Novak Djokovic has progressed to the third round at Wimbledon.

The defending men's champion made light work of the soaring temperatures in London as he defeated Finland's Jarko Nieminen in straight sets.

He completed the 6-4, 6-2, 6-3 win in just over an hour and a half.

Djokovic is pleased with how quickly he won the match.

"On this warm day, it's good to spend a little bit less time than is possible. So I'm glad with the way I'm playing and I'm getting into form and as the tournament progresses, hopefully I'll be able to elevate my level of performance in the next one," he said.
