WELLINGTON, New Zealand (AP) -- Top-seeded Agnieszka Radwanska beat Russia's Elena Vesnina 6-3, 6-3 after a lengthy rain delay Thursday to advance to the ASB Classic semifinals.
The fourth-ranked Pole kept her composure after the players were forced off the court early in the second set, returning to close out her third straight-sets win of the tournament.
Radwanska was joined in the semifinals by the two other seeded players remaining in the draw. Third-seeded Yanina Wickmayer of Belgium beat countrywoman Kirsten Flipkens 6-3, 6-4 and eighth-seeded Mona Barthel of Germany beat Sweden's Johanna Larsson 6-2, 6-1.
American Jamie Hampton was playing Kiki Bertens of the Netherlands in the last quarterfinal later Thursday.
