MASON, Ohio -- There were two early upsets on the women's side in first round action of the Western & Southern Open, a U.S. Open tuneup.
Australian qualifier Anastasia Rodionova, ranked 139th, beat No. 42 Polona Hercog 6-0, 6-0, while No. 101 Chanelle Scheepers, a qualifier from South Africa, eliminated 39th-ranked Canadian Rebecca Marino 7-5, 6-2.
Svetlana Kuznetsova became the first seeded woman to advance without a bye. The 14th-seeded Russian beat American qualifier Jill Craybas 6-3, 6-4. Ninth-seeded Andrea Petkovic lost the first set and survived a second-set tiebreaker to pull out a 5-7, 7-6 (5) 6-2 win over Slovakian Jamila Gajdosova, and Ana Ivanovic of Serbia rolled to a 6-0, 6-2 win over qualifier Alexa Glatch of the United States.
Petkovic felt as if she almost didn't deserve to win the grueling match that lasted 2 hours, 52 minutes.
"I feel terrible," she said. "I feel awful, really, because (Gajdosova) was playing incredible. She was just hitting winners all over. I don't know how long we played, and I felt like I was in the defense all the time. That's not a good feeling, especially for a player like me who likes to be the dominant one, so I just felt terrible all the time. I don't know how I pulled it out, but I'm thrilled that I did."
Ivanovic needed just 26 minutes to win her first set and exactly one hour to finish her match. The former French Open champion hoped for a quick start, she said.
"It was very important, especially knowing she had a couple of matches under her belt," said the 17th-ranked Ivanovic, forced by a left foot injure to retire while playing eventual champion Kim Clijsters in last year's semifinals. "I had never seen her before, so it was like a new match for me."
Ukraine's Alona Bondarenko defeated Japan's Ayumi Morita 6-2, 4-6, 6-2; Israel's Shahar Peer beat Germany's Sabine Lisicki 6-4, 7-6 (4); Czech qualifier Petra Cetkovska defeated Spain's Anabel Medina Garrigues 2-6, 6-2, 6-2, and Italy's Sara Errani beat U.S. qualifier Sloane Stephens 6-1, 7-5.
Russia's Ekaterina Makarova eliminated Spain's Maria Jose Martinez Sanchez 7-5, 6-3, China's Jie Zheng needed three sets to get past Germany's Julia Goerges 6-2, 1-6, 6-4, qualifier Petra Martic of Croatia pulled away from Russian Elena Vesnina for a 3-6, 7-6 (5), 6-0 win, and Lucie Safarova beat Klara Zakopalova 6-2, 6-2 in an all-Czech match.
Sweden's Sofia Arvidsson, who lost in qualifying but received a berth when Japan's Kimiko Date-Krumm withdrew with a left hand injury, squeezed into the second round with a 0-6, 7-6 (4), 6-3 win over qualifying Romanian Monica Niculescu.
