Chongqing, March 14 -- Chinese Kuai Man denied teammate Sun Yingsha a third-straight title at the WTT Champions Chongqing tournament as she crushed the three-time Olympic champion 4-2in the women's singles quarterfinals on Saturday.

The 22-year-old Kuai played a very aggressive game from the beginning and overcame Sun 6-11, 11-7, 16-14, 11-7, 9-11, 11-2, according to Xinhua.

"This was unexpected," said Kuai. "I fought like an underdog and learned from the first set loss."The top-seeded Sun seemed to have lost concentration and trailed 1-10 before losing the lopsided sixth set.

In earlier rounds, second seed Wang Manyu and third seed Chen Xingtong, both of China, and third-seeded Zhu Yuling from Macao, China, had been ousted.
