Martina Navratilova's brief stint as coach of 2012 Wimbledon runner-up Agnieszka Radwanska is finished.
Navratilova, who won 18 Grand Slam singles titles as a player, and Poland's Radwanska, who is currently ranked No. 9, issued statements Friday to announce the parting.
They announced in December that they would work together.
Radwanska is only 13-11 this season, including a first-round loss Wednesday in a clay-court tournament at Stuttgart, Germany.
A statement posted to Radwanska's Twitter account thanks Navratilova "for her time and efforts over these last few months" and calls it a "great experience to work with one of the all time greats.
