If Zheng Jie thought winning two Grand Slam events was tough, she now faces an even tougher job to do -- to claim her first ever Olympic title on home soil.
Zheng's latest success at Wimbledon has demonstrated that she is more than a doubles specialist.
In the best performance by a Chinese player at a grand slam to date, wildcard and 133rd ranked Zheng beat top seed Ana Ivanovic, 15th seed Agnes Szavay and 18th seed Nicole Vaidisova, bowing out to Serena Williams after a second set tiebreak in the semifinals.
The sensational run in particular boosted China's chances of landing tennis gold at the Games after a largely bleak 18-month run for China's leading women players.
"After the August Olympics I might put more efforts on the singles, but as for the Beijing Games, my focus is still on the doubles," said Zheng, who just turned 25 on July 5.
"Everybody wants more medals, but I think my partner Yan Zi and I appear more hopeful in the women's doubles and we have been preparing for it for a long time."
Zheng, who missed most of last year with an ankle injury, is a former Wimbledon and Australian Open doubles champion as well as an Asian Games doubles and singles winner.
Before the injury she had won 10 doubles titles with Yan and three singles titles but only added the Sydney doubles title after returning this season.
With long-time partner Yan, however, she is still considered the best chance of China retaining the Olympic women's doubles gold medal won by Sun Tiantian and Li Ting in Athens.
Zheng and Yan also had their first taste of the Olympics in Athens, but were sent packing in the quarterfinals.
China's hopes of success in Beijing had seemed real after the breakthrough of Chinese women largely inspired by Zheng in 2006, but a fragile left ankle ruled Zheng out for much of last season.
Deputy director of China's Tennis Administrative Center Gao Shenyang chose to see the different side of the coin, saying after Zheng's Wimbledon success that the injury has unexpectedly turned in Zheng's favor.
He said: "After recovering from the injury, Zheng has matured a lot and played with much clearer mind. For many times against higher ranked players in the tournament, she was just able to play cool."
Zheng's long-time injury in the left ankle aggravated in the French Open in 2007 when she suffered both early exits from the singles and doubles events.
