Djokovic justifies favourite tag

Novak Djokovic showed why he is the hot favourite to win the US Open title with a rock-solid performance to beat wily Nikolay Davydenko 6-3 6-4 6-2 in the third round of the tournament.

It was the sort of match that could have tripped up the pre-2011 Djokovic but, although it was not easy for the world number one, he never looked in any danger.
