Novak Djokovic tested by Hewitt

Djokovic defeated the two-time grand slam champion, 6-1, 6-3, 4-6, 6-3 in almost three hours to set up a quarter-final with Spanish fifth seed David Ferrer on Wednesday.
The Serbian world number one was in command for the opening two sets before the fiercely competitive Australian veteran hit back, taking the match into a fourth set.But top seed Djokovic gradually regained control to serve out with two aces in his final game to clinch victory.
The Serb began brilliantly and broke Hewitt in his first five service games and won 18 of the opening 24 points.However, feisty Hewitt refused to give in and he began to make Djokovic play more shots, as he fought his way back to the cheers of the capacity home crowd at Rod Laver Arena."I have to give credit to Lleyton who never gives up, he's a great competitor and obviously made me play an extra shot and I made a couple of unforced errors," Djokovic said."He's very well known for that, in the last 10-15 years he's been playing consistently well on the men's tour and he's a great competitor and I have a lot of respect for him and wish him luck.""For two sets and 3-0 I was playing really well and then suddenly I stopped moving, and I give a lot of credit for that to Lleyton."
