In first-round action completed on the day, second seed Tomas Berdych was beaten by Pablo Cuevas, going down 6-4 6-4.
Nadal also avoided joining world number five Tomas Berdych on the sidelines after the Czech, who won the rain-delayed Shenzhen Open on Monday, became the latest big name to fall in Beijing. “We have to travel a lot”.
Ferrer’s countryman Rafa Nadal also made his way through to the last eight with a 7-6(3) 6-4 win over Vasek Pospisil in the final match of the evening. The conditions are always very different, very hard, week by week here in China.
Nadal faced just one break point against Pospisil and managed to save it. He snatched the first set by claiming two mini-breaks in the first set and then claimed a single break of serve in the second. “It’s not easy to adjust”.
I want to go on holidays and say: “‘Look, I had a great year, I did everything I could, to go off the court feeling that I did all my effort, ‘” Muguruza said.
Croatia’s Ivo Karlovic had no problems with his serving, though, as he smashed down 19 aces on his way to a 7-5 7-6 (7/1) victory over Guillermo Garcia-Lopez of Spain.
Next up for the 33 year old is Chinese Taipei’s Yen-Hsun Lu, who continued to make the most of his wild card to upset Milos Raonic’s conqueror Viktor Troicki 6-4, 7-5.
American Sock cruised through his second-round match against Austria’s Andreas Haider-Maurer, winning 78 per cent of his service points in the 6-3 6-1 victory.
In the women’s draw, Agnieszka Radwanska of Poland, the fourth seed, advanced to the quarterfinals when Madison Keys retired from their third-round match with a thigh injury.
However, 13th seed Andrea Petkovic’s China Open is over after she was bundled out in three sets by Italy’s Sara Errani, 3-6, 6-3, 6-2.
Germany’s Angelique Kerber moved a step closer to qualifying for the WTA Finals with a dominant 6-2, 6-3 win over Caroline Wozniacki of Denmark.
