For Andy Murray 2012 marked a golden milestone, for Novak Djokovic the year was an emphatic reminder of his status as the world's best male player, and for Roger Federer and his army of fans it was proof that the old master's magic still sparkles.
Serena Williams used the second half of the year to demonstrate that she continues to be head and shoulders above her rivals in the women's game, whatever the rankings suggest.
Of the sport's marquee names, only Rafa Nadal will reflect on the past year with regret after six months out with a knee injury, and all eyes will be studying the 11-times grand-slam winner's form once the new season swings into action.

"Considering the circumstances that I had to face on and off the court, expectations, all these things, I believe that this year has been even more successful for me," Djokovic, who won three major titles in 2011, said after beating Federer to
