Having wound back the clock seven years, the street fighter in Lleyton Hewitt is vowing to continue punching above his weight in today's Australian Open showdown with champion of the world Novak Djokovic.
Hewitt is a raging underdog to knock out the powerhouse Serb, but has promised to come out swinging after rising from the canvas to spectacularly revive his flagging career at Melbourne Park.
After just one ATP match in four months, the battered veteran has slugged it out for more than nine hours to reach the second week of the Open with an improbable series of wins over Cedrik-Marcel Stebe, Andy Roddick and Milos Raonic.
Hewitt's against-the-odds triumphs over Roddick and Raonic were his first back-to-back grand slam successes over top-25 rivals since his glorious run to the 2005 Open final.
"A couple of months ago, I didn't know if I'd be able to play," Hewitt said.
