Novak Djokovic's winning momentum continued as he breezed past James Blake into the fourth round of the Sony Ericsson Open. The second-seeded Serbian has now won 22 matches in succession and shows no signs of slowing down in Miami, thrashing his American opponent 6-2, 6-0 to set up a match against Viktor Troicki. "I'm playing the best tennis I've played in my life," said Djokovic.

Juan Martin del Potro produced an upset of sorts in ousting fourth seed Robin Soderling, 6-3, 6-2. Del Potro next meets Mardy Fish after the American's straight-sets win over France's Richard Gasquet.
