From pizzas and cheeseburgers to gluten-free and low carb diet, tennis players want that little edge over competition.
It was job well done for Novak Djokovic as he silenced Bernard Tomic and his Australian Fanatics with an emphatic 6-3 6-3 6-3 victory in the Wimbledon third round.
The top seed and defending champion could not have been more pleased with his performance as he reached the second week of the grasscourt major for the seventh year running by winning all nine sets he has contested.
The world number one will next meet big-serving South African Kevin Anderson.
Earlier, Stan Wawrinka continued his stealthy progress through the Wimbledon draw with another clinical victory as the Swiss dispatched Fernando Verdasco 6-4 6-3 6-4 to reach the fourth round.
The French Open champion, whose searing backhand is one of tennis’s most famous weapons, has not dropped a set in his three opening matches and was untroubled throughout against Verdasco.
The Spaniard, a former top 10 player, looked to be feeling the effects of two punishing five-setters in his opening rounds and came up short at key moments as Wawrinka broke once in each set to clinch victory.
