Novak Djokovic has been spicing up his post-match interviews at the US Open this year, and he has once again left reporters with more than routine quotes.
After dancing for the Arthur Ashe Stadium crowd in New York following his second round win over Frenchman Paul-Henri Mathieu, there was more entertainment on offer after his third round victory over American Sam Querrey on Saturday.
The Serbian is yet to drop a set at the tournament, and he progressed to the second week by beating the home player 6-3, 6-3, 6-2, but he decided to focus his press conference on another star.
The world number one introduced nine-year-old Zia Uehling, who is the daughter of his friend and former player Gordon.
Zia has written five original songs, and she performed one for the gathered press.
"If you don't mind, this is a first-time experience for my dear friend, Zia," Djokovic said.
"She's a musician. She's a prodigy, a future star and this is a very valuable experience for her. So please do ask one question."
After being unveiled to the reporters, Zia was asked what instrument she plays, which is the guitar, before a request was made to hear a piece of her material, and she sang “African Sun”, which is dedicated to African people.
Djokovic thanked his friend by giving her a hug before she made her exit, marking one of the more bizarre moments of the tournament so far.
While he is strongly concentrating on aiming to win his second US Open title, Djokovic has shown himself to be quite the performer recently, as he showed when he took up the Ice Bucket Challenge to raise money for the ALS Association, a charity that encourages scientific research into the motor neurone disease.
Many who have taken up the challenge (which involves the nominee pouring a bucket of freezing water on their head before nominating as many as three others) have not been able to address it with the same level of showmanship.
The seven-time Grand Slam winner preceded his challenge with a dance to Vanilla Ice’s “Ice Ice Baby”, and that was followed up by a jig to Iggy Azalea’s “Fancy” after he beat Mathieu on Thursday.
There is a history of the 27-year-old enjoying himself after matches in the early stages of the hard court Grand Slam, as he previously challenged a fan to a dance-off after a night session match on Arthur Ashe in 2011.
He will next be in action against Germany’s Philipp Kohlschreiber in the fourth round on Monday, who set up the meeting by defeating another American, John Isner, in four sets.
It will be the sixth time the two players have faced each other, and Djokovic has lost just one of their five previous matches.
Should he beat his 30-year-old opponent, then he will be through to his eighth consecutive US Open quarter-final.
