Federer storms into semis
ROGER FEDERER toppled Argentine giant Juan Martin Del Potro 6-4 6-3 6-2 with some exquisite shot-making to reach the semi-finals of the Australian Open today.
The Swiss, chasing a 17th grand-slam crown and sixth in Melbourne, was never seriously threatened in their first meeting in a major since losing to Del Potro in the 2009 US Open final.
In scorching heat at the Rod Laver Arena, third seed Federer survived four break points before closing out the second set in his only wobble of an otherwise dominant display.
Normal service soon resumed, with Federer breaking the 11th-seeded Del Potro twice to motor through the third set, finally sealing the match with an imperious backhand winner.
Federer will play the winner of great rival Rafa Nadal and Czech seventh seed Tomas Berdych in the last four.
Federer said: "It was tough with the sun and the shade creeping across the court but I thought it was a really high quality match.
"Juan Martin is a great player and I knew how hard he could hit the ball so I tried to manoeuvre him round a little bit."
