Top seed Simona Halep cruised into the Guangzhou International Women's Open quarter-finals with a comprehensive 6-4 6-0 victory over Timea Babos.
Although broken twice in the opening set, Halep was able to put plenty of pressure on her opponent's serve and, after squandering five set points, she was eventually able to move ahead.
Babos' resolve quickly diminished in the second set as Halep moved through the gears, the Romanian taking all six games and only dropping eight points.
Halep will meet Denisa Allertova in the last eight after she beat Bojana Jovanovski 6-3 7-6 (7-5).
Third seed Sara Errani was involved in one of only two matches to go to three sets on Wednesday as she came from behind to beat Zhang Kai-lin.
Their clash included a remarkable 17 breaks of serve and Errani wasted two set points in the first before Zhang moved ahead, but the Italian quickly rallied and came through 6-7 (6-8) 6-4 6-2.
Zheng Saisais's straight-sets victory over Anett Kontaveit means Errani will face another Chinese opponent in the next round, the eighth seed winning 6-1 7-6 (13-11) in just under two hours.
The other match to go the distance was fourth seed Jelena Jankovic's battle with Francesca Schiavone, the former getting the decisive break in the deciding set to seal a 7-5 4-6 6-4 triumph.
Jankovic will meet fifth seed Svetlana Kuznetsova in the next round, the Russian rarely troubled as she trounced Urszula Radwanska 6-0 6-1 – including a streak of nine games in in a row at the start of the match.
Sixth seed and defending champion Monica Niculescu enjoyed a comfortable 6-3 6-2 win over Rebecca Peterson, while Yanina Wickmayer was also able to cruise into the last eight with a 6-3 6-4 success of Monica Puig.
