Roger Federer Reach the Australian Open semi-finals and just away with two wins of a record-equalling 14th Grand Slam title.

Roger Federer destroyed the 20year old world number six to make his 19th consecutive Grand Slam semi, where he will meet old rival Andy Roddick.

After beating Juan Martin 6-3 6-0 6-0 Roger Federer said I didn't expect a result like this. This is not usual "I don't think Juan Martin was at his very best tonight, otherwise it would have been much closer."

Federer will be aiming for his 16th win against Roddick in the semi-finals
