The incident occurred when Djokovic lost the second set in his 7-6 (3), 4-6, 6-0 win over Murray. Djokovic was given a warning by the chair umpire after he lost his cool, who told the Serb that the outburst "didn't look good".
However, Djokovic was quick to realise the errors of his ways and made a heartfelt apology to the ball boy in a video that was posted on his Facebook page.
"I saw the replay, and unfortunately the ball boy was in the middle of it and I really feel sorry and regret that he was there," Djokovic said. "There was absolutely no intention whatsoever to hurt him or scare him in any kind of way, and I sincerely hope that he forgives me.
"I really apologise, and also as a parent I do care about children a lot right now. I look at it in a much different way, so I want to apologise to his parents as well for this situation and as a father I wouldn’t wish something like this happens to my son."
