Federer, Nadal set up Miami clash

Rafael Nadal and Roger Federer will do battle on an American court for the first time in six years tomorrow after the great rivals set up a semi-final showdown at the Sony Ericsson Open in Miami.

Federer’s quarter-final opponent Gilles Simon retired from their match due to a neck injury, when the Frenchman trailed 3-0 in the first set, allowing the world number three to conserve his energy.
