Laura Robson has been knocked out of the China Open after being defeated by Spain's Lourdes Dominguez Lino.
Seventh seed Li Na brushed aside Nadia Petrova 6-1 6-2 to reach the last 16 - her first victory over the Russian in seven matches. Li, who needs a big week to qualify for the season-ending WTA Championships, will play fellow Chinese Peng Shuai for a place in the last eight. Later on Tuesday, world number one Victoria Azarenka had no problems in seeing off Sabine Lisicki 6-4 6-2.
