Radwanska secures final spot

Agnieszka Radwanska remains on course for back-to-back titles after reaching final of the Sydney International.

Radwanska, who won the WTA crown in Auckland, overcame former champion Li Na 6-3 6-4 to continue her stunning start to 2013.

Top seed Radwanska will now face Dominika Cibulkova after the Slovakian edged out second seed Angelique Kerber.

Radwanska had needed seven match points before finally secure victory on the Ken Rosewall Arena

"It was kind of like a deja vu from the Auckland final. I had also I think seven, eight match points before I win this final, so very similar situation," she said.

Cibulkova recorded a shock win over Kerber, with the 23-year-old eventually coming through in three sets.

Cibulkova got off to a flying start and then held off Kerber's stirring fightback to win 6-2 4-6 6-3
