Novak Djokovic continued his path to a potential Australian Open semi-final showdown with Roger Federer with a 6-1 7-5 7-6(6) third round victory over Italy'sAndreas Seppi on Friday.

The five-times Australian Open champion raced out to an opening 5-0 lead before Seppi, who beat Federer in four sets at the same stage last year, finally held his own serve though the Serb clinched the first set in 25 minutes in the next game.

The pair remained on serve throughout an evenly matched third set until Djokovic saved two set points in the tiebreak to set up a fourth round clash with 14th seeded Frenchman Gilles Simon.
