Though they lost their serve three times in their first match since capturing the French Open, the top-seeded Hsieh and Peng offset that damage by converting on six of eight break points en route to a 6-2, 7-5 victory. They have now only failed to win their opener just once in 13 Grand Slams together, that happening here in 2009.
Next up for Hsieh and Peng are Yuliya Beygelzimer and Klaudia Jans-Ignacik. Joining them in the second round were No.15 seeds Liezel Huber and Lisa Raymond, who were 6-0, 7-5 victors over Yvonne Meusburger and Katarzyna Piter. The Americans won 14 of 17 points on their opponents' second serves in setting up a second round encounter with Shuko Aoyama and Renata Voracova.
A couple of notable unseeded winners were Flavia Pennetta and Samantha Stosur and Anastasia Pavlyuchenkova and Lucie Safarova. Pennetta and Stosur, who are teaming up for the second time, have each spent time as doubles World No.1.
Rain caused a couple of matches to either never take the court or be suspended, including No.7 seeds Raquel Kops-Jones and Abigail Spears, who will resume on Friday on serve in the first set against Naomi Broady and Eleni Daniilidou.
