It was a very good day for American women, with both Williams sisters coming back to win 3-set matches. The bigger surprise was the 4-6 7-6(3) 6-1 win by Venus Williams over pint-size powerhouse Camila Giorgi, since Venus had not reached the second week of a major since 2011 Wimbledon. The more disturbing match was Serena Williams win over Elina Svitolina because the World #1 started extremely sluggishly, losing the first set 6-4. Although she garnered a 4-0 lead in the second set, it was not easy, but more of a war of attrition. Svitolina is a good player and managed to win another two games before Serena became more engaged and swept the last 8 games, winning 4-6 6-2 6-0.
Amazingly, there are now 4 American women in the round of 16 and 3 of them are in the same quarter: Williams, Keys, and Madison Brengle. The top seed here is Aggie Radwanska who will face Venus, while the Madisons face off for the other quarterfinal slot.
Serena is on track for a blockbuster quarterfinal with Victoria Azarenka, provided that Serena gets past Garbine Muguruza, the same youngster who gave her her worst beating ever in a major at last year's French Open, and Vika beats last year's Australian Open finalist Dominika Cibulkova.
Other potential mouthwatering matches are Maria Sharapova versus Genie Bouchard and Simona Halep against Ekaterina Makarova.
