Auckland, New Zealand – World No. 4 Agnieszka Radwanska was taken to tiebreaks in both sets by unheralded American Jamie Hampton before edging her way into the final of the ASB Tennis Classic.

Top-seeded Radwanska had dropped only 10 games on her way to Friday's semifinal, sweeping her first three matches in straight sets, but was fully taxed by the 71st-ranked Hampton before winning 7-6 (4), 7-6 (3).

Poland's Radwanska will now face third-seeded former champion Yanina Wickmayer in Saturday's final. Wickmayer reached her third singles final in Auckland when she beat eighth-seeded German Mona Barthel 6-4, 1-6, 7-6 (3). – Sapa-AP
