Federer set for semi-final showdown against Djokovic

Defending champion Roger Federer advanced to a semi-final showdown against Novak Djokovic with a straight-sets win against 12th seed James Blake.

The world number one remained composed during key points at the end of each set, though Blake won each of his three break points and made Federer work much harder than the scoreline of 7-5 7-6 (7/5) 6-4 would suggest.
