Djokovic seals semi-final spot in Australia Open

Novak Djokovic has booked his place in the semi-finals of the Australian Open after securing a 6-1 4-6 6-1 6-4 victory over Tomas Berdych.

The top seed, who is chasing his third straight title in Melbourne, was outplayed in the second set but otherwise had things well under control to beat Berdych for the 10th time in a row.

Djokovic completed the victory in 2 hours and 31 minutes to set up a last-four clash with David Ferrer, who edged past fellow Spaniard Nicolas Almagro earlier in the day.
