year-old may come a fair bit of uncertainty of how to deal with the native of Piestany, Slovakia.

Nevertheless, as ready as Magdalena Rybarikova should be ready for Friday evening, the same should be said for Serena Williams who may be in for a tougher fight that she initially planned for.
