Fourth-seed Kei Nishikori wasted no time in advancing to the fourth round of the Miami Masters as he saw off Viktor Troicki in just over an hour this afternoon.
Troicki, seeded 32 at the tournament, got off to a solid enough start and led 2-1 before Nishikori raced away with the first set by winning five games in a row.
It was a similar story in the second as Nishikori broke twice more to again clinch the set 6-2 and progress.
The Japanese will either face 19th-seed David Goffin or Jerzy Janowicz in the last 16.
