Djokovic impresses in Melbourne opener

Novak Djokovic defied sweltering conditions to ease into the second round of the Australian Open today.

Serbian Djokovic, who won the trophy here in Melbourne 12 months ago at the start of a remarkable year which also saw him emerge victorious at Wimbledon and the US Open, made a convincing start to his title defence against Paolo Lorenzi, winning 6-2 6-0 6-0 on Rod Laver Arena.
