Australia’s Olivia Rogowska has defeated compatriot and defending champion Jelena Dokic in the second round of the Malaysian Open in Kuala Lumpur.

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

Her quarter-final opponent will be Eleni Daniilidou of Greece, who cruised past fourth-seeded Australian Jarmila Gajdosova 6-4 6-0.

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 completed her suspended first-round match by defeating Akgul Amanmuradova of Uzbekistan, setting up a second-round match against qualifier Karolina Pliskova, Kristyna’s twin.
