Reports: former world number seven Vaidišová retires from tennis at 20

The Czech tennis player Nicole Vaidišová has retired at the age of 20, according to media reports. Vaidišová reached the semi-finals at two Grand Slam tournaments and in 2007 got as high as seventh in the world rankings. However, her career has been going downhill for some time and she is currently ranked 176th. One tennis website reported that Vaidišová, who is the girlfriend of Czech men’s number one Radek Štěpánek, was evidently tired of losing matches and had no desire to return to the court.
