Federer flattens Roddick to set up showdown with Nadal

ROGER FEDERER continued his domination of Andy Roddick with another crushing win over the American yesterday at the Tennis Masters Cup in Shanghai.

The world number one has responded well to his defeat to Fernando Gonzalez on Monday in his Red Group opener.

A convincing win over Nikolay Davydenko put him firmly back in contention and the Russian’s victory over Gonzalez earlier yesterday assured Federer a place in the semi-finals.
