Tennis: Djokovic is having time of his life

Novak DJOKOVIC'S winning momentum continued as he breezed past James Blake into the fourth round of the Sony Ericsson Open.

The Serb, second seed in Miami, has now won 22 matches in succession and showing no signs of slowing down this fortnight, beating American Blake 6-2 6-0 to go through to meet Viktor Troicki. "I'm playing the best tennis I've played in my life," said Djokovic. "

Sixteenth seed Troicki beat Sam Querrey 7-6 (5) 3-6 7-5 over two and a half hours to set up a meeting with Djokovic.

Juan Martin del Potro produced an upset of sorts in ousting fourth seed Robin Soderling 6-3 6-2.

Andy Murray's conqueror Alex Bogomolov Jr went out to fellow American John Isner, going down 6-2 7-5 against the big man. Isner now meets Kevin Anderson, just one inch shorter than him at 6ft 8in.
