Seven-time champion Novak Djokovic talks about the importance of the ball toss as the Serbian scored his best ever serving performance in his second-round win over Dan Evans at Wimbledon.

Novak Djokovic returns to action at Wimbledon today as he faces his countryman Miomir Kecmanovic for a spot in the fourth round. Dan Evans gave the Serb few headaches last time out. Djokovic cruised to victory in straight sets to dump the Briton out of his home major and will hope to exact the same misery on the unseeded Kecmanovic.
