$ 0 0 Unruffled by a bomb scare that locked down the SonyOpen late on Tuesday, world number one Rafael Nadal brushed past Italy's Fabio Fognini 6-2 6-2 to join Novak Djokovic, Roger Federer and Andy Murray in the last eight Officials announced a suspicious package had been left near the main entrance to the sprawling tennis facility which was quickly locked down, keeping thousands of spectators from entering or leaving while Miami Dade police investigated. The Spaniard showed no signs of being alarmed by the bomb scare as he completed the win in 62 minutes. Nadal's next opponent is Canadian Milos Raonic, who beat Benjamin Becker 6-3 6-4. "He's a very dangerous opponent," added the Spaniard. "His serve is huge, one of the best without any doubt, and he's able to play very aggressive on the return because he doesn't feel a lot of pressure on his return because he knows that he's very safe with his serve."
