BEIJING, Oct 4: Germany�s Angelique Kerber suffered a shock defeat to China�s Shuai Zhang on Thursday to crash out of the China Open in Beijing.
Third-seeded Kerber was beaten 6-2, 2-6, 6-0 as the unseeded Zhang delivered the upset of the competition so far, reports Efe news.
The local favourite was superior in every category, hitting more winners, more aces and more breakpoints than three-time Grand Slam winner Kerber.
Zhang�s emphatic victory means she advances to the last eight, where she will face Japan�s Naomi Osaka.
Osaka eased past Germany�s Julia Goerges in straight sets to advance to the quarterfinals.
Osaka � the reigning US Open champion, crushed the 10th-seeded German 6-1, 6-2.
After a slow start, during which Osaka saved a break point and exchanged several deuce points with Goerges, the Japanese player raced into a 5-0 lead in the first set.
The second was similarly challenging for the German, who was never able to trouble the world number six.
Osaka moves on to the quarterfinals, where she will face either Angelique Kerber or Shuai Zhang.
Former champion and No. 2 seed Caroline Wozniacki returned to the quarterfinals as she defeated Anett Kontaveit 7-5, 6-4.
The victory was two-fold for the Australian Open champion, as it also officially qualified her for the BNP Paribas WTA Finals Singapore presented by SC Global.
The No. 2 seed was the second player to qualify for Singapore on Thursday, as Petra Kvitova secured a spot thanks to Katerina Siniakova�s victory over Kiki Bertens.
An ultra-consistent Wozniacki outlasted the upset bid by the Dongfeng Motor Wuhan Open runner-up, as Kontaveit was unable to score her third Top 10 victory on Chinese soil in two weeks. � Agencies
