Agnieszka Radwanska a comeback winner at Mercury Insurance Open
Agnieszka Radwanska, the runner-up at the Mercury Insurance Open in Carlsbad last year, survived a listless and luckless first set and became the first semifinalist in this year's tournament. Radwanska, seeded third, recovered from mistakes and mishits to beat eighth-seeded Daniela Hantuchova of Slovakia, 0-6, 6-4, 6-4, Friday.
Hantuchova and Radwanska often play doubles together and they won together this year in Miami. Radwanska, 22, of Poland, will play the winner of Friday's second quarterfinal, between American Sloane Stephens and second-seeded Andrea Petkovic of Germany.
