The shock fourth round exit of world number 1 and defending champion, Novak Djokovic at the hands of Tommy Haas as opened up the draw at the 2013 Sony Tennis Miami Masters.
Djokovic was taken out in straight sets by the 34 year old Haas and the German will now face 11th seed Gilles Simon in quarter finals. Should Haas win that match tonight, he will meet either 3rd seed David Ferrer or unseeded Jurgen Melzer in the semi finals. Meltzer and Ferrer also play their quarter final match tonight.
Andy Murray, world number three and 2nd seed this week in Miami, is still in the draw though, he so far as not dropped a set and came through his 4th round with Seppi very comfortably. He next faces 9th seed Marin Cilic which should be a tougher contest for Murray. Though the Murray Cilic Head to head currently stands at 7-1 in Murray’s favour.
The winner of Murray v Cilic will play the winner of the last quarter final between 8th seed Richard Gasquet and 4th seed Tomas Berdych. These two quarter final matches will be played on Thursday.
