Top-ranked Djokovic powers into Miami Open last 16

World number one Novak Djokovic advanced to the fourth round of the ATP and WTA Miami Open, defeating Portugal's 38th-ranked Joao Sousa 6-4, 6-1. Two-time defending champion Djokovic, trying to match Andre Agassi's record of six career Miami titles, needed only 78 minutes to win his 12th match in a row at the hardcourt event and 26th in his past 27 Miami starts. "That first set could have gone either way," Djokovic said.
