For the third time in his career, Serbia's tennis star Novak Djokovic is today officially back at number two in the world rankings, ahead of Roger Federer.
Djokovic beat the world number one Rafael Nadal in yesterday's final of the Indian Wells tournament in California to continue his perfect start to the season with 18-straight victories, no defeats and three tournament wins including the Australian Open.
Djokovic beat Federer for the third time this year in the semi-finals at Indian Wells.
The biggest mover was the former world No.4 Juan Martin Del Potro. The 2009 US Open champion who had wrist surgery last year, jumped 39 spots to 51 after reaching the Indian Wells semi-finals.
