Roger Federer flattened his close buddy Stanislas Wawrinka 6-1 6-3 6-3 to move menacingly into the Australian Open semi-finals on Tuesday, showing scant regard for sentimentality.
Defending champion Federer, the Melbourne second seed, overpowered Wawrinka in an hour and 47 minutes in the first grand slam quarter-final contested by two Swiss men.
Ripping winners from all angles, Federer tore through the first set in just 29 minutes before seizing complete control by adding the second with a looping backhand.
Master broke apprentice again at the start of the third before sealing victory with another vicious backhand, which was too hot for his dazed opponent to handle.
Federer, bidding to extend his record haul of grand slam titles to 17, faces either third seed Novak Djokovic or number six Tomas Berdych in the last four.
