All the seeds who played in Paris today advanced. Top seed Serena Williams had her work cut out for with Stefanie Voegele, who took the first set to a tiebreak. In the second set, however, Williams utilized her serve to take control and post a 7-6, 6-2 victory. She is now 42-0 in first rounds in the four major tournaments.
Sara Errani suffered yet another loss, going out in straight sets to Yaroslava Shvedova. Warsaw champion Alexandra Dulgheru went to three sets against Lucie Hradecka, but advanced to the second round. 2nd seed Caroline Wozniacki defeated Alla Kudryattseva 6-0, 6-3. And 4th seed Jelena Jankovic, dressed in sunny yellow, defeated Alicia Molik 6-0, 6-4.
Bethanie Mattek-Sands, who rolled her ankle when she was up a break in the third set of her third qualifying round, is now a lucky loser. Mattek-Sands was second in line to be a lucky loser; and the first in line wasn't feeling too well, so Mattek-Sands was given a place in the main draw when Peng Shuai withdrew from the tournament. She has received treatment for her ankle and will play Vania King. Peng withdrew from Stuttgart because of illness, but I don't know whether that is why she withdrew from the Open.
