Kuala Lumpur, Malaysia, 2 March 2012 | AFP

Olivia Rogowska defeated fellow Australian and defending champion Jelena Dokic in the second round of the WTA’s Malaysian Open in Kuala Lumpur.

Rogowska needed slightly over two hours to oust the seventh-seeded Dokic 3-6 6-4 7-6 (2) at the Bukit Kiara Equestrian and Country Resort on Thursday.

“It was one of those frustrating days where I couldn’t play my best tennis,” Dokic said.

“It was a game I should have won easily.”

A delighted Rogowska will now face Eleni Daniilidou, who upset Jarmila Gajdosova of Australia 6-4, 6-0 in just over one hour for a place in the quarterfinals.

Meanwhile, second seed and former world number one Jelena Jankovic crushed Jill Craybas of the US 6-2 6-0 to set up a meeting with sixth seed Ayumi Morita, who survived a scare from fellow Japanese Misaki Doi before prevailing 7-6(6) 6-2.

Third-seeded Peng Shuai of China came from a set down to eliminate the Czech Republic’s Kristyna Pliskova 2-6 6-1 6-4. She will play fifth-seeded Croat Petra Martic in the quarters.

Top-seeded Agnieszka Radwanska of Poland had to play two matches, completing her suspended first-round match by defeating Akgul Amanmuradova of Uzbekistan then downing qualifier Karolina Pliskova, Kristyna’s twin, 6-4 6-4.

“Playing two matches (in one day) is bad, especially under these conditions. The weather really hasn’t been helping the progress of the tournament,” said Radwanska, who won the recent Dubai tournament.

She will meet Taiwanese qualifier Su-Wei Hsieh Friday for a berth in the semi-finals.

Rain forced her Tuesday match against Amanmuradova to be postponed and it was then called off on Wednesday with the score at 6-2 3-3.

When play resumed on Thursday, Radwanska was fired up to finish and took just 20 minutes to close out the match.
