Slovakian third seed Cibulkova shook off the memory of four prior defeats against Radwanska, including a 6-0, 6-0 thrashing in the final at Sydney in January, to claim a third career WTA title.

She broke world number four Radwanska for a 5-4 lead in the third set, then clawed through a final game lasting more than 10 minutes to seal the triumph on her fifth match point.
