China's Zheng shocks Radwanska

Rio de Janeiro - China's Zheng Saisai stunned jaded Polish fourth seed Agnieszka Radwanska at the Olympics on Saturday, carving out a 6-4, 7-5 win.

Zheng, the world number 63, made the most of a lacklustre performance from Radwanska who had to cross the Atlantic Ocean twice to get to Rio.

Radwanska had been playing at the Montreal WTA tournament last week but was stranded in the Canadian city when her connecting flight to Miami was cancelled due to a mechanical failure.

She flew to New York but was unable to make it to Florida due to adverse weather conditions, so decided to perform a quick trans-Atlantic dash and back again to preserve her Olympic dream.

Polish media reported that Radwanska jetted to Lisbon before flying to Rio, completing a marathon 14,000km trip.

It was the second top win of the day for China after national number one Zhang Shuai saved three match points to beat Swiss 12th seed Timea Bacsinszky 6-7 (4/7), 6-4, 7-6 (9/7).

Zhang next faces either Germany's Laura Siegemund or Bulgaria's Tsvetana Pironkova, while compatriot Zheng takes on Russia's Darya Kasatkina.
