MIAMI, March 29: World number one and three-time defending champion Serena Williams and second-ranked Andy Murray both crashed out of the ATP and WTA Miami Open on a day filled with upsets.
Williams and Murray each made 55 unforced errors, fading in the third set when it mattered most.
Williams� struggles prompted questions about her fitness and movement, irking the 21-time Grand Slam champion.
The 34-year-old American was seeking her ninth Miami crown but instead matched her earliest-ever exit from 2000 with a fourth-round departure.
�It�s obviously disappointing, but I have won here a lot, so it�s OK,� Williams said.
Also ousted were world number two Agnieszka Radwanska of Poland, eliminated by 20th-ranked Swiss Timea Bacsinszky 2-6, 6-4, 6-2, and Spanish fourth seed Garbine Muguruza, who fell 7-6 (8/6), 7-6 (7/4) to 13th seed Victoria Azarenka of Belarus.
Only two of the top 12 seeds � number two Angelique Kerber and number five Simona Halep � remain on the women�s side. Top-ranked Novak Djokovic is the last top-five man remaining and only three of the men�s top eight made the last 16.
Two-time Grand Slam champion Murray failed in his bid for a third Miami trophy and fourth final in five seasons. � Agencies
