Andy is such a boss.
When you think about it, he has a good record of knackering the most physical players in the sport.
USO 2008 vs Rafa, had him bent over clutching his knees whilst gasping for breath after a huge rally to earn match point.
USO 2012 vs Novak - Djokovic absolutely ****** by the end of that 5th set, could barely move.
Miami 2013 vs Ferrer - physically collapsed from cramp.
There's so little between the four of them in terms of endurance, but does Andy just edge it?
