“Honestly, I think I’m playing better and better as the tournament goes on, something you always wish for,” Djokovic said in his interview on the pitch after the game.
“You want to take the tennis level up a notch every game, so that’s what happens.
“I know I can always do better and always expect the highest of myself, but so far it’s going well and I’m looking forward to the next round.”
The frontrunner raced through the first set in just 24 minutes as he continues his quest to win a fourth consecutive Wimbledon title.
It was only in the second game of the second set that Kecmanović, the 30th in the world ranking, came on the scoreboard. At one point, that set was tied at 3-3, but Djokovic withdrew with a service break at 4-3.
In the final set, Djokovic broke twice before Kecmanović hit back with a break of his own – his first of the match.
However, it proved too little too late and the 20-time Grand Slam champion had nailed the emphatic victory within two hours, much to the delight of the crowd.
“I don’t take your presence for granted so thank you for coming and supporting tennis and both players, we appreciate it,” he told Center Court.
Djokovic will face the Dutchman Tim van Rijthoven in the fourth round. The world number 104, a wild card in the Wimbledon draw, has risen in the rankings in recent weeks before making his first grand slam appearance.
Van Rijthoven defeated Georgian Nikoloz Basilashvili 6-4 6-3 6-4 on Friday to bring his winning run to eight games.
