Robson on song

Laura Robson continued her fine recent form by advancing to the last-eight of the Guangzhou International Open.

Robson, 18, who reached the fourth round of the US Open earlier this month, saw off Chinese second seed Jie Zheng in straight sets, with the Briton's clinical edge seeing her capitalise on five of her six break-point opportunities.

Robson will face another Chinese opponent in the quarter-finals in the form of seventh seed Shuai Peng after the home favourite breezed to a 6-2 6-1 win over qualifier Nudnida Luangnam.

Third seed Sorana Cirstea defeated wildcard Ying-Ying Duan 6-1 7-6 (7-0) to set up a quarter-final clash with French eighth seed Alize Cornet, who advanced when Olga Govortsova retired hurt after losing the first set of their contest 6-4.

Chanelle Scheepers beat Bojana Jovanovski 6-4 6-1 while her next opponent, Urszula Radwanska, was also a straight-sets winner as Luxembourg's Mandy Minella was dispatched 6-2 6-3.

Taiwan's Su-Wei Hsieh beat compatriot Kai-Chen Chang 6-0 6-3. France's Mathilde Johansson overcame a second-set wobble to triumph 6-2 4-6 7-5 over China's Saisai Zheng.
