Agnieszka Radwanska will no longer be coached by Martina Navratilova, the world No. 9 announced in a statement.
The two began working together this past off-season, with Radwanska bringing on the 18-time Grand Slam singles champion in an effort to help win her first major title. But Radwanska has struggled this season, losing in the fourth round of the Australian Open and reaching just one semifinal, that at her hometown tournament in Poland.
