KRAKOW, Poland (AP) - Agnieszka Radwanska of Poland has dismissed Croat coach Borna Vikic, three days after winning the Sony Ericsson Open.

Vikic had been coaching the fourth-ranked Radwanska and her sister Urszula since January on a trial basis. Radwanska said Tuesday that "he did not pass.''

She didn't say who will replace him.

On Saturday, Radwanska defeated Maria Sharapova 7-5, 6-4 in the Sony Ericsson Open final in Key Biscane, Fla.
