Tennis: Djokovic starts well at Australian Open

World No 1 and defending champion Novak Djokovic marched imperiously into the second round of the Australian Open with a dominant 6-3 6-2 6-4 victory over Chung Hyeon today.

The 28-year-old Serb looked as untroubled by the Melbourne heat as he was by the South Korean teenager in the 115-minute contest, charging around Rod Laver Arena and rattling off 40 winners.

World No 51 Chung showed he had some impressive weapons at his disposal, particularly in the opening set, but was not always able to convert his best shots into points.

The 19-year-old stalled Djokovic's progress in an absorbing fifth match of the second set, holding serve after eight deuces, but the five-time champion soon advanced to a second round date with either French teenager Quentin Halys or Ivan Dodig.
