BEIJING, China - Former champion and No.2 seed Caroline Wozniacki retured to the quarterfinals at the China Open on Thursday, 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.
Kontaveit totaled 55 unforced errors in the match to just 34 winners, which helped Wozniacki break serve six times.
Though the Estonian came from a break down in the second set, and had a break point at 4-4 which would've seen her serve for the set, she was unable to convert on that chance and dropped serve to love in the last game.
In the opening set, it was Kontaveit who break serve to begin the match, but Wozniacki hit back immediately to restore parity.
After the set went with serve, it was the Dane who earned the opportunity to serve for the set after again winning Kontaveit's serve in the eighth game.
The World No.21 nonetheless denied her the opener with a second break, and drew level thanks to a mammoth 10th game where she saved four set points over 10 deuces.
However, Wozniacki reasserted herself with a love hold, and came from 30-0 down to seal the set with a third break as Kontaveit fought for a tiebreak.
