Error-prone Djokovic survives scare, Serena rocks on

MELBOURNE (Reuters) - Novak Djokovic's grip on the Australian Open title looked shaky for a short spell on Sunday but the world number one finally shook off Gilles Simon in a four-and-a-half hour marathon to take his place in the quarter-finals.
Serena Williams, by contrast, booked a re-match of last year's title decider against Maria Sharapova by sweeping into the quarter-finals without having lost a set, and Roger Federer progressed almost as comfortably to bring the day to a close.

Hurtling around the arena on legs that have always looked too spindly to take the kind of punishment they regularly endure, the 31-year-old Frenchman absorbed Djokovic's power and timed his shots to perfection to hurl it back at the Serbian.
Djokovic has not won five titles at Melbourne Park without being able to negotiate a scrap, however, and despite a string of fluffed drop shots he reasserted his authority in the final set to reach the last eight for a 27th successive grand slam.
