Serena Williams is out of Miami Open after losing 6-7 (3-7) 6-1 6-2 to Russian 15th seed Svetlana Kuznetsov in the fourth round. It was the 34-year-old American’s joint earliest exit from the tournament, which she has won eight times. “The players come out and play me like they’ve never played before in their lives,” said Williams, who had not lost in Miami since 2012. She has now not won a tournament since August, when she claimed the 69th title of her career, in Cincinnati.
