China's Peng Shuai Could Not Continue With Her Giant-Killing Run as She Was Stopped By Russia's Nadia Petrova

In the elite WTA tournament, China's Peng Shuai, 53rd ranked in the world, did not continue with her giant-killing run as she was stopped by Russia's 13th seed Nadia Petrova 6-7(5), 6-3, 6-2 in the quarterfinals.

Peng, who beat top seeds Jelena Jankovic and Maria Sharapova on her road to the last eight, broke Petrova's first serve for a 2-0 lead in the opening set, but Petrova broke back in the fourth game to level the match.

At 6-5, Petrova threatened to close up the set earlier while forcing a break point in the 10th set on Peng's serve, but the 23-year-old Chinese girl, who produced an impressive display of baseline work, held serve and won the following tiebreak at 7-5.

Peng seemed to have trouble in moving with her left leg, called medical timeout at 1-1 in the second set, which did not help.

The Russian broke in the seventh and ninth games to pull back one set at 6-3.

Petrova, physically in good shape after battling through second seed Serena Williams in the last round only 15 hours ago, had a much easier time of it in the final set.

"When she called a timeout, I thought I might have chance of winning. I told myself that I need to stay focused," said Petrova.

Her reward will be a semifinal against Russian Svetlana Kuznetsova.
