China almost secured a gold medal in the Olympic women's singles table tennis event, with all three Chinese players packing into the semifinals on Thursday.

World number one Zhang Yining, world champion Guo Yue and Grand Slam veteran Wang Nan, after winning a team gold earlier this week, have maintained their strong winning momentum, steamrolling over all that confronted them.

Singapore's Li Jia Wei also reached the semifinals, showing no signs of slowing down in her drive for another medal. Li and her teammates won a silver in the teams, which was Singapore's first Olympic medal in 48 years.

Zhang edged out Feng Tianwei of Singapore 13-11, 12-14, 14-12, 12-10, 13-11 in their quarterfinal clash, which was the most closely-fought battle of the day. It was also the first time that the defending champion was really made to sweat for her victory.

"I was prepared for a tough match because I lost to Feng at the Asian Cup in March," Zhang told reporters after the match.

"Compared to the last time, I feel that she has improved a lot. You never know how far young players like Feng will go. She will have a great future," she added.

Zhang also said that the racket she usually used failed to pass the quality check-up for an uneven surface and that the backup one was a reason why she was having a hard time.

"I could not attack because of the rubber on the backup racket, which was glued three days ago," she complained.

Despite her loss, the 22-year-old Feng's confidence got a big boost. "In terms of technique and strategy, I'm no worse than Zhang," she said, adding she was certain about winning a medal at the next Olympic Games.

Another closely-fought match was played between two former Chinese players, Wang Chen of the United States and Li Jia Wei.

Li said she was satisfied at the 15-13, 11-6, 12-10, 13-15, 11-4 victory because "Wang is a former world champion and played very well today with furious attacks."

Wang announced her retirement earlier in the day, after reaching the quarterfinals with a hard-earned victory over the world's leading defensive player Kim Kyung-ah of South Korea.

"This is my last competition. I just wanted to try my best, and got every point that I could," Wang said. "Tactically, I had a chance to win, but I'm physically weaker and overtired after the match in the morning."

However, the 34-year-old was happy about the results, saying that "I reached the last eight, which is the best result the United States has ever had in Olympic table tennis."

Former Chinese player Wu Xue, now representing the Dominican Republic, posed little threat to China's Guo in their quarterfinal match, losing 11-5, 16-14, 13-11 and 11-5, while veteran Wang fought off the challenge from Tie Yana of Hong Kong, China, by 11-5, 11-4, 11-13, 11-2, 11-4.

"It's the last time I play for China, so I will try my best no matter how exhausted I am," the 30-year-old Wang said. The world's most decorated woman paddler said earlier this year that she would retire after the Beijing Olympics.

Zhang will play Li in the semifinals on Friday and the other match will be a sheer Chinese affair between Guo and Wang.

The men's singles competition produced a series of unexpected results on Thursday. However, the Chinese players, namely Wang Hao, Ma Lin and Wang Liqin, all reached the last eight with easy victories, to no one's surprise.

South Korea's defending champion Ryu Seung-min failed to reach the last 16 because of his loss to Ko Lai Chak of Hong Kong 7-11, 8-11, 6-11, 11-4, 11-5 and 10-12, the biggest upset of the day.

Belarussian Vladimir Samsonov, the highest-ranked non-Chinese, suffered a defeat in the 1/8 round, losing to 42-year-old Swedish veteran Jorgen Persson 11-7, 11-8, 9-11, 13-11, 7-11, 10-12 and 9-11.

European champion Timo Ball of Germany also lost to a lower-ranked South Korean Oh Sang Eun 9-11, 4-11, 9-11, 11-8 and 3-11.
