Serena sent crashing by Russian Petrova

Serena Williams shows her anguish after losing to Nadia Petrova in the China Open in Beijing.
World number one-elect Serena Williams has crashed out of the China Open, beaten in three sets by Russian Nadia Petrova just two days after reclaiming the top position.

Second seed Williams battled back several times but was unable to overcome the 13th seed, who reached the quarterfinals 6-4 3-6 7-6 in Beijing. The 28-year-old Williams looked lethargic in the first set, with her ground strokes sailing long and her serve broken twice to hand her 27-year-old opponent the early lead. But the American bounced back in the second, dictating play from the back oif the court to gain a break late in the set and even the match. In the deciding third set, Williams missed a golden opportunity to pull ahead at 4-4, blowing three break points on Petrova’s serve. However, she cranked up her serve to send it to a tiebreak.
