BEIJING - Former China Open champion Agnieszka Radwanska said Saturday she would aim to emulate her 2011 success, brushing aside concerns over pressure on the opening day of the tournament. The 24-year-old is up against a strong women's field in China, including Serena Williams, and Victoria Azarenka. But Radwanska said she was relaxed despite the tough competition, particularly as she had already booked her place in the end-of-season grand finale, next month's WTA Championships in Istanbul, which features the top eight women's players. I'm always very, very happy that I still can be one of the top seeds here," she told reporters in Beijing. "It's never easy here, so I am just really trying not to think about any pressure, especially that I made the qualifying already for Istanbul." –AFP
