Duckworth is known as "Ducks" to friends and family, prompting fans to make quacking noises whenever he plays at home. During a first round match against Federer at the 2014 Australian Open, fans at Rod Laver Arena would make regular quacking noises.

This must have left an impression of the 20-time Grand Slam champion, who would go on to make quacking noises anytime he ran into Duckworth.
"Every time I see Federer or I walk past him, he starts quacking, or he calls me ‘Quack’ as well, so it’s pretty funny,’’ Duckworth told NOTE.
“I just say, ‘Hey Rog’. I don’t really have a sound or something for him. It’s just Rog.’’
Duckworth made his maiden ATP final in 2021 and broke into the top-50 for the first time in his career. In his last tournament of the season, Duckworth made his maiden Masters quarterfinal in Paris, losing to Hubert Hurkacz.
