Djokovic out, but still looking at No. 2 ranking

Question

Having lost in the quarter-finals of the 2010 Australian Open, defeated by a combination of Jo-Wilfried Tsonga and illness, third ranked Novak Djokovic could still move up to world No. 2 at the end of the tournament. What needs to happen? Britain’s Grand Slam title drought needs to stretch another tournament. Djokovic will be the new world No. 2 as long as Andy Murray doesn’t win the title.
