On the women's side of the draw, Serena Williams bested Ekaterina Makarova in straight sets, 6-4, 6-0, and will now face the winner of the Maria Kirilenko versus Andrea Hlavackova match. It took Williams just 79 minutes to defeat Makarova, and Serena has now won every match so far in this year's Open in straight sets.
