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. “
Juan Martin del Potro produced an upset of sorts in ousting fourth seed Robin Soderling 6-3 6-2.
In what was his finest moment of the year so far, Argentinian Del Potro was in imperious form on Stadium Court to move into the fourth round and rightly proud of his performance.
“It feels good,” he said.
“I played a really good match. I served much better than in the Philipp Kohlschreiber match, and that’s what I need if I want beat top 10 players.”
Swede Soderling has lost his last three against Del Potro but insisted he was mentally right for the match.
“I’m always prepared for tough matches,” he said. “I know anyone can be a danger. I have to play well every match to have a chance to win, which I didn’t do today.”
Del Potro next meets Mardy Fish after the American’s simply straight sets win over Richard Gasquet of France.
The South American said: “It will be a special match because I know him.
“He knows my game. We’ve played many times against each other and here in the fourth round, every player is playing really well. So it will be a nice match for both.”
Fish said after his mid-day shift in the heat: “Playing out there today, you can obviously see why you need to be fit to win these matches!”
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, who next meets Kevin Anderson, said: “It’s important to get some wins under my belt before I go over to Europe on the clay court season.”
Anderson will represent an unusual prospect as he is just one inch shorter than the 6ft 9ins Isner.
“He’s not used to looking up to anybody, I’m not used to looking at anybody that’s almost at my eye level, so it’s a unique matchup for sure,” said the American.
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.
Marcel Granollers beat Michael Llodra 7-5 3-6 7-5 while David Ferrer of Spain moved through to set up a clash between the two compatriots. Ferrer beat Somdev Devvarman in straight sets.
