Radwanska reaches another final; Kerber ousted in Sydney

Sydney, Australia – Top-seeded Agnieszka Radwanska won her semifinal matchup on Thursday, while No. 2 seed Angelique Kerber was upended at the Sydney International, a final Australian Open tune-up.

The world No. 4 Radwanska, who was last week's champion in Auckland, handled fourth-seeded Chinese slugger Li Na at Sydney Olympic Park Tennis Centre. Li was fresh off her season-opening title in Shenzhen in her native China, was last year's Sydney runner-up to Victoria Azarenka, and captured this event in 2011.

Radwanska saved 4-of-6 break-point opportunities and took advantage of five double faults from Li en route to a 6-3, 6-4 triumph.

The Wimbledon runner-up Radwanska has yet to drop a match this season and will be looking for her 12th career title when she takes on Slovak and fellow 23-year-old Dominika Cibulkova in Friday's final.

Cibulkova knocked off the left-handed German Kerber 6-2, 4-6, 6-3 to secure a spot in her seventh career final.

The diminutive Cibulkova is the first unseeded finalist in Sydney since Jelena Jankovic made a trek into the final here in 2007. Overall, she's just the fifth unseeded woman to reach the final since 1990, joining Jankovic, Jennifer Capriati, Venus Williams and Sam Stosur.

Cibulkova, who owns two career WTA titles, has dropped all three previous meetings with Radwanska.
