Top men and women’s seeds continued their march at 2015 Miami Masters as many of men’s third-round and women’s fourth-round matches were completed. Djokovic and Serena cruised into their next rounds without much trouble as did Kei Nishikori, Milos Raonic, David Ferrer, David Goffin, Gilles Simon and Alexandr Dolgopolov. But Grigor Dimitrov was halted in his tracks by John Isner. In two notable upsets among women, Venus Williams came up with a great performance against the Dane Caroline Wozniacki and Spain’s Carla Suarez Navarro saw off Agnieszka Radwanska. Most other women’s seeds went through to the quarterfinals on Monday.
