Novak Djokovic insists he has been working hard since losing at Indian Wells and can go all the way at the Miami Masters.

Having secured a seventh Australian Open title at the start of the year, the Serbian ace looked in decent form to go deep in the Californian desert but suffered a shock straight-sets defeat to Philipp Kohlschreiber in the third round at Indian Wells.

The loss gave the 15-time Grand Slam winner some unexpected time to hit the practice courts and it seems as though he put it to good use.

“I’ve had quite a lot of court time between Indian Wells loss in singles and now tonight’s match,” he said. “I’ve worked on everything I need to work on.”

Djokovic, a 5/2 favourite to win the Florida event ahead of Roger Federer (3/1) and Alexander Zverev (10/1), returned to winning ways with a straight-sets victory over Australian Bernard Tomic on Friday.

After a tough opening set, Djokovic upped his level for a 7-6 (7-2) 6-2 triumph and faces a third-round clash with Federico Delbonis next.

There is little to go on in terms of previous results between the pair as they have yet to face each other but, at 1/25 to advance, it seems as though Djokovic is expected to win with ease.

Delbonis has been ranked as high as 33rd in the world but is currently down at 83 and the contest seems like a mis-match on paper, with the Argentinian on offer at 12/1 in places.

However the same could have been said for the match-up with 35-year-old Kohlschreiber and the German managed to defy the odds to pull off a huge upset.

Djokovic will be wary of that but, at the top of his game, it seems unlikely that the South American will get anywhere near him as he seeks a seventh title in Miami.

Whether or not Delbonis can raise his game and take a set only time will tell and Djokovic to win 2-1 is priced at 4/1.
