Andy Murray reach quarters in Miami
Two-time defending champion Novak Djokovic crashed out in the fourth round of the Miami Masters Tuesday while last year's runner-up Andy Murray eased through to the quarter-finals in straight sets.
World number one Djokovic was stunned 6-2, 6-4 by German 15th seed Tommy Haas but US Open winner Murray had no such difficulties, breezing past Italy's Andreas Seppi by the same score in the $8.5 million ATP and WTA hardcourt event.
The Serb lost for just the second time this season, never getting to grips with Haas, who kept Djokovic off his game with a number of skillful shots.
Haas, who turns 35 next week, advances to the last eight where he will face Frenchman Gilles Simon who outlasted Djokovic's countryman Janko Tipsarevic 5-7, 6-2, 6-2.
Haas hit seven forehand winners and won 76 percent of his first-serve points, snapping Djokovic's 14 match-winning streak in Miami.
Haas easily won the first set then clinched victory on his second match point with a forehand winner to the open court, ending the 80 minute match.
Djokovic, who had won this event three times (2007, 2011, 2012), had one double fault and won just 54 percent of his second serves.
This is the first time since 1999 Haas has beaten a world number one. He defeated Andre Agassi in three sets at the Grand Slam Cup for his only other win over a world No. 1 in 15 contests.
